My experience, basically:

3s LiPo - 32P gears

2s Lipo - 48p gears

FWIW. There are lots of variables that enter into this. But, this should work as rule-of-thumb to get you into the game. Of course, you are aware that gear ratio options are much wider for 32P than 48P. This can work to an advantage when initially tuning a car to the strip. Then going to 48P for final gear ratiofine tuning. If finding you must stay with 32P; then tire diam. becomes a crutial element in overall striptuning. At least thats the way it works for me.

Caveat, of course. There always is one. For my 1.80sec Index SuperComp rail, I run 32P, even with a 2s LiPo. Insurance I guess. For my 2.50sec 2s CompElim rail I run 48P exclusively. Both are options to consider. Just have to sort out which or what works best for your application.

Hope this helps. Good luck.
