RCU has an online review of the UCD with some videos.

Mine's got a Saito .91 in it with an APC 15x4. Hitec servos all around - 425s on the ailerons, 525s on the elevator halves and a 5625 digital on the rudder. All controlled with a Futaba 9C. Central Hobbies carbon fiber pushrods, flying wires tieing the stab to the fin and bottom of fuse, and fillets on the stab to fuse junction(top and bottom). CG at 5-1/4 from the LE. CA hinges replaced with Dubro pinned and I'm also using a Du-Bro quick-fueler valve.

Only have 3 flights on it, the weather here has not been cooperative at all[:@] So far I'm pleased with how it flies.
