Instructions
Attach the training gear mounting brackets to the helicopter landing skids. The brackets should snap on the the skid and the strut that connects the skid to the helicopter body.
Pass the rods through the mounting bracket. Attach the rod to the four-way connector included with the training gear. When each rod has been installed, the rods should form an "X."
Attach the ping pong balls to each rod end. Try to center each rod so both sides of the craft are protected. Centering the training gear will also help keep the helicopter balanced.
