ha ha......here's a funny one...ha ha.......Mine were off a litle bit ( not a half an inch) and i didn't even notice. Oops! Kind of embarassing. I bring it up just to mention it flew great anyway! I had just a touch of mixing to do, elevator to rudder and now it tracks perfectly through anything. I probably should fix it, but you cant tell by looking and the long, slooowww rolls are awesome, as is everything else. It tracks very much like some of the pattern ships I've had.
