the tank connects to the carriage with it's connector. But it works with regular landing gears, too.

I see there are connectors on the monorail cart that carries the vehicles. Does this mean that the vehicles connect to those or is it landing gear, brakes, what?

Hm. It's a bit more complicated, I guess, because I don't have a final solution for the mechanical part, yet. I will make a more detailed video when it's done.

Ahah I see. Does that act like a gimble as well?

There's some kind of mini-monorail on top that drives forward and backward.

Interesting, how does it move from side to side?
