Oscillation in roll

My DIY quad + oscillates in roll immediately after take off at about 1.5 hz with the amplitude increasing.I am using A/C 3.0.1. How do I damp this? Is it too much stabilisation or too little?, Richard

In general osculations are the result of too much P and not enough damping. Have you tried the auto tune function?

Hi, thanks for the reply. No have not tried auto tuning. What parameter changes the damping? Richard

Just watched autotune video, would love to try it BUT it is so unstable in stabilise mode the flight is only a few seconds before the osc gets out of hand, Richard

Go back to the default PIDs and start again.

Thank you, will try again, Richard
