How can I do pixhawk sensor calibration of big size drone?

I wondering how can I do pixhawk sensor calibration of big size drone!

It is difficult to set the seonsor calibraition in big size drone

so I’ll set the pixhawk without attaching to the drone,

Is it okay to calibrate the sensor without mounting it on the drones?

what sensor are you trying to calibrate? Is it the compass or is it the accels? For compass follow this Testers needed for in-flight compass learning. Might depend on the firmware your running but you can do that for compass, for accels I would just calibrate the pixhawk without it being in the craft for that then reinstall it. All really depends on what sensor cal your talking about!
