Main Rotor Blade Spacers
.........2 pc
4x35mm Socket Head Bolt
Firmly secure the Main Rotor Blades to
the Rotor Head as shown above. Be
sure 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.
Note: The above items can be found
attached to the Main Rotor
Blade package. Please disregard
the 5x35mm bolts and 5mm nuts
included with this kit.
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.
