* Load the spring by rotating the tensioning arm 270° clockwise (when looking down from the top of the helicopter).
*Tension the boom until the tensioning arm is aligned with the frame.
*Tighten the 4 screws.
*Check that the tail output shaft is perpendicular to the tube. ( figure 2 )
*In figure 3,4, 5 you can see the three conditions, ok, too loose and too tight.
