I do not believe the FAI rules committee will ever permit gyros in F3A pattern, but they've made other 'interesting' decisions in the past. If it did happen I would guess it would not be for at least a few rules cycles. If the AMA rules committee allows gyros in pattern without it happening at the F3A level, I think that would put rising US pilots in a quandary as they would probably want gyros to maintain their competitive edge in the lower classes, but the jump, or should I say leap, to F3A will become more difficult.
