Quadcopter flips over when taking off.

Posted by Splunkmeister . on March 6, 2014 at 7:40am
I just finished building my first quadcopter, sadly, it's not been able to fly yet. The quadcopter flips over when trying to lift off the ground. The propellers are correctly positioned and are rotating in the right direction. What am I missing?Here is a link to my YouTube video showing the problem. Thanks for your help. http://youtu.be/nF9bGrjR9Uc

    Hi,

    I had the same problem

    I don't understand "i switched the position for motor 2 and  4"

    Could you please explain?

    Thanks

    Thanks guys. The problem was with my motor positioning, i switched the position for motor 2 and  4.

    Seeing your video, it looks as though the accelerometer is set incorrectly, as Joe said, or you have a bad gyro.  I had a similar experience with one of my copters and it was due to a faulty gyro.  It could also be interference if your FC or sensor board is too close to the power source.  Can you plug your FC into your computer and see if it is behaving correctly both when the copter is unpowered as well as when it is powered from the battery?

    Have you calibrated your accelerometer through mission planner? Any weird trim on your transmitter?
