Ok, I got these cap strips in today. It helped a little with torsional rigidity, but not as much as some cross bracing would. Also got the aileron servo trays epoxied up today too. No picture of that, they're not very exciting. Next installation should be of the mod that corrects my earlier error with the upside down wing rib. Didn't want to do that tonight, and I had too much calculus to do today. Hopefully soon!
