Nice unique vehicle you have here! I like it!
Saw your thread on Reddit and many good suggestions there for future enhancements (as well as what you've listed here for planned features).
One suggestion I have is to allow the thrusters to push left/right in addition to forward/back. Looking forward to seeing your progress!
This is absolutely brilliant! Very controllable and stable, high quality, and extremely fun to cruise around the islands of Italy with. This would make a really good platform for a houseboat mod of some sort.
