Important Information About Your Brushless ESC
Make sure your ESC brake is programmed to off. Also, be
sure to use an ESC with the proper 9V cutoff when using
3-Cell Li-Po packs. We suggest this cutoff to be of the soft
variety to prevent hard motor cutoffs during low-level 3D
flying.
 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 locknut.
The use of the locknut will prevent the propeller
from coming loose.
Use the 10-tooth pinion we include with this
airplane on the motor.
