I have the 8 bit 3 axis BCG running Hercules BL GB4006 Motors for each axis...

Operation of the yaw and pitch work flawlessly but the pitch axis does not respond to disturbances. The sensor correctly defines and displays deviation from the level setting however there is just no response. The motor gets very hot and feels like it has large steps when you try and force rotation. I have tried PID manipulation, tried changing motors, been through all the settings, tried changing roll and pitch outputs on the board and redefining in the software. Gimbal is brand new and has latest firmware but I cannot get it to work...
