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
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.
Sport
13x9-10, 14x6-8, 15x6
It is suggested to use propellers which develop
maximum r.p.m. of 8,500~9,500 so that you
may enjoy pleasant exhaust sound keeping it
low.

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
after practical
front pages.
Reminder!
Spinner
Since the 75AX-BE is intended to
be started with an electric starter,
the
assembly for centering the starter sleeve is
desirable. Use a heavy-duty, well balanced
spinner either of metal or plastic.
