Can you describe more about when this happens?

Sometimes this happens when you test the quad without props. You put the throttle up a little to test the motors, then it will try to level itself.  However, with no props, it cant level itself so the motors slowly spin faster and faster to compensate.

IF that is what you are seeing, this is expected behavior and it should fly ok with props.

If not, please describe your problems in more detail so we can try to help.

Hi
Without props motots going to maximum speed with absence of any input (throttle on mimimum)
With props in the air i have same kind of problem - shortly after take off quad begin to fly out of control (just has some crashes). Tried to level it via "librepilot" many times but can't eliminate that issue. And i don't find any problem via system settings.

I would recommend that you either try ESC calibration and motor neutral setting

or start over and make sure you do the ESC and motor settings correctly.  :)

I recommend that you use PWMSync for your ESC protocol, at least until you get it flying...
