Yup, you are correct Sir, for I meant to say, "check" everything in settings as updates might reset parameter choices. See post #14.
Was thinking ahead of myself. True.

Not so wise that DJI ever thought to recommend it - there's nothing about it in the manual or the DJI firmware update video you linked.
It seems to be a forum myth that's crept in.
Some users love to feel that they are doing things that make their flying better or safer.
Some of the things they do don't make any difference but because forumers keep advocating, others feel they should as well.
My belief (based on experience and observation) is that after updating, all you need to do is go back and check the settings that have reverted to default values.
What ever they said here. HahahaI totally agree. Through 3 Phantoms I have never calibrated the IMU. P2V+, P3A and P4. All rock stable before and after firmware upgrades. But definitely check the values prior to each launch, and your custom settings after a firmware update.

IMU Calbiration Frequency - Offical line
I just added to that thread.
As I said, it IS in the manual. Twice.If it is that important then it would be in the manual.
I guess do what makes you comfortable. I'm just saying rock solid performances with all my birds after every firmware upgrade.
But absolutely nothing suggesting IMU calibrations need to be done after updates?Scrolling up to post #24 above, is this "And calibrating the IMU is indeed mentioned in the P3P manual I have here, page 52 under Initialization Errors."
And "Also, one of the Warning "Red Flashing Alternatively" indicators is listed as "IMU Error" in the manual. They don't call for calibration here, but hey, what else are you going to do?"
Unfortunately DJI people on their forum are sometimes not much better than the newbies they are responding to.Lastly, this isn't just forum user hysteria. DJI employees have recommended this procedure countless times (though not on this forum as far as I know).
This reinforced concrete and steel nearby,keys in pocket, next to a car, flying near a steel structure blah blah blah, is a bunch of bull crap.The compass doesn't fail at all.
A compass error is your compass telling you that you are in an area where the earth's normal magnetic field is distorted by a lot of steel nearby.
Most commonly this is reinforced concrete.
If this is the cause, recalibrating is the wrong response.
The correct solution is to move away from the steel causing the problem.

The compass is not that sensitive. If it was that sensitive it would never calibrate correctly at all, as there are 14 small but powerful MAGNETS in each motor, on each arm setting just inches from the compass. So the compass is surrounded by 56 strong magnets, yet you are not supposed to calibrate the compass within 100 feet of any thing steel. Makes sense,
Sorry but that's very wrong and 100 feet is an exaggeration.This reinforced concrete and steel nearby,keys in pocket, next to a car, flying near a steel structure blah blah blah, is a bunch of bull crap.
