    inverted motors



    Too much wind outside today to really see if there's an improvement, more soon.

    Interesting.
    Have you flipped the props or just reversed the motors? You can loose a third of thrust by having them upside-down.

    One thing i don't like in such a configuration is that it seems that any contact with the ground would result in prop damage, and the motors are in the most vulnerable positions as well.
    Long landing gear is a necessity.

    Would be interesting to know what the upsides would be.

    I've flipped the props and inverted the motor direction, the props are the right way up, with letters up.

    I'm testing to see if there are any upsides.
    i saw a big loss in lift after changing from arducopter arms to towel racks (wider), so I've started experimenting

    This way you can have a super-flat top, I'm not sure why that'd be useful, maybe for those tennis playing quadcopters?

    or, another ridiculous idea, mount wheels to the motors, have the motors point slightly outwards too, then your quadcopter turns into a car when it lands

    I like the testing! Seems to be of some advantage for mounting stuff as said. And that idea about wheels on it...
