Questions abount PTCH_RATE_SMAX and RLL_RATE_SMAX on AtomRC Wings

[juvinski]

Hi guys,

I have 2 wings - an AtomRC Dolphin and Swordfish, and according with this topic:

New fixed wing PID system and autotune

@tridge current Autotune give bad results if plane tuned in calm day. Here graph from atomrc dolphin: [image] params show previous values, tuned in calm day. And log show params tuned in windy conditions (about 30-40km\h wind). Autotune perfomed about 50% throttle. As we can see D lowered about twice. and here oscillation at start [image] also i think D bad for planes… here video takeoff in windy day after autotuning in calm day [AtomRC Dolphin Поставил камеру заднего вида.] …

I should lower the value for both parameters - PTCH_RATE_SMAX and RLL_RATE_SMAX.
I’m lowering - now I have both in 50 instead the 150 and I still having oscilations.
My questions are:

1. My procedure is lower the SMAX, run an autotune and fly. This is the correct procedure or just lowering the value I don’t need to run autotune again?
2. What would happen if I disable both SMAX parameters ? (setting with 0).

Thanks
