My sheeted foam wing halves are now joined at the center.
I know what we did in R/C pattern with fiberglass and resin to reinforce the center joint. Probably a bit overkill for CL.
I was thinking a couple of layers of .75 oz. glass cloth about an inch on each wing half?
Soooooooo, What are you guys doing to reinforce the center joint of a sheeted foam wing.
Thanks in advance.

I use a strip of 1 to 1.5 inch glass around the center joint, and cut 2, .5 ounce fiber glass ellipse about the size of a football, one top one bottom, attached with finish resin, long direction going toward tips, I also overlap the silk span in the middle, take care to NEVER sand the fillets too deep, as you will go thru, and into the sheeting, this will create a stress point and the wing will snap off at that point. I also put light thin fillet around the inside, this makes it very strong, helps to fuel proof it and Prevents fillet cracks
