I like to alter that saying a little for derby racing - Fast is as Fast Goes ;D

I might add that... from a physical standpoint, it is also unstable since once the cart starts to tip, the CG rotates around the axle thererby moving the CG further and further back. It's like loading a boat deck until the CG is above the center of bouyancy. It would be difficult to right the cart.
May none of us ever have the same issues with a little wooden car...

Wow! what a concept! Have the COM in front of the front axle so that the car flips over forward gaining 7" . . . . . |

Actually I want to try this for the "scouts entertainment" during a "dead" time at the race. I was thinking of a car that the COG would be in front of the axle on the slope but move behind on the flat to pop a wheelie for the rest of the race. I figured the best way to do it is move the rear axle forward and play with weight that way.
Should make a good video! ;D ;D
Man, with that thought, I need a life.....

Running on the two rear wheels only, it wouldn't be fast, it would only be "half fast". ;D ;D
But all seriousness aside, what you suggest is possible and easier to do if you put the CG high on the car... and put a cheater wheel(s) behind the rear wheel.
It would be quite a specticle.

HERE IS ANOTHER PIC TO CHUCKLE AT........  SOMETIMES,.......HUGGING THE RAIL IS NOT THE BEST CHOICE......KNOW YOUR TRACK WELL. (OF COURSE - THE REAR WHEEL RUBBING IS REALLY SLOWING THIS CAR DOWN) |

Joker, You're on a roll when it comes to center of gravity problems. This is only speculation, but I would suspect that the main problem was a loose nut behind the wheel. As a wise man (greenhorn) once said,"Stupid is as stupid does " Phil |
