For some time now, the quad has been rolling to the left in all flight modes. I’ve tried recalibrating the accelerometers without success.
Any suggestions?
Thanks
Post a link to a single .bin file of a flight with that issue.
you should probably switch to copter 4.6, and soon to 4.7
As said, a .bin file will be key to finding a solution. But in the mean time, check that you haven’t accidentally added any roll trim on your radio. All the radio trims should be neutral (I disable mine just to prevent finger trouble)

Is ur cg imbalanced that can cause that
The CG is OK, the radio control trims are at zero. Here’s the flight log for the “acro” flight after recalibrating the accelerometers where the quadcopter rolls to the left.
Thanks
Your roll channel centre on your radio and what ardupilot is calibrated to with the trim value doesn’t match. either you have changed something on the radio like trim or recalbrated it or some other offset like extended range or you had trim or something on or didn’t centre the stick properly when calibrating the RC input.

RC1 (roll) is sitting level at 1385, and the RC1_TRIM value is 1495. The trim value sounds right, but the graph at 1385 means the quad is always getting a roll input when you neutral the stick. Check your radio calibration in MP to see what it’s outputing. I’d say this is a radio issue.
Edit: I’d also check the pitch (RC1) because it’s slightly out too. You probably didn’t feel that one because the roll was so far off.

Hi Allister, I did as you said. I calibrated the remote control in MP and now it works properly.
Thanks
