Nice plane, very stable.. I have a KF2 airfoil depron wing which is 3 feet span. Its weight is 125grms, so its a remarkable job to keep your wing at 115grms. so do you have spar running full 4 feet span? is it a CF rod?

Lets look at this way- wing 115gms, the all up weight is 1.3kg. I would think that this would put quite a stress on the wings.

Anyway, unlike your method, I do share the details of my build regularly (as do most of the other builders) - for example check out my build http://www.rcindia.org/electric-planes/scratch-build-powered-glider/msg83597/#msg83597
The all up weight is 665gm at 50" wing span. Wing construction is detailed as well. No big secret.

BTW, this is flown regularly and has survived quite a few hard touchdowns.....

Yes Mr. Koushik i have used a span but not full length . Its like 75%of the wing span.
I used a glass beat (Commercial name, used for glass work ) its a 1cm*1cm*90cm wooden beat, quite light and very strong.

Good build Mr. PankajC . The reason why my plane is so heavy is that i have used coro sheets 5mm thickness and i had a motor  which had a thrust of 1.7kgs which i wanted to use so made a heavy plane. :-)
