Web6 mei 2024 · Propeller Pitch. The propeller pitch exerts a strong influence on speed and torque and, thus, on the choice of engine and transmission. For the efficiency of the propeller, a higher pitch is generally preferred. This is because propellers with a high pitch are usually operated at low rotational speeds to produce the required thrust. http://www.epi-eng.com/propeller_technology/selecting_a_propeller.htm
