That is some good info to have, I have never used expo before even though the radio has it. The other models I have don't need it. Man this thing is diferent than any model I have had. I think it would fly just by flapping the rudder back and forth the rudder is so big. I appretiate the advis, a guy would not want to wreck this plane. I have the Realflight sim and have been flying the Cap on there. Does anyone know if the sim is close to what the real model is like?
