RC India

I had dealt (briefly) with Sharma Models in the late 80s and 90s. I had bought Balsa Wood, a Diesel Engine, and many props.

I have always had a very high regard for them. To successfully manufacture an engine of consistent, internationally recognized quality and performance, is an Engineering feat worthy of a giant corporation, and here we had a Small Industry based in Jodhpur doing it successfully. As an IIT Mechanical Engineer with 30+ years experience, I know what that entails, and have a very high regard and respect for their engineering skills.

While browsing through their site I came across the Kaiser, and, being a bit "full-up" with corro, wanted to build a Balsa model. So I phoned up Vivek Sharma, discussed with him, and bought it  ;D

Have reached this point now, after starting on 11th August, and spending 2-3 hours a day. I can post a full bild-log, with some "Tips & Tricks" if there is interest.

THE BARE BONES - A Happy Moment in a Balsa Build

I have one hand cut one lying for years ! motivated to join in (it has the old blue print too, to scale, along :)

Make it sir, should be fun (with a lot of ghassing   :giggle: :giggle:)

@sanjayrai55
I know you get up at 5am.
You are either 55 or 59 years old.
So presumably not retired from your day job.
Yet you manage build after build.
I guess like Gusty, you too need only 3 hours of sleep.

But my question is not that.
It is:
Where do you keep all the models?
I don't even have a place to sit.
Except for one sofa left for dad, others occupied by Tiger Moth, Magic, RCTLG, Corsair.
Solo Star and Fantasia on top of fridge.
Trainers on top of bookshelves.
Aermodelling mags from 1947.
Worktable overflowing.
Dining table has to be cleared 3 times a day.
Citabria, 2 Nine Eagles, sundry crates in balcony.
Goldberg Cub unopened since 1996...

Aaargh.
Do you have any space to let for a nominal rent?
Regards.

Don't think i didn't notice the rib capping. Just waiting for tissue and dope. Hopefully.

Iyer sir, my age and other details are no secret. Just click on my profile :)

For keeping models, walls are one's best friend

I give away a lot of models to encourage new flyers.

What saddens and maddens me is in most cases they take the model with much gratitude and enthusiasm, and then vanish  :violent: :argue:

Oh my Goodness. KK Sir n Sanjay Sir both of you are really Legends. hats Off

Thank you sir

nice  to see your treasure

good collection sir    {:)}

And here i thought i was crazy for wanting to die with models on the side of my Hospital bed, You sir, are much younger at heart then many people i have come across. It is an inspiration to see somebody still building in their later years. (sorry if i made you feel older). :-)

Dear Sanjay Sir,

Wish I too had such space for my models.....  I had to stop after making my third as I am out of space in my workroom.  The bed there generally has aeromodelling stuff on it or a model which needs some attention before flying.  My two models are on the wall and the third will be out for flying on the coming Sunday.  The fourth one, a 5 ft span glider (Guppy) is kept in the loft and the wing was damaged and a new one is in the process... nearly half done.... but it still remains in the loft.  My Balsa and similar other things make my movement a bit difficult in the room.  Yes my two cycles also reside there.

The Sharma's were always ahead of their times when they started to make the Engines.... then came their aeromodels which were way ahead of the ones being sold at that time.... Please read the foot note of my reply and it will tell you more about the Sharmas.... Mr Anand and now Vivek and Vishal are keeping the same flame alight and doing great work... Soon their Metal gear and carbon gear servos will be in the market.

Anyway..... all that is said and done.... I been with the Sharma's from nearly the year 1980.  Was a kid then.... but was with the Senior Sharma whenever he went flying... spent a lot of time with him learning how and what to do..... Later was involved with them when they started shifting from just making engines to models..... I flew the Kaiser (Mk 1) in the year 1983 - 85.  I had that plan with me and recently I built it from thermocol..... Thats the model I prefer to fly more and its been doing great since it took to the air in Nov last year.... Countless sorties and well... heavy landings too....  Its a foam one with a Turnigy 3536/6 1250 KV motor..... with a 4 cell its a rocket and flies like a dream...

See the older Kaiser in the picture me flying it in the local airfield....... Do please note the low slung tailplane as it was in the original design......

Happy and Safe flying......

I see some familiar tarmac

HA ha ha.... Yes I know.... Good old memories do not die....

What a wonderful insight on Sharma's Shobhit. Lucky you, to have had such a great interaction with them

Your thermocol version looks real pretty :D Isn't that a lot of motor for it? My balsa model seems headed for 1100 grams or so, with a 2200 mAh LiPo.

Gusty Saheb can recognize any flying field in the nation  ;) ;)

My Pleasure Sir. But I am really Inspired. Also I am in touch with KK Sir and he is helping me out at the beginning level. believe me he is a True Legend. Thanks again Sir.

Well dear Sanjay,

This is not a slow flier.... I do my basic aerobaatics too on it and so I need the motor.... on a 4 cell it gives the right feel of flying a good model....  Yes it weighs over a Kg with a 2600 mAh three cell or a 2200 4 cell lipo i.e. 1200 gms.  Mind you the insides of the fuselage are reinforced with 1.5 mm plywood and the wings have hardwoord spars along with a balsa spar.  Being covered in vinyl (vinyl is very heavy) cost it so much of weight.

By the way.... Sharma's not have excellent Laser cut kits for all their models......

Happy Flying...

Sanjayrai55 ,try publishing an e book of ur work,seriously it's huge & will be really a great help for beginners and pros alike

You are kind.

Aeromodelling is my Hobby, and RCI is my e-book. I'm content  ;D ;D

Fantastic job Sanjay sir  {:)} {:)}  :hatsoff:

Thanks Nithinraj  :salute:

(some of the) Deviations from plans:

1. Used 2 X 10 g Metal Servos for the wings. Made a platform for crewing the servos
2. Used 2 X 17 g Servos for Elevator & Rudder
3. Used a steerable Tail Wheel connected to the Rudder
4. Did not used the supplied covering film
5. Changed the anchoring of the main L/G; made it double height
6. Used larger (90 mm) wheels for the main L/G - rough runways!
7. Did not put sheeting at the aft bottom part of the fuse. Feel the ply is adequate

Note:

1. There seems to be a minor discrepancy in the drawing. The Dihedral brace is shown as front of the spar towards the LE in the plan, and in the cross-sectional view it is behind the spar, towards the TE. The rib cutout matches the c-s view, and I have used that
2. AUW with 2200 mAh 11.1 V 3S Lipo is 1130 grams

Kit review:

All in all a most complete kit! After a long time I have got a kit where the manufacturer has been thoughtful and thorough, provided generally clear instructions, an excellent plan, and a comprehensive hardware kit. The laser cutting is very acceptable, he parts have been removed from the sheet (this can be a painful job, especially if the laser has not gone through) and most importantly, the balsa and ply selection is well made and suits the function.

Maiden this weekend - watch this space  ;D :D :D

Oops - one more deviation from the plan

I did not use dowels & rubber bands, but made a bolt-down arrangement for the wing. Looks cleaner and cool, and has an important function: unless you put locators, each time you put the bands, the wing moves to a slightly different position, and that affects the trims

 :thumbsup: All the best Sanjay Sir! Maidens are always exciting  ;D

Thanks Vishal :D

sir, can you tell me the cost of kaiser mk2 kit? i am interested to buy one...

http://aeromodelsupermarket.com/radio-controlled-model-kit/44-kaiser-mkii.html (http://aeromodelsupermarket.com/radio-controlled-model-kit/44-kaiser-mkii.html)

Oh, my Kaiser crashed about 4 minutes into the maiden. The prop came off ( :banghead: :banghead:) and it went first into a tip stall, and then a spin. Landed in a deep hole, and the wing is in bad shape. Maybe repair, or make a new wing (Corro  >:D >:D - 2 hours)

Sorry to hear that sir,
Await analysis.
Did it not transition to glide when prop came off?
CG too far aft?
Wing loading too high for quick recovery?
Guess you'll have new wing ready by lunchtime  ;)
Regards.

Oh my  :o :o Looking to hear more. Curious as Iyer sir as to how the model didn't glide. Happened during roll/turn at slow speed?

My mistake, Iyer sir. Impatience, actually.

The prop adaptor of my 3536-1100 had actually partly sheared off some time ago while tightening a nut onto it. My 3536-1250 motor (which I had planned to use) had just packed up -a failed bearing led to a burnout. That was on the Fun Cub, so there was no problem with dead-stick - just glided it safely in a smooth landing. Ordered another, but was too impatient to wait  ;D

So used the 1100 KV motor. The nut was on 1 1/2 threads, glass was half full ( :giggle:) so went ahead. Got hit by Murphy's Law  :giggle:

The model did have a tendency to tip stall, below a certain speed. So had to keep the speed up (noticed this on some scale Piper Cubs too) Maybe needs washout - not too sure. It is a high wing trainer made into a sports by putting the wing below - no other changes.

When the motor went, it tip-stalled, and then went into a spin, leaving me a very very sad spectator  :'( :'(

 :rofl: :rofl: :rofl:

Sorry I shouldn't be laughing at this but couldn't hold myself. You have an amazing sense of humour Sanjay sir  :giggle: :giggle:

What to do Vishal? As Confucius said, if Ra*e is inevitable, lie back and enjoy it  :rofl:

 :rofl: :rofl: :rofl:

Its bad to hear about crash Sanjay Sir  >:(

Happens yaar. Part of the hobby  ;D

i had seen this trainer at sharma model very stable looking trainer , sir you had done very good construction part
   , it don't matter , take this bird again into the sky   :salute:

Sad to hear the tragic end of the model.... Anyway better luck next time.  My Kaiser (old design) is still doing great guns and in good shape..........

Sanjay sir
You are right about wash out. The hand cut kaiser's that I have flown could come to nearly standstill without stalling. Wing tip drop is normal in a stall. For the next wing try low t/c aerofoil for the wing tip. Low t/c has higher stalling alpha therefore tip stall is avoided

@rcpilotacro

Gusty sir,
With due respect, this what i found (trying to add pics). Hence confused :headscratch:

(Red is 9% NACA0009, Green is 12% NACA0012)

Iyer sir: what do these signify?

That the airfoil with the lower thickness/chord ratio will stall earlier
than the same airfoil with the higher t/c.
(At angle of attack about 9 degrees vs about 11 degrees in this example)
Need to check with Gusty sir if this conclusion is correct.

Sanjay Sir That was one beautiful model. Sad to hear about it.

With your speed, I am sure next one is already 95% completed and almost ready to take flight.  ;D

Next Maiden tomorrow :D. Multiplex Tucan :D :D

More details soon :D :D :D

Multiplex Tucan - what a bloody brilliant flyer! Successful maiden; build log and video soon. Just love that model :D

All multiplex models are amazing fliers sir.

Video: There is a tip stall tendency at slower speeds

Today morning was flying my Kaiser with Gauravag..... we both were together with our models in the air.... For me it was a new place to be flying at.  After a while I planned to land and was looking out for gaurav's VT Allrounder... and as my model turned for the approach it found a perch on a BIG peapal tree.  Well.... though it was a write off as the model hit quite hard and a big noise at the top of the tree.  Well... ran to the place and saw the model sitting very high on the top of the tree.... Luckily there were some boys there and they helped me... one of then climbed up and shook that branch.  Soon the model fell down.
To everyones surprise it was in good health and did not seem to have even a scratch.  At home I checked the wing... there is a slight damage and I will repair it today... Will be fit for flying tomorrow morning.

By the way friends my history of doing similar things date back to 1982. It is:-
1982 - 1985..... flew into trees twice... both times flying the kaiser with Sharma diesel 3.2 cc engines.  During this period was once flying the Easy Stick covered with decorative wrapping paper and aluminum foil... and flew the model into high tension wires... suddenly there was a bright flash and the burnt pieces of my model were littered all over...
Earlier was flying Gaurav's trainer and came into a landing but decided to go round.... only to hit the lone pole in the entire ground.
AND NOW THIS.......

My apologies to have highjacked this thread of yours Dear Sanjay..... but I am sure you will forgive me for that as most time i did this kind of a thing it was a Kaiser in the air.

Moral of the story..... if you are flying in a new ground look around for obstructions carefully.... always have a spotter for the first couple of flights and never never ever fly two models together for the first flight.
Best wishes.

Made a new wing - in corro  ;D ;D

Balsa wing 289 grams
Corro Wing 360 grams (can be made same 290 grams bu not using wingtips - I used the same ones)

Thats a tiger come back :hatsoff:

 :rofl: :rofl: :thanks:

ordered the pg 15 kit from lotus hobby on wednesday and collected the kit from main post office on monday (today) because the post man dont know how to bring and was afraid of breakable property of the parcel.so, he told me to collect it from the main office.
really excited to build (:|~

I notice this flying ground is the bus parking area in front of Power Grid office in Gurgaon. I spotted this place (for flying my models) long ago, but since I stay in Noida, the thought of travelling all the way up to Gurgaon on a holiday morning put me off !!
The videos are good but not showing the landings !!

sir,
can u send the picture of  upper wing kaiser mk ii model and also the motor and other required details , i would be greatful. thx pls mail on palspals80@gmail.com

All details are in the build log. Why don't you go through it? If you find going through the log an effort, you will find building it ..............

Sanay, if after going through the build log you have any specific queries, feel free to ask.

Avoid PMs; post over here. That way it could help others too

i have also bought kaiser mkII kit from sharama aeromodels

and i also bought 2.5 cc engine. I new to this field

Futher, I am taking assistance of NCC guy

but i not sure about my 2.5 cc engine

kindly recommend between  2.5cc engine or brushless motor of same strenght

kp
chd

Why don't you read the whole thread? It is clearly written about the brushless motor

Re.: Engine, let's see what your "NCC guy" advises  :) :giggle:

@kamalsahai@yahoo.com
Should i get an Alsatian or a Pug?
Depends on what you are looking for.
Economy? Performance? Ease of use?
You can get an electric motor of equal performance.
But the support equipment is different.
The running costs may or may not be different, depending on how often you fly.

If you analyse it yourself, you'll know the reasons for your choice.
If instead of analysing the pros and cons yourself, you prefer to ask others, then you'll get advice that may or may not suit you in the long run.

If you had asked a simple question like what is the electric equivalent of a 2.5cc glow, you could expect a factual answer.

Decide whether you want to go electric or glow. Both will work.

Dear Sanjay Sir,

Recently made a Kaiser Mk II with a modified fuselage... i.e. just made a nice cockpit and the upper surface on the fuselage.  Rest all remains the same.... will be putting up its pictures soon for all to see...

I been a great fan of the Kaiser and now have both the earlier model and the Mk II with me....

soon the pictures of the two will be here...

Happy Flying...

Wonderful! Looking forward to seeing it

Sir I Love you,Your planes, and your RC room. You Rock !!!
Regards,
Aman.

Dear Sanjay Sir,

Here are a few pictures of the Kaiser Mk II in the making... Though by now most of it is already done.  If all goes well.... probably the flist flight will be on this Sunday.  The fuselage is made of Japanica sheet and Blue foam (given to me by Gaurav Agarwal).  The tail surfaces are of Balsa strips and covered with computer paper (balsa sheet 4 mm given to me by Vishal Sharma of Sharma Models) and the wing out of HD thermocol taken out of packing material..... 1 inch in thickness.  Used fevicryl colours to paint it.  The connections, controls and wheels are to be put in place.

OK...... I need some advice from you... You had made the same model out of a kit and then somehow it crashed and the wing broke.  Can you please let me know what went wrong or what do you think was the problem so that I do not repete the same errors and end up in a pile up.  Your advice will be highly appreciated as it will probably same my model on the first flight.

Best wishes to all....
Shobhit

Some more....

Here are a few pictures of my Kaiser Mk I or the earlier Kaiser (it had the tailplane attached to the bottom of the fuselage).  I first flew a balsa model of this one long time back i.e. sometime in 1983 - 85.  The present one is all of thermocol (fuselage of HD thermocol and wing of commercial thermocol).  Its a semi symetrical wing unlike the one given in the kit which is akin to Clark Y aerofoil.

Hi Shobhit

I found the model had to be flown reasonably fast as there was a tip-stalling tendency. This could be offset by introducing some washout. I made a new wing in Corro, without washout, and I just fly it fast.

I of course have a vision problem when the model is a little far, so quite possibly it could be pilot error too ;)

Thanks a lot Sanjay Sir...... I too like my models flying fast and am putting a 3530 NTM motor with a 4 cell to test it.  I am sure it will be a bit too heavy on the gas... Later will reduce it to a 3 cell if all goes well.  The plan recommends 300 - 400 watts of power for the motor and mine is going to give 425 W with a 3 cell and 560 W with a 4 cell.  So lets hope that all goes well.....
Thanks for the input.... will keep the tip stall in mind and not allow it to go too far....

What KV motor, and which prop are you planning to use?

I am fixing a 3530 1400 kv motor of NTM and will be using 9x6 or 10x6 depending on a 4 cell or a 3 cell battery..

Great  :thumbsup:

Plenty of speed

So i think it has high power thats because of the motor right? ? And weight of the plane or any other also depicts that? ??
Regards,
Aman.

A good theme for the Sweepstakes, i think...

Iyer sir  :salute: :salute: :salute:

Flew my Kaiser low winger a few days back.... with a 3 cell... went perfest.... was too hot at Allahabad and so did not have the heart to ask someone to take pictures of it.  Anyway.... nest time will surely take and post them here....

Thanks my Kaiser Mk II with a remodelled fuselage...... flew it last week.... Here I am setting up my remote just before the flight......

Great Shobhit sir  :thumbsup: Waiting for some videos

BTW, don't you think you should start another thread on your Kaiser? This is a Build Log thread

well.... yes indeed....... Thanks a lot
