I have built one and I think it's a piece of JUNK. The hardware is crap the wing hold down is at the wrong angle for the bolts coming through the wing had to break and refix the glue joints, what glue? very little. The hinges are pinned but not glued in the slots for the hinge is 1/8 by1/2 too big and sloppy the pins have no points so most do not go through the hinge. The balsa is the cheap white kind very soft, Tee nuts for the bolts are plastic and the bolts are too small in dia. Looks good finished but I would not by another kit. The GP UCD is ten times better for $30 more
