    Yes, but his school had 3 in less than a year, on aircraft which were well maintained....
    The three most useless things in aviation:
    • The air above you.
    • The runway behind you.
    • The fuel in the bowser.

    Rule #1: Always tie-down your aircraft to the largest heaviest object available. The planet Earth meets these requirements and is readily available in all locations.
    Rule #2: The great thing about twin engined aircraft is, if one engine fails, the other engine always has just enough power to get you to the scene of the crash.
    Rule #3: You can never have too much fuel in an aircraft. Unless it's on fire.

    912s have never been under the threat of grounding by CASA...

    912s have been turbocharged. Can you imagine a turbocharged Jab? Be a good way of launching engine parts into low earth orbit.

    I'm sure we all have our list or preferences.

    Where would we put:

    Jabiru 4 cylinder
    ULPower 4 cylinder
    Rotax 912

    List 'em in order....

    [Disclaimer: I'm not that fond of Rotax engines because of their price and because of their popularity with thieves!]

    Having flown behind a few Jabi's, I have to say I quite like them. They had issues, but the fixes are now known. MadamBreakneck mentioned that they rev lower than a (four stroke) Rotax, which is true, but I point out that they rev a bit higher than the ideal propeller speed. Rotax solves this with a gearbox. With a Jabiru you tend to need a short propeller which then pushes less air than a longer propeller. Back to my point, given a choice between a two-stroke engine and a Jabiru, i'd go Jabi every time.
