Micro tuning techniques - different than larger quads


#201

That explains it. Lol


#202

The tune is feeling good but I do notice that in hard banked turns, it’ll dip an arm and get out of control and I’ll have to “catch it”. Am I just reaching the limits of thrust on these brushed motors, or is that something in the tune? Opinions? Thoughts? Wisdom? :smiley:


#203

Either that’s a bad motor (not likely on a new set Of darks) or its tune related (most likely). I find it near impossible to get my brushed quad out of sorts in any manuver. We could throw a few more “guess tunes” at it if you like. If your dipping just 1 arm - then that seems both pitch and roll related. Basically I would just bump both pitch and roll P and D up equally by 10 points at first and then by 5 points till that behaviour stops. I wouldn’t think you’d need a total increase of more than 15 or 20pts. Hmm, on second thought - raise yaw P to 125 first and see what that does and then do the pitch and roll thing. If it helps then bump that by 5’a till you hit a point of diminishing returns.

That was kind of my plan, but my numbers seem SO HIGH already…brusssssshhhheedd is cray-cray! :stuck_out_tongue:


#205

You’re still well below where I and @bobnova landed! You should see the tunes I run on 2s micro brushless - P close to or over 100. D in the upper 50’s and 60’s. Lol I like a quad that can not be forced into any bad behaviors. I don’t mind a tiny oscillation in prop wash, but arm dipping is not allowed! !


#206

If you have vibrations getting to the fc then high D can actually cause strange dipping of arms as the gyro gets swamped, check motor temp and prop condition/balance.


#207

Hmmm, that sounds interesting. It usually happens in a quick hairpin, or when I’m at the start of a high-speed sweeping turn that I’m banking hard into and as I add yaw it tends to dip in and down into the turn.


#208

Sounds like the tune is low to me. Vibration related bad behavior wouldn’t be so specific to just high g manuvers.


#209

I just adjusted my tune ala @NotFastEnuf…will try it out on my “lunch break” instead of doing laps in the pool…exercise is for suckers. :stuck_out_tongue:

Vibration swamping of the gyro signal can build up even in a hover if you have one corner bad, depends on frame type and many other factors, polycarb frames being most susceptible. I’ve had these problems and am a fan of high pids for small craft especially whoop sort of size, so I tend to keep D relatively low and work with high P to get the tune how I like. Relative meaning still possibly into the high 30s but paying close attention to motor temps. Whoops are all way up nearer 70/80 D.

wish there was a "super like"
you are defiantly a great teacher and i am so glad you spent the time researching and developing your method.

You guys inspired it cause it was discovered during our communications as this thread developed. I appreciate the compliments but it’s really a credit to our community - I often wonder what the hobby would be like for me without you guys - or if I’d still just be flying airplanes. I found this community when I was on the verge of giving up on micros. You guys all encouraged me and helped me through the learning curves and got me to the point where I started having some unique and successful ideas. I remember I used to go outside and check the wind to see if it was good enough flying weather. That was actually a thing! And I used to tune the “old school” way or “stingy” way but it never flew good in the wind. It finally clicked on a super windy day … I wanted to see if I could tune out the bumpy ride. It finally worked with triple digit pids, flew amazing, and was a totally random experiment. Tons of fun.
