Stampede...
Either brush up on your mathematics and work out a sensible ratio yourself, or use trial and error. I'm sure we're all pretty sick of reading thread after thread of you requesting different ratios for your endless truck, motor and gearing combinations. Julius. |

Just try any combination out. If you smell burning then stop and gear it differently

Its the gearing ratio:
SPUR / (divided by) PINION X (multiplied by) INTERNAL RATIO (you'll have to find this out, it will be in the insructions, should be 2.5 ish) |
