Note : Steps 1 through 4 are for installing a
gearbox and motor, while Steps 5 though 7 are
for installing an Outrunner motor
 1. It may be necessary to attach motor adapters
or other accessories to your particular motor
at this time.
Note: Use the instructions provided with the motor
to install any accessories. Follow the instructions
provided with the gearbox for some helpful hints
for installing the motor. When installing your motor
into the E-flite™ gearbox, it is very important that
the gear mesh is set correctly and is smooth with
no binding. The E-flite gearbox features adjustable
slotted mounting holes to ensure your gear mesh is
correct. Remember if the gear mesh is too loose or
too tight, it may strip the gears. To extend the life
of your gearbox, we also recommend using a small
amount of grease, such as lithium grease, on the
spur gear.
It is also very important to check to be sure the
propeller is balanced before installing onto the
shaft. An unbalanced propeller may strip the gears.
When installing the propeller, please be sure not to
over-tighten the 3mm lock nut. The use of the lock
nut will prevent the propeller from coming loose.
