Remove the engine and drill a 5/32” hole at

the location you marked. This is the size of

the shoulder of the blind nut not the screw.

Seat the blind nuts using one of the bolts and

flat washers to pull each blind nut into the

bottom of the mount.

Position the engine in the mounts making

sure to leave clearance for the spinner back

plate on front. Mark the location of each hole.

Re-install the engine and bolt in place using

the four bolts and washers. Be sure to use

lock tite on the bolts.

PROPELLER & SPINNER INSTALLATION

The propeller size must be matched to the engine.

For example, a .60 may use a 11" diameter prop

while a .80 four stroke can use a13" prop. Follow the

engine manufacturer’s recommendation for correct

propeller sizes or speak to a knowledgeable dealer.

It's wise to buy a few spare props, as everyone

breaks them occasionally, and particularly often

when learning to fly.
Balancing your propeller helps to protect your radio

from the damaging effects of vibration. There are

good, easy to use prop balancers on the market. We

recommend sanding the heavy blade on the curved

face, out near the tip, rather than on the flat face. Try

to maintain the normal airfoil curvature. Avoid

scratches which may cause the prop to break. Never

carve or cut a prop near the hub for any reason

(such as to fit a spinner).

It is equally important to use a correctly sized spin-

ner. The CGP 4-pin spinner (3-1/2”) for the Heritage

Series Skylane 62 ARF is a rugged precision-mold-

ed spinner which does not require any special

mounting nuts or screws. CAREFULLY READ THE

SPINNER INSTRUCTIONS AND WARNINGS

INCLUDED WITH THE SPINNER. And remember,

although a spinner helps reduce the chance of injury

from a rotating prop, extreme caution always must

be used when the engine is running.
