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.
