Hello, I have an LT-22B M16A4 from JG/GE that refuses to fire. How I mean is that the motor works until it tries meshing its gear with the connecting gear in the GB. I'm stumped. I have the wires on the appropriate tabs, running through the correct way, and again, it completely works fine outside until it tries moving the GB. 11.1 LiPo. Nothing, looks completely frozen. Any help is much appreciated.
