What was the ambient temperature at the time you did the calibration?
The latter. Who knows what kind of condensation can build up when it's inside a refrigerator!Guess I should put it in the fridge next time I do imu cal, lol.
Should I close the door and do imu cal with it inside? Or cool it and then do imu cal before it warms up outside the fridge?
During the cal process, the phantom has an internal heater that will heat it to the max temp. So if you start the imu cal at (making up numbers here) 25 deg c and the max temp is 50 deg c (again, made up numbers here), then the imu cal has accurate data from 25-50 deg c.Guess I should put it in the fridge next time I do imu cal, lol.

Theoretically you'd want it calibrated for the whole temp range, so starting it when it's cool is probably a good bet. I'll wait for confirmation, since I've not had to calibrate and have had no issues flying even at height.So would it be logical to think that if you calibrate with a narrow temp range as TJ states the sensors might not be so accurate once air born and at altitude? The air up there tends to be quite cooler.
What's your address?This makes a lot of sense with my first 3 flights today, it must have been 3 mins for my IMU to warm up on my first flight this morning (730am uk so pretty cold). My craft was on for a good while the other night and would have been very warm when i did the advanced IMU calibration as it was one of the last things i did while messing about with settings. So i will stick it in the garden later tonight for a bit when its cold and then bring it back in a do another, then see if it warms up quicker on tomorrow mornings flight which i guess it will.
and blaming it on DJI for not making the Phantom canine resistantIThen i would probably be the first posting " Dog Chews up P3".
Glad it worked out.I did the cold calibration late last night, and this morning on my first flight the IMU only took 42 secs to warm up, instead of the 2 to 3 mins it was taking yesterday. Very pleased
