The Rhonbussard, designed by Hans Jacobs as a high performance type capable of cross-country flights of 200 or 300km (124 to 186 miles), first flew in 1933, coming in performance between the Grunau Baby and the high performance ships of the time.
Of conventional wood and fabric construction the Rhonbussard has cantilever two-piece high-set wings with a single spar and a leading edge torsion box and, as on the Rhonadler, the wings are secured to the fuselage by two conical bolts, so enabling rigging to be done quickly and easily. It lacks any spoilers, airbrakes or flaps for approach control. The long-span ailerons are operated by push-rods.
The pilot sits in an open cockpit under the wing leading edge, with a widescreen for protection, and the short oval section fuselage has a main skid for landing plus a tailskid, take-offs being made on a jettisonable double wheel. The tailplane is mounted on top of the fuselage forward of the rudder. One feature, which led to some notoriety, was the requirement for the wings to be joined together at the roots before being presented to the fuselage for attachment.
