I am finding that I occasionally need to go even lower than 90hz on some brushed. My boss 7 is happiest with two gyro passes at 70hz… And the 2nd order D filter at 120. But anything you think is helpful is always fair game for the wiki. No need to ask. I guess it’s the same procedure … I just start it all off a little lower on brushed. | I am finding that I occasionally need to go even lower than 90hz on some brushed.

+ | Got some feedback for the Kalman beta filters, been experimenting with a 6" 2204 on the Dedicated board (and brushless fork). Followed your instructions and have it settled and flying at 90/140hz and and 2nd Dterm at 120hz. I originally tried 1st at 70hz but was getting some resonance and wasn’t able to get D PIDs on roll and pitch to any decent level without horrible throttle/ | ||

+ | A bit more feedback on the Dual pass beta filtering on the 6 inch brushless; so I lowered the D Term 2nd to 70hz while keeping gyro 1 at 90hz, 2 at 140hz (not sure it was the correct thing to do) but with it I was able to add Torque Boost without quad flying away. Flips very cleanly now with nearly bounce back and nearly no propwash on descends in it’s own dirty air. Nice stuff. | ||

+ | My next test is the 0603 whoop which flies like a dream. Will see if I can get it the same and then wait for the D term passLooking forward to it all | ||
