These motors are certainly a different beast to what's in a standard plastic slot car. Even at the RTR entry-level end, like the Parma 16D in my Flexi -2 chassis below, they'll be pulling a good 3 amps or so...

   

There are two BSCRA clubs in our part of the world that run motors like this - Roedale in Brighton and South Downs in Barnham. The motors are fitted into a range of 1/24 and 1/32 metal chassis, topped with lexan bodies. There's a good resource about motors on the BSCRA website: www.bscra.org.uk/motor
