Hmm. On anything up to 4s, the MM is probably the clear winner as far as the ESC is concerned, although I'd probably get the MMM just for the potential to go up to as high as 6s if you wanted to. It's just a matter of picking the motor wind to match the voltage.

Even though the Slayer is supposedly lighter with smaller tires, I would be careful on voltage/motor selection. Much of the decision is based on how fast you want it to go and if you are keeping the two speed tranny.

- Speeds ~35-40mph using 2 speed: May be OK with a 50mm MedUsa or 1509 Neu or L Fiegao. I'd use no lower than 4s to keep current low though, but may be OK with a decent capacity/C value 3s pack.

- Speeds ~35-40mph using single speed OR speeds >40mph using 2 speed tranny: I'd step up to a 60mm MedUsa or 1512 Neu or XL motor. Again, 4s minimum IMO.

- Speeds >45mph using single speed: Step up to a Neu 1515 and increase the voltage to 5s or 6s. That extra high speed load on a single speed tranny will need torque to move.
