Thanks for that, I'm running a 10.5 HPI at the mo because I already had one.
As for addative, put all over rear, 1/2 front about 10 mins before a run. Not going to bother changing srings battery position, or any of the other stuff just yet because after running 1/10th TC for the past 15 years its nice to be able to plonk a car on the track and have it go pretty much where you want it to go straight out of the box Might need to review that statement after the first race though

Deffo going to invest in a box of these http://www.ace-safetywear.co.uk/stor...wipe-250s.html
