Our agreement is 4 AA rechargeables (1.2v), stock motors, standard width and brand rubber tires. Any setup changes with differentials, suspension, alignments, gearing, weight distribution, are allowed. For gearing almost everyone ends up with 11T pinions for MRS4s and 19T on the M18s.

The spirit of our racing is for the drivers to be able to do whatever they need to do within reason to make the car handle in the preferred way, but not try to do all kinds weird stuff to gain a power or grip advantage on the other cars. Then from there it is all about the driving. At this speed there are 5 points on the track where I normally use the brakes, and there's lots of sliding and drifting, so it is plenty fast to be fun. There's 3 rises on our track where the cars get light or even airborn and 2 of them are in the middle of turns.

We could use 4 2/3a cells that is true. It would be a little lighter and give the cars a bit more acceleration which would be ok. But then we'd have to change batts a lot more often. As it is now we race for hours and change batts once, and one some days we have gone all day without changing batts.

I have tested with a speed 300 motor and a really low gear ratio and it was a blast! But, that was driving alone. With 5 or 6 cars on course it is challenging enough with the stock motors. Maybe one of these days we'll have a no rules race and just see how wild it gets.

We just got 7 more of these bodies so all of our racers can create an open-wheeled car.
