Another 1/8th Buggy Recommendation

[GeeReg]

I've read through a lot of threads, but most only discuss trucks and such and not converted buggies. I am thinking about converting my Duratrax Axis and just wanted some ideas. I think I want to stick with a Feigao motor and 9920 controller. For the motor I am thinking the usual 9L, 10L or 7XL.

I plan on 12-16 cells. I want this thing to move...fast. Somewhere around 45-50 consistently and comfortably (leaning towards 16 cells for that I assume), not geared for a top speed run for 2 minutes. Is that being realistic with those motors and cell count? :W: If not, what am I looking at in terms of speed?

Long runtime would be nice, but I realize there is a tradeoff. Anything around 10-15 min bashing would probably keep me happy. Is that realistic also?

Thanks in advance.
