Wanderer or Feigao

[spymaxx]

I finnaly sold my basic xl3100, to fund some more upgrading. My emaxx has all RPM stuff, MIP bones, Maximizer diff cups which puts it in the 12-13 lbs. range. I plan on going to either a Wanderer or Feigao 9 or 8 something with a strobe slipper. Which motor would be best running on 12-14 cells? I have several GP3300 packs now, but will buy 14 cell packs next time. Also, what pinion tooth would I need? I want to run in the 40-50mph range. i do not race but may. Have stock tires, and I will try to go convert to the single speed trans, depending on how much $ is left over. Also, I already have a Warrior 9920 controller. Future plans include G-Maxx single spped conversion w/ steel idler, G-mass G2 carbon chassis.

Thanks for the advice and education!
