Like the wing, the tailplane was strut braced from below. The rear surfaces were braced against lateral deflections by pairs of wires from the upper wing surfaces to the top of the fin and by similar wires from below to its bottom.

The wing was mounted on a fuselage pedestal above and immediately behind the cockpit in the flat sided forward fuselage. Though open, this cockpit enclosed the pilot as in a light aircraft, rather than leaving him fully exposed as on many earlier primary gliders. A pair of
