So when I used to run a receiver pack in mod to speed up the servo I was cheating? Better yet all the big names that did it were cheating? Some of us were running 6 cell receiver packs at the end of the brushed era to get the servo's faster. Were we cheating? All that big power feeding back through 22ga wire must have been such a big deal. Give me a break. And for the boosters, it would take a booster the size of a speed control or bigger just to get to the point where we start to send much power to the motor. Give me a break. I won't even try to explain how a FET works in the speedo circuit but you might want to do a little research...
And for the slower class. What slower class? Seriously. This is a 12th thread so what 12th class is there that's slower than 17.5? Are you suggesting that they run Mabuchi's? Do we need 4 classes of 12th? Give me a break. You can still run 2 "fast" classes at big races if we have 3 so it's not like you can't race a "fast" class.
