The stock 430l motor is good if you buy it with the kit. The ESC is Ok, but it will do for a while. Go with a 401 gyro, hs 65 servos because they fit and the arms line up perfectly. Futaba 9650 digital on the tail. If I read your post correctly, you are buying a Transmitter too. I would go with the futaba 9C. It has some really nice heli features, and you can see the throttle and pitch curves. This really helps you to understand what is going on. If you have been flying a blade CP, then you will have no problem flying the TREX. You are going to love the Trex if you have been flying a blade. TREX is a million times better IMO.
