 *Wing is 1m span, 7in chord(sorry about the change in units)
*Airfoil is a 50% KFm 2. LE is a 1/2 inch wide,half-round hard wood beading with a balsa spar at 1/3 chord.
* Fuselage is 30in long. made out of salvaged compressed t-col. Made cutouts for all gear. The fuse is laminated with coro sheets.

* Tail surfaces are 6mm biofoam.

'AUW' = 455 g (before gluing, tapeing etc)

Just the plane - 212g
All electronics/gear etc - 236g
(2812-1524kv motor, 4x9g servos, 18A ESC, 1350 mAh, Rx,)

Y-cable, push rods extra.

with most of the taping done, weighs around 480g. Feels tail heavy. May have to push Rx/Servos a little forward to avoid adding nose weight, if at all :-\.

.....intend to keep the WL just under 10 so that its fast enough to give me a feel of a full blown 4 ch experience. Glide tests are flat.

The wing is without a dihedral.

will post when done.....

Very nice Progress.. Frnd, i am a little bit worried about the wing, as the wing seems to have a level drop. Or are you going to sand it later?
I can take off and fly well. Its landing which sucks :banghead::banghead:

Abhay.......I was equally surprised when I discovered KFm airfoils (guess that's what you are referring to?)

...but they work like magic  ;) you should try it.
