Roll on lift off.

Posted by Julie Macfarlane on July 28, 2011 at 3:01pm

I have the quad sitting next to the computer, props off.

If I connect the battery and then the USB, then connect into the MegaPlanner.

Switch in flight mode.

If I arm the motors (low left) the green led stops blinking. Throttle up spins up the motors, but the artifical horizon rotates up to 45%.

If I reduce the spin, the AH gauge levels off. The faster I spin up the motors, the faster the AH rolls.

 

Any idea what to check for?

    I tried flying it last weekend and it did the roll thing on lifting.
    Returning home, I erased and reset everything, then noticed the error when testing.

    I'll load props tonight and try your suggestion.
    Thanks!

    Have you tried hand test without APM-MP ??

     

    Put props on, take firm grip from dome center and start your engines. Keep quad as far as you can so you are not get hit by props and then just give throttle till you feel lift from those. How does it feel when doing this?

    I thought it might be an electrical connection to power, but as long as the motors are spinning then the roll factor is present.

    If the motors are armed and not moving, the craft sends data appropriate to its position, as I hold it and roll it around.

     

    Throttle up and the craft shows the increasing roll condition. It makes the craft unflyable.

    Anybody ever seen this happen before?
