a spinner backplate spacer. If you are using
a rubber spinner, you will slide it on after the
propeller has been secured.
Note: Two spacers have been provided that
are placed between the propeller and spinner
backplate. Use the thin spacer for low-pitch
propellers, the thick spacer for high-pitch
propellers. This will prevent the blades of the
propeller from contacting the spinner backplate.
 7. Slide the spinner backplate onto the gearbox
shaft. Secure the propeller and spinner backplate
using the supplied 3mm washer and 3mm
locknut. Make sure not to over-tighten the
3mm locknut.
Note: It is very important that you check to be
sure the propeller is balanced before installing
onto the shaft. An unbalanced propeller may
strip the gear. When installing the propeller,
please do not over-tighten the 3mm locknut.
The use of the locknut will prevent the propeller
from coming loose.
