Three two place sailplanes were laid out in 1948, and completed the following year. With these aircraft, I hoped to fill six basic requirements with minimum expense, while standardizing the equipment:
- Provide a two-place training glider, that could fly for extended periods in thermals, in order to keep training costs down.
- Provide good visibility for the instructor while the student was practicing "blind flying" on instruments.
- Provide a suitable glider for the student's first solo flight.
- Provide an adequately stressed airframe for acrobatic maneuvers.
- Provide a structure that could easily be converted to a motorglider.
- Provide a high performance competition sailplane.
- The "in house" designation for the I. Ae. 34 became the Ho XV a. The official description was as follows:
The single spar all wood structure consists of three parts, with a 60 cm wide center section. The entire wing is plywood covered, with elevons and flaps along the trailing edge. The elevons are
balanced with lead weights. Ball bearings support all pushrods. Drag-rudders retract flush into the wing tips, and terminal velocity airbrakes are installed near the wing roots. The wing can be
removed by four people in a few minutes. The all wood center section has two tandem wheels near the center of gravity, with a skid in front, to enable it to make off field landings without danger
of flipping over. The rear seat is located 30 cm above the front, giving both pilots identical view. A single instrument panel is visible from both cockpits. Provisions for oxygen and seat parachutes are included. The rear control stick
may be removed for passenger flying.
