Calibration questions

[Flawless]

I was messing around with the desktop simulator earlier, while I had my Mavic on my (steel) PC case.

I took it out a little later (just after sunset, so low light), and got some drift in zero wind which hadn't occurred a few hours earlier in moderate wind. Immediately landed, calibrated compass and IMU, and took off again. Back to normal.

I respect your experiences. And a few others on here. If/when things go bad, you are first to ask for help. But I figured my good experience may help others feel a bit better about the Mavic. It's not all do and gloom. Again, I will try to make sure my opinions sound like just that, not fact.

I'm always a believer in the compass calibration. It's fact that magnetic north is different all over the globe and even real aircraft require this, so I can't see that doing this will hurt the mavic.

Never meant it would hurt. I just said for me, I haven't. I may be way off. I'm just trying to fly for fun and thus far it's working great. Hell. I may be here tomorrow asking for help finding the thing. Again. Just saying, for me, so far it's been great and predictable. [emoji8]

If your beast is flying well, then certainly I would not do a calibration. I do think it probably is over done by some, but it's a habit I have gotten into if I'm in a new area that is a substantial distance from my last flight. Certainly in earlier days of multirotors this was far more important, and those that where caught out with the old toilet bowl dance, don't want to revisit.
The first time this happened to me was with a blade 350, and I didn't know what to do. It just started spiraling and going faster all the time. All I could control was height so I ended up just having to crash it. I was lucky there was no damage but I never forgot that feeling of helplessness

Only time I've felt worse was when I sent a home built kit out on its maiden waypoint mission. I was so impressed with myself for building such a platform. That was until it went around the bend of the local river and never returned. Haha. I had to go and build an identical platform that day so my students wouldn't know the next day that I'd lost my pride and joy.

I by no means meant to give advice. More was meaning to give my personal experience. I apologize if I didn't make it clear that I was purely saying what worked for me. I thought the OP was looking for various opinions. Trust me, I'm well aware I'm no expert. But I do have my own personal experience I can relay. I will try to be more clear that it is only my own experiences in the future.

hi JHSlayer,

sorry for my dumb question, but what it means "OP"?

"OP" is a bundle of sticks.

No, seriously: OP refers to Original Post or Original Poster, the person that started the thread.

thank you for your answer! now i know it.

And all of this time I thought OP was Ron Howard.

I probably read too much into this, but when I look at the values of the compass and IMU in the sensors section, I want to see very short green bars max. If they are consistently long, I would be inclined to recalibrate in a known, clean environment. I just want a larger margin of error before I fly. I have only had to calibrate compass twice and IMU once in several hundred flights, so this is rare anyways. Maybe a bit over cautionary, but no issues so far.
