Note 1:

When you tighten the collar (H0121-S) on the main 

shaft, ensure there is no axial play.

Push down the main shaft while pulling up the

locking collar. Tighten the screw M4x22 at this time.

Note 2:

The pinion and gear are designed to have zero 

backlash. This leads to initial “rough” rotation. 

After some run in flights (3-5 flights) it will begin to 

rotate freely, ensuring perfect contact and the 

ability to transmit maximum power.

It is very important to lubricate these two

elements with a lubricant

( Dry Fluids Gear or similar).
