Now there's an idea.... Slot plane racing.
Had one of those many years ago.
Bought it for the kids (honest...) a little F15 and Mig 29 that zipped around a track doing loops zooms and rolls.
The bodies were held on by magnets and if you overtook you could knock your opponents body off.
I seem to remember spectacular crashes rather than succesfull combats...
Cheers
