The CMP .50 size Zero is a good flyer, but it has very high wing loading. I tend to land mine a little fast, adn hopefulyl at the end of the roll out, not end up on it's back. Moving the mains forward to the leading edge has helped, but on rough field, sometimes it's not enough (even with high rate elevator). The short nose meant a lot of weight on teh firwall to balance it. But bottom line, I really enjoy mine.
