*NEED HELP ON GEARING FOR HPI RS4 3 EVO?*
We run on a small to medium size trake. It runs on the hot side. It has no low end punch. I believe the gearing is for a large track. Ran it at a series race and the temp was fine(large track). Everyone said it needs the gearing changed. No one runs an HPI out there. Can anyone help me out? The spurs are 47/43 the pinions are 18/22.
