RE: tail rotor misbehaving
i thought that too, but i don't think it would make sense that the RC operator would have to keep the rudder to the right all the time.
just out of curiosity, are you flying yours at the moment like that? I'm still working my way through RADD's step by step guide. Haven't really gotten it off the ground really. Just taking the weight off the skids.
I haven't email Heli-Max yet - i think i'll do so this evening.
