Been talking about low RC smoothing in your comments for a minute now. It was intended to help folks make BF feel like KISS/Fettec. Glad your finally preaching the good news!

[DoctorrMetal]

Very useful, didn't understand why my stick feel felt worse than with default. Using elrs 250hz most of the time! Great stuff! Used HD freestyle last flight and it felt very off

[MCsCreations]

Oh, really interesting indeed! 😃
Thanks a lot, Mark!!!
Stay safe there with your family! 🖖😊

So I've been playing around with pid toolbox and you can see the latency added by extra smoothing but pumping up feedforward does close that gap to where the traces for gyro vs setpoint perfectly overlay. Brian White has a great video on it.

Appreciate the explanation, thank you! For sure going to revisit some rc smoothing settings on my qwads.

[IvanEfimovLimon]

Thanks for the video, Mark!
Im curious to see longs with smoothing off and comparison :)

Hey mark hope your having a blessed and merry christmas and a blessed and happy new year111

[stuart]

Great video, your explanation makes sense and is appreciated!

[ClareFPV]

Fantastic video. Great explanation about RC smoothing and use cases.

[pirateradioFPV]

Yeah, guess it comes down to whether it's worth it or not. Someone might even buy into the faster protocol to have even more smoothing with the same stick feel. I doubt most people can tell between a 5ms and 8ms link, though. But it all adds up, for sure 😊

Running 250hz and 150z elrs and I don't notice any differences except in blackbox. RC command is always stair stepped even with 100 rc smoothing

[outboxfpv]

Nice one. After playing with presents how can we reset to the default settings?

[aakashjana]

Not sure if its relevant but my tx16s gimbals now fluctuate quite a bit about center after i switched off the ADC filter on OpenTX. I had to add about 5 deadband just to stop the quad moving with stick centered. So in my case would RC smoothing help?

[jas-FPV]

Your Audio PIDs are off 😄😊or is it microphone propwash 😃
Besides that, thanks again for more knowledge

[moshecohen]

Hi, thanks for your work!
Do you any insights on using the DJI Remote Controller 2, with O3, and Goggles 2?
There is an option to choose Normal SBUS or SBUS Baud Fast.
Upon inspecting the blackbox logs of RC_Command between the two, I see the same 200Hz 5ms link speed.
What is the point then of selecting SBUS fast?
At 200Hz, which feedforward settings should I choose?

i paired my knowledge from your Video "The BEST module Radio Link for 2022" with the tip from this video now i got following setup and my toothpick flies really good, i have a really locked in feeling

Setup:
1s 75mm Biblade 1202.5 11500kv AIO Board
ELRS 500hz
no sync on arm
Tel Ratio: Off
RC Smoothing: Off
Jitter Reduction: 5
Feedforward Smoothing: 60
Feedforward 140 on Roll Pitch Yaw

Jitter Reduction at 3 and ff_smoothing at 65 works also great. Turning off RC Smoothing did it, 4.3 is now perfect for me. Thanks, thanks, thanks.

Is crossfire just outdated these days? No one talks about it anymore. it was the defacto standard only a few years ago. A lot of us still use it because we have it already. I have no clue how to set smoothing for crossfire.

[CrawlersCampRc]

Great vid thanks mark! Can see what your saying by one would be defeating the purpose of other. Does betafiight have a frsky r9 preset?

[RCRitterFPV]

I want negative FF haha.
the are you sure, looks good to me, lets just chill here for a sec puff puff give mode.

[SupaflyFPV]

I agree that there is the issue of low pass filter delay on the RC signal, which wasn't getting much air time but was concerning me and I've been experimenting with the point at which RC noise creates observable issues when you reduce the smoothing. But to turn off the RC Smoothing completely seems a bit extreme when the default smoothing on a 500hz signal takes it only from 1ms to 1.5ms...can I assume that you found the noise of the unfiltered signal to be so low that it didn't make a significant difference? I didn't get my ELRS system going yet...
