    No one that I'm aware of uses 10% nitro in the States, so disregard any references unless they say they are using that fuel.

    Hi!
    I have tried 8.8x9.00 but using 10% nitro I think that prop size is too big, loads the engine too much. 8.8x9,25 would be even worse.

    I would agree with that Jan, stick with the lighter pitch props, shoot for a peak RPM around 20,000 and back off about 500 and find something that works.
