Thought I would post this just for kicks My OLD CAT is a 1949 D8 and believe it that monster purrrssss like a CAT. Has a pony engine to crank the main engine a D13000 that tops out a 1200 rpm and top speed around 5mph, it can get alittle busy in the cockpit at times , thats why it has a family seat, dont think it would float either weight around 70,000!!!! JUST FOR KICKS
