[1][2] In 1951, members of the Club de Planeadores Otto Ballod and Reimar Horten built a new version, called the H.Ib, using a more modern section and the control accomplished by elevons located on the outer wings, omitting the inner elevators/flaps.
[2][3] The H.I was first flown in July 1933 at Bonn-Hangelar airport, initially using bungee cord, then auto-tow, leading to winch launches to 300 m (1,000 ft).
With the flying qualities of the aircraft satisfactory, Walter Horten set off under aero-tow to the 1934 Rhön meeting at the Wasserkuppe, towed by a Klemm L.25.
A telephone request to Alexander Lippisch for a tug to fly the H.I back to Bonn was unsuccessful, so Walter flew the H.I for one more time, landed successfully, broke up the aircraft and burned the remains.
