Okay, a couple weeks ago I had a small crash that resulted in some tail damage. The horizontal stab was not damaged but the vertical stab(elevator) hit the ground and although the actual elevator was not damaged the piece of the fuse underneath it snapped off right at the nose of the elevator. When I epoxied this piece( the chunk of fuse and the elevator) back on it was square with the rudder so after it dried I never checked it again. Well I went to the field today, took off fine made the first two turns fine but when it got out directly in front of me it started some crazy stuff. It almost felt like it was turning by itself,like I didnt have control anymore but I was able to get it back and land. We were stumped and thought maybe I lost my rx for a second or two, but after we stared at it for five minutes and started really looking at it we found that the elevator was higher on one side than the other.

So for the two questions, How can I get the epoxy apart without wrecking the plane or the elevator? and how can I make this square?

any help is appreciated

thanks
