Just wondering - what kind of room size would be a reasonable minimum for Wright Stuff? (and I suppose ELG as well - excluding Helicopters because it goes upward of course) I'm curious to see how tightly planes can bank before it becomes unreasonably difficult...

it's been a while, and I've only ever practiced in gyms and large cafeterias, but I think 20 feet by 20 feet is a reasonable size to fly in. The circles probably won't be that large, but planes do drift a bit and are prone to crashing into walls when they get near.

I'd think if you were proposing a space that was much smaller than about 40' square, you would want to notify all teams well in advance, to give people a chance to trim their planes and practice for a small space. ("Well" in advance as opposed to the usual "in advance".)
