Important Information About Your Propeller
It is also very important to check to be sure the
propeller is balanced before installing onto the shaft. An
unbalanced propeller may strip the gears or cause poor
flight characteristics.
Note
: If it is necessary to enlarge the hole in the
propeller or the spinner, make sure to check the balance
of each afterwards.
9. Prepare the spinner backplate and propeller as shown
with the propeller adapter.
10. Slide the propeller assembly onto the motor shaft.
With a gap of 3/32-inch (2.5mm) between the spinner
and cowling, tighten the adapter to secure it to the motor
shaft.
11. Attach the spinner cone to the spinner backplate
using two 2mm x 8mm sheet metal screws and a #1
Phillips screwdriver. Make sure the propeller does not
contact the spinner cone when it is installed.
