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:

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.
