Yep, my UCD broke a CA rudder hinge on the second flight. But I used a pull-pull rudder, so I figured it could have been my fault.

Then on the fifth flight I broke a CA hinge on the left elevator. Engine is a ST 90, and my control throws are only slightly more than the instructions call for. But then again, the UCD was designed for 90 size engines and 3D throws, right?

The rudder now has four Klett 1/4 scale pinned hinges and each elevator half now has three Great Planes pinned hinges. After five more flights, no more problems. But now I'm keeping a close eye on those CA hinges in the ailerons.

Despite the minor setback of the broken hinges, I REALLY like my UCanDo! The only problem is that after 10 flights, I still don't know if a UCanDo will fly straight and level.
