I have a mad rat rtr.
You'd need to ball race them - £10
The brushless rtr is actually pretty fast, the servo however makes an acoms as7 seem fast!
You also have to spend a lot of time on the gearbox to free it up when ballracing it. The idler gear has to be filed down and some plastic taken off the gearbox to make it work well.
Next time Im down I could try the car on standard tyres to see what they're like.
As this is just a bit of fun I think mixed teams with own cars would be better. Take a look at the 24 hour thread for an example of the issues that using a spec car causes.
As mentioned above the less rules the better. Less rules =more fun!
