and I want one with batteries included. LOL ,as a motor or 4 motors. That's 5.2 megs at the same weight (power train)as the most advanced super car (Bugatti) with 6.970 times the hp.(batteries not included)
I was thinking for test only . stanless is good at cryo temps like 304 . the motor shaft could be a problem and be replaced with stanless .the only problems that I see is that most metals become extremely brittle at -300, and getting enough compressed gas to run for any distance cheaply. LN2 is rather pricey.
