OK - I have been reading alot of posts and I've just about decided to get a Hawk sport but I live / fly at 4500 ft so will the OS 32 (BTW - I found one for $50 )have enough power to take me through learning to some 3D? should I get a bigger heli? or will a bigger engine fit the Hawk? I already have an 8 UHP and a 9CAP but am wondering which one to use? also which gyro?
