Flew mine for the first time last weekend. Has an FPE 2.4. I balanced at rear of recomended CG. Very stable aircraft w/ no bad tendecies. Tracks straight on take off and does slow down fast w/ throttle is chopped. Has nice axial rolls, and tracks well through loops. Rudder has a lot of authority, nice wing overs and stall turns. Knife edge requires very little cross controls. Motor turns a 20x10 prop about 6300 rpm. Plenty of power for normal aerobatics. Dont do 3D. Weighs about 15#. I am quite happy w/ it.
