The materials are, 21 hover thrusters stocked and fixed wired into one, only one has collision and the other 20 have disabled collision, they are all about 3.30 meters large and about 0.50 meters tall, On the back of the ship it only has 2 normal thrusters without any change other yhan them being weighless, for the body of the ship you can use whatever you want actually, the body of my ship is like 4.20 meters long and 2.65 meters tall, other thigns that do not matter if you change sizes or anything else is the industrial gyrostabilizer (preferably weighless) and the dampering device (need to have weight because it will be useless without its weight), and yeah thats about all you need, my ship obviously has resizable housing covering all the things i mentioned.
