mamba max pro?

I would suggest the MMM esc since this is a full size MT, but if you want tamer power then go for the 1800kv 1512 NeuCastle motor- less driveline shredding torque than the 1515 2200kv motor but it will still be powerful enough to be fun on 4s lipo, or lots of fun on 5-6s depending on what you want to achieve exactly. Other motor choices would be something like a feigao 9L on 4s lipo, or a neu 1512/2.5D/F (2050kv)- there is a sale on at Neu at the moment: http://www.neumotors.com/store/page10/page10.html

1512/2D/F (2550kv) would be a bit more speed, though you would gear down a bit more to generate more torque- keep it pegged to 35-40mph generally.

would you run the 1800kv 1512 NeuCastle motor on a mmm, or mm pro? i see the brushless emaxx uses the mmm combo. i plan on running 4s lipo as you said. any idea on run time estimate? this will be my first brushless build, are the newcastle motors waterproof?
