7. Place the propeller on top of the backplate so

that it lines up with the pin, as shown above.

Place a large washer on top of the prop and

then install, using a #4 x 1/2” machine screw.

CAUTION: DO NOT OVER-TIGHTEN, as this

may cause the threads to strip out.

8. Align the spinner cone with the prop/backplate

and press pins firmly into the holes. One way
to do this is to have the cone pointing down-

ward on a table and press until all pins are

seated.

Install the prop/spinner assembly on the motor

shaft and securely tighten the set screw with a

.050 Allen wrench.

9. Align the cowl behind the spinner/backplate

assembly, allowing about 1/8” clearance.

Holding the cowl in this position, install #2 x

3/8” sheet metal screws at the cowl mounting

holes.

When finished, remove screws and apply a few

drops of Super Jet™ to “harden” the threaded

wood holes. Open the holes with a pin before

the glue dries.

WARNING: A SPINNING PROPELLER CAN CAUSE

INJURY. WEAR SAFETY GLASSES AND OPERATE

AWAY FROM SPECTATORS.

DO NOT OVERTIGHTEN
