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
