i'm building my CP right now, i have everything i need except a spinner, going to use an ultimarc spintrak, father xmas may bring me one
but i need to drill the hole for it now to work out the cp graphics and route the holes in the perspex (when i find some for a good price)
i think it's a 28mm hole, but want to double check with someone who's got one and fitted it before i drill a hole the wrong size in my cp.
