Hi Captain,

Mine isn't difficult to fly, it is just that if you haul back too hard on the elevator, it will snap on you. It has a souped up Homelite 30cc in it. (APC 16x8 at 9400 rpms.) It weighs 13 lbs., and I didn't have to add any ballast anywhere to get it to balance at the recommended c.g. The wing loading works out to 31 oz. per square foot, which is a touch high for this size bird.

I have attached a file that I used for the control throws.
