I am introducing my new fully aerobatic trainer anti stress machine
Which I build in Coro actually this aircraft I build few months ago but do not install
Electronics on it

Here now I have powerful motor to fly this model I am showing you some pictures of the construction of this model also I made some modification in the model

Initial plan done to build airframe

Fuselage construction

modification in the Fuselage

construction of landing gear

the prop i am using is 8" it is very large size so i design lending gear in such a way that when the plane take off run still their will be clearance for the prop , so that it do not touch the ground

i use wheel of the remote racing car which i bought for my kid and few iron rods

installation of elecronics

i use large size rubber band to attach wings landing gear and prop

airplane ready to fly

flying pictures

flying inverted

inverted climb   

i fly this airplane without landing gear also

sun and fun

conclusion of the project

it is a hit machine i call it anti stress machine

i am not expert pilot i can handle this airplane so does i think for other

now i am trying to hover the airplane if got success will share  with you

thanks for all your support .   

Cheers !!!   

@wingmanbunty
Congrats on success.

Single layer wing?
Be careful of wing bending.
See pic 'inverted2' in reply num 8.
Wings bending towards undercarriage.
Lovely photo!

@K K Iyer


today is rainy day i was not able to go for work
i am watching you on line and wait for your reply thanks for showing interest
i use double rods for the strength of the wing yes it is single layer wing

thanks again for kind words

Bravo Bravo bunty.
SO hows the feeling of first getting something up in the air?

Wow! Surprised that flat wings can fly beautifully too! Would love to see the video. Cheers!

#vishal rao surprised to see such flat wing to climb seamlessly..

It is single layer wing ,i want to reduce wait ,but for strength
 it has double rods .

Isn't there too much pitch variations (nose up/down), especially during winds?

Thats the flutter kind of problem comeup with coro structure,i know you doubt about the single layer of wing ,the airplane is very stable  ,no pitch problem

here is the video of coro build anti stress machine

new airfoil design

build from packing thermo col and hot wire cut

idea is to get increase endurance,easy to control and more stable flying result

By experimenting new airfoil build I got some interesting picture which I am sharing with you
(Smoke test)as I call it :- very light adjustment of table fan airflow and smoke of burn sticks
These are rough surface
Flat wing as I use first it in my anti stress machine
And finally the cut view of the airfoil used in anti stress machine to increase endurance and glide performance of the plane

Result
Yesterday morning made test flight
The performance of the wing was superb I enjoy thermal with eagles and return back safely
I also perform loops the smoothness is awesome
I say to eagles “ye kar ke dikhaoo”(do just like me)loooop

 
I suggest anti stress machine is complete from my design point of view wing perform beyond the expectation and really It is going to take all the stress
