 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 Undecided.

.....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?

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

 ...but they work like magic  Wink you should try it.
