I did a search and didnt find any results.. have any of you guys tried the parts from a K.I.T. racer? They use the exact same drivetrain, and had many different options (gears, tires, motors, heat sinks, etc..) They are not R/C or controlable, it basically has the battery straight wired to the motor.. so they scoot around pretty good.
Here is a link to what im talking about

Most everywhere that sells them have discontinued, so normally you can pick them up for dirt. I picked up about 15 of the cars and 5 of the test tracks next to nothing at Target a few months back (before i knew about microsizers) If you get the test track, you can setup an oval to speed test your Bit or Micro-S.
Ill take pics later on to show the guts of one of the cars, and verify the axles are the same width.
new member btw.. cool board.
