Franz Stolz built his design in 1909 in the German town Rastatt. Due to its form it was named the ‘Torpedo-Flugmaschine’ [Torpedo Flying machine]. To fund (further) construction the design of Stolz was exhibited against payment in the Carl Franz Halle, but this financial help was not enough. Stolz had to auction his machine in December 1909 and the machine never did fly.
