Aside from that I'd go to IB cells, as they seem to be the ONLY CELL for 12thscale.
In my last run I did gear up to 55mm and it was quicker at first, my fastest lap was over half a second quicker but it seemed to go soft earlier, around the 5 minute mark. So is this just a case of tired cells?
Unfortunatly IB cells are not legal here till April 1st but I will be getting some 4200's then.
