Overheating Motors

I’v recently built my second quad and transitioned to a 6s battery running 1750 kv motors. It’s a 5 inch frame with 5043 triblades running ardupilot on a h743 slim with a 45a 4 in 1 Mamba ESC. The motors get Extremely hot flying to an altitude of 25m and then landing in guided mode.

I’m going to start my first logs and would appreciate recommendations on which to run to correct for this issue.

Thanks

Post a link to one.

You are running some old firmware. Update to latest Stable before spending any effort on troubleshooting.

You don’t have to create new posts just to remove an access requirement.

Gotcha, which parameters should i keep an eye on?

Please let me know if i did it properly, don’t want to leave any open doors to my pers info.

This is the reason they are overheating and the metric to look at (RCout) to determine if you have output oscillation. And you do.

You could follow The Configurator at this point and work thru it. If you want to change a few parameters to elimate the oscillation start with these:
PSC_ACCZ_I,1.6
PSC_ACCZ_P,0.08

Don’t run another Mission. Just hover and plot the same outputs. If the oscillation is still there drop the Rate Pitch/Roll PID’s by half and try again.

This is kinda confusing, I’ll look into it and see what I can figure out.

Thanks

How did your Rate Pitch/Roll P&I values get to where they are now (0.27362)? Looks like Auto Tuned values. If so they won’t be good with output oscillation. This is one of the 1st things you like next to vib levels.

I messed with some of the PID settings after watching tuning tutorials and before reaching out for help. This issue has been consistent from the day 1 and I assumed this would help correct them enough to run auto tune. It is weird that the 4s quad i built runs hot but not to the extreme this build runs. I did account for the higher cell count in the initial tune

Well for a 5” with the thrust/weight you have you went the wrong way. Do what I suggested and make a hover flight for a minute or so.

OK, Def need to build up my understanding
