Editing Heinkel He 100 (section)

=== He 100 V3 ===
The V3 prototype received the clipped racing wings, which reduced span and area from {{convert|30|ft|10|in|order=flip|abbr=on}} and {{convert|14.4|m²}}, to {{convert|24|ft|11|in|order=flip|abbr=on}} and {{convert|11|m²|abbr=on}}. The [[Aircraft canopy|canopy]] was replaced with a much smaller and more rounded version, and all of the bumps and joints were puttied over and sanded down. The aircraft was equipped with the 601M and flown at the factory.

In August, the DB 601R engine arrived from Daimler-Benz and was installed. This version increased the maximum rpm from 2,200 to 3,000, and added methyl alcohol to the fuel mixture to improve cooling in the supercharger and thus increase boost. As a result, the output was boosted to {{convert|1324|kW|PS hp|abbr=on|order=flip}}, although it required constant maintenance and the fuel had to be drained completely after every flight. The aircraft was then moved to Warnemünde for the record attempt in September.

On one of the pre-record test flights by the Heinkel chief pilot, Gerhard Nitschke, the main gear failed to extend and ended up stuck half open. Since the aircraft could not be safely landed it was decided to have Nitschke bail out and let the aircraft crash in a safe spot on the airfield. Gerhard was injured when he hit the tail on the way out, and made no further record attempts.
