Imu cali

[t2adze]

I have done ImU calibration cold one somewhere in beginning of january. No warming up signs. All perfect.
When do i need to recali rate imu? Or do i ever have to do it again?

It's recommended to re-calibrate the IMU after installing new firmware or crashing/dropping your Phantom.

As i suspect a lot of others do, as part of my pre flight check i look at compass and IMU sensor values. Make sure you do this with the phantom on a solid surface. You should expect x and y values to be zero or close. Z Should be at or close to 1 with the phantom kevel given the z axis is measuring gravity.

Change in climate.
If you are going from a warmer to cooler conditions, the IMU warm up times will take longer.

Ok fellas, is there a difference between calibrating the compass in the P3A, or the ImU. I guess I'm asking is there 2 type of calibrations we should be doing?

Yes. There are actually four different calibrations you should be doing. See step #48 here.
