Make sure mast collar is tightened
securely onto the mast. Double-check

properly seated onto the mast and
main shaft can not move up or down.
At this point you will notice that the belt twists 90 degrees as it runs trough the tail
boom. Care must be taken to assure that the belt is twisted in the correct direction. The

and twist the belt in the other direction.
