I got two of the Great Planes Folding Airplane Stands and tied them together with 3/4" x 1/16" thick aluminum angle. I chose not to use the folding feature of the stand and just screwed into the center braces from the end pieces. The parts that cradle the fuselage are foam padded and each are adjustable left and right to enable different fuselage widths as well as a range of center to center distances of the fuselages. I also cut down the height of one set of end to allow clearance for the wing on the OV-10.
