The plane is touchy with full elevator throws(37mm each direction) It will snap over when flying slow, and throwing a lot of elevator, this is the downside of the design that gives it the awesome spins and snap rolls. I added a flat carbon spar to the elevator(H-stab already has a spar in it), and 2 small peices slipped under each side of the plastic elevator joiner peice glued in that extend to the trailing edge, this takes a lot of the flex out of the elevator, and if anything, mine will roll to the left at slow speeds, this is normal due to motor torque, not right as most report with this plane. The CG does have an effect on stalling, it tends to stall at a higher speed, but much more gradually and forgiving with a nose heavy CG, with a neutral CG, it stalls a little slower, but more abuptly. I also have a gyro setup with low gain on the aileron channel, it keeps the wings locked into whatever orientation I want, it helps in the wind, and makes landings and takeoffs very easy. It is not turned up enough to really affect stalls, but does seem to cut down on some wing rock with harriers. In larger loops, the plane tracks perfectly straight, tight loops take a little right rudder which is normal to counteract torque, flips and the Extra's crappy version of a waterfall are not terribly crooked, a touch of right rudder, and moderate right aileron keep the wings level, maybe a bit more throw, but the same inputs that most every decent 3D plane I have flown require.
