I don't want to get into the "You gotta have a big plane to be competitive" thing. It has been beat to death. But when you talk about size limits you have to remember that all you will be doing is excluding another group. Now the guys with the smaller planes feel excluded. If you set size limits you will be excluding a large group of guys that already have big planes. I promise you that a HUGE portion of the 35-40% planes sold don't go to IMAC contests. There are a lot of people that have these planes that can be attracted to IMAC because they can fly the plane they already like and have, as compared to pattern.

Just my thoughts,
