New brushless Erevo Speed run

[JerryF504]

I just measured my tires. They're 6 3/8 inches tall and are very soft. They balloon a lot so maybe they are getting some extra gearing from there also. I had to rob my front diff for a converted Sport Maxx so maybe being 2 wheel drive helped by removing some rotating mass. I also was wondering how much the kv actually drops with a load. It's rated for 5000kv but I was figuring it would be closer to 4700kv. Even at 4500kv I get 47mph on Brian's speed calculator with just adding .5" of tire ballooning. I took this system out of my E-Maxx because I bought another MMM so I can't recheck at the moment but I will when I get some more time.
