3 bladed propeller will increase your speed and climb.
The SynchroPulse propeller was designed
specifically for the 250, 260 and 260B Comanche and the Comanche GTO airplanes has been
designed to optimize the airplanes performance. In the GTO the propeller raises the
engines critical altitude by providing a little bit of supercharging and provides an
increase in the cruise speed of 3 MPH. The SynchroPulse propeller has a curved leading
edge, a swept back tip and a flap just outboard of the spinner. The flap forces a pulse of
air into the induction system inlet, with pulses arriving at each cylinder while the
intake valves are open. The static thrust is increased 15% yielding snappy acceleration
and better take off and climb performance.
