Mamba monster and two 5700kv?

If you cut your MMM very carefully, in half, you might get two Hobbywing 80A speeders out of it.....

Junkman- brushed motors have a very short life with lipos in my exp., and this includes planes, helis and trucks. Normally brushed motors pull more than they're fed with Nimh. But the huge difference in current makes lipo/brushed almost as bad a combo as BL/Nimh, me thinks. Others may have few or no issues, but I sorta doubt it.....

That is really two things at play iMO... brushed motors were fine w/ nimh because your packs wouldn't last anywhere near as long as the typical 5k lipo so you spent more time cooling than racing :) not to mention only the best nimh would hold as high of voltage through the length of the pack when even compared to a generic lipo let alone a high end matched lipo pack. So it's the current and the run times.. if you run in 7min intervals (less than 10) and let cool they, brushed motors, last a LOT longer. One other thing that happens is the brushed guys are trying to get too many MPH out of their motor more times than not and this too kills the motor quickly.

All just my opinion.. of course :)
