these are both basically dave patrick planes and build the same. I owned the pitts and loved it. it landed and took off so sweet it made you look like a pro. I mean you could have went up and just flown the pattern and then landed and had people talking about what a great job of flying u just did. it lands that sweet! Technically i think the ultimate is supposed to have less coupleing issues and such but in my opinion go with which ever one u like the looks of best. My opinion again the ultimate is ugly, Im not a fan of orange.
