There was no "tone" intended. Just stating facts is all.
Tight tracks or Lesser traction seem to be place for the Light motors. With carpet racing the cars are fairly on edge, with very short sections of the track, or in the ICC, some tricky carosel type corners. The motor being smoother or softer from the bottom to middle, makes the car "easier" to drive.
Steve hit it right on the head.
It's not really about being better or worse, it's just something that is different.
As good as the Pro's are, you would be surprised how many of them don't practice much. Or more accurately, don't get to practice ALL the classes they race all the time. So when something changes, or is new to them, they have limited time to get used to it while the pressure is on. Having options like this are simply ways to make things happen "easier" or faster due to the limited time. Somtimes, Slower is Faster.
Our Light motor is kind of like the "half turn" motors some of the other teams have been using, it's an in-between power level.
The L motors when compared directly to an R motor are basically "softer" from the bottom to the middle of the throttle. It may or may not sound bad, but they simply do things slower then the R motor. Again, sometimes slower is faster.
