Pioneer 300
Rotax 912S
AP332F
Whirlwind R68W
Don't seem to have lost any top performance with the extra blade just as you said when I bought the propeller, yet have all the advantages of a three blade propeller.
Fast cruise is 140 knots which is normal.
Extremely happy with the propeller and the Whirlwind blades.
Thank you
Sefton
