Misha034,

The cg was at 135mm for the maiden. At that cg my plane was tail heavy. Ran out of down trim and flew at reduced power, but was able to land. Moved cg forward to 120mm and that works for me. Still have about about 5mm down deflection of elevator at trailing edge when trimmed, but flys good. As RC warbirds go, this Zero is about the best flying I have seen. Stalls, dirty or clean are fairly gentile and straight with little wing drop, landing speed is fairly slow, the flaps keep it from floating.
