How difficult is the intitial setup (assembly and rigging) of the ARF T-Rex 450 SA ? I have no experience rigging rc helicopters, and I'll be using Spektrum DX6 radio gear and servos, Align gyro, and LiPo battery. The brushless motor and ESC should be included with the aircraft. Other than experience, what else do I need to get the setup reasonably correct for my first flights ? The manual for this heli seems really high quality in its detailed instructions. Also, where can I get training gear for this bird ?
