Testing internal IMU damping solutions of popular flight controllers

Chris, thanks so much for the real world testing. As you say, the vibration levels look good and the internal isolation must be handling those frequencies perfectly. I haven’t had any experience with gas helis; can I ask if you’ve done an FFT on that particular heli? Are the vibes due to the engine much greater than the vibes at rotor frequency and 2*rotor frequency (I’m guessing they are?)

Looking forward to recieving the 3 Pro to do some testing.

Cheers
Jason
