I ran a couple of tests, just for fun: first one, cfg edit of the turbines, 400 each. I _think_ it\'s impossible to go up to 300m/s with the cart, as I managed to get about 280m/s (almost full power, too) before a small jump ruined everything. Second test, water speed record! lol. Took off, auto landed on water (upside down) and started running... 21m/s and at about 22 it pointed down and turned into a submarine O_O\'
