What pinion (spur) should i be using on a 4.5 losi motor in a kmc zx5 on carpet. i decided on a 14 tooth pinion and a 76 tooth spur (working from the losi gearing chart) and gave it a run up and down my road for around 5 minutes at all speeds as if i was driving on a track. it came it only just warm so i think i could go up a few teeth.
but what do you lot think would be the best pinion (spur) to run? (as i have no expereince of running on carpet) without it getting to hot and damaging the magnets
