There is also the chart that shows different windings/kv ratings & size etc on the main Neu website:
CLICKY.
When you say light MT, how light roughly (could do with a link/pic really for my brain to mull it over), whats the intended voltage, and would you like to use the motor in something bigger one day, or just for lightweight stuff? The 1515 motor is generally used in the E-maxx, E-revos and 1/8 stuff, so you may find it is a bit too much torque/weight/size for a smaller truck. In which case the 1512 is a good choice (winding to be determined after prior questions are addressed)- it too is also used in lightweight Emaxxes since it stil has alot more grunt than a HvMaxx; Neus are truelly versatile motors.....
