LUX Float VS Rewrite PID Controller in Betaflight
#1
In Betaflight there are Lux float (PID controller 2) and rewrite (PID controller 1).
What are you flying and what are the differences between them in terms of flight characteristics?

Rewrite is what I only use these days.

IMO not much difference in flying anymore between rewrite and luxfloat and rewrite is easier to tune. Once you get it dialed in they should flies the same.

The major problem with lux is that 0.1 difference in pid is too much for perfecting a tune so with the way cleanflight works it's a bit tricky

I would agree that lux and rewrite are very similar but lux comes almost perfectly tuned for me. I started w Luxfloat, then went Rewrite for a bit, presently back on lux again, to me it flies more my style. Very little pid adjusting needed.

You should try MW 2.3!
Smooth as butter. I just figured if the creator of betaflight prefers mw 2.3, well then I'm going to try it. Loving mw2.3 with boris's pid suggestion.

Boris has optimised the code of the MW2.3 controller since re-adding it, thing I love about it is that its very smooth on the middle band, almost like it has built in expo (running 15% expo on roll/pitch with it) and on the stick ends it uses manual actuation like acro plus so you can still have snappy rates, but I guess you gotta try it out yourself to judge.

Your going to completely forget about lux or rewrite after flying mw2.3. It's so smooth. You will probably just have to mess around with expo and rates to get the feeling you like.

Seems like MW 2.3 is just higher resolution tuning. And each change does more incremental small adjustments

But thank you all for the suggestions Smile
I am going to give that a try !

According to Joshua Bardwell as of 2.6 lux and rewrite are the same. The PID scaling on lux didn't have the same resolution as rewrite and you couldn't fine tune to a smaller decimal ie .05
If I'm wrong... Well don't listen to a noob

That's what I've read as well. But I think Boris said you have to double your D term if going from rewrite to Lux

i like pid 1 over luxfloat  just because it seems easier to tune, and my motors sound a bit funny on luxfloat  i will try mw 2.3 after the comments above because how could Boris possible be wrong  Smile
