Installation of Pinion Gear & Gearbox:
For your convenience, this motor includes both a 10 Tooth and a 12 Tooth pinion gear. It will be necessary for you to install the pinion on the shaft. In some E-flite airplanes,
a pinion gear is also included with the included gearbox. E-flite recommends you use the pinion gear included with your gearbox for the best set-up.
The 10 Tooth pinion is for use with an E-flite (EFLM221) or GWS ‘D’ gearbox with 6.6:1 gear ratios. A gearbox with a 6.6:1 ratio has a 66 Tooth spur gear on the gearbox and
the motor uses a 10 Tooth pinion gear installed on the shaft. The 12 Tooth pinion is for use with an E-flite (EFLM216) or GWS ‘C’ gearbox with 5.33:1 gear ratios. A gearbox
with a 5.33:1 ratio has a 64 Tooth spur gear on the gearbox and the motor uses a 12 Tooth pinion gear installed on the shaft. The E-flite spur gears are a .4 module.
When installing motors into the E-flite gearbox, it is very important that your gear mesh is correct and the gear’s mesh is smooth with no binding. The E-flite gearbox features
adjustable slotted mounting holes so that you can ensure your gear mesh is correct. Remember, if your mesh is too loose or too tight, it may strip the gears. One suggestion
may be to insert the polybag included with the motor or a small piece of paper in between the pinion and spur gear as you are installing them. Tighten and secure the screws
to the gearbox. Always make sure the screws are long enough so they have properly seated into the motor. You can easily pull the polybag or paper out by rotating the shaft
until it comes out. 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.
Once a pinion is installed on the shaft, it will be necessary to remove the pinion from the motor shaft if you want to use the motor with a different gearbox than the ones
specified above. The gear mesh will bind and the motor will not operate properly if you have incorrect gear ratios. We recommend using a gear puller for this step for the
safest removal of the pinion gear. Never reuse a pinion gear that has been removed from a shaft.
