Sure it's hard to to tech all this stuff. But at my club I'm trying to just go on the honor system. Another guy and myself were running the 4300 with the endpoint turned down to 75%. The racing was very even against 27Ts.
Doesn't matter though 'cause it a brushless. But here's the irony, they don't really tech anything. Even though we have a weight rule, there is a guy that we all know is under weight, but he is allowed to run. Hmmm....
This is the same guy that does not want to comply with a TakeOff 27 tire rule. And if he is forced to, he says he has a special chemical that will turn them into shore 20. Jeez.
That's the problem. Alot of people are willing do everything, including cheat to have an advantage. They don't want to play on an even field. Brushless will even some of the playing field (despite what Trinity says) and the old-timer motor gurus will lose some of thier advantage.
