I'm tired of thinking about all of this. I need this thing to go fast. It was pretty fast as a nitro, and I need it to be faster. What would be the point if it wasn't faster? I'm thinking that I'm going to go with a 9L. I could be wrong, but common sense is telling me that the 7XL is too much motor. The lower wind motor is going to give me less runtime and less speed. The 9L on 4S will spin at about the same rpms as my nitro and if it will run cool with a 13t pinion, then that would put me at a good starting point. What I mean by cool is within spec.

If it overheats on the above setup and I can't run it the way I want to, I'll just go back to nitro.

There's one thing that I don't understand about these brushless motors. That is their ability to generate torque. Does the torque go up as you reduce the number of winds, or is the ability to generate torque a constant among a line of motors? I mean, do all L can motors generate the same amount of torque with the number of winds affecting only the number of rpms/v?
