Just picked up a new Blade CP+ from the LHS. Drove 90 miles back to home, opened it up and started reading the manual and following it step by step. Charged the battery, disconnected the tail rotor motor and main motor. When the battery was charged, installed it and pluged it into the 4 & 1. Working the collective only one main blade increases in pitch. I have looked over everything and cannot figure out what is going on. Any input would be greatly appreciated.
