    Default Twin CAT prop rotation

    Hi guys

    I?m building a couple of twin cats for running on a small lake, can I run the props in the same rotation or do I need to run counter rotating?

    Cheers

    I'm still somewhat new to FE, but I'm guessing it's safe to say, counter-rotating.

    If the props are close enough together they can rotate same direction. I am building a twin cat now that has motors on top of tunnel and only 2.5" apart and I can run props the same direction. If you are doing a twin cat with motors in the sponsons then counter rotating is best.

    Small lake, counter rotation and have them spin outwards.
