The batman/joker spark set is currently £85 at John Lewis (or Amazon if you prefer) so I have taken the plunge as I wanted a bit of sport track for testing cars for proxies. This led me to wonder can you use spark to run a car at a specific speed/voltage endlessly for the purpose of running in a car/tyres?

Easy way to do that is to open up a set type controller and remove the spring so that the trigger can be set to a position and it will stay there. Best to make sure you identify that controller clearly though !
