[quote]The motor that runs closer to 40000 rpm will be the most efficient[quote] not true. You can't compare an L with an XL, they are different motors. It depends on the setup (gearing etc) which is the most efficient. If you want to use a MGM instead of an 9920, the 16160 should be the one.

As coolhand mentioned, the 9XL would do well on 12 cells. And you have got the ability to step up to more cells. But why no 7XL on 12 cells?
