Wow i cant figure out why mine flew tail heavy and very touchy on elevator then i had my cg just at 5 and 1/2 inches back from leading edge which is right in the wing tube area. I will let you know how she does today later with it around 5 inches back. I would like to know also where did you mount your servo for rudder in the rear part of fuse, i was thinking of mounting it on bottom of fuse ?? thanks for your reply captaincliffhan.
