In a buggy, Large Motor (1515) or Small Motor (1512)?

[The Dan]

For racing? Heck, I wouldn't even bolt a 1515 into a truggy. I would recommend running the 1512 in a truggy and a 1509 in a buggy. But like others have said, if you want the flexibility to go faster with gearing, you have to go with a big motor. The point I'm trying to make is that for racing, you don't want too much power, and therefore should run a smaller motor.
