GO SLOW DON'T JUMP TO CONCLUSIONS.

Before you get all crazy and start changing things it would be a good idea to find out what the design incidences are! What do the plans say about down thrust and such.

When I check incidence I set the fuselage in a jig where the horizontal stabilizer is at zero degrees. Then I get a reading on the wing incidence. I fabricated a set of jigs that allows me to set up everything very stable to get measurements, anything less is just guessing.

You said the airplane came through the crash quite well it is doubtful the wing saddle or the horizontal stab incidence has changed to any degree unless the fuselage was broken.
