The RPM's reached will obviously depend on the length of the straight, you'd need a big track to get the max theoretical revs...or small diameter tyres.

Indeed, and a whole bunch of other traction related factors too.

And, just to add, this is not an attempt at any kind of speed record. I have two simple objectives here:

1/ to build test-cars which are capable of reliable 10m/s, 12.5m/s and (hopefully) 15m/s performance over a 5meter acceleration lane from a standing start, followed by controlled deceleration. This is for a new digital slot car system evaluation.

2/ to explore whether, with proper design of the performance envelope, that brushless motored slot cars can perform competitively with brushed motored slot cars across a wide range of slot track designs that are currently in use (i.e. home, local club, national and international).

Maybe 1 and 2 are mutually exclusive, let’s see.
