Hi - I decided to give the new Speedybee F7 V3 a try because everyone talks about how quiet the gyro is at low frequencies. Which it is. However, I seem to have a strong peak of noise just on the pitch axis at 136hz that is getting through the default filters and pids. Think this is a gyro issue? Roll axis is clean. If it were a build issue it should affect all axes right?

Running BF 4.3, default pids and filters and rpm filter is on. Should I just lower my dynamic notch frequency and give that a try or RMA this FC?

   

Solved this by adding 2 dynamic notches with a Q of 400 and lowering min threshold to 100hz. Noise gone and prop wash is no worse with extra filtering that I can discern.
