Log whispers, can you help with some vertical oscillations?

[xaidin (Bob)]

Hello,

So on the first test flight of a little 8": It jerked up and down every second or so.
It was flyable, but only as it jerked up and down in a couple feet envelope.
After landing the motors were insanely HOT. Probably messed one up, hot.
Can someone look at my log and parms, and maybe give me some direction?
OH, this is what I ended up with after methodical config.
Only thing I “monkeyed with” was some DSHOT stuff to get the motors to work. Something has to be wrong in there, for them to be so hot?

THANK YOU!

You’ve got ESC telemetry so let’s simplify those filters:

Set:

PSC_ACCZ_P, 0.178
PSC_ACCZ_I, 0.356

Try a hover in stabilized or Alt-hold and see how that cleans it up.

See section 7.1.1 of the methodic configurator tuning guide to understand why motors get hot.

Poster child for massive output oscillation. That will get-em cookin’

Use the configurator.
