Jarrad: I don't own one, but want to, and have been reading every tidbit of information as it becomes available. I think you should be fine with no BEC. The reg in the MMM is switching regulator anyway, so theres no efficiency gain, its just a PITA to remove and replace the red wire in the ESC lead everytime you want to look at/change the programming.

orfre: In a buggy I reckon it'd be fine to do that mod - in my HB Lightening 2 Pro I run a stock standard Mamba Max (brand spankin new, just got here today) on 4s1p A123 and a 3000Kv L-can $25 inrunner geared 14/46 and it doesn't get too warm

Are you sure they were running 2s2p. A 2400kv motor on 2s geared 12/46 will be barely crawling! Maybe two 2s packs in series making it 4s1p? Sounds like a much more ideal setup.

Anyway, the point is that in a Revo or other Large vehicle there will be a lot more stress on the ESC, I'm not sure hacking up the case and running without a fan in anything bigger than a buggy is a great idea. Maybe if your running 6s exclusively it would be OK.
