Grass track,1/8th scale,the winter series required the full spike tyres just to get any forward momentum due to the mud.Now,even though the track has dried out,I find I still need them,as the surface is quite slippy,and loose in places.I'll need to get up and see this new track that you're building at Stonehaven,at least it will be shorter than 276m,and not take the better part of a minute to do a lap.
