A LiPo option for 12th scale would defiantly get me back into one. 12th is my favorite carpet class but with no local tracks to run on I just can't justify the battery cost for only a couple regional events a year.

It's true, and it was a 7.2v NiMh pack from a 1/18th car. The Mamba worked brilliantly on this voltage, and the car was, as you say, about equivalent to a 19T.
The car now has a LiPo 7.4v pack fitted, weighs about 500g, but I've not seen it run yet. Brian has the same idea as me using a DB12R, I think!!
Imagine a 12th car where you never take the cells out, do limited maintenance on the motor, and get the sort of speed that takes ages to get from a 19T/NiMh combo - and we haven't started to tune it yet!! Add in limited wear on everything from the 40% lower weight, and less breakage (and longer lasting bodies!) from the lower inertia in a crash...
05 motors aren't essential for 12th, and 3.7v simply makes more work from having to fit receiver packs, regulators, etc. 7.4v LiPo with Mamba makes it all much simpler and more fun - what's not to like??!!
