yaw problem

Posted by Max Xam on July 25, 2011 at 10:09am

Today i installed 2.37 on my quadcopter. First impression WOW!!! Alt holt is impressing..

 

But after some flying the quadcopter suddenly turn(yaw) 90 deg (in simple mode) and i was not able to steer because he was now and then turning 90 deg, always counter clockwise... Made a quick landing without broken parts...that was the good part..a few months ago i lost a quadcopter..

 

i have no compass..

 

Some advise for me?

 

Thanks,

Max

    I guess its because of the compass, but im not 100% sure, someone else can confirm it. As far as i know, the quad is not able to know its direction accurately without the compass (gyros are not good enough because of drifting inaccuracies), that's why you should not try position hold without the compass.

    btw, do you have a sonar? or your using altitude hold with only the pressure sensor?
