those are impossible, unless you just want the emitters. If so, use emitters... Blockland doesn't use physics in everything, in case you havent noticed. And, I'm pretty sure it would be pretty impossible to add thrusters and hover balls and such to vehicles. Remember, although Blockland is scripted pretty good, G-mod took a whole group of people to create, and they were in contact with Valve, another great company. You must either be new, or randomly found these forums to start posting in. No offense.
