Dave, I believe an event that fits your description was approved with the last round of AMA rule changes. It is called Open Scale and the rules are on page SC18 of the rule book. Basically sport Scale with no builder of the model rule, ie., static judging of purchased or ARF models. I'm curious if anybody has run a contest including this event.

My comment to the scale rules board whenthis was proposed was that if they passed this set of rules, they could simplify judging by having contestants present their cancelled check as documentation and most $$$ wins.
