Mount the Motor

1. Without using any tools, use your fingers to press the

motor all the way into the gearbox. Spin the shaft on the

gearbox. If the shaft does not spin freely, back the motor out

just enough to allow the shaft to spin freely. Use a fine-point

felt-tip pen to mark the end of the gearbox onto the motor so

you will know how far to reinstall the motor after the pinion

gear has been fitted.

2. Remove the motor from the gearbox.

3. Use denatured alcohol or other solvent to clean the

motor shaft. Roughen the shaft with medium-grit sandpaper

so the included gear cement will adhere.

4. Test fit the pinion gear onto the motor shaft to see

which way it goes on easiest. The hole in the pinion gear is

tapered slightly and the "easy way" is the way the gear is to

be permanently installed.

5. Remove the pinion gear from the motor. Add a small

drop of gear cement to the hole in the end of the gear that

goes on the shaft. Install the gear until the end is even with the

end of the shaft. Allow the cement to harden for a few minutes.

6. Use a toothpick to apply a small dab of lubricating oil

to both ends of the motor shaft where it exits the motor. Do

not apply oil directly from the container because you may

apply too much.

7. Reinstall the motor into the gearbox up to the line. Fit the

prop adapter to the gearbox. Mount the prop to the adapter

using the appropriate spacer ring and the prop washer and

prop nut. Tighten the prop nut with an 8mm wrench. If

necessary, protecting the drive washer with a cloth, use pliers

to hold the drive washer while tightening the nut.

8. Spin the propeller by hand. The magnets in the motor

should provide slight resistance. If more resistance can be

felt than just the motor, back the motor out of the gearbox

slightly until the propeller turns as it should.
