History
To achieve speed advantages over the conventional racing aircraft of the 1920s, has been omitted in the construction of P.7 swimmers. For the start of the aircraft should accelerate by means of propeller and be lifted with " Skikufen " out of the water. Thereafter, the main drive should be diverted by reconnecting from the propeller to the propeller to generate the further propulsion aerodynamic. It was built just a prototype, but never flew. Massive problems at the reconnect the drive train of 723 kW (1000 hp) payable V6 engine led to the termination of the experiments.
