And while we're at it, somebody once mentioned that a REGULAR dual cell will outrun a Layman's dual/tri cell because of the higher current and more torque. Is this true? If it is, then watch out ActofGod, because people may be reverting back to the old method!!! -jk

im not sure but i think it has to many teeth on tha outside and on tha inside, but to make sure youll have to talk to Ahh5hit, Tiny or Numanu

A fet modded single cell will out run them both, especially up hills.
Massive torque increase and speed too.
