E-flite P-47D Thunderbolt 400 ARF - Manual (Page 31)

Note: When installing your motor into the
gearbox, it is very important that your gear
mesh is set correctly and the gear’s mesh is
smooth with no binding. This gearbox features
multiple mounting holes so that you can ensure
your gear mesh is correct depending on the
motor and gear ratio you have chosen to use.
Using the 18mm hole spacing will ensure the
gear mesh can be set correctly when using the
Park 400 motor and 6.5:1 gearing. Remember,
if your mesh is too loose or too tight, it may
strip the gears.
Proper gear mesh is extremely important for
high power setups. Be certain to check the
mesh at multiple points on the spur gear
before finalizing the motor mounting position
in the gearbox. To extend the life of your
gearbox, we also recommend using a small
amount of grease, such as lithium grease, on
the spur gear.
We strongly recommend the use of our E-flite™
Park 400 Inrunner Brushless Motor. All product
testing was conducted with this motor.
