Weiss, H.M. Strap-on

In the mid 1930's HM Weiss built and used a strap on flying machine for survey work in China before the outbreak of WW2. He used a main rotor for lift along with a torque stabilizing rotor. The main rotor was perpendicular to his back and he positioned himself for lift like a runner leaving a starting gait and balanced the weight like a "fireman's carry". The machine was made of aluminum and cast iron and weighed 72 1/2 pounds when fueled.

Peter Weiss, nephew of the builder, was in possession of this machine, the original plans, photographs and films of it's operation and all the engineering specs. The family were seeking patent infringement awards, Peter Weiss stating “It bothers [the] family that my uncle, HM Weiss, received no acknowledgement from our government for his patriotic sacrifices and his remarkable engineering skills”.
