    Default Rotax 503.... What thrust do they produce?

    Can anyone tell me what thrust figures they've achieved using a 503 in an integrated craft?

    Any info appreciated!

    Thanks all, and to answer the question... no I'm not about to start using 503's in our craft! Just needed some comparison data for testing purposes!
