After my almost successful scratch build glider "DREAMER" -----> http://www.rcindia.org/electric-planes/beginner-plane-%27dreamer%27-1-5-meter-coro-glider/ which was traction so as you all know it, motor always gets screwed after 5 to 6 so called good flights I learnt how to handle the planes and moved to make a pusher plane.
After getting lot of suggestions I planed to make this.Thanks for everyone who helped to do it.  :hatsoff:
Here is the the progress and i will maiden once I finish it.
after a lot of thinking I named it "VAAYU" to have an INDIAN name is better than funky names(for me!).

Here is the build log:

just to say my electronic components are same as the above plane since am not buying anything for now.

wing construction:
Wing is made of 5mm laminated depron
airfoil: kfm2 reinforced with 4mm cf rod and depron of 1inch width throughout the step to get
chord length: 8inch
since the cf rod was 1mtr in length and I dint want to cut it,I made the center wing of 1mtr in length.
the polyhedral is 8.5 inch.


any suggestionsin anyway can help!
will keep posted

thank you

wing taped completely.
used a 12mm beading for twin booms of length 21inches.
I used zip ties for mounting the boom to the wing since its easier to attach and detach during transportation.

Maiden wasnt gud people!
the AUW was 935gms!
I had only quad prop so i couldn't fly it.
some or the other way i need to reduce the weight.
I have SF prop 10x7 which is nt recommended fr the motor but ill try tmrw and test it.

I also tested the another wing which was lesser wingspan and tried to fly it, but wasn't successful.
