After approximately 10/20 flights, please check preload, you can
add one 0.2mm shim (HC232) on each side if preload has changed.
However, we suggest to replace the o-rings after about 100 flights.

It is a normal ( especially with the 90° + 90° O-ring set-up ) to feel tight after initial assembly
as the axial preload is usually high when the helicopter is brand new.
The preload will loosen up after 5-10 flights allowing the system to become smooth.
