I have a raptor and a ergo 30 that I have been using to teach myself to fly. They both seem to fly great, though the Ergo 30 seems to be more stable in a hover. I am told this is due to the Ergo being a hevier heli. The raptor is cheaper to repair though. Only thing I spend my money on was fuel and most important a simulator, oh and Rays Helicopter book since I needed all the help I could get setting the things up. Great book in my opininon.
Good luck
Matt
