You will notice that Phoenix Giles has a pretty small structural cross-section area just forward of the wing. It is also a sharp corner, which makes what they call a "Stress riser". It would be good to carefully epoxy some fiberglas cloth in that area, both sides, to add some strengh for those bumpy landings.

Your LA wil haul that plane around just fine, since you're not expecting lots of vertical or wild aerobatics.

Best wishes,
