OpenTX ADC filter is messing up your PID tune. Turn it off.

Same here. And i’ve seen people speaking about turning rc filter in BF as well. So I ended up with a quad moving randomly….

Yeah same, I’ve replaced stock gimbals on my qx7 with hall ones, hoping this jitter will be gone but nothing changed, it was still the same even after dozen of calibration attempts. So I said fck it, and erased it from my memory. Thanks Bardwell, wish you made this video a year ago!

Spatty didn't come up with it lool. It is just a radio feature :) Mine was off by default(tx16s) Change your Betaflight Rc smoothing settings too...Manual interpolation at 10ms. Extra locked feel. Oscar Liang has information on it.

Condements oxidize the contents good to know

This is very true, l was wondering why the random comment and then remembered JB's outro!

Also make sure to load the right RC Link preset in betaflight presets tab.

Edgetx has been great for me so far, it’s essentially the same at this stage except for touch support and a few minor changes that will allow a flower latency if you use expreslrs

Yes

I guess FBLs don't do the same filtering that BF does? Do you see this jitter in your heli servos with ADC filter off? I only have one heli right now and it's apart so I can't test it on my side. I was hoping FBLs would also filter it.

@@The8BitHeroI'm sure there's some kind of filtering but it's not configurable in any of them afaik. It's probably not a big deal because compared to quads/escs everything is so much slower on a helicopter.

I fly only helicopter s. I believe flybarless gyros have built in filters.

@@The8BitHero I switch ed to opentx 2 years ago to fly helis. I dont see any jitters. When you observe each channel in flybarless setup screen the channels dont jitter.

The model-specific setting overrides the global setting, however in model settings you can configure the model to copy the global setting.

@@JoshuaBardwell thank you! That makes sense. I'd be lost without your videos.

Or they could have removed the option, and they could have made the default anything. You'd have to review the code to see what they actually did (or ask them and hope whoever responds knows what they are talking about).

@@pfeerick - So true.

This isn't an option in freedom TX

If I remember correctly JB said it was combination of weight and the lens on the analogue camera????

i find it very hard to freestyle on the polar camera compared to the regular dji/nebula pro, its not just the latency, its a way more zoomed in image that feels almost like a 4:3 image stretched to 16:9... the polar is a great camera for long range though as it has great low light and the zoomed in image i prefer in longrange too.... i can get an extra 20-30 min of sunset flying in its soo good in lowlight, now we just need a large sensor gopro to capture that lowlight as well

Considering they are identical in every aspect except for the camera and vtx you can assume that it was a combination of weight and the frame style that will affect flying ability. Potentially the camera also was not what he was used to but that won’t change how it flies

@@willedwards7679 i really dont get much difference in handling with deadcats vs x's, its easier to get better propwash performance and stability on the X but once deadcats are properly balanced and tuned its hard to tell the difference.... now if i changed the camera from og DJI to polar camera i would have so much trouble freestyling it... in fact JB had trouble freestyling the polar when he was doing a review of it and figured it must of been the added latency, although i dont think he considered the negative aspect of the lower fov... i can freestyle the dji cam in high quality 4:3 as well so i know its not just the added latency of the polar.... hopefully more cameras in stock soon so you can swap it out if your into lower latency freestyle

It's not on freedom TX, nothing to worry about

I can't even find ADC option on Mambo (FreedomTX). JB?? @joshuabardwell

TX(radio) so you can use it with a sim on your computer. Buy a good one treat it well you'll have it for years to come.

Because you add latency for the filter on your tx and then on top of that beta flight will still be running the same filters to remove jitter adding more latency. If you turn off the setting it will remove that first setting and only your fc will be running a filter, if that makes sense?

Tango 2 runs FreedomTX not OpenTX. It may have different options.

In my very old Tango 2 (bought it in March 2020) the is this option, so it depends on firmware version I guess.

@@xemlfvrx Hm. I tried a few new firmware but none of it has this option. I assume that there is still some filtering because I often see stepwise lines on my RC input blackbox log.

I can't really see my channel bars themselves moving but i see the values jittering around by 0.1 - 0.3

That’s how it’s supposed to work…….

@@willedwards7679 great! Thanks. I'm an idiot

The noise is causing jitter in this case

ADC filter on increases latency, not decreases it. It's something like a three sample moving average so it adds three samples of delay.

​@@JoshuaBardwell Averaging 3 samples doesn't necessary mean, there is a delay. The previous two readings (buffered in memory) could be averaged with current (time) values and sent within same timeframe as single reading. Would have to look at code, to verify, but would be dumb if OpenTx code waited for every 3 sample periods before sending. This would not be a moving average, just average of 3 values. (ie: would be be like pixelating a linear movement, vs. smoothing) Note: what is being displayed also may not reflect sampling periods. Display updates could occur with much different timing vs when values sampled. Only way to know what is happening latency wise is to collect data on both transmitter, and what flight controller is receiving (logged in blackbox). Triggering a aux switch could be used to sync both datasets.
