OK - here's the regulations sent by Giovanni. They are fairly simple and basically you can only use Thunderslot parts.
I am still waiting for absolute confirmation from Terry at Gaugemaster as to how many drivers can qualify for the final - He initially told me that simply entering one round will allow you to race at Gaydon, which I personally think is a good idea, and I don't see why this will change.
At Nascot Wood we will do 6 heats for each driver, but best 5 to count. These will then place you in finals - so in theory if you qualify last, you have an outside chance of working your way up to the top and winning. Obviously other clubs might have their own system.
I have also been told that there will be good prizes for 1st, 2nd 3rd at each round.
