Which version are we working on here? The first post looks like the V1, the V3 is a better version with better CoG and I believe I cut the ailerons out a bit from the fuse. In fact, you can cut the ailerons right where they are with the flaps, and not put flaps on the wing.
I will try to do a V4 that has a better wing design as the old KFM is an outdated design now, but is strong with the right foamboard and proper amount of glue. Guess I need to fire up the program again lol.
