I just got an X4 recently. It came with Arudcopter loaded on a Cube Orange+, but I switched over to PX4 and did a few test flights. The Cube Orange+ is hard mounted, but I though that was okay for the cube since two of the IMUs are mechanically isolated. My drone was a bit twitchy during the flights so I checked the accel logs and sure enough I’m seeing big vibration. Plots are attached. What is weird is that the first 2 IMUs are high, but I thought they’d be lower because I though the third was hard mounted. Any idea what is going on here? I’m at a loss. I could do some vibe isolation but that shouldn’t be needed here. I’m more concerned and the two IMUs showing higher accel that the third.
Thanks in advance.
