I don't have much success with RCU's search engine either.
While I feel that the UCD 46 is a better 3D flier than the UCD 60, I have found that they are both lousy harrier machines. The UCD 46 will harrier within very a narrow band of angles of attack and throttle settings but can easily be blown out of a harrier by the slightest breeze. That's why I never attempt a harrier at low altitude. On the other hand I can harrier my Cap-X all around the field and land from a harrier and it's a heavier airplane with a higher wing loading. When it locks into a harrier it seems almost safe from a snap. Is it that heavier planes are easier to harrier?
