"If you are having problems with  v3.2.1 on APM 2.x hardware and your multirotor is unstable and won't sit still but worked fine with v3.1.5 or v3.2, try changing the parameter INS_MPU6K_FILTER to 20 or 42 rather than the default of 0. The value of…"

James Lummel replied to Rayleigh's discussion Motors not spinning at low throttle in ArduCopter User Group
"BTW- forgot to add that even with calibrating the ESCs the motors don't always spin up at the same speed, OpenPilot for the CC3D flight controller even has a calibration routine for adjusting this during board setup for instance. So that the motors…"

"The calibration needs to be done with the transmitter as the PWM signals will likely vary from what the arduino uno and potentiometer is putting out.

And while calibrating with the arduino uno and potentiometer will make the set points on the ESCs…"

"Look forward to hearing back how it went!

"Have you tried replacing the foam over the barometer and blacking out the inside of the FC case around the barometer?
