If you lined up the plywood joiner you should be OK...As for the struts the CA is to tack the wires, then epoxy the sandwich together...There is a trick to getting the wings, struts together at one time...I first install the top wing, install struts in top wing(don't slide forward yet), then set bottom wing in saddle, line up struts, now slide forward and lock into place, the tighten bottom wing...Oh and try not to puncher the covering with the wires!!! When ya get there...Making great progress...Took me 6 months to build mine...
