Note: Never check the motor rotation on the bench
with the propeller installed. The plane could move and
cause serious injury. Always check the motor without the
propeller to avoid injury.
Important Information About Your Propeller
It is very important to check to be sure the propeller is
balanced before installing on the propeller shaft. An
unbalanced propeller may damage the motor, airframe
and other components, or cause poor flight and
performance characteristics.
Note: If it is necessary to enlarge the hole in the
propeller, make sure to check the balance of the
propeller afterwards.
  7. Install the propeller and spinner backplate as
shown using the adapter included with the motor.
The spinner backplate will actually be installed in
front of the propeller, and it will be necessary to use
a drill bit or reamer to enlarge the hole in the prop
and spinner backplate so they will fit the prop adapter
shaft. Also, you will need to install the thick washer
included in the kit between the spinner backplate and
prop adapter nut so that the nut can seat properly on
the backplate when secured.
Note: Pay close attention to the orientation of the
propellers as shown in the photos.
