DJI P3P 07 Jan 2018 after cold IMU

A test flight after IMU calibration in -5C temperature ...

How ?

First place AC out there without battery to cool down.
While its cooling down sort out a level in all horizontal planes a non-metallic, non-magnetic pad to stand the AC on. I use a floor tile with spirit level.
Switch on RC / Tablet and connect those two ready for AC powering up.
Take a moderately warm battery so it works straight off ... and plug in to AC
Power up ... get GO locked in and start IMU calibration immediately before warm battery affects IMU.

I'm not sure - but it may be possible to do IMU calibration with a similarly cold battery ? If I find my AC warm up time next flights still has appreciable time - I will try with a cold battery - one that actually is too cold to fly !

This video is just to test after calibration to make sure all ok.
