Seagull models(distributed by Horizon hobby, I believe) has a 90-1.20 size ultimate that a 20cc easily fits in. I my self have been waiting for a true 30cc ultimate as well. I see that Goldwingrc makes a 30cc ultimate and Pitts, just hard to get any info on them. Right now I'm starting on 1/5 scale Waco from Kangke models. So far, it looks fairly nice.
