In order to check the belt installation, we
recommend to follow two simple steps:
1- Check with light, look inside the boom
from the tail case and check the belt is
only twisted 90 degrees.
2- Rotate the main gear in the flight direction
(as shown) and check the tail hub rotates
in the direction shown. If the Tail Rotor rotates
in the wrong direction, go back to previous
instructions and double check your assembly.
