Micro tuning techniques - different than larger quads


That explains it. Lol


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:


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:


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! !


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.


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.


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


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.
