RE: Building the original Byron P-51 Mustang
After cutting them out, I did a temorary test fit by taping them onto the wing. They seemed like they fit great. I cut the stringers to size and glued them on all of the covers. The insrtuctions say to glue the stringers back away from the trailing edge aprox 1/4" but I felt that wasn't enough so I backed them off another 1/16" or so. Now it was time to glue the top aileron/flap covers on and let them set up. The directions say to glue the top cover on, install the aileron then to glue the bottom cover on. I wanted to be able to take the ailerons out for finishing and painting so I didn't. I got all of the covers glued on and the left wing aileron was perfect. Assembled easily and fit great. Hmmmm, the right wing - well crap, the covers were too close together and the stringers that were inside of the covers were not backed off enough! When the aileron was moved up or down, the stinger would catch it, stopping the aileron. I should have backed the stringer off even more. DRAT. After some trimming, beveling of the stringers, and a bit of sanding, It eventually went on well. Upon inspection, the plastic tab that holds the inside of the aileron with the plastic bearing was not put into the wing straight by the original owner. I was able to fix that and it is a tight fit now, but later I will be sanding for the finish work and will make all of the parts fit evenly with a bit of a gap between the surfaces to compensate for the thickness in the glassing.
