Another view.



The rear leg is wrapped with Kevlar and glued with CA.  The front leg is attached by flooding it with thick CA and pressing in wood filler on top to encase it.



The  original plan showed all these strings converging at a point on the centerline.  That would be ugly.   I changed it to a more usual arrangement.  A 1/64 ply doubler
was laminated on the top of the 1/32 balsa center section sheeting.  This was to allow for a center bolt wing hold down.  Small strips of balsa were glued on in the
  curve where the fuselage profile intersects the wing, shown on the plan.  The balsa was sanded nearly all off, it is just an anchor for the covering.  The stringers
 were sanded as necessary on the lower front edge to match the wing and installed.  The outside corners were filled with sheet balsa and sanded to fair in.



The elevator and rudder are hinged with small Robart hinges, with the pivot points on the center of a round radius sanded
in the surface leading edges, so the gap is minimal and stays the same as the surfaces move.
