Turns by itself

[Ed Hahn]

Lately when I am flying my bird will make a left all by itself. If I keep going it will turn around complete.
If I stop and then straighten it out I can continue to go. Anyone have any ideal why this is happen ??

Have you asked customer service yet? I would think a calibration process would be in order. I have the H and not a Q500 so I can't claim any expertise with your bird. The H has a calibration process for the ST-16 and a separate one for the bird itself. The circular flying for the H is referred to a Toilette bowl and is usually corrected by calibration.
