Propeller Selection
In the chart below you will find a
propeller selection list. This chart will
enable you to select the best propeller
for initial setup of your Saito engine.
Remember, it is imperative to balance
each propeller prior to installation
onto your Saito engine. Failure to do
so may cause unwanted vibration in
your aircraft.

NOTE: Observe operating rpm ranges as excessive rpm can result in damage to the engine.
You will note a letter (A, B,C, etc.) stamped on the top of the motor mount. This letter
identifies the production version of your engine. Should you ever need to order a part or have a
question pertaining to your engine, specify this letter along with the engine type. This will
allow for easier identification of your engine.
