We had a play with them at Bury a couple of years back. Echoing the comments of others its clear they really don't work well on tracks built for 1/10th cars and are a serious hazard to marshals used to 1/10ths. Likewise current 1/8th clubs might let you run there, but the majority prefer engines.
They do seem to have seriously caught on in the Basher market though, as a good 1/8th electric offers insane amounts of power in a tough, low maintenance, neighbour friendly package. That in itself means that the class has a real future - though where and how I can't say. I suspect the 1/8th nitro boys will see it as a kind of beginner class, learn how to drive first in electric then later learn engine tuning and go nitro....
