If everyone is having fun then who cares? Look some folks will want to run the Lipos. If they can get a class together go for it. If some folks want to run Trans Am.....go ahead and have fun. If others want to start a spec class using 4 cell then by all means get one going.
If we all sit around and pontificate about what class we think the whole world should run nothing will start AT ALL.
Get off your tail and go race!!
