    Not unless you are already in an area completely clear of all metal, are outside, and have decided this is an appropriate place to calibrate. Instead of calibrating the compass, first try moving to a clear area area outside, with absolutely no metal interference. Compass Calibration Required means you need to move first, to see if it is the location that is the problem. If it goes away, leave it alone.

    Does it show that message when you're near magnetic metal objects? If so, you should not calibrate it. If there is no potential interference in the area, then it's okay to calibrate it.

    You're absolutely right about that because I've taken my Phantom out of the back of my SUV and calibrated the compass right behind the vehicle. Sometimes it wouldn't calibrate and I'd move a few feet away and it would calibrate no problem. I'd occasionally forget about all the steel in the vehicle.

    Worst place to try and launch your drone from is the trunklid of your car. It may be nice and level, but it will immediately generate compass errors. "Step away from the vehicle!" ;)

    I've never launched my Phantom from the trunk of my vehicle. I just removed it from the inside of my vehicle.

    Trunklid, not trunk. ;)

    I've never launched my Phantom from my trunk lid either since I haven't had a trunk in more than 20 years

    I travel from my son's house to my house which is 105 miles. Should I recalibrate each time I travel?

    To calibrate each time you drive 105 miles is totally unnecessary.

    Great thread! I always thought I had to calibrate before every flight, regardless of if I flew in same spot. I have a P4 and have only flew around my backyard so far and each time I've been calibrating it. Good to know!

    If it ain't broke, don't fix it! You are far more likely to introduce a bad caibration in an unfamiliar area. If your last calibration was a good one, and you haven't travelled more than 100 miles, leave it alone!

    It's boot not trunk or trunk lid. Always calibrate before each flight.

    That makes total sense. I always thought it was a bit strange that I had to calibrate before each flight.

    Xomorph .are these people going to replace your drone if it is lost. Don't listen to them. It takes seconds to calibrate.

    Do as you like. However, there is no excuse for not reading this thread in its entirety, as you clearly have not. :rolleyes:

    Question: Does it make any difference if the AC is held steady in front of you and you turn around 360 yourself, vs. rotating the AC on it's axes?

    All my physics and engineering background tells me it makes absolutely no difference, but I thought I'd check with the hivebrain.

    It's much much much easier to get a uniform, steady 360 that way.
