TAIL BELT TENSION
To provide the correct tail belt tension, you can use the "zig-zag" method.
Figure 1 , Loosen the 2 RED screws and the BLUE and push the tail side plate in according with red arrow. Tighten the BLUE screw while you are pushing.
Figure 2 , Loosen the 2 RED screws and the YELLOW and push the tail side plate in according with red arrow. Tighten the YELLOW screw while you are pushing.
You can proceed step by step until the tail belt is tight enough.
Hard 3D style will require more tension; Sport flight style less.
When you set your perfect tension, you can tighten all screws making sure the tail shaft is perfectly straight.
( Figure 3 , tail output shaft must be perpendicular with the boom).
