Hi Guys,


RE: Mako 3D electric delta model plane; hovering, catch and tail touch, inverted flat spins.... a bag load of fun.


Mike from our club has built this and it is so impressive, 4- 5 others have now copied and built their own versions of Mako.

I have been watching Mike too and requested him for the plans and fancy building it.. Mike has gone one step beyond, he has provided me with detailed instructions too...

Will be uploading them soon... Have a look at the videos and feel free to comment...

Cool!

Waiting for the detailed instructions!

 {:)} {:)} {:)} {:)}
nice.......plz post the plans  n specs  :hatsoff:

Please post the plans and specs.. Also a few pics.. Youtube is blocked... ;)

I want the plans too , will make it along with my future quad , after my exams are finished  :)  :hatsoff:

Hi Guys,
I will find out if someone can upload plans for me otherwise I am afraid I will just be able to scan A4 pages and leave them for you to stick them together and trace... I wonder if Mark can help, I will ask him.
Mike Pemberton's reply has come so I can share his docs and notes...;
Hi again Deepak,
Yes, please feel free to share any images of my model / CG sketch to your Rc friends in India. The word.doc of instructions is attached as requested!
Good luck with the build, if you are considering 'sinking' the lipo into the fuselage - I would suggest that you fly the model first to find the best CG position of battery before cutting the aperture.
I say this because I think that my model is a little nose heavy, which I know is always the 'safest' flying trim, but not the best for manoeuvrability!
Hence, that's why I added the comment on my instructions, i.e. note 11) Re-move CG further back for extreme aerobatics, prop hanging, etc!
My model balances exactly as recommended on the plan - but if I made another I would experiment by moving the CG further back, as I have suggested to your.  I could add tail weight but this would make the model heavier, which is not ideal for such a small lightweight models of this type - much better to move the lipo to achieve desired CG! (Incidentally, the flying weight of my model is 400g, about 14 ozs).
As you are aware the model flys great with CG as shown on the plan - but I know that this model is capable of far more, especially after seeing the prop-hanging demo shown on 'U-Tube'.
Whatever type of flying you do, just make and enjoy - after all it's not going to cost you a fortune to build, or a life-time to do so!!!
       
 Best regards,
Mike Pemberton.

Has your friend mike shared the plans anywhere ? If not how did you guys copy his plane ?

He borrowed a fellow Rc flyer's Mako and traced the actual plane to build his own. He has given me a copy of those plans.
Can anyone suggest who can upload those plans if I was to post the paper tracing to him. Then we can all share them if they are drawn as tiled plan.
Thanks
Deepak

HERE ARE THE INSTRUCTIONS:

‘MAKO’ 3D DELTA (DEPRON) MODEL AIRCRAFT -

‘MAKO’ DELTA – 26.5” (673mm) Wingspan x 26” (660mm) Overall Length - Electric Power.

This small electric delta type model uses ‘elevon’ control, i.e. it requires mixing of elevator and aileron channels to provide pitch and roll control, it also uses a separate rudder channel to control yaw. Finally it uses a motor channel to control speed of electric motor. Hence, a minimum RC system of 4 channels is required!
It is a very simple model to build and capable of virtually any aerobatic manoeuvre, including, 3D stunts, prop hanging, etc. (But are your piloting skills good enough???)

Sir , is the tracing done on a big 1m x 1m tracing paper ? Or done on multiple a4 sized tracing sheets ?

That looks pretty... {:)}

Just in case anyone needs 3d delta wing plans. You can experiment and shape them as done with Mako with bigger control surfaces.

Thank you sidewinder
 :hatsoff:

Hi Devangflyer

It is done on large paper 1 m x 1 m

Nice and simple and looks great fun. Small and simple to launch 26" span and long. I want one  :hatsoff:.

@ b4ggu can you cut the copy to multiple a4 page size papers and use a small diagram to instruct on how to join it like this

12345
678         

Then scan it all and upload it

Found these on another web site I think it the same plane, asked that web site for details.

Yeah I think you're right , pls reply he tells you

I will do devanflyer, no problem catch you soon. :salute:

Hi Devangflyer,
I requested a friend to convert to pdf and this is the reply I received; " Point on copyright is - is the design available freely with the designers consent - if not we should not copy and distribute as its against copyright - "
I will add some images of the plan see if you can follow Side Winder's suggestion;

Okay  :'(

more images...

More images....

Thank you B4ggu for those details you have supplied it gets me thinking  :headscratch:.

Been busy this afternoon and drawn it up from some the few images, did some patterns on cardboard and made this.  :thumbsup:

Not been decorated yet, weigh it at 16 oz = 450 grams. The gear consists :-
3 cell 1200 mah,
150 watt motor
small 20 amp ESC,
3 X 9 grams servos,
small 1/2 size RX

Can't wait to put some colour on it, and get so air.

Had a cup of tea then got the glue out  :salute:......few hours later end up with this ...my mako in black epp foam.

The black 'mako' of mine is from some 10mm sliced epp I sliced this afternoon, with a forward spar as well, if I wanted to make it lighter which I think I can do by, playing around with a simpler body should lose 1.5 oz - use carbon spars lose 0.75 oz. The Battery is B4ggu's 2200 mah.

The hatch is retained with a 'ice lollie stick' design and velcro pads in a few postions, and the battery can be moved around to help in getting the balance correct ( C of G ) the positions shown on fuselage side. Once your happy with the position I can then put packing pieces in and lock and secure the batteries position. Can't wait to decorate and get it flying. Better get back to the water and land plane I'm doing.

The person responsible for the original design is on this blog in Europe see the link here below;

http://www.rcmf.co.uk/4um/index.php/topic,76020.0.html#lastPost (http://www.rcmf.co.uk/4um/index.php/topic,76020.0.html#lastPost)

It happens he's been in touch with me today and I think he fly's and is a member at B4ggu's model club in the midlands in UK.       

like i said earlier building tech are similar.....Going on too good.... waiting for maiden.

Ice lollie stick - rastsaurabh -  {:)} its simple and it works, is that plane model your holding your own design? It looks good.

 Yes, you can say scratch built out of foam. Sipkill aerofoil, 2500Kv motor, 10 Amp esc, 35inch WS,850Mah 3S battery

enough power to for a decent flight..... my builts are guided more that the size of foam available rather than the design  ;D

See the flight video   http://www.rcindia.org/rc-locations-and-clubs/rc-bolt/msg165297/#msg165297 (http://www.rcindia.org/rc-locations-and-clubs/rc-bolt/msg165297/#msg165297)

Got to go to work now I'll watch your video later  :thumbsup:

Wow Mark you are amazing. I got up to find you have made the EPP version of Mako already

Please do let me know how it flies?  If you need to borrow a power set for this use my Multiplex deltas parts.

I have some 8 to 10 grams servos if you want to borrow too.

How much do you think the kit will fetch in swap meets if it was to be offered ?

Thanks B4ggu for your comments and help sourcing the info for 'mako' - from your email and enclosed drawings 11.30am to bare foam finish 9.30pm - 10 hours less a few breaks ( and talking to you on the phone a couple of times etc, etc;).... net time about 9 hrs.  :salute: :salute: :salute:

Don't know about the price, would you like a couple of 'free kits' delivered ready for Alan and yourself for your Fridays building session at your place 14th of Feb?

Remember I have to delivery also that new hot glue gun I got for you.

Cheers Wibberley  


I'll get on with B4ggu aerobatic or you.  :hatsoff:

Hi Mark,

Yes we would love some freebees....
Yes I am sure Allan would love one too...
With mine, I will cover or paint it at bottom to see better agains dull clouds background which is predominant in Leicester.

 I better order and have delivered below list of items from Hobby King for this then...

You said on phone the all up weight is 450 Grams or 16 oz with above equipment; By the time I have painted it, it will be 500 grams...

You further mentioned, as I like my models slow and steady..for slow flying 8 x 4 is better..

Is that correct ???

Yes I would say so, at all weight of 1.1 lbs = 500 grams and 180 max on tap, at 1/2 throttle it will still be a good powered sports plane.

B4ggu that logo - b4ggu - why not have that as you 'avatar - picture' ?

Thanks Mark...yes will do once you have put it on a plane. 
Ordered the motor and bits for it...looking forward to it on Friday..Cheers!!

Going to decorate mine with blue and black and a bit of white like this :

Thanks Mark for the two bags of bits.
 "BLACK EPP MAKO KITS" started... images attached of progress so far....
Second installment next week ......

Mark suggested in his instructions to join wing halves after joining fuselage, we started by aligning all mating parts, sticking masking tape at back, folding in half as image Step1 and applying contact adhesive (UHU in this case) leaving for 5 minutes and then just folding back to join. Masking tapes left as is to be removed next week with some weights on a flat surface....

Alan and Deepak enjoy you build.  Hows the depron cuts going.

Alan and Deepak enjoy you build.  Hows the depron cuts going.

Rastsaurabh - seen your video of the small wing flys well and high for such a small one. You fly at a nice open site, what time of year was it filmed/video?

Second week of build;
BTW we only have spent one evening ..approx 3 to 4 hours so far.
Allan and I meet on Friday evenings when we mess and tinker about with our toys.. D and A foamy is now on hold while we attempt building EPP MAKO..
So actually its 2nd day of build; 
Removed all masking tape..
One suggestion here, the components should be given a slight sanding front and back to remove the burnt flakes and strands left by hot wire cutting..

More progress;  Notes to follow soon..

"BREAK TIME" Time for a cup of tea and a snack...... any takers!!!

Looking good - and making good progress especially on the Indian food snack  :giggle:

Thanks Mark... 3rd Week of build;
We decided to make the battery hatch a bit extra strong by lining it with veneer plywood and than sticking the EPP sides back later...

Covered top and bottom with packaging tape, I must say as this is BLACK EPP, covering it in high visible colours is a must as compared to white EPP which can be left as is.
Can you imagine flying it without any covering on a cloudy day ...

Decided to use just 2 hinges on each surface...

The choice was either lightweight depron hinges;Light Weight Pivot Hinges for Depron/EPP 10-pack
[416067]
"These frictionless nylon hinges are an ideal alternative to hinge tape especially where tape will not stick to EPP. To install, simply cut a slot with a sharp scalpel blade in the surface of the foam and glue in place with CA.Specification: Dimensions: 28mm x 9mm Weight: 0.2g"

More to follow next week...

its coming on B4ggu

To make the 10 mm thick epp foam for this plane I have to slice the material from a 30 mm width sheet. In the past I have stood over the hot wire bow whilst I pulled through by hand to make the slices, this does take time with each cut / slice taking about 8 mins.

Solution needed to free up time so I can do something else with these 8 mins, so I made a extension to the table where the bow is attached to, this allows me to slice the foam now and walk away from it....like a 'auto epp foam slicer'.

Its made from corner brackets with screws in acting like a claw, metal weights, glass plate, here's some pictures to see what it looks like.   

some more 'auto epp foam slicer'.

Deepak

Looks like i need to get one from Mark

Gusty,
Mark calls his version "FISH" I think...
I have the profile type fuselage version as he does two ; one with profile and the other as his images above on page 2 will show...

 I am going to do my maiden this Sunday if weather allows.. otherwise one of these days soon..will give you my views.

One thing for certain, I know I am going to enjoy this cheap and chearful toy. The more I talk about it to my friends, the more I am learning..apparently it is one of the most popular best value for money plane most have ever flown..Brian who taught me how to fly 15 or so years ago told Mark how he crashed his Mako on its maiden as he had too much throws on it and this plane can be a rocket....  

I like my planes to be good slow flyers and Mark has assured his EPP version will fly slow too if set up correctly as its has a larger wing area and the wing and fuselage section is much thicker.

Mike Pemberton has advised me on its control deflections based on the EPP version;
"  Hi again Deepak,  I have been flying the Mako, (plus other planes) this afternoon at the Frolesworth site, Thursday 13-Mar-2014. The weather was absolutely perfect - the best so far this year, although the field is still somewhat wet and soft underfoot!
 
You ask what deflections I am using on my Mako - the current 'set-up' is as follows -
1) Rudder movement - approx. 30deg left and right, i.e. +/- 50mm (measured at bottom of rudder).
2) Elevator (elevon) movement - approx. 10deg up and down, i.e. +/- 20mm (measured at rearmost position of elevon, adjacent to rudder)
3) Aileron (elevon) movement - approx. 10deg up and down, i.e. +/- 20mm (measured at rearmost position of elevon, adjacent to rudder).
Hence, total 'mixed' movement of elevator + aileron - approx. 20deg up and down, i.e. +/- 40mm.
 
Hope this helps with the basic 'set-up', but obviously it depends on your flying preferences as to what amount of movement you desire. If you are at all unsure I suggest that you start with less movement, then increase accordingly as you gain experience. You can do this easily by altering 'travel adjustment' on your transmitter!
 
Good luck, hope to see you soon! Best regards, Mike Pemberton.
(Happy Landings)  "

Mikes's 6mm DEPRON plane is 400 grams and mine in 10mm EPP covered in packaging tape at wings only starts at approx 478 with 1000mah Rhino Lipos 3 cell 20C, 485 with 1250Mah Lipos 3cell 20C, and 500grams with Zippy 3cell 2200 25c.

The C and G was not coming to 175mm as suggested by Mark.

Had to make these changes;

Install ESC right behind the firewall instead of its designated slot above the wing where Mark has left a slot with EPP Block left in case it needs plugging. This block will now have the rudder servo fixed in it.
 
Remove RUDDER SERVO and install it towards the front of plane at ESC'S slot.

Had to add a thick 10mm ply firewall to bring the motor forward so a 30 gram nose weight was added and motor moved at the same time... added a foamboard pcs too to bring it further forward.

 

I suggest  Mark to;
 MOVE RUDDER SERVO SLOT FORWARD
 MOVE THE BATTERY COMPARTMENT TOWARDS FRONT

BTW I forgot to show what I have done to all my LIPOS so they stay on models...VELCRO soft side, stuck and hot glued...  and models have the same done in the battery bays with spiky side of VELCRO...

I also tend to add a velcro strap to keep them in position so the C & G remains the same in case the velro fails to hold them steady in  their place... It is a good idea to securely fix this strap underneath a lolly stick or veneer ply cut to the length of the bay and stuck with hot glue..

Cool !! most of us do that i guess

Sorry Gusty...you are an expert...this comment was only for the novices...in continuation to the blog...
We all have a lot to learn from you so some suggestions and tricks picked up along all these years of your expert flying will be most appreciated....:)

Deepak

This must be new to gusty,

Stuck the spikey side of welcro to the back of TX. this holds the tx to the back of car boot(my brother's i20 has a soft spongey type floor in the boot) it sticks well and protect the TX from damage during transport.

Ashok.P

Good one Ashok. I have done the same to my T X case. Hot glued 4 pcs on 4 corners. As you mentioned the car boot mat acts as a soft sides and my case always stays at the same place. I learnt it the hard way when sudden braking and hard turning to avoid an on coming car sent my tx case flying to write my shock flyer off many years ago.

Very nice and innovative tip...

Allan's Model is coming up nicely..
All up with battery 1300mah 3 cells estimated at 390 grams without servos and ESC so approx 45 grams less than mine 490 - 40 = 450 max..

Weighs 40 grams less than mine as he decided to move servos towards front so no nose weight and less ply.

Mine is all ready to fly..some images;

More images...
I like what Allan has done to hold the battery inside the bay..I wish I had done that too as it is much neater and secure.... So you can use your imagination and suggest another idea.. The more the better..



Might be better to start a new thread!!   I think I might just do that..

Brian Kettle test flew - maiden his 'Mako' - however he's called his FISH. It went well and he's very pleased.

Fly's great and he's well pleased -
made from 10 mm epp foam weighs 500 grams -
used lolly sticks for horns and bbq skewers for elevon and rudder edges
built up body enclosing all the battery, RX and ESC 20 amp   
he put a 180 watt motor in on 1300 Mha battery
and 3 X Ripmax SD200 servo's

Elevator 20mm each way
Aileron 20mm each way
Rudder 35 mm each way
Balance 185mm back on the wing measured from behind the wood motor mount.

Decorated with artist acrylic paints

Very nice Mark. Looks good too. Brian is a happy man. When am I going to be A Happy Man with my B4GGU that you are building for me.

You make me laugh
- I was looking at the build list and requests on my wall and were at the front  - is going to be Skim or B4ggu -- ( I't happens that I have had B4ggu on the bench today) 
:headscratch: Shall I carry-on with B4ggu  {:)}

yeh 

just -finished the 7th Mako Fish

Nice one... yes please carry on with whatever..must have them this year.. :)

I must say this Phish/ Mako is a superb flyer and has really been keeping me amused and surprised at its low level and slow flying stability... who ever is building one.... you will love its characteristics. It does all you would want an a good plane to do...

Hey Wibberly please can I have another one as a stand by... I wouldnt want to be without one while the sun is shining.. maybe I will cut myself from some 6mm Depron this time..


Hours of fun at such low price..
10 USD 180 watts to 200 watts Motor
12 -15 US Dollar 30 to 40 amp ESC
3 x 10g servos at $2,50 each....
6MM Depron, Biofoam or CORO material and some balsa with a spruce or bamboo wing spar to strengthen the wing.


Vivek made his from Foam board from Ashish in Delhi ;   Images attached...
4MM x 4ft x6ft aprox
Both side laminated bio foam sheet.
Price:RS 3. 72paise +tax per sheet.
Box of 20 sheets.
 
Ashish is based at ; Paharganj, Chuna Mandi, New Delhi.

He has used balsa as doublers for bottom of the fuselage and is yet to cut out holes in the wing, Rudder and Elevons to lose some weight. It will be then covered with Garware film and painted as all his planes.
It can be flown with a small diesel engine or electric.....

His has turned out at nearly 900 grams compared to 450 g in Depron or as mine in 10mm EPP that ended up weighing 580 grams after covering in packaging tape and some re-inforced glassfibre 2inch tape.

The beauty is it uses most 1300 to 2200 mah 3 cell Lipos from your hanger. Just slide them along the fuselage to get C&G correct...

I will post a video one of these days as now we have excellent flying weather in UK.. Last Sunday was superb 24 degrees C and this week has been 21 to 22 too..Winds are 8 to 13mph just the right conditions we long for.. Lets see how long it lasts..

Had some nice flying sessions with the Mako/ Phish as Flying Marcus calls it. Allan made a couple of videos, here is one, need to tell Allan;he must hold the phone vertical or we have a inclined angle video....  The other one is better..will post soon...  Its a pity, my Movie maker programme has stopped working and I cannot edit and make these videos better..  Anwar I need your help!!

Here is Allan posing with his Cap and me with my "Phish" or "Mako"

Here is Allan flying his Cap;http://youtu.be/ISxeqGOrYIo (http://youtu.be/ISxeqGOrYIo)

That is a well tuned aircraft. Smooth flying. Great to watch.

Cheers,

The Mako is a great model  :thumbsup: :thumbsup:

Sanj how about building one in CORO...and see how it flies..

I had an AIRCORE 40 aeroplane model (American) with a removable power pod for IC engine, throttle servo and rx 15 years ago. This allowed the modellor to have one pod for 4 of their planes from Air Core range.

It was advertised as an indestructible model as a man laying the wing down flat on the floor and jumping up and down on it...
For spar it had a hard wood baton 15mm or 20mm thick and approx 50mm wide and the length was a bit shorter than the wing length. It was placed at approx 50mm away from the leading edge and wing folded over and made up very similar to the your Cub...

The strengthener on the vertical fin/ rudder and horizontal stabiliser were hard wood dowels pushed into the flutes of Coro.

So one could use that strengthening technique and instead of a aluminium wing support???? worth considering pushing a few carbon rods or bar B que sticks down 2 or 3 flutes if one can get long enough..  We have also seen guys using 4mm aluminium rods as dowels for rubberbanding wings to fuselages.. So a aluminium rod might be a good idea ..only need one of about 65cms long or even 50 might do.

Interesting project :D

Have to try it soon ;)

My second "Mako" on the build this time from very similar plans of Pete "THE STIG"...
Thanks to Allan for helping.. A through engineer at work and play.. I normally overlook minor details but not when Allan is around....

And some more..;

a few more...;  Rest when model is completed... Cheers...

A bit more on how Mako started coming from Veteran "The Stig" of RCMF;


" Part 1 of my Mako story
 
I guess it was about 10years ago , I was teaching a guy in the trade to fly and also building all his models and he turned up with 2 Makos , one for me and one for himself ,
 
The Makos were for indoor use but he flew his outdoors and was obviously a bit light . He got bored with it and gave it to me so now I had 2 .
 
I still have one which I will photo later , and its got 3x 5 gm servos and flies on a 450Ma lipo, its very light !
 
The problem with the original is that as it intended to fly indoors l  and flying it outdoors puts loads on the wings it was never designed for . The wings would bend , and then if you think about it  the ailerons would not work , ( the hinge line would be a curve !!!!!!)  so the only effective control was the motor followed by the rudder untill things slowed down enough and control was restored .
 
To stop the wings bending I sewed an arrow shaft to the top of the wing, it worked well but looked awful , and so the 6mm winged Mako was born ,where the carbon arrow shaft spar became an intergral part of the wing
 
thats how it all started for me and Makos ,
 
Part 11 will follow when its cool enough to get in the attic and get the original down for photos !!
Cheers...

Just as a bit of interest , well name dropping really .
 Andy who owns OPTIFUEL has one of my Makos , swapped it for damaged 3D plane.Had his in the back of the stall at Weston Park , he told me it goes to all the shows he attends, and flies in the evening.

 It proved so popular with the aerobatic crowd, he ran out of charged batteries.... Pete"

Waiting for part 2... 3... from Pete..

Why so many CAUTIONs?
And only on one side?

Possible Ans:
If you can see the bottom, you'in trouble! Hehe.
 ;D

KK Sahib, that was just copied and pasted from Pete's email... I will ask him for you next time... Hopefully on the flying field on Sunday if its not a wash out here in UK....

@b4ggu
Oops.
Some of my off the cuff cracks sound not so nice in hindsight.
Mae culpa.
you know that was the last thing on my mind

regarding - down and right thrust

what you will do when you have pusher plane ?  my sky surfer always climbs with throttle , i want it straight like an arrow

I'm afraid there's anything you can do, other than trimming as the motor is glued to the motor pod. Else you could have reduced the climb by giving some upthrust to the motor.

Trim will not work ,i mean as you do more throttle , it will climb more ,and the motor is not glued , i am using an aluminum adjustable mount

While on the subject of Mako...here are some images from Pete's loft... Enjoy!!

Some more;

KK Sahib.... Cheers.....     :)   No offence taken as none was meant.. Safe landings is all we wish for now!!

Need help in setting this 3 Axis Gyro as I cannot get it to work properly on the Mako...
The rudder and elevator is working but some how the gyro is not cutting in on ailerons. Allan and I have tried various settings and eventually after spending nearly two hours have given up and will be doing the maiden with below setting..

Any suggestions from fellow RC flyers who have had experience with the Hobby King's V3 Gyro Rxs will be helpful!

Normal Wing selected (Delta unselected)
Setting in Aux1 /Flaps/Gyro gain on tx set to ; 150%

hi,

pls can u send me a pdf plan or dxf file.

will try to get it lasercut on 6mm depron available here.

email plan to sandeepbajare@gmail.com


regds

Hi Sandeep....

I do not have a pdf plan or a dxf file. I had a copy of traced plan loaned to me by a friend and since then, made templates for fellow RC flyers to borrow...

Then again, a friend might be able to help, I will request him.
Cheers...

Deepak

Sorry I need to re-phrase;


The transmitter moves the ailerons and elevator in the correct directions.

The problem actually occurs when we switch the GYRO on.
In which case the Gyro compensation is reversed on the ailerons but the elevators are compensated correctly.

If we change the settings on the gyro to get ailerons to compensate properly, the elevator direction reverses.

Hi all you flyers in India
I was browsing the internet and came across your posts about the Mako.
I fly at Rolls Royce Ansty in England with the original designer of the Mako (Pete Willbourn - Father of Marcus).
It is a great little plane. We all had a Mako get together last weekend and we ended up with 22 of them!
Here is a link to a video I made when we had a Mako Limbo competition. They take a lot of abuse!
http://youtu.be/2LzfXGPzlzw (http://youtu.be/2LzfXGPzlzw)
All the best from England
Ady

Hi Ady,
Delighted to see you on RC India... I have been uploading your video links that Pete has been emailing me.. Now I dont have to do that anymore... instead you can keep us updated on the Mako scene.

Still waiting for fellow modellers in India to upload their Mako images... So far only Vivek has built and flown it in foamboard..... 
Lets hope we can see some Makos flying in India too... Guys you will love this all purpose live in boot of a car plane..

BTW has anyone got this DEVO 7 tx by Walkera? Its quite small ..I am told it binds to frequencies of most popular makes so you do not have to buy any Walkera rxs for it.. Orange or flysky will do..
 

Hi B4ggu
Oh, I didn't know Pete was emailing you the videos. Ha ha that explains a lot  ;D
I'm sure I know who you are now. Are you still a member of Burbage?

The Mako is a great little plane. I always take mine on holiday wherever I go. It's great on the beach. They can take a LOT of punishment as you can see in the video I posted on Sunday. Pete and another member had a mid-air collision and they both just threw them back into the air. Pete even knocked one of the limbo poles over and broke it. He just threw the plane back in the air and kept flying. Great Fun!

They will fly in just about any wind conditions short of a hurricane too. We have had them flying backwards in a strong wind.
I'll post more Mako stuff when I get it.

Happy flying
Ady

Hi Guys
Here's a video showing what the ducted fan Mako can do.
Flown by Alan at Rolls Royce Ansty.
Very enjoyable to watch  {:)}

That's One Good Plane !!!

Aman.:D

Hi Aman
Yes Alan always comes up with good and interesting planes. The "Ducto" is great fun... and loud too.

I've just looked at your City on Google. It looks amazing. India must be a wonderful place to fly.

All the best
Ady

Hi Ady,
Sorry for such a late reply;

Yes I am still a member of BMAC.

I keep my Mako that Mark Kettle cut out of Black EPP in the car and fly at Knighton Park after work on days there is no football.

You are absolutely right, those who have not flown this plane, do not know what they are missing; Mako is a delight to fly in windy condition and in sunny warm days with no wind it is a treat.... I fly mine just about a foot off the ground in very tight circuits...

Its great fun daring touch and goes too and with a prop saver, even if it arrives hard on grass instead of touching there is hardly any damage..

I like that Ducko ... doubt if I will be able to get clearance on that noise...

Do keep posting anything you can on your flying..  All the best and safe landings!!

Deepak

I really like the videos of the Mako flying. It reminds me of my favorite airplane the 3D-Delta by Leadfeather. I have flown my 3D-Delta dozens if not hundreds of times. I want something in a delta about the same size....and I think the Mako will be just what I want.

I am in Florida, USA and use RC Groups of most of my searching for knowledge and plans for RC airplanes. RC India looks like a great resource of information and knowledge! I contacted Deepak and he was kind enough to send me some information......Thank you Deepak!

My Mako is just started and it already looks great to me! What are others using for down thrust and right thrust?

I am going to try to attach a photo of my build hot wire cut and trial fitted.

The second photo shows a moth that I may use for an idea for painting the Mako

Glad to help.

Yes please do keep us posted on your build blog.
Will look really awesome with that Moth paint job. Looking forward to the images and videos.

All the best.

I don't want to cover up this forum with information that is not interesting to others, but I do love to shoot photos of my builds and write about them. So I will add some information if others are interested.

I built a commercial Twisted Hobbies EPP airplane and was impressed by some of the ways they produce their kits. They are also very good flyers! So I am using some of the Twisted Hobbies ideas to build my Mako. Instead of carbon fiber they use thin strips of wood for strength. My Mako has a thin 9mm wide strip of maple for a spar in the wing. Very easy to install, just cut a straight cut through the wing and glue in the wood...no mess!

I use a computer power supply to heat my hot wire equipment as well as other uses. The computer power supply I use outputs 12 volts, 5 volts and 3.3 volts. It is shown in a photo below. I cut a thin poster board of the parts and use push pins to secure it to the EPP sheet that I am cutting. I built a vertical hot wire kind of like a band saw so I can make nice 90 degree cuts in the EPP. It cuts quickly and kind of seals the edge of the foam. I use the 12 volts output of the power supply for this.

Another use for the power supply is to cut "U" shaped channels out of the EPP for hinges. The EPP will bend where it has been thinned out with the "U" cut. I made a small cutter out of a scrap of wood and a length of .020 thick stainless fishing leader wire. I can slide it along a metal ruler and make nice clean cuts for the elevons and rudder. I use the 3.3 volt on the power supply to heat the short length of wire.

I have cut the fuse doublers out of 6mm EPP and glued them to my Mako. There is a photo of it below.

After doing some drawing of the moth design the size of the Mako, I did not like the look of it, so it will have a different design. The next step is to do a little airbrushing.......

Ray

It has been so HOT here that progress has been slow on my Mako build. I am usually a slow builder, but the heat has not helped.

I got some color put on my build. It did not add much weight...maybe less than 1/4 oz. ...my scale is not the best.

Made a design that fit, cut some stencils and airbrushed some neon acrylics on to the EPP. I have used acrylics in the past with little problem, but the neon colors tended to clog my airbrush. Spent more time cleaning than painting. Just taped the bottom with masking tape and shot some black on it. The black and white is easy for me to see, so I usually paint my airplane bottom sides that way.

Ray

The Mako is finally ready for flight! Yes I am probably the slowest builder here!

I got the electronics installed. I used Deepak's photos for placement. It balances right on the CG with no battery. That will allow me to use different batteries for weight or length of flight. I had to cut a lot of foam to get the rudder servo low enough to  not interfere with the aileron.

Is anyone using any reflex on the elevons? Some deltas like reflex.

My Mako weighs:
Just the foam glued together.....3 oz.
Foam, glue and paint................3 1/4 oz.
All electronics installed..............8 oz.
AUW with 1000 3s battery.........11 1/2 oz.

Wish me luck on the maiden :thumbsup: Ray



 

Good luck

Here's a hint for all who have to fit servos into foam:

Wrap some electrical insulation tape around the servo, then glue it in (foam safe or hot glue)

When you remove the servo, take out the tape and your servo is back to pristine condition

Clean built!!

Thank you sanjayrai55 for the hint about the servos. I did use masking tape in the past so I could clean off the servos, but I have become lazy and just hot glue them down.

Thank you rastsaurabh  for the compliment.

I did maiden my Mako yesterday. It does fly but it needs some adjusting. It wanted to fly with the left wing down. This is the side with the battery, so I will cut out a slot to move the battery to the center of the wing.  I also need to increase the throws, I started out with small throws as the elevons looked large to me. Other than that it does seem to fly fine.

Here is a "proof of flight" video. The video is not very exciting as we wanted to be careful until the Mako is better balanced. It looks great in the air to me! I already want to build a larger version of the Mako maybe 150%!!!
