Mine also extend 1/3 of the span as well, and the control horn is connected (usually sandwiching) the joiner, so that the force isn't totally on the glue joint.
Thanks for the info. I thought it was a bit small looking. Since the construction is so simple I may just start over with the elevator. I was thinking of making it and the rudder a bit bigger than original anyway since this will likely get an up-sized power system to turn it into something to goof around with.
