I might add that a 13.5 w/timing class would probably be well attended at, say FW and other clubs whose base is made up of more experienced intermediate racers. This would give some of the mod racers a second class to run and some stock racers would run it as a second class also. The down side is if the mod numbers aren't strong enough you could very well weaken the class turnout. The 13.5 w/timing is the most logical class to add if you have to do it. This no timing issue doesn't make sense, if you want to slow it down do it with less motor, much easier to do.
