To convert from 2 blades to 3 blades you want to decrease the
total blade area and increase the angle of attack (or pitch) to
overcome the increased drag of the third blade.
The general rule is to DECREASE propeller diameter by 1-2”,
and INCREASE by 1-2” the propeller pitch. It is all right to keep
the same pitch when going from 2 blades to 3.
兩葉槳 長度-1 pitch+1 = 三葉槳的size
