Facetmobile FMX-4 - It was built by Barnaby Wainfan, Rick Dean, and Lynne Wainfan to explore the characteristics and potential of this type of airplane. The configuration was developed using a combination of analytical methods, radio-controlled model testing and wind-tunnel testing. In all, 8 radio-controlled models were built and flown. Construction of N117WD took 2 1/2 years. First flight was April 22, 1993. Total flight time to date is approximately 130 hours.
You call it a hoverbike, I call it a one-manned personal drone, because that’s what the Scorpion 3 or the S3 looks like. With four propellers in four corners, the S3 looks like a massive drone and even takes off like one. Labeled as an eVTOL (or an electric vertical take-off and landing), the S3 comes powered by a 12.3kWh battery that gives it 40 minutes of flight, which translates to around 13 miles on a full charge.
