    have a serious question in your mind! But I have no interest what so ever in discussing Rotax
    593 crankshaft breakage or High Cycle Fatigue of Rotax 593 Crankshafts with anyone.

    You need to go find someone who owns a Rotax 593 engine and wants to discuss this issue
    with you. Because I don't care, I own 10 Rotax 494 engine and 2 Rotax 493 engines I don’t
    have crankshaft breakage problem!

    Scott.
    Scott the only problem with your thoughts on this is that the 593 engine as used in the F500 class is the defacto performance target for F500. With the current min weights for the 494 and the 593, the 494 would need about 110 hp and imo that is not possible under the current rules.

    Default Defaco Standard

    How many times do we have to go through this? There is NO STANDARD in the F500 class DeFaco or otherwise!!! The only standard that exists is in someones head! People just don't get it!

    However they have been ignoring that metric in F500 for years.

    How many folks are actively campaigning that engine package?
    I'm still writing a reply, I'll have a reply latter today!

    2 questions.

    What is the problem?

    Then why can't the 494 engines compete?
