I disagree, noise is a major issue in many locations, even some at some AMA charter clubs. The noise gets the plane noticed, and then people come out of nowhere to complain about it, even if it is quieter than their neighbor mowing his lawn or running a gas trimmer.

To me, planes in the <1lb class are more indoor flyers than park flyers. I'd want to see at least a 1.5lb limit. The pod & boom Aerobird comes in at 17oz, and I have a plane I built out of flat foam that comes in at about 19 oz.
