My crux3 gained some weight after swapping the camera for the Caddx Turtle v2 system, and being a 1s drone, flight performance and characteristics changed as one would expect.

I'm waiting for an order of props to come in so that I can try it on a 3016 tr-blade and see if anything changes (currently with 3018 bi-blades), but was wondering if there are anything typical setting that could/should be changed in Betaflight for this type of circumstance.

Anybody has any tips for this?

tks

Watch Bardwells videos on tuning for starters.




I've watched them and still have not much of a clue. After that, well, maybe Hug could point you to somewhere, he generally has good ideas in these sorts of areas.

if you add weight, power to weight shrinks: lower power to weight requires higher pid values.

you could incease the multiplier in the pids tab, small steps, allways check your motorheat after a hoover test for excessive heat, step back if they cook. increase to a locked in feel you are looking for or until you get some fast oscillations, step back a littlebit if so.



the pid tuning tutorial of joshua, 6 years old, doesnt match todays amount of features anymore.
there are general rules about pids in it, but follow that tutorial wont give a propre tune.

Thank you guys..

I'll try playing with the slider and see what happens.

It took me months to figure out a method that worked for me. Eventually it came down to just accepting that I don't actually know what it's doing, (outside of correcting setpoint error) but instead, learning what each value corrects for. If I see a specific kind of issue, I just adjust it by feel.

The tunning bit is not something I'm very keen on tbh, learning very slowly a few things here and there, it doesn't help that none of my quads can save blackbox.
Building, basic setup, and flying, already has my plate full, once I feel I hit a point of proficiency with flying I might start digging deeper with tuning stuff.

What is PID?

Old cars and planes had physical wire to control steering. You can pull line on throttle body and immediate effect. PID is software - it translates your stick commands to motor ESC.

Maybe low speed you want tight cornering, but driving on highway you certainly dont want steering to be twitchy.

Good PID tune is a broad range. Many combinations of values work. Better tune is more resiliant to damaged props, wind, propwash, broken arm etc.

PID pushed too high, can cause hot motors and fly away.
