Shear webbing on the spars.
Pica cut the webbing blanks to roughly the gaps between the ribs. The orientation though of the grain runs the same direction as the shear forces (horizontal). I would thing the grain should run perpendicular to the spar. Am I missing something...does it really matter?
Update for last night, Kansas tornado warning and hail limited build time. Had to rescue car and so forth. Got the ribs installed on the right bottom wing to the wing tip. Pretty straight forward to this point. I thought a bit more on that big empty space where the wing servo usedan to go. Candy bomb drop bay? That ought to make the scale guys go batty.... kidding Bill.
Will a covering like Koverall adhere to fiberglass. I was considering using a thin layer of glass on the sheeting joints and where the wing screws will go in. Generally I put a small piece of ply there to keep the balsa from being crushed. I though some glass might fair into the profile better.
