Mike,
There was nothing wrong with your question mate, unless you know what
UK tracks are like you would think its hard to set the car up for various surfaces. We just make the cars work over here, the kit setups that come with cars are useless for uk tracks
Try the losi pistons and oils i suggested, it has already been backed up by daz on here i think and im sure you wont be far off.
US drivers dont really understand, over there its like racing on road with jumps and they go home when it rains
