Rules for the Concept Car Challenge

We have a few venues to chose from...

The real question is when.

My thinking is that the 3rd annual SoulBoxer Invitational held in July will be a good place to throw down.

Maybe we can get a few entries with that amount of lead time. 

So I know the bearing used by most cars is standard but have we considered 1.5x4x1.2mm open bearings? I know they are not flanged so your assembly must have some sort of fixturing to ensure parallelism but due to the smaller rotating mass and bearing, they might be faster.

Uuummmm.... sure... sounds good.

obviously, funny front wheels crafted for a specific method of steer will be allowed regardless of what they look like. pinewoodcnc

Agreed.

Let it be noted for the official rules that the word “funny” should be stricken from the record. 

Hey Ballwasher and Ballwasher’s apprentice,

Just so you know what this contest is all about... 

Here is the definition of a concept car in case you two are curious...

Soooooo....

dont think that because you might win the race with your POS 3D printed plank car that you are entitled to shit! 

Because you ain’t!

The race is worth less than half the points you dumb shits!

This is going to be extremely difficult for you to understand since it is a little beyond the binary competitions you dumbasses are so fond of. 

so you better plan on bringing your “A” game to this challenge. Just send in! If you have a set between the two of ya.

I believe this is the best class for our concept cars to run in.
