With a 12v battery in hand we were now able to get the Main Gear Actuator to move in an attempt to hook up the linkage. What became quickly apparent was that there was a conflict between the housing of the Actuator, Electric Gear and the Main Gear Leg. Hmmmm... what to do? Cut the internal end of the Main Gear Leg back? May 25 update: the actuators have been installed upside down from the outset!
