 4. Slide the propeller on the adapter. It may be
necessary to enlarge the hole in the propeller using
a tapered reamer if it does not fit on the propeller
adapter.
It is always a good idea to balance your propeller.
An unbalanced propeller can cause vibrations
to be transmitted into the airframe which could
damage the airframe or other components as well
as produce unwanted flight characteristics.
 5. Use a hex wrench or ball driver to tighten the
propeller adapter nut. The propeller should be
positioned so it almost touches the small bumps on
the spinner backplate.
Before tightening the spinner nut, make sure
there is a gap between the backplate and cowl
so they do not rub when the motor is running.
 6. Check the fit of the spinner cone on the
backplate. There should be an equal gap between
the propeller and the opening for the propeller in
the spinner backplate. If there is not, go back to
Step 5 and reposition the propeller in relationship
to the spinner backplate.
 7. Use a #1 Phillips screwdriver and two 3mm x
12mm self-tapping screws to secure the spinner
cone to the spinner backplate.
 8. Use two hook and loop straps to secure the
battery in the fuselage. Use hook and look tape
between the battery and battery tray to keep it
from sliding during flight.
Use the battery to correctly balance your model. It
can be moved forward or rearward as necessary
to make changes to the balance of your model.
