Efflux Mk. 1 Maiden Flight

The Efflux Mk. 1 is an EDF research testbed with various sensors including: GPS, airspeed, accelerometers, barometers, gyros, and a thrust measuring load cell. The fan will later be fitted with a variable outlet area nozzle and characterized over a wide range of throttle settings, outlet areas, and airspeeds with the ultimate goal of building a variable nozzle profile for maximum thrust, optimal efficiency, or a mix of both. Thank you to Flitetest Forums' CampRobber for providing the flight controller, GPS, and airspeed sensor: https://forum.flitetest.com/index.php?members/camprobber.45739/ A collaboration with WArbird Fan and HB Stratos: /channel/UC-QUXqCNIdTRXH4eYYZDF5Q /channel/UCtVT4b4VHOQANYqBKfRsTgw Electronics Specs: Freewing 70mm 2850kv 12 blade EDF 3000mah 4s 75C (Turnigy Graphene) Emax Simon Series 80A ESC Matek F765Wing running INAV BN-880 GPS + Compass ASPD-4525 Digital Airspeed Sensor Generic 5kg load cell and HX-711 interface board Physical Specs: 1.30 kg AUW 1.15:1 Static TWR Wing Area: 320 in² WCL = 13.9 More test flights to come. 0:00 Takeoff and Trimming 0:30 Flying 0:41 Out of focus! 1:07 Stall Testing 1:32 Performance Testing 2:00 Flying 2:19 Approaches 3:02 Final Approach and Landing 3:25 Takeoff (Alternate Angle) 3:38 Approaches and Landing (Alternate Angle)
