Running speed pasion 21.5, on med sized carpet track. I'm close to speed of 13.5 4 cell with a little lacking low end power. temps 140-150 range after 5-6 min.
Thanks for the quick response Vern. Now I can at least practice from square one instead of hunting for it.
64 p, 92/40 (or 110/48 if it fits), FDR of 2.3, rollout 2.98 inches/75.59 mm
