BEFORE STARTING

Tools, accessories, etc. The following items
are necessary for operating the engine.
Propellers
The choice of propeller depends on the design
and weight of the aircraft and the type of flying
in which you will be engaged.
Determine the best size and type after
practical experimentation. As a starting point,
refer to the props listed in the accompanying
table. Slightly larger, or even slightly smaller,
props than those shown in the table may be
used, but remember that the propeller noise
will increase, due to higher rpm or if a larger-
diameter/lower-pitched prop is used.

Warning:
Make sure that the propeller is well
balanced. An unbalanced propeller and/or
spinner can cause serious vibration which
may weaken parts of the airframe or affect
the safety of the radio-controlled system.
DO NOT forget the WARNINGS and NOTES
on propeller and spinner safety given on
front pages.
Reminder!
Never touch, or allow any object to come into
contact with, the rotating propeller and do not
crouch over the engine when it is running.
Spinner
Since the 75AX and 95AX is
intended to be started with an
electric starter, the addition of a
spinner assembly for centering the starter
sleeve is desirable. Use a heavy-duty, well
balanced spinner either of metal or plastic.
