Just wanted to let everyone know I flew my UCD for the first time Sunday. Awesome plane. I'm a newbie at advanced aerobatics, but this is a very stable plane that I immediately felt comfortable with. And what a floater! It doesn't want to land. I'm running an OS .91 Surpass with a 14x6 APC prop. If I went to a 15x6 or a 15x4, what differences would I see?
