NOTE
: Have your tachometer calibrated by
a professional before performing this next
operation.
1.
With the brakes on, run the engine at full
throttle and note the static RPM on the
tachometer.
The static RPM at full throttle should
be 2400 to 2600 RPM. MAX RPM at full
throttle during straight and level flight
should be 3100 RPM.

WARNING
:
NEVER EXCEED THE MAXIMUM
RPM RATING FOR YOUR ENGINE. If you
are not seeing your correct static RPM,
be certain the tachometer was properly
calibrated.
2.
After the desired static RPM is achieved,
re-check all bolt torque values (The ideal
pitch setting will allow the propeller to
reach (with out exceeding) maximum RPM
at full throttle in level flight.)
