RC India

Hey guys!!  ;D
Recently started my next build of globemaster it will not be for sweepstakes as i will be leaving this build for a month as i have exams so here some of the pics of the progress so far..
[/b]

I wanted to confess that the last scratch build that i did was HAL HT2 which flew but was too heavy  :banghead: so this time i will not be using any hot glue only foam glue of different types(gorilla glue,UHU POR and HK Foam glue)... 8-)

Special Thanks to : :bow:

M.Kumaran sir(rcparkjets)
Nithin sir(nithinraj kotian)
Sanjay sir(sanjayrai)
Chintal sir
Kewal sir(kewalkalsaria)
Chris sir(DemonDriver)   :thumbsup:
he helped me a lot during the problems while doing my homework for 5 months  :giggle: :giggle:

This is one of my most ambitious build till date so will be a slow one as will look into every detail
so fasten your seat belts here i go :D

Ooops. I would be reaching on 29th April and would be there till 2nd May. Lets see when I could come to you. Hope your exams aren't going on right now.

Use coro for wing with the flutes along the chord. use a good balsa spar on it and have some corro ribs. you will have a rock solid wing.

sub'd! this looks awesome! Best of luck dude!

@utkarsh yeah my sat exam is on 3rd May will be busy then but lets see :)
@topalle i am depron guy no coro for me i already have planned the build :)
@aniket210696 Thank You aniket  :D
Updates are coming  (:|~

Progress!!  ;D
been working all day
1.Glued the formers and as i am using UHU means it takes 12hr to cure so nothing more could be done to fuse
2.Wings cut out and engine rib cut and glues by 3 pieces of 2mm balsa
3.Mid Section done using HD foam and joining spar glued for overnight

Fantastic work... Yash :-) all the best.

Nice work Yash... it is a beautiful build.. what do you plan to use for covering?

 {:)} {:)}

Wonderful; build :thumbsup:......

I saw that you are using Dremal's glue gun!!!   :thumbsup:....... this itself shows your quality consciousness and appreciation for highquality work.

Generally glugun is the most ignored instrument in the complete cnstruction process; :giggle:

@asinghatiya sir i used dremel glue gun only for making temperory wheel stopper for landing gear :D in all the build i have used only UHU POR and Gorilla Glue :D that's quality conscious :P
@girishsarwal sir i will used 3mm depron to conver it and for paint i am confused as i can nowhere find compressor :( for airbrush system
@nithin thank you sir :D

I used Dremel 3000 for cutting CF Tubes and rods its a fantastic tool must buy :)

I must say its fantastic build.....
as usual question where did you source CF rods??

And the DP is recent or old..?

sir i got rods from RC Dhamaka and dp is recent :D
This my fourth plane  two failed one left for maiden(FT Old Fogey) :P i have good command on bixler :)

yash :hatsoff:

Not sir, I'm just 20  ;D

i am 17 years and 8 months old so you are "sir" :D

I am 16, so I am your junior...

Thank you for NOT Participating in the sweepstakes... If you compete against me, i'll lose terribly

:P

Watching this thread with a lot of interest. Whether she flies or not, this is going to be a very impressive build.

By the way, Topalle (16), Maahinberi (20), Yash10896 (almost 18) - all you kids can call me (almost 50) Uncle / Grandpa. No problems!

great going yash! :thumbsup: i would never be able to build something like this! i'm actually very curious as to how you're gonna sculpt the fuselage... whatever method you use, im gonna use that for my next build xD :P
so what paint scheme are you going for? IAF :P
PS: i'm 17 Years and 10 months :P :P :P

Aniket, yet another nephew  ;D - pick up some depron/ biofoam plates from the market. Chop them up into manageable squares / rectangles. They are great for these jobs.

These cannot be used to make the structure or can they be used?

@VC Thank You sir i am also worried about it flying well not of the model but me :)
@aniket yeah i am going for IAF theme "Mera Bharat Mahan" :D and about sheeting wait and watch :P
@topalle reason i am not participating in sweepstake is exams :( and also it is a big build so will take time :)
anyway will leave this build from tomorrow and will continue after 27th May about to upload some updates..

yash :hatsoff:

Retracts installed and are working great still needs to install steering servo for nose
Also vertical stabilizer has been installed..

Write your exams well bhai... today i am getting my results also...

Hey friend well done  I want to just ask that how do u make the landing gear  :hatsoff:

i made it using one CF square tube approx 8cm and one 6mm cf rod..
will upload some closeups :)

beautiful build yash

All the best for your exams...

thank you sir i will certainly complete this model as i don't really like failure so even if it is not good flight worthy but then also i have many people's expectation on this build so definitely gonna complete it

Regards
yash :hatsoff:

Yash, I'm getting more and more involved with this build. Go slow, build accurate. She will be a magnificent bird just sitting there. There is a lot of reference material available on the net for the Globemaster - use it and detail, detail, detail.

Don't rush this build - she is special.

All the best.

Thank you VC sir :)
Sir i am doing my homework for last 5 months so that i can sort out everything before i am actually going to build it read lots of threads in RCG and lots of pm exchanged so its smooth for me till now :D

Yesterday was my SAT exam got the permission to work on this beast for 2 days so here is the work done till now
1.Winglets done looks scale  >:D
2.Did some secondary reinforcements of wing section using the idea of bridges where you do zigzag rod structure :)
3.Controls surfaces done using balsa instead of only foam as it is more rigid.. Balsa is sandwiched between two 3mm depron structure
4.Lots of sanding for mid section to make it more scale looking  (:|~

Excellent build yash keep it up. I saw earlier that you are planning on using the 64mm Dr. mad thrust EDF's would love to see a few pic of the power system. Also what is your expected AUW and roughly how much thrust does the edf unit provide.

Subbu

nice progress bhai

Power setup as requested by subbu sir   ;D
My expected AUW will be 1600-1800g max as only power setup is 1000g here's how: used digital weighing machine
1. EDFs-281g
2.LEDs-25g
3.Retracts-120g
4.ESCs-120g
5.Miscellaneous-80g
6.Battery-300g
7.Servos-60g
Approx:1000gms

Each EDF at half throttle will produce 700-800g of thrust(so 1400-1600g thrust expected) and being a cargo plane for scale flying it requires 1:2 thrust to weight ratio so there is no problem in it :) ....

 ;D yash, sir is to be used for people who have earned it for example sanjay sir.

As for the electronics they look really good. I want to know a little more about your battery system I saw at the beginning you mentioned 2200mah nanotech. I am assuming you are using 2 3S's one for each edf is that right?

Subbu

no sir i am using 4s 2200mah nanotech 45-90c larger C rating battery required for so much amps each edf will take about 45-50A and 2.2*50=100A constant so no voltage problem there but using one battery will surely reduce flight time....
i am making battery type y-connector which i got the idea from a flite test model don't remember the name but it was twin engine one...

Regards
yash :hatsoff:

Just a thought don't you think it would be simpler to power each edf with its own battery no need for a y cable then. From one of the ESC's just remove the positive wire and then y cable the 2 ESC to Rx wires. I used that setup on my 747 build a while back and worked fine.

Subbu

Battery Y (parallel) connector may help situations where one battery fails or is at a different charge level than the other ... a little more wire load though...

Are the edf's counter-rotating?

@girishsarwal sir nope they are same side rotating and will take subbu sir advice of removing positive from y lead....

Any more suggestion are surely welcomed :)

Giving small amount of time of the day for solving different build problems and one which was a mojor one was naccelles as very less information is available on internet about building naccelles with foam everybody builds with fiberglass but its messy one and i am not confident with it so made like 5 prototypes before i found the correct one tried on HD Foam with hot wire foam cutting but didn't succeeded so then tried with shaping like cone but that also didn't worked and finally with did work has taken my whole day its a long route but made me reach my destination :)

So here is pics of it before sanding and after epoxying(if their is any word like that :) ) it sanded for like half an hour nonstop then final result was satisfying :D

Regards
yash :hatsoff:

P.S i said that i am busy with my exams and yeah i am but giving like an hour at late night is not a big deal or is it  ???

@aniket Thank you buddy  :bow:
@Prashant no buddy i am just a beginner they are more experienced builders than me :)

@yash10896
Wish you had used long thin strips to plank the fuselage lengthwise instead of crosswise panels between bulkheads. Would have been much better structurally.
See for example balsa planking on gajjark's boat hull.

Anyway, since fuselage is nearly complete, two suggestions for you to consider.

Try to put in a few longerons, ie, continuous wood/cf strips from nose to tail. Use bamboo strips if necessary.

Cover the fuselage with glass cloth of less than 30gms/sqmt, using finishing epoxy. I am able to keep it down to 10gm/ sqft by scraping most of the epoxy off with a credit card before it dries.
If you dont have finish cure epoxy, use Touchwood or Wonderwood PU. not so strong, but works.

Since this is such a labour intensive project, take every precaution. Best wishes.

@ Iyer sir thank you very much for suggestion i really need all i can get from seniors as regarding stuctural integrity i have considered your suggestion and used bamboo skewers for connecting 3-4 formers length wise...
 i am really not confident in fibreglassing but will keep in touch with you for step to step process and i really want to fibreglass it i have fg cloth bought from hk and i usally use araldite as epoxy but i am looking forward in having a good chat with you  :bow:

I have done the upper sheeting portion and battery hatch made in front section for correct CG used pinned hinge and one servo horn to use as pull/push :D
here are the images of that :)

@joeblack Thanks buddy :)
@sahil Thank You for compliment but again i am saying there are more experienced people than me its just been a year since i got into this hobby :)

sorry guys could not post updates as was busy with other works so done very little this weekend to the beast
the thing which has to be done next was nose and tail section glued the hd foam onto it and will keep it to cure for overnight and i will tomorrow sand it for correct required shape...
i was able to laminate the horizontal stabilizer where i glued two 3mm depron on each side to hide wiring and cf rod..
I will also be doing the putty work tomorrow and will give a nice finishing to sheeting work..

REDUCE AILERON SERVO ARM BY 50%!
Unless you want rolls on take off.
Need to be careful, man, after all that effort.

sir i didn't got you exactly but i think you want to say that i should reduce aileron throws?? like make the push rod closer to bearing???

will be greatfull to receive more advice :)
Regards
yash :hatsoff:

Yash,
That long servo arm is ok for 3d. Not for this.
Reduce the throw drastically.

ok sir will reduce the throws like 20-30% ok??

@yash10896

what date you expect
for the first test flight

i think july 1st week or so as my brother-in-law is major in army and he is coming to lucknow to meet my sister(his wife) so i can go with him at army ground :) and fly this beast in peace :P

@yash10896
Can't you test it at Butchery Ground?
Where is the Army Ground?

sir he told me that beside his office he has a huge ground don't know its butchery or not but its has atleast 1km radius :)
also sir it can't be tested in june as my hk parcel is on its way with battery and silicon wires and also i still have to make another naccelle for edf

Good going Yash...
If you don't mind I'll come and join you for the maiden whenever you've planned for it.
Now seriously want to see this flying.


 :hatsoff:

Hey Yash Man this is my first reply in this topic man I have no words to express this is so awesome project man
have to salute you :salute: :salute::salute::salute:
Really I would love to see its flying video and pics of when it would be completed :)
Regards,
Aman

@utkarsh yeah sure buddy you are most welcome :) no exact date for maiden but tentatively it will be in 1st or max 2nd week of july :)
@aman thank you buddy and no need for salute it is just the things i enjoy building than flying :D

ok, would stay in touch with you this july.

 :hatsoff:

Leading edge is yet to be sanded right?

@topalle yeah its left to cure overnight and then putty is applied and sanded.....as i am out of town for a week so no update till then.....

sorry guys for not posting updates currently i am too busy with studies as i don't find time to work on this project..
and i am also stuck on the receiving of hk parcel as it is not shipped yet i will probably get it by 15-17 July so no important work to do on it.. if i get time this weekend i will work on other nacelles,sanding of LE of wings and proper installation of LEDs..
hope you understand my situation :)

Marvellous build  :thumbsup:

Sub'd! Nice project there Yash, good going!

I too would be starting the model building projects soon, btw in the process already but I am a balsa guy. Waiting for some balsa to stock up in the LHS. All the best!

very nice

@harsh thank you sir :)
@tantragna thank you sir and all the best for your projects... i have also used a lot of balsa in this project approximately 4sheets of balsa for missc jobs :)
@rcnitesh thank you :hatsoff:

I'll be here in Lucknow this month as well. keenly going through your threads on a regular basis. So, if you permit as we'd talked earlier I would visit your place for seeing this model and ofcourse such a great DIYer...

@utkarsh sure you can visit my home :) you are most welcome
i live in sahara states,jankipuram will notify you when will there be noone in the house as its the best time to talk about rc :P

Regards
yash :hatsoff:

Then its done... We'll meet some day... ofcourse when no one's at home... best time to talk about RC... ;D ;D

UPDATE!!!
so as told earlier now it will be dead slow build :giggle:
what i was able to do this weekend was sanding and just sanding its a laborious work...
sanded the LE and some portions of wing for smoothness and now it looks like a single wing not three parts of wing(mid section and two seperate wing)....

anything you guys like to tell me to make this build more interesting is always welcome :)

..........do you expect this thing to fly ??????

when will you start the paint job

   what in your mind is it going to be Indian air force style or in other colors

what is decided wing to be folding or fixed

@shobit yeah i will fly for sure i have everything in mind cg,thrust,weight you don't worry i have done my homework....
@wingmanbunty no date decide for paint but yeah i will be iaf scheme for sure.... and it is fixed wing which is detachable ofcourse mounted by magnets and screws..

It will surely fly and that too majestically,just be positive guys!

same was quoted to Hughes when he went on to build the Spruce goose..

@Priyum Thank you for giving me confidence :) ... i really am happy that some people are still there who encourages beginners :D
@tantragna sir that was really touching and please don't compare me Howard Hughes he was a mastermind and i don't stand up a little upto him :)

Well dear Yash..... All I can say is best of luck.....
I say so because I am a  lot concerned about the overall strength of the fuselage, Fin and the Wing.  Though I make smaller planes than your but I do use Plywood or Glass Fibre cloth with epoxy to provide strength at a lot pf places.... my wings are far stronger even if they are just 4 - 5 feet in plan....

@shobit17 sorry for not clarifying but i will be fiber glassing the fuselage... waiting for finish cure epoxy from hk as suggested by KK Iyer sir... i think you was not aware about it :)

@yash10896

your project is a winner from the start keep going bro.

big power comes with big responsibility.

@wingmanbunty Thanks bro ;)

Well... your wing too needs more strength.... the wing loading is going to be enough to breast the present setup.... You may consider using a hardwood spar along the top and bottom of the wing along with balsa LE and a TE...... the centre section would be ok if it is given a layer of glass fibre..
I have broken many a wings while doing aeros..... and the latest was able a month ago... repaired the same wing with a vertical hard balsa 5mm spar....all along the center section and up to more than half the span...

please see the whole thread.. i have used balsa spar(6mm) on center line and balsa ribs which are way stonger as they are 6mm each... and for LE i think foam can take the pain of that and also i will be fiber glassing the whole wing and fuse....

UPDATE!!!!
Just reached home after coaching and here i got my 1st parcel :D
my batteries are on its way from Malaysia and it is coming by surface instead of air so it will take time...
this one was from Singapore post via chennai and i recieved withing 9 days from updation on singpost website
so pretty good service....
i am so luck more than 8 parcels came with mostly 1.5kg-3kg ones and still never had to pay custom even for bixler :D
will update you guys about the work on c17 :)

Why not lets test your model with two 3300mAh lipos with me each weighing 260gm?

 :hatsoff:

@utkarsh please have patience buddy :D
i know you are excited to see it run but first i have do some electronics work which is mainly soldering and for that i got wires and heatsink today..
without proper electrical connection how will we run it :P
so today i will try to complete all soldering work and will build other 3 nacelles for edf's which is leftover job...

Regards
yash :hatsoff:

Ok. but keep on updating.

I have been silently following this build for a while now, very few times when i have been this excited to see something go up in the air.

@teamnamibia Thank you sir :hatsoff:

UPDATE!!
Soldering done it was a lot of work as my main concern was battery y cable which i did first time...
it took almost 3hrs + one burned finger :P
made edf motor extension 6 nos for 2..
also soldered ESC's wire...

so yesterday was my day off in coaching so did some important work
naccelle made for 2nd EDF and installed on wing using araldite epoxy....
did wiring of led's,servo's and motor wiring....
mounted new screws as before it was M3 which doesn't seem strong enough so i had gone for M6 ones..
mounted a switch for led as it brightens even if tx is off when connected with battery so i had gone for this type of solution....

P.S just got my first finger cut of this build where for the first time i was not using glove while working with knife :P

 :goodjob:

What purpose are you using the switch for? If it is from an old-school model/receiver battery switch, used between lipo and the rest of the electrics, better take it off the circuit completely.

They are not rated for high power circuitry and just for the Alkaline/NiCad's, which does not load up the switch. Even back in those days, the switch was considered fancy as it only increases the points-of-failure.. It is always advisable that you consider to minimise the points of failures while designing/building anything for the matter that operates critical systems.

Note: Critical systems means, for us in such as airframe-design in an aircraft, its control systems [like elevator, ailerons,etc], communication systems and it has the same interests like in medical electronics, disaster control systems, etc..

Points-of-failure means, all those components that are involved in a system which could impair the system off its fundamental purpose, for example, between the servo and a control surface [say elevator], we can minimise/limit the number of components used that may not be necessary altogether for functioning of the system. As an alternative, you can just use a metal wire [as push rod] with both the ends bent as Z between the two horns and reduce/completely-takeoff the use of clevis and thereby limit the points of failure, in this case the clevis as they are "not must have's".

Clevis has its advantage when it serves the ease of usability to detach/attach the joints in case the servo and the removable part [maybe the wing] that can be used during transporting back and forth to the airfield/hanger. So in such case, the clevis will hold the position of the trimmed position with the ease of field de/linking the actuators to its intended terminals.

Ok back to your story, in short you may directly connect the battery terminal to the Esc or any drain source it has to be connected and thereby lessening the chance of failure by one point [here in this case, the switch].

PS: Your soldering/electronics skills are commendable! :goodjob:

@tantragna
sir thank you for that helpful information about the right usages of switches :)
but sir as i have quoted above i am using it for LED which is not a major component....
 and the switch was bought from hk few weeks back

had not read the entire post, just pondered around your pics and was little worried on the scene of the switch.  :giggle:  Oh yeah.. just flashed my mind I need to get one set of switch for my model now, inspired from your work i should say..  {:)}

Amazing build  :o :hatsoff: (:|~
Have you done the nose steering mechanism? If yes, can you share a snap of it with the nose landing gear? A video is more helpful :D

And again, thats a outstanding build! You should have participated in sweepstakes!

@vijai Thank you sir for the appreciation  8-)
yes i have done nose steering mechanism and uploading the pics i will do i video of all working components after finishing it...
i have used Emax 9gm servo for steering using push rod with clevis binded to one end as my retracts came with nose steering arm so not much complicated work there its easy peasy  :giggle:

Great! I was thinking of doing it for my coro plane (I know it isnt needed. but I just want to experiment). Searched internet after posting here. got lot of ideas. But what channel will you use for steering?  :headscratch:

P.S: No sir. Again a young blood here  :giggle:

ok buddy no sir :D
i use channel 7 of fs th9x its a flip switch you have to programme it like "throttle hold" in AUX ch 7....
if you need help pm me :)

EDIT : sorry for the confusion guys but i use steering of nose gear using a y-cable with rudder so when rudder moves right,the wheels also moves right u have to change the servo horn pushrod location for synchronizing it :)
hope it helps

Regards
yash :hatsoff:

@yash10896
Did i mention sometime back that the servo arm on the aileron servos is too long?
Shorten it else too much movement on aileron!
(Further, as a general rule, the horn on the moving control surfaces should be as close to the hinge line as possible...)
Hope you got the epoxy for fibre glassing.
Can you also mention wing span, chord, weight and EDF/motor size?

sir i will reduce it for sure i remember what you told me about that don't worry sir :)
and for horn sir i did research and found that for scale transport aircraft flying it required less throws so i think there will be low deflection angle on ailerons...
i got epoxy 2 bottle each of 130g for fibreglassing should 1 layer of 18g/m^2 will be enough or 2 layers...
 i will go for 48g/m^2 for mid section of wing as it requires greater strength...

Specs :

fuselage: 1500mm
wing span:1405mm
naccelles: 74mm
edf's : 64mm

And here is some pro information specially made for you Iyer sir using 53 paper on ipad :)

Haha.
Everything i need for an afternoon of headscratching!
Except wing area and estimated all up weight!

Remember to include the area of the wing intersected by the fuselage. Your 2 half spans of 650 don't add up to the total span of 1405.

I think you may have already come across this:

http://adamone.rchomepage.com/cg_calc.htm (http://adamone.rchomepage.com/cg_calc.htm)

Remember that all initial homebuilds have a risk of not flying. If you let that stop you, there would be no progress. So carry on regardless.

1. Reason for horn position
2. Suggestion for cockpit interior!

sir half span add upto approx 1300mm and rest is mid section hd foam which u forgot :D
and sir i saw that german guy paper build its fantastic but i can't compete with him on this :)
and thank you for that valuable information about hinges,horns and servo horns :) thats really helpful....
 sir i will calculate wing area sorry for that and AUW will be 1-1.3kg that normal in these airliners build that i scrolled over on RCG and chris sir (demondriver) also told me that in airliner weight to thrust ratio can be 1:1 or 2:1 so no problem there as edf will produce 800-1000g of thrust each on 4s...

i have installed the electronic and wiring in fuselage now will work on other two naccelles which would be dummy ones...

(http://i1329.photobucket.com/albums/w556/yash10896/DSCN3244_zpsb26b34dd.jpg)

Yash,
We MUST have an estimate of the wing loading.
You have to calculate the total wing area and weigh the entire project till now. Then estimate weight added by fibre glass and epoxy.
Flying depends on wing loading more than on power loading. Even gliders can fly!

If the wing loading is low, it can fly on very little power, say on thrust as low as 0.3-0.5 of the weight.
Remember it is not a helicopter that depends on thrust. It is an airplane that flies on its wings.

The speed reqd to fly safely depends on the stall speed, which depends on the wing loading.
Need to estimate the minimum speed reqd for safe takeoff and cruise (approx 2-2.5 times stall speed)

The issue is not whether your motors can lift the weight. Not looking for vertical takeoff.
The issue is what speed the wings need to lift the plane safely, and whether your motors can provide the necessary speed.

the data is as follows:
Wing Area: 412 sq.in
Wing Loading:19.55 oz/sq.ft
Wing Cube Loading:11.6

i have less knowledge in this field some more elaboration would be helpful...

P.S my weighing machine (SF-400) died few weeks back don't know why so right now i have no means to calculate weight last time i calculated it was approx 560g of frame+retracts ordered today a new one till then i can only assume...

You may need 60-80kmph to lift off!

You also have to put straps around the mid point of each wing...
Hang it withthose straps...
Then put straps around the fuselage ahead of the LE and behind TE...
Then hang weights from them...
Equal to the AUW times 2,3,4,5...
To see how many Gs the wing and its spar can support, before breaking!
(This is what Shobhit17 sir was warning you about)

An airplane designer's life ain't easy, eh?

sir don't scare me about these things please i didn't got you on those strap things but yeah i have seen tested model which fly with this kind of dimension maybe it risk but risk worth taken...
now its too late to step back may anything happen but i will get this thing in air thats my promise....

@yash10896
Those straps are just to check if your wings can take it.

I think your 2 EDFs will provide enough power. But your 4s may add too much weight.

Just take care of a few things:
1. Can the wings support 2-3 times the AUW?
2. Is the wing loading too high?
3. Is the CG right?

Do taxi tests first, gradually increase speed till you get lift off, then cut power.
After 3-4 attempts, you'll know the speed required to take off safely.
Expect to see video of success onSunday night!

Thank you sir for that advice i will test it...
sorry i was little emotional on that reply cause i promised mummy that i will make this thing and it will fly she always supports me in this field as it is an expensive hobby and spending 10-15k on a single project in hole in pocket but they never opposed me on spending so much money they just want me to learn something that is different than others so i am very much passionate about this project i have been doing research from like aug'13 and going through around 50 build threads of airliners line by line gave me a lot of knowledge and different ways to get things done...
i have exchanged several pm's with sanjay sir,nithin sir and others too to assure that what i am choosing is tested...
It may happen that it could get crashed on maiden but it doesn't matter as far u have made something that is unusual and people are appreciating it so lets leave it to almighty about being it airworthy :)

Regards
yash :hatsoff:

Don't rush it.
Do it step by step.
Do the taxi tests first. Then you'll be safe.
Care:
Do not let anyone pressurise you.
Taxi as much as reqd. But take off only when you feel ready.

okay sir i will keep it in mind...
taxi suggestion was also given by chris sir....
he has done several builds and all he says is just experiment :)

one question is their...
my batteries are coming through malaysia post surface mail it say on website for india it take 4-9 weeks that really worries me as it was shipped on 7th july and all till now it say send item abroad next location kochi so have anyone had this experience so far as till now all my parcel came through air mail this is something different...

Where are you on rcg?
I am on rcg but don't see all threads.
Also i don't see regularly.

I get my batteries from Adiboy whenever he drops in. So no problem.
I've told him to come to my house whenever he has time, and bring whatever he has.
Takes care of 90% of my reqmts.

Try him.
Nowadays he is half in Indore, half in Delhi.

My recent parcel also came by surface mail via Kochi. I ordered on 9th May and received it on 18th July. So yeah, about 9 weeks.

@maahinberi sir thank you for the information so i think it will be here in september first week thats too bad.. all things are done and i just need batteries as edf is of 4s config and i don't have a 4s battery :(

Some real Globemasters C-17 have come to Delhi yesterday for induction to the IAF and Jaitley went to inspect it. I think you should have also gone for the inspection.

you should have bought one locally...

@topalle can u please provide me a genuine link for a lhs stocking it.... 5000mah ones

what would you say about this http://www.rcbazaar.com/products/2268-wolfpack-5200mah-35c-148v.aspx (http://www.rcbazaar.com/products/2268-wolfpack-5200mah-35c-148v.aspx)

I was about to post that one...

i dont like wolfpack please only turnigy or haiyin high quality packs
and thats 5k what i have bought is of 2k more than double

Ask mr chintal of rcmumbai...
he must have these

i have regular talks with him good friend of mine he doesn't have it anyway its already on its way so all i can do is wait and wait...

Where are you going to fly this big boy ?
Even butchery would be small for this

@multiwii lets see sir :)
atleast let me make it to run first then i will give up a call to my borther-in-law... :)

Okay

One more Lucknowite on forum..
@multiwiihelpreqd: Welcome...
Where do you live?

@KK Iyer sir i was thinking about reinforcing the wing with cf rod under the wing section so that its all rigid.....
attaching an image of how i was thinking it to be placed.....
i have also conveyed this problem to chris sir(demondriver) and he told me for 4.1lbs(1900g) AUW and 55inches(1390mm) wingspan its all good and recently i have measured it to be 1400g without battery and battery is 500g so i thinking it should fly fine and adding a reforcement could make it more rigid...

Looks nice. {:)} {:)}

How are you going to hold the wing and fuselage together ?

@devang i gave glued a piece of balsa dowel at one end and magnets underneath plus also will be using wing screws to hold it firmly...

Nice idea . Hope it works .

love to see lots of wire and joints  (:|~ (:|~

@wingmanbunty i too love the electronics part the most :D

Have you checked whether two edfs give enough thrust or not?

keeping two dummies reminds me of
http://www.rcindia.org/electric-planes/61-inch-boeing-747-300-electric-ducted-edition-build-log/ (http://www.rcindia.org/electric-planes/61-inch-boeing-747-300-electric-ducted-edition-build-log/)

@topalle yeah i have checked it before i bought the EDFs its the basic thing for beginning of a project you need to do some math calculations for a working model....

for these model thrust to weight ratio should be 1:1 or 3:4 and each edf will give 0.9-1.1 kg thrust so easily i can achieve 1:1 ratio...

In the link I gave above, the builder had made an underpowered model so it didn't fly ver well...
Good  that you checked...

@yash10896

some more add on power in our hand is batter idea for the success of so much hard work

@wingmanbunty sir i think the edf which i chose should be sufficient if not i will order new one for better performance but now also i believe it can provide enough thrust to make a scale flying possible...

also being a high wing plane it creates more lift and more stable to winds...

@yash10896
Sorry for delay in response. Been busy at work 12 hrs a day, and Gusty Sir was here yesterday!

I fear that an exposed spar like that would be just like a spoiler for reducing the wing lift.
Much better if you can sink it into the wing surface.

Why the sudden need for a spar?
Were you not going to glass the wing?
If you really need wing strengthening, why not a flat strip of carbon fibre on top and bottom, which will hardly protrude above the surface?
If you don't have CF strip, even FG tape may suffice.

Have you tried to check whether the wing is strong enough (in bending) to support at least 2-3 times the all up weight?

I think that he is just using that pic to show us where he wants to put it .

Fine if its inside the wing and in line wth the MAC (as per his hand drawn pic ;D)

 :thumbsup: :thumbsup:  :iagree: :iagree: :iagree:

More importantly, it seems to me that on this forum,
there is too much emphasis on the thrust required, and hardly any on the wing loading.
The full size c-17 has a power loading of only 0.4!

Based on the type of model, and the performance expectation, we need to decide if it is going to fly on the wing or on the power.

You would have realised that i belong to the flying on wing school (old school?)
And that i do like models that have a power loading of zero  ;D

See, the power required depends on
The drag and the desired cruise speed.
Which depends on the stall speed.
Which depends on the wing loading!

Which is why whenever i get a query on the forum, the first thing i ask is what is the AUW, what is the wing area, and so what is the wing loading.

(Sometimes i ask what is the cubic loading, but that is another story...)

Am trying to locate the video of a large thermocole jet that took off in less than two fuselage lengths.
Not vertically on power, but horizontally on the wing. Will post when found.

BTW, if Butchery Ground is too small, you need to build a different model. Or go to Bakshi! (We used to go there too, you know!)

@KK Iyer sir thank you for that reply and i too was against the round cf tube it was just for explanation which i borrowed from bixler wing spar...
i am ordering flat cf rod from RCD and other bunch of stuff..
i am also gonna fiberglass the fuse as well as wing and will be doing that after 14th aug as i will be having 3 consecutive holidays from coaching..
i dont think wings can handle 2-3 times of AUW as its too risky for time being i will test it after fiberglassing and flat cf installation...
and sir i dont think the ground in which i will be testing is small...
my brother-in-law has a different field i think which is not allowed to public he will help me through it or otherwise i will go as u suggest near bakshi ka talab their i also have a farm house near which it has lots of open space so i am not worried about that....
any other thing you think i should add for better flying is always welcome...

one question does it require two layer of 18gm/sq.in fiberglassing or one layer will do.. same applies for fuselage
please try to answer it as i am very new to this thing....

Regards
yash :hatsoff:

@yash10896
18gms/sqin?
Must be 18gms/sqm!
My RCTLG balsa wing has only one layer. It is strong enough for high speed catapult launch even without any spar or dihedral braces. Also strong enough to survive hitting an electric pole without even a dent.

Weight addition for about 400sqin was 28gms.
I covered it in 8 separate pieces of 12"x4" each. Larger size may be harder to do.
Initially i needed 5gms of epoxy/hardener mix for each piece, but as i gained experience, i was able to reduce it to 3-4gms.
You will need plastic/thermocole cups and a digital scale to accurately measure such small quantities.

(You still have not told me the expected wing loading  ;))

I suggest you test the flexibility of the wing after the first layer of fibreglass is cured. If not stiff enough, you can add a second layer to the center one third of the span.

Best of luck. BE CAREFUL ABOUT POISONOUS FUMES.

sir wing loading will be approx 20 oz/sq.ft....
it is little greater then what i thought that it should be like 13-17 oz/sq.ft...
i also think winglets should also play a major role in providing lift as they remove the tip vortex which provide drag so sir i think it should be okay
i know it is little close to sports plane wing loading but nothing can be done now....

So first of all Happy Independence day to all Indians on the forum :)

I finally got time to do the CF reinforcement on the bottom of the wing...
i got Cf flat rod from RCD and they was small in width then suspected :P
so used two of these flat rod and glued in ARC shape so that it can be more rigid also it was done in vertical postion as in vertical position it cannot bend horizontally making nearly impossible for the wings to bend due to force...
used gorilla glue as i ran out of araldite and today all shops are closed...
And the ARC shape idea arrived to me by viewing a video of flying wing on flitetest where they used gf rod for the same reinforment :)

Next is fiberglassing which is now extended for another week  :-\

Finally !! , I was just thinking about your plane yesterday !

Yash
Butchery tomorrow?
BTW, in reponse to your pm, we were in Indira Nagar 1982-87, and in Gomti Nagar 1997-2009!
At least my family was, while i was elsewhere.
Still have an incomplete house in Lucknow full of vehicles and airplanes...

Wow ! Another lucknowan ! Whom had a secret identity  :giggle:

Iyer sir i would feel honored to serve you while you are in lucknow...will show you cool places other than rc world :D
there have been drastic change in the look of city you would feel surprised..
i was in indira nagar from 1989-2004 in gov colony..sec 24 i think
and sir due to coaching(resonance) at 8-2pm i hardly get time to do anything after so much work of coaching..
thatswhy i am ignoring this project for a while because career is more important right now :)

And I live near Indira nagar ( Mahanagar ) ! ;)

And my friend lives in Jankipuram !

Ashok baijal, co-winner of sweepstakes is another old Lakhnavi (>50 years),

In 1983 or 84, i remember flying a demo for the CM On 26 Jan or 15 Aug at Butchery. NCC Air Wing gave me blue overalls (that i still have) to pretend i was part of their team.

The then NCC Air Wing boss was one Wing Commander Kondal, whose house was next to Baijal's and about 50 ft from mine in A Block, Indira Nagar.

Small world, isn't it?

It is sir , thanks for the history .

Devang,
Understood.
History has a place, but that place is somewhere else, not here, i guess. ;)
So no more...

update it is :)

pushed my boundaries of time and exactly after reaching home and doing lunch i had put my time into this bird :D
coupling yesterday's and today's work i am posting here
i did the rest of the two dummy naccelles today and installed them on wing section..
this was important part to make a step towards fiberglassing..
now only i need to do some work on fuse's mid section and then its ready for fiberglassing :)
i also have a question Iyer sir does it requires two layer of 18g/m^2 or one will do the work??

@yash10896
Hard to say, but my experience is that even a single layer adds tremendous strength to foam, especially if the thickness of the wing is more than say 1/2-3/4".
Did you finally install a CF spar? If so, one layer should be enough.
Caution: do not test the wing by bending it till the resin is fully dried!
Use a plastic card to spread. Target is 10gms or less per sqft.

5th october?
actually, I'll be there in Lucknow only for a day or two. I'd to go for my SSB preparations.

Might be I can visit Iyer sir(if he dont minds) in Indore after my SSB is over.

Utkarsh, Welcome. So far only Gusty sir has visited us.
Yash, i have no personal experience with winglets, so unable to share any gyan.

I wonder how did I miss this thread. Interesting read and lots happened before I have joined the bus.

Commendable. Good progress and great effort Yash.

I hope you are using a sanding blocks for sanding the foam. Good practice is to use two to three flat blocks with sand paper of various grit from coarse to fine. So that you can sand them in that order and get smooth finish then evenly.

All the best for the maiden.  ;)  ;D Where is gusty when the test pilot is required.   :giggle:

Thank you Sandaram sir for the encouraging words.. :)

yes sir i have like 5 sanding blocks of 60,120,150,220 and 320 grit... made by sandwiching three 10mm depron rectangle pieces and stuck by hot glue...

and regarding maiden sir i seriously need a pro test pilot like gusty sir :D
i am very tense regarding maiden as 5 months worth hard work could be in pieces in just 5 minutes  :-\
lets hope it behaves like a trainer being a high wingers that was the only point for which i chose c-17 as all other airliners are mostly low wingers..

Will search for a experienced pilot for this bird in lucknow and i can always use our lucknawi nawabs like Iyer sir and Shobit sir for maiden :D (i am pretty serious Iyer sir :P )

@yash10896,
Carried the C-17?
Right site for PSS!

Oh!! seeing your photographs I am missing my old station so much now.

Visit Ri Kynjai Heritage resort by the lake, Visit Shillong peak,  EAC AirForce Museum and lake, Chirapunji, Smit Valley.

If you have time go for Eco tourism stay in valleys of Meghalaya Combined with Angling, Trekking, white water rafting.

Handsome young man and a [unmaidened :giggle:] beautiful plane.. enjoy the scenic Shillong!!

Back after a long time. Such a beautiful model. Well done. Eagerly waiting for the maiden.

@Iyer sir no sir the reason was the required dimensions and dangerous goods were not allowed -_- 
@Sundaram sir i surely agree that it's one of the most untouched and peaceful city i have ever visited...  Its a place to be missed... I will surely visited air force museum...  :)
@tantragna sir thank you for compliments :)
@rohitgupta thank you sir :D

I thought that you would be taller and more muscular . ;D
But the hair style is great !!

I am 5"8' how tall u want maybe it's camera  :P

Is 8''8' okay with you ? (I'm just joking)

Awesome build, it looks very good. Great worksmanship {:)} {:)}

Everyone is eagerly waiting for the maiden, dont worry it is going to fly well. :thumbsup:

And devang, yash looks short because he is standing beside the huge bird hes made. A man looks short because his creation is big.

Should we read these as 8 feet 5 inches and 8 feet 8 inches?
or is it more like 5 inches 8 feet and 8 inches 8 feet :P

Anyways, good job Yash. Keep it up :thumbsup:

Srry writing error sir :P
But i must say some people still follow others blindly :D

Hey yash, have you maidened? How was it?
If possible could you share some pics,videos

How come I didn't stumble upon this thread earlier,
This is a very nicely executed project.
I too have the barebone made and kept for a rainy day in my attic.( I made a small prototype and posted a thread earlier)
For the exterior, there are thin sheets of rubberised foam, 1mm, 2mm and so on in thickness available here, super light, tough and flexible like a paper. If you could source those out, your external fuselage would look much more appealing and beautiful.
Keep up the good work!! I know the feeling of flying something as big as the flier!!

nope not yet..not getting time due to studies..
i have to fiberglass it and as soon as its done i will update the thread..

Hey Everyone,

Sorry that I have been away from this forum for the past 3 years and recently I came to realize that all the pictures of build are hidden.
So, I am attaching a drive link for all the previous build pictures if anybody was trying to look for them.

I couldn't find time to work on new aeromodelling projects in my B.Tech period and now I am in Sweden for my aerospace masters. I hope to try new scratch builds after some months and would be very eager to share them with everyone here. Because of this forum, I always had urge to do something new and challenging and I wanna thank every senior member who inspired me to get into this field.

Stay tuned, My hands may be rusted but I ain't dusted.  :hatsoff:

Regards
yash
