The setup that I am currently using involves a Voxl2 Mini and the Voxl ESC mini 4 in 1. The ESC is calibrated, and when all motors are spun using voxl-esc tools, the RPM values are accurate across all thrusters. This is also true when the motor test is performed in QGC, the reported RPM is equal across all thrusters.

The issue occurs when trying to fly the drone. When armed, not all of the motors spin at the same speed. Using the RC controller to arm the drone, and putting all control inputs to zero causes vibration issues as some of the motors spin significantly slower than the rest. I re-calibrated the sensors in QGC several times, and this did not resolve the issue. I have attached a brief log which shows the issue, and would appreciate any suggestions about how to fix it. Given that the motors work correctly when tested outside of PX4, I am leaning towards it being a configuration issue with that.
