    Any body know what kind of prop setup you might want to run with this engine. Pitch, length and type? Just fantasizing I guess. Jim

    It would almost be pointless to have this engine without a constant speed prop. Rumour has it that it has to be hydraulic so that rules out airmaster and pretty much only leaves GT/MT propellers

    Just wondering if the prop and hub would come straight from rotax or other combinations would work since it is automatic with the 915is

    I'd like to know whose hydraulic constant speed prop falls into the the MMOI requirements laid out by Rotax for the gearbox. Or did they strengthen the gearbox to handle a higher inertia?

    I believe the Whirlwind CS meets it.

    MT makes hydraulic propellers for Rotax engines, installed on Diamond da-20 aircraft.
