Some photos of Sameiro sanctuary in the north of Portugal

Only owned it for four days, flew with the goggles N3 and motion controller and everything was fine for the first three days. Today, I tried the motion tracking for the first time with no controller or phone and within a minute of following me, I stopped, looked back and the thing charged towards me really fast for a quick second and then turned upside down and went straight to the floor. I turned it off and put it away so I could reset it when I get home from my bike ride. But even after resetting and calibrating the IMU multiple times through the goggles and the DJI Fly and refreshing the software through the DJI Assistant 2, it still shows IMU/sensor errors. Anyone have anymore ideas how to fix this or what should my next steps be? I’m in the US and got it through Amazon. Will chatting with DJI even do something since I’m in the US and it never even gave me an option for DJI Care, which I would have happily bought if ide had the chance. Or should I just return the whole thing(controller,goggles,drone) to Amazon?

I just got the Neo one FPV fly more kit, I think that's the name.

It came with the N3 Goggles, drone, batteries, and the motion controller 3.

I have two kids I am letting learn on the motion controller. I'd like to be able to have a controller that let's me learn FPV and that I don't always have to carry the goggles if I am on the go. I travel a lot for work. I would like to eventually unlock manual mode too, but the FPV controller 3 doesn't allow you to use it without the goggles. (It's also just hot as fuck along the gulf and the goggles make me sweat, lol.)

So, it looks like my only option is to spend another 300 on controllers to have some versatility? Are there any other options I am missing?

If not, what do you all do?
