Yaw pterm cut12/8/2023 I have Bidirectional Dshot enabled in the configuration tab, but is there a 'Dynamic Filtering' option in there? I am referring to it as the least worst tune I have, mostly because it doesn't fry my motors. It's doing bad, and yeah I know these are very low D's, I am not familiar with the default filtering settings since I just override them but why is the Gyro Notch Filters all off? You have RPM Filtering (Bidirectional Dshot) and Dynamic Filter turned on in the Config tab? Please don't take offense to my frankness, but what you are referring to as a "decent" tune is likely a "least worst" tune given your settings. For 4S your D's should generally be in the 40-50 range with P's about 1.5-2x that given proper filtering. And that leaves your P at 3x D which is surprising your quad isn't shuddering like crazy on turns. (1, 07:02 PM)the.ronin Wrote: Yea those are crazy low Ds. It's a 5 inch quad, but it doesn't fly that good, it's decent to what I flew before but it's not good, it's twitching and stuff.Īs for turning down the filtering, if I do it my quad is making weird sounds when I'm arming and in the air, if I take it to defaults(1.0 on both) it can randomly take-off on arm. and on other quads I've seen as much as 50 D (which is kinda crazy lol). All quads are different, on my 3 inch quad I have D set to something like 16 or 17. If your motors are not hot after this then ur good.

Maybe turn down the filtering to make it even better (turn down the filtering as in raise the sliders to right). Seriously though if ur quad flies good then leave it. (Again, this is just an off the cuff assumption I'm making, but it sounds legit right D lol) On a 7 inch quad after a flip there is a lot more inertia in which the D term has to help fight against. so on smaller quads (and I'm just using logic here and guessing) one would assume you wouldn't need as much D ANYWAY. and on other quads I've seen as much as 50 D (which is kinda crazy lol).ĭ is what fixes any errors the gyro reads AFTER the fact. If you get a decent tune from these PIDS then leave it that way. With that tune I don't get hot motors, and I have a 'decent' tune, I don't know how I get away with such a low D gain but yeah. I set my filters to 0.7 on gyro and D-gain, and set my PIDs to: I set my filters and PIDs sliders back to default and it made 0 change, I tried using bi-directional D-shot, I flashed my ESCs with blheli_s 3.73 and enabled everything according to JB's guide, (1, 05:55 PM)SaHaRzZz Wrote: I've re-uploaded to a different site, I'm using a 4s battery. I tried searching for more info about it, I also watches JB's video about hot motors:īut thankfully I didn't have this kind of issue Probably something with filters I guess? is it normal for motors to get hot at low D gains? Is there anything more I can do to reduce my motors from getting so hot? This is the sweet spot for me not getting hot motors(they are still hot but not as much as before) and an OK tune, but I still need to up my P gain, but I am unable because of the motors getting very hot when I hit 20 or above in the D gain territory.Īnother thing, about the quad making sounds and shaking a bit(sometimes taking off because of that) at the moment I arm, I applied a bit more filtering:Īnd it seemed like it did the trick, if I try to put it at 0.85 the quad starts shaking again so that's the minimum I can get away with. The hot motors, my quad didn't feel good at all, and it shook from the moment I hit arm. I watched about 2-3 hours worth of tutorials about PID tuning and spent around 1-1.5 hours to try to change some things, because in addition to My motors were getting really hot with the default BF 4.2.2 pids,
