It’s not easy to guess how a new car will handle at a race. It’s hit/miss without a track.
Someone posted this and it caught my attention. It can be configured to go in reverse with the flip of a switch, and has it’s own power supply with a potentiometer instead of a hand controller. A bit crude, but it only measures 30″ inches by 48″ inches.
It would not take much to improve it for our own uses.
As a first upgrade to this design. You can make all three curves different radiuses.
Create a drag-strip beside it if you want to test top speed or acceleration.
What do you mean think outside the box? Where did you even get a box? Where's my box?
Even though I may be new at this myself. How can I help you build your car?
