I would say the 1/8" hinge point is plenty strong for your CAP, as long as you use enough of them. I rehinged the elevators of my 28% Laser with 1/8" hinge points after I broke a CA hinge. The surfaces are built up with 3/8" stick like your CAP. I installed six 1/8" hinges on each side. There's no way I'll have hinge failure now! If I had to do it again I would probably only use 4 or 5 hinges per side. Good luck!
