Yesterday was the maiden flight of my UCD. After 5 flights I noticed the top rudder CA Hinge had torn in half. I have read Mike Buzzeo's How To column on Installing CA Hinges. I installed the hinges using his method, but the hinge still failled.

The UCD rudder is too large of surface for using CA hinges. I was doing knife edge loops, and many different spins involving Maximum rudder throw in flights 3, 4, and 5.

Has anyone had success using CA hinges on the UCD when doing ratical manuvers involving maximum control surface movement ?

This has been one of the funnest planes I have flown!!! I am just bummed about needing repairs already.
