MAIN ROTOR BLADE ATTACHMENT
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, 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.

Main Rotor Blades
Drinking Glass (2)
Firmly secure the main rotor blades to the rotor head
as shown above. 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.
