IMPORTANT INFORMATION ABOUT YOUR PROPELLER
It is very important to check to be sure the propeller is
balanced before installation. An unbalanced propeller
may strip the gears or cause poor flight characteristics.
 1. Slide the propeller adapter in the hole in the
center of the propeller. The E-flite logo will be
on the side with the threads to be installed in the
correct direction.
 2. Slide the spinner backplate in position over the
threads of the propeller adapter.
 3. Thread the propeller nut on the threads of the
propeller adapter. Only thread the nut on a few
turns, as tightening it now will not allow you to
install the adapter on the motor.
