Hi,
Working on a 22inch quad with a winch payload delivery system. Our team is new to Ardu and needs some advice on what we are potentially doing wrong. Have tried switching between external here3 compass and internal, also have RTK module connected. Ran successful flights earlier in the day but started getting mag anomaly errors and yaw misallignment errors. Frame is custom built but has vibration damped avionics.
Bin of crash attached, please help!
The crash is caused by Motor1 or ESC1. It was commanded to maximum output because thrust was lost for some reason.
Potential Thrust Loss (1)
What ESCs do you have?
Yaw realignment messages are relatively normal. The yaw reset, ground mag anomaly and lane switches are not so normal - all of these came after the initial incident, so maybe the GPS stand got damaged or moved.
Your external compass calibration looks reasonable, at this stage leave the internal compass disabled. If you can get to do a flight with lots of different maneuvers and ascents/descents then we can improve the compass calibration. The battery current monitoring will help a lot.

Thank you! We have Flycolor xcross escs, dshot capable, we are thinking its a motor issue, had a similar thrust lose problem today. Flys for a while, then gives out.
A typical cause of that is bullet connectors - if you have them remove completely and replace with quality solder and heatshrink.
Strangely enough we replaced the motor, checked all connects, all joints are hard soldered, still faced the same thrust loss issue. We did notice that the area we were flying is a higher altitude which could affect our thrust to weight. Would that cause only thrust loss on that one side though? Thanks again.
No, altitude doesnt have as much effect on thrust as you would expect - it takes a change of many thousands of feet before you require a different prop size.
