I love my Flip it's a real in your face 3D monster. However the UCD 46 is much better flying plane than most people will ever know. It maybe be one of the best 40 size ARFs ever designed. It will do a nice slow roll or 1 roll rolling circle or a knife edge elevator or loop. Most importantly is just feels right and looks good. It's not good at stall maneuvers but for a the average weekend 3Der it comes as close to doing it all as anything I've flown.

Every plane has its limitations but some planes are just so fun to fly you don't notice.
