8. Install the spinner backplate, propeller, propeller
washer and propeller nut to the engine. Align the propeller
with the marks on the spinner backplate and then tighten
the propeller nut securely.

9. Fit the spinner cone to the back plate. Then, use a
Phillips screwdriver to tighten the spinner screws snugly, but
not over-tight.
Selecting the correct propeller for an
airplane is very important. Your
NexSTAR ARF comes equipped with
a specially-designed nylon 11x5
propeller (HCAA3744) with painted
tips. The painted tips are a safety
feature that will help you see the
propeller arc as the engine is running.
Propeller (HCAA3744)
Keep away from the propeller while the engine is running.
The engine size used on the NexSTAR ARF is powerful
enough to cause damage if anything (including you) gets in
the propeller arc. The propeller is made out of flexible nylon
so that it won’t break on light contact with the runway or
weeds. If the propeller ever gets in contact with anything
while the engine is running, inspect it before running it
again. Check for cracks, scuffled tips or unbalanced blades.
If necessary, replace the propeller. The Hobbico NexSTAR
ARF was designed around an 11x5 propeller for best
performance. The 11x5 propeller helps keep the airplane
speed down at full throttle; it increases takeoff performance
on any surface, including tall grass; and it acts as a brake
when the nose is pointed down. Should you ever need to
replace the propeller, replace it with the same or similar
11x5 propeller. There is no benefit to using a larger propeller
or one with more pitch.
Carefully balance your propeller and spare propellers
before you fly. An unbalanced prop can be the single most
significant cause of vibration that can damage your model.
We use a Top Flite Precision Magnetic Prop Balancer
™
(TOPQ5700) in the workshop and keep a Great Planes
Fingertip Prop Balancer (GPMQ5000) in our flight box.
Your engine is now installed.

4mm nuts, four 4mm washers and four 4mm lock washers.
