I think if Mavics were landing negative every time, there would probably be hundreds of posts rather than just a handful that I've found. I looked at the airdata on my older mavic and I saw a couple negative landings out of dozens of flights, but it wasn't *almost every time* and that is why I...

Yeah but how is the flight environment changing within seconds? Flight times do not matter. It lands negative each time.

I guess I will exchange it. DJI support has been ignoring me and would prefer to have a drone without a defect out of the box. Sounds like from the posts here it is not serious but maybe it could be down the road.

Deviation is between -1 to -6.8 feet, not meters. Mainly am hoping I would not get unexpected water landings.

Took out nearby to test again. When it was cold after just turning it on, I took off about 20 feet in the air near a utility pole that I estimated to be about 18 - 19 ft and then landed within less than a minute. First landing was -4.5 ft or so. I kept retesting taking off and landing and...

I can double check that again. I'm going to do a few more tests today.

That's an interesting comment about the altimeter heating up. I wonder why some Mavics would have this issue while others do not. That sounds like a hardware problem if that's the case. Someone suggested to me to put try it while it's cold (like put it in the refrigerator for a a bit) and then...

Well DJI replied and said it's fine but I think they though I landed in a spot lower than where my takeoff was. But as I noted before, I have taken off and landed in the exact same spot almost immediately and it shows the negative altitude on landing most times. Anyone ever see this issue or is...

I recalibrated the IMU on a flat surface in the house and also recalibrated the compass. I tried to do the VPS calibration with DJI Assistant 2 1.1.2-2 and 1.2.4 (latest link on the site). Both will not allow me to recalibrate with the Frame Alignment error and it keeps telling me to reboot the...

Hi guys, I got an official refurb mavic to replace my last one (that I lost in the water). Anyway, one thing I am noticing with it is that when it lands, I have a -1 to -2 meter reading when I land and touch down. Never saw this with the old one. Doesn't seem to have any problems with flight or...

Glad to hear this. I will be traveling around Lanta and Phuket and I will exercise caution and have some "paperwork" just in case. Avoiding crowded areas and obvious police presence is probably a good idea so you don't get into a situation. I'm interested in beach and island shots for the most part.

I just got back from Belize which does not allow tourist use of drones and I did read reports of them grabbing and holding Phantoms and Inspires at customs which are much bigger, conspicuous drones than the Mavic. However, I saw someone flying what might have been a Spark on the caye I was at...

kindnation, thanks for the insight on how it is from a thai's perspective. I do not really want to submit any forms but I will monitor how things are going for drone pilots there and play it by ear. As long as customs is not confiscating drones, then it is probably not going to be an issue. My...

It indeed does not look good. Was hoping someoke could weigh in on this that has been. I think I may not take it because of reported customs confiscations and no ways for personal permits in the cayes. I could roll the dice but I will only be there for 5 days and cannot really jack around with...

Roger that. I think I may take the steps from this post and see if I can bring some kind of document with me if cops get involved to at least show some due diligence. How to register your drone in Thailand
