It holds fine if you glue the whole way, not excessive but enough to hold, It makes it easier to work you way from one tip down to the other, or glue one side, then when its dried glue the other side down and hit it with the kicker while holding it there. In all honesty I think it appeares worse a bend than it really is, I had my doubts but not after months of flying did it even budge. if you are realy concerened with it, after you glue it than tapoe it with hinge tape(a strip the length of the wing folded over the rod and onto the wing). But I dont see any problems with it...And I dont currently belong to any clubs, most clubs around here are all glow and regular electrics, I dont think theyd aprreciate my close in hovering and harriers, My dad has a car garage on rt 72. Where the lebanon lancaster line crosses it, theres a PA turnpike exchange right there to, anyway, theres a big field right out front of his place I fly there, also in my front yard, or actually in the street, but its a culdesac so its not busy at all.
