Looptime and PID?
#1
Looptime. Why do some pilots use lower or higher looptimes? Is it all dependent on the hardware you are using? I lowered mine to 500 and felt like I was getting washy turns. I brought it back up to 1k and I dig the feel more than before. Should I go a bit higher to get a more "crisp" response or am I thinking about this all wrong? I understand that changing looptime means adjusting PID's as well. Just wanted to get some input on why you fly what you fly it at.

Different looptimes require different PID tunes.

With 1000 loop time, the PID loop runs slower than 250, but slower looptime gives you more effective filters, with 250 no matter how much i drop the pids i always have little oscillations.

But I found with a faster (lower) looptime I can get a better tune that runs higher P values to make it feel a little more locked in.

lowering looptime means you will have to raise PID values, because the more samples that are taken and processed by the pid loop the faster it can react and the less likely it will be to overshoot the target attitude (and cause oscillations)

I run as fast as your fc can handle. It will be more locked in.
