21. Pairs of interplane struts leaned outwards and diverged toward the more widely separated upper wing spars. 22. This differed principally in having a pair of triangular rudders mounted on the aft outboard interplane struts . 23. The Special was a chord, unequal-span wings connected by pairs of parallel interplane struts . 24. Steel tube was also used for the interplane struts , these being of a special streamlined section. 25. These had an even larger vertical tail, interplane struts of narrower chord, and no wheel spats. 26. The lower wing was close to the ground so two underwing skids were added below the interplane struts . 27. There were outboard outwardly-splayed interplane struts with the braced stabilising single-stepped floats mounted below. 28. The Perch was a two bay biplane, though the inner interplane struts were close to the fuselage. 29. The upper pair formed a stagger, with the interplane struts at about 30?to the wing normal. 30. A pair of stabilizing floats were mounted outboard, braced to the wings spars under the outer interplane struts .
