I do rebuilds on "rekitted" planes for the guys and several were Ultimates, the part that always bugged me was trying to get that $#(#)* pin back into the top wing into the cabane, this time I just turned the top bar over, put two pieces of metal tabs up into the top wing with holes in them and put the pin in, the two tabs extend down with holes drilled to match the upside down bar, sure makes it eiaser to assemble Mike
