    speedster 200 prop pitch

    quote somefun:

    "it's nice to see the boost and RPM's the same at WOT now. Cruise speed is the unchanged.. I highly recommend change the one impeller to make them equal..It was 3mm out of the starboard side and 1mm in the port for me. "



    should i pitch my 15-20 props +/-right away like this before putting them in becuase of this phenomenon, is it correct that all speedsters will have the same problem right?

    ciao jim

    This might have been caused by inconsistencies in the impellers new. Impellers usually are not perfect from the factory. What I would do is make sure both props are true 15/20's. Then put them in and see what the RPM's are at in each motor. make sure you have an aftermarket rpm guage like a pet-tach to read the rpm's accurately.
