Switching to 540s is more logical than making a silly rule for one segment of electric.
Instead of asking everybody to buy new batteries, motors (to move up form stock) chargers and such, create a slower class with a slower motor. This way every car, charger, discharger, whatever still works in every car, 6-cell can still be used in RTRs, off-road and with normal people.
Creating some change because Europe and 12 people in Florida throw winds on a back straigh of a gas track is insane. If you run carpet indoor learn to drive so you don't crash. Saying you throw a wind on a big track is the equaivalent from over-reving you real car for 3 miles and thinking it won't blow. If you're going to gear a car for the back straight it's going to suck on the rest of the track, if I ran nitro and reved the engine down the back straight in 1st, the engine would blow, it's why there are 2-speeds.
Motors blowing up is NOT a problem for 95% of the industry and racers. "speed" isn't to fast, most people just can't drive. So rather than making everything change for things that don't exist. Start a Silver can class.
But to make it more appealing instead of those ugly motors, design them to look cooler, lock the comms, throw some blue LEDs on them, and poeple will race them if they want.
NOBODY asked for this rule change, so there's some other motive behind it. Is it brushless motor companies starting rumor to help kill brushed? To help stop LIPO?
But this change is an emxpensive and shortsighted thing to even think about.
RACING was more popular year ago, because we didn't have 300 classes to divide racers.
