PROPELLER INSTALLATION
IMPORTANT INFORMATION ABOUT YOUR PROPELLER
It is very important to check to be sure the propeller
is balanced after the hole has been enlarged. An
unbalanced propeller may strip the gears or cause
poor flight characteristics.
 A. Use a drill and 3/8-inch (9.5mm) drill bit or
a propeller reamer to enlarge the hole in the
propeller so it will fit on the aluminum spinner.
 B. Slide the propeller on the threaded shaft of
the spinner adapter. Make sure the numbers
embossed on the propeller are facing away from
the spinner backplate.
 C. Slide the washer included with the spinner
assembly on the threaded shaft. The nut included
with the spinner assemble is then threaded on the
shaft. Only thread the nut 2–3 turns: it does not
need to be tightened at this time.
