Container cargo drone I made a while ago
Intended to be used mainly as a container loading/unloading/staging vehicle (it's not fast)
The idea is that the drone itself is the size of a standard container while not in use, with the standard top/bottom electric connectors
So it can easily be transported eg. on your boat/train alongside other containers
Controls are labeled on the seat/buttons (though it's not super polished)
Make sure you unfold before trying to drive it, and I highly recommend turning on Heading+Altitude Hold
