I have one (my second, as the first one found the fence at the end of our field on a downwind deadstick landing) with an O.S. 91FX. Came out nose heavy. Needed 2.5oz lead in the tail section of the fuz to correct. CG is at the rearmost position mentioned in The Book. Prophangs at half throttle on a 16 x 6 prop. Lands REAL slow. Weight about 6.25lbs. Nicad (1700mAh) mounted at rear of cockpit section to help with less lead for CG. REALLY flat spins!! Prophangs OK. Harriers are "fun" as it's difficult to stop it flying.
