The age old arguement. Back in the day these events were ran over 2 days. Classes were supported, then over a period of time numbers dropped off so these events went back to a one day event.
8th scale EP IMO needs to stay on 8th scale tracks. As pointed out earlier some 4x4 SCT are 8th scale buggies with SCT shells. Not all track 'volunteers' who maintain tracks for 1/10th vehicles want their work destroyed by overpowered inexperienced people.

end rant.
