Friends please help me

how to fix cloth hinges to ailerons and wing.
If possible post a video.

santhosh-r · December 29, 2012, 08:56:13 AM

Cut out wing section.
The length was not enough to cover the wing and I had to cut the glued rib from coro

santhosh-r · December 29, 2012, 08:58:01 AM

Once again started cutting a new wing .Thank god I had just the required size coro for the wing as leftover.
Wing complete withour ailerons.

santhosh hope we can see the maiden soon.. good looking trainer man..

One thing I don't understand: why don't you make your hinged surfaces in the normal Spad way? i.e. by cutting the flute on 1 side. One of the main benefits of Spads is the time and hassle saving on hingeing

That said, the model looks good; waiting for the flight report

santhosh-r · December 29, 2012, 06:51:53 PM

The reason I didn't use hinges in aileron as used in all SPAD is that I wanted the ailerons to more free to control.

sanjayrai55 · December 30, 2012, 07:07:59 PM

The technique for that is

(a) Cut one side flute fully
(b) If you still have sticky controls (which does not happen with me even with 4 mm Corro) then after every 2" cut a 1" solt

Happy New Year friends....

Let this year be a crash free year....

sanjayrai55 · January 01, 2013, 09:15:20 AM

Same to you Santosh!

Mjet · January 04, 2013, 09:43:35 PM

very good build , we can also build the wings by using wood spur only ( no ribs). how did you cut the ribs from 3 mm ply ?

santhosh-r · January 04, 2013, 11:33:17 PM

To cut the ribs I went to a local Switch board cutter , I drew the things I want to cut on a 3 feet x 1feet 3mm plywood and paid him Rs.150
I got them..But you cannot get it very accurate and straight...
BTW I did not use any balsa on this plane .

Made the first flight....a beautiful stall and then a crash...
The Lipo burst into flames and damaged the motor , ESC and the ESC compartment....

santhosh-r · January 06, 2013, 10:24:28 PM

damaged plane..

VC · January 06, 2013, 11:38:38 PM

My condolences. May she recover and take to the skies again. All the best.

arun.sreelakam · January 07, 2013, 07:15:04 AM

ohh that was really bad...

santhosh what happend actually...? short circuit?

santhosh-r · January 07, 2013, 05:38:02 PM

The model was hand launched , flew very well and made a stall and could not recover and nose dived.
since the screws used to fix the motor was protruding from the firewall the battery hit the screws and went into flames....

Rc Maker · January 07, 2013, 06:07:29 PM

santhosh next time i will fly your model
dont worry we will do it

sanjayrai55 · February 04, 2013, 09:48:57 AM

Great build job Santosh. Very innovative and very strong. Looking forward to the flight video.
