I am trying for several weeks now to persuade my arducopter controlled quad to fly. That is not succesful due to erratic turning motors. It appears that each motor has its own speed that constantly varies, even when the thing is standing on the ground. Sometimes a motor just stops while the rest keeps turning: see this video.
I checked all inputs and outputs but couldn't find anything. Using a DJI flame wheel with Opto ESC's (these can't be calibrated) and DJI 920 KV motors. This is the original DJI F450 setup. In fact, everything works when I replace the Ardupilot by the Naza controller. Maybe the Ardupilot is defect?
I am at a loss what to do. Does anyone has some ideas what I am doing wrong? Any help is greatly appreciated!
I just took a screenshot of the PIDs i'm using for someone else.
Try these and see if it's more stable (see attachment).
Thanks for the screenshot! I'll be flying in the wild this weekend so I can check whether it *really* flies. Your parameter settings might come in very handy.
