Thanks for the video! I had this issue before and implemented the same solution just as an intuitive idea without actually realising exactly why it worked. This explains it 😁
Hello, I'm having a problem with my gyro noise plot graph in PIDtoolbox. It shows normal behavior from 0 to -35 dB at 40 Hz(Pitch). On the roll axes, however, the graph starts at 0 and goes straight to -15 dB at 30 Hz . Is this normal? My gyro has a delay of 1.5 ms, while Dterm has a delay of 2 ms. I'm unable to fix this issue, and it's causing the D term to almost reach 0 dB!
Hi. I hope you can make a video talk about the difference between mpu6000 and 6500 and 9150. Due to the mpu6000 price goes high. Many manufacturers are transferred to mpu6500 which have higher samples rate.but in the real world I find that for bf and inav sometime will preform even worse especially when you are not tuning will. Is there any tips or something needs to mind when using mpu6500? Thanks for everything you do.
@@PIDtoolbox I see there are fc use bmi270 but read the data sheet it’s 6400hz lower than mpu6000 8000hz. It’s bf prefer lower noise than higher frequency?
No. It’s not that simple. You still want to keep filter latency low and reducing min hz lower than you need will unnecessarily increase filter delay a lot. It just depends on the rig and motor size/prop size/Kv etc. default is good for 5inch or less but as you get bigger props that spin at lower rpm you have to re-adjust min hz. For 10inch it’s usually best around 50-60hz, for most 8inch lifters I set it to 70hz.
