MM5700 Gearing

[Nick]

Mambamax 5700 in a T4, with a 81t spur.

1) I will be using 7 cells at first, what pinion would people suggest for a "mid" balance.

2) 3s lipo, mid balance again.

When I say mid balance, sort of not high geared and not low. :)

What would you say the low-high range is for pinions on both battery setups to?

Thanks,
Nick.
