I understand completely Geoff, and no doubt I would be annoyed if I was on the receiving end, but I just see an outright ban on rotaries as restricting them simply because they are too quick/win too much, very similar to what occurred in the early 90's in other classes of racing...
That, and I'm a rotary man at heart (have had a series 2 RX7 and an RX3) and plan on an FD when I've had my fun with the 180
I like Harry's rules, don't see any problems with them. The only one I'm not a big fan of is the brake restriction as this will make a few models unable to compete (ie S13) as they had such pathetic brakes from the factory. My 2c
