Chris Rosser has produced a couple of informative ArduPilot setup and tuning videos here on his YouTube channel.

Also while many of Chris’s other videos focus on BetaFlight, there are a good number that are relevant for all multicopters. For example, this video discusses how to pick the best propellers for your copter.

Thanks Chris for using AP and helping inform the community about the challenging area of Tuning!

The ArduCopter methodic configurator tunning guide also uses a video from Chris Rosser explaining ESC configuration.

Great videos! I also recommend checking out Part 2 (Filter Setup) and Part 3 (PID tuning).

Has anyone purchased the ArduPilot Tuning for Multicopters course and would recommend it?

It would be nice if he would correct the errors and miss-information regarding ArduPilot that some devs reported to him, instead of ignoring it. And it would be nice if he would start using ArduPilot Methodic configurator software to get more reproducible and traceable results that actually follow ArduPilot best practices.

His course seems to focus primarily on PID tuning, which is where I’m currently stuck. I’ve done over 50 Roll and Pitch test flights of various PID settings and don’t have the knowledge to choose the right values:22.09.2025 - Google Drive. I get the impression that PID knowledge is protected and only shared for a fee.
The course is quite expensive ($499) and there is no guarantee that I will find answers to my questions there.

It’s available for free and has been for a decade.

Yes, but there are no practical examples demonstrating the use of this knowledge, such as those demonstrating the use of the PID review tool with a detailed discussion of the generated graphs. For example, if I knew which of the graphs I posted represent good PID tuning, it would give me a lot of knowledge.

Andy’s 7" Build Blog tuning video has general application content.
Getting the perfect tune
I would only suggest Ardupilot Dev YT videos and avoid the “smash the like and subscribe, ring the bell” monitizers.

Yes, I’ve seen that video, and it’s definitely helpful. However, I didn’t find the answer to these questions:

  1. The RATE.Out graph in the MP Log browser. The ideal range is between 0.1 and -0.1. The question is, should this range be achieved during standard flight, hovering, or aggressive maneuvers?
  2. If the above RATE range is above 0.1, which filter should I lower, the D filter or the Gyro filter or both?
  3. After performing Autotune on a 14.5 kg Hexa X with 22" propellers, I achieve almost the same PID values ​​as the 7" drone in the video above. The MethodicConfigurator manual, section 6.14 “Optional PID adjustment,” states that PID values ​​should be higher than the default values ​​for larger drones. Am I getting the wrong values?

No, a good autotune in low wind with correct notch filters is the authorative best result for your vehicle. Regardless of the rule-of-thumb tips that the AMC tunning guide has.

Can you paste/share the link where other developers havs discussed about some errors in his videos? Thanks

No, I did not store a link to it. You’ll have to look for it yourself.
Bottom line is: use ArduPilot official documentation and videos.
They are just better.

For starters, see my comment in the comment section of this video.

I watched a few minutes of some of the rest of the series and continued to find inconsistencies and lacking knowledge, but it’s a waste of time to continue to engage, as he has shown zero interest in improving his “course” or working with the team to correct errors.

I just stumbled across this thread. And in case anyone else does in the future, I figured I’d throw in my two cents. I had tried to follow Rosser’s content for setting up ArduPilot on a fresh build and still came back to the ArduPilot docs. I have found that if done correctly, it’s pretty simple to follow the docs and get a vehicle from flashed to flying. By way of background I’ve only been using ArduPilot for about 9 months on builds up to 8” so take that for what it’s worth. But, like anything else, after some reading and learning things started to become easier.
