I'm still not clear on why. If you're saying we need to go slower, can't that be accomplished with slower motors and battery limitations? If you're saying we should do it to embrace newcomers, then we need to start by reducing the barrier of entry into competitive racing with all the extra crap people feel they need.
Maybe I'm blinded by the light, but this really does seem like a desperation move to keep NiMH and brushed motors relevant. I'm sure it works okay, but again, why this? How is this better for newcomers? They're still going to feel like they need mountains of crap to be competitive after a trip to the track, surrounded by guys with mountains of chargers and other bloated gear.
