we run 1/8 scale e buggies at our indoor track here in nashville. the rd limits the class to 2s 1400kv and it's worked out pretty well so far. we've had some big races and no one's gotten hurt. i've been hit by every other class from 2wd buggy to 4wd sct. i've recieved an award for marshall of the year. my advice is just show some patience with those that are less experienced in driving and marshalling. help them teach them
