I made my old Delta Villian an air powered car once just like that. I still have the motor mount for it. I also made a small electric swamp boat too. Those are fun on ice and snow, but pretty slow on the water.
Powerful swamp boats (like the .46 nitro) are fast though even on water
I might have to get mine running again this winter... but if I do the car again it's going to be a turbine so I don't have kids running around missing a finger or two. I have a scar from an airplane prop.
