When converting from 4cell NiMh to 1cell Lipo, most people will have to re-gear to achieve a different rollout. The general formula is to add about 10mm for the same motor for this conversion. Eg: For a 10.5R motor: 4NiMh set @ 50mm then 1S Lipo will need to set @ 60mm.

Now my question is why?
Is it because the car is lighter, so that we can re-gear another 10mm of rollout without an increase in motor temp?OR
Is it because the voltage is less, so we need to increase 10mm rollout to match the speed of a 4cell car?

Sorry I am a little confused on this. Can someone please explain to me on this? Thanks in advance!
Its because the power is slightly lower (even with reduced weight) so you need more gear for the same speed...
