Build 10
When you insert the leading edge rods into the leading edge, be sure that the leading edge rod goes over all the bungee holes, and inside all the leading edge strips. Sometimes putting a wooden dowel sanded to a point at the end of the leading edge rod helps to get the leading edge thru the leading edge strips. Use your finger nail rubbing along both sides of the rod to be sure that the leading edge rod did in fact go thru the strips.
