    For some reason when I'm trying to take off, my octo wants to tip to one side. I can't even lift without it fully tipping over and digging two props into the ground.

    I've balanced the MoVi M10 gimbal, and seems to be no issue there. Nor are the feet sticking in the ground.

    Has anyone had this issue and is there a solution?

    Thanks
    Damien

    I suggest checking that all your props are on the correct motors and that each motor is rotating the correct way.

    Also this May or may not be obvious however you need to take off with some momentum, otherwise it will want to tip. You should get it light in its feet then give it enough throttle to take off quickly.

    I'd run some more tests with something way less precious than your MōVI on board, too.

    Recalibrate the ACC. Level the flight control board perfectly flat and recalibrate. Should fix it.

    Damien: When you said "it's as if the motors aren't responding to the power" do you mean that as you operate the throttle, you hear the motors spin up faster, but then they hit a maximum and don't go any further? If so, can you confirm that you have also calibrated the compass, please?

    Andy.

    Thanks Sam and Steve.

    Its definitely different now than all the previous take offs. I'm not doing anything different with the throttle amount, but no matter what it doesn't seem to lift on one side. Its as if the motors aren't responding to the power.

    Also as it was said about please make sure the props are installed correctly (Odd motor props on odd motors, even props on even motors) and make sure they are spinning correctly.

    Ok, so it was as simple as not checking one motor. The one that was actually spinning the wrong way :(

    The reason it was, is because the 3 plugged lead underneath was back to front, therefore spinning the motor 180 degrees. Simples.

    Thanks everyone for the feedback. And especially to Holger who sorted it in seconds.
