There is a cube black. Everybody knows that one.
The green one is meant as a solo upgrade.
The purple seams to be a smaller one.
There is a blue one on the profiCNC store, but there is NO info on that, none that I could find.
The yellow and orange are on the ardupilot code already, but no info on those as well.
Is it all still secret, or can someone explain a bit about their differences?
