Yeah, and with the fairly high weight limit and short matches, there's really no design crunch to move to a more expensive/efficient motor. Although you're right, FIRST doesn't even allow teams to use brush motors that don't come in the kit; if they let teams buy comparable brushless you would start to see even more of a gap between well to do and not so well to do teams.


You make a very interesting point about the motor coefficients, too. Moving to brusheless opens up a lot of design parameters to which students don't currently have much exposure. Picking motors based on their performance and fit with your design becomes much more complicated and interesting.
