Cruise:

To change propeller position from Take—Off to Cruise the RPM must be between 2000 and 2200. Pull
and release the propeller control. A 500 RPM drop should occur without throttle adjustment. The
throttle can then be opened for Cruise power (2500 - 3000 RPM) as required.
In the cruise mode the throttle can be reduced by 1/3 for fuel economy without a noticeable loss of
airspeed.
