Firmly secure the main rotor blades to the rotor head as
shown above. Be certain to note the proper direction of
the rotor blades when assembling (clockwise rotation).
Main blades should be tightened so they can pivot when
moderate pressure is applied. Do not allow the main
blades to swing freely within the main blade holders.
Spanwise C.G. Balancing
Place each rotor blade on a sharp edge of a table as
shown and adjust so each rotor blade “teeters” on the
edge of the table. If the blades are correctly balanced, they
should be at an equal distance to the edge of the table. If
they are not, apply tape to the center of the light or short
blade until equal distance can be achieved.
Final Static Balancing
To static balance the main rotor blades, it is suggested to either
attach each blade to a “seesaw” type blade balancer (RVO1001), or
bolt each of the two blades together through the blade mounting
holes shown and suspend this unit between two drinking glasses.
Add blade tracking tape (from decal sheet) to the tip of the light or
high blade until they each become level to the table surface.
