NOTE:
Once the swashplate is leveled it is important to set
the phasing of the the washout base. This is done by
rotating the rotor head until the flybar is perfectly in
line with the body and the tailboom of the helicopter
(see the diagram next).
The washout driver is now turned to line up the joint
balls on the upper swashplate ring with the center line
of the helicopter (see below) allow a small amount of
clearance between the washout base and the phase
ring when at full pitch. When you are satisfied tighten
the phase ring to the mainshaft with the M3x4 set
screws applying thredlock. Ensure to get this settings
right as it will affect how the helicopter behaves in
hover and when doing acrobatics.
Different adjustments can be done depending on main
blades and their characteristics.
IMPORTANT:
Use threadlock to secure the M3x4 set screws
