Magnetic Interference

[Cheech Wizard]

I'm assuming there is spring steel in my landing pad? That's 360 degrees of a magnetic ring around my Mavic Pro? Any opinions on this?

Possibly? Set your Mavic on the ground and re-test

Is strange how some steel causes issue and some don't .
I use this most of the time and never has caused me any issues.
I wouldn't lie to ya

I noticed my "radar view" was always off a few degrees until I got it airborne, then it seemed to right itself.

Now, THAT"S a lot of metal.

Yes it is, can't do it from the hood but do from there. And right from over the rear end
I mean .Launched my Phantoms from there .Like I said is strange .

Have you checked to see whether or not the steel is ferromagnetic?

Careful with that - as we've had another Post where a Mavic pilot had a runaway which seemed to be due to the compass and GPS coming into alignment AFTER the Mavic cleared the magnetic anomaly. It does appear that there are situations where the Mavic will report all OK and green for take-off on the ground when it's in a strong mag' field - but it will get into trouble when you lift-off out of that field and suddenly the INS & Compass try to align themselves again. I've seen it advised from experienced pilots that if you notice a difference between the direction your Mavic is pointed, and the direction that the arrow points on your map view ... then move your drone before you take off.

I have experimented taking off from the roof and bed of my pickup several times and don't remember many errors. But I always got magnetic errors when taking off next to the vehicle on the ground within 5 feet or so. I never spent much time experimenting, but for sure noticed this in the past.

Hopefully the difference was from the mobile device compass and not the AC.

I haven't yet, was looking for a magnet and then....duh! Refrigerator! I just checked it as we are texting, And YES it is magnetic! A pretty strong pull too. I have been trying to figure for months why the Radar view and map was always of a little bit until it flew.

Is you bed Aluminum?

That seems like a poor choice of material. Which pad are you using?

No it's a 1990 GMC.All steel cept for the toolbox which is .

I'm not sure... bought it a long time ago. Orange on one side and Black on the other. One of those foldable ones that pops open. When the weather gets better I'll check everything out and post what I see. It will be a couple really short flights with and without the pad.

I'm one of them. Wouldn't hover anymore, so I purposely aimed for a tree before it decided to fly off out into the ocean. Tree kept it, though I did have to climb a tree to go get it.

Good point. That’s what I have. Maybe those foldable ones are a better idea.
My biggest problem comes from the rebar in concrete. I shoot a lot of architecture, some with acres of concrete.

There are foldable ones. I’ve not seen one in the flesh though.

I'm using the XBERSTAR Double Side Day & Night Foldable Apron Landing Pad It looks exactly like a few other brands out there. I have researched a few of them, but they never mention the steel ring as a material used in manufacturing.

I'm thinking about replacing the spring steel with a tent pole. And don't try to steal my idea...ha.
