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).
