Happymodel Sailfly-X: “Toothpick class” micro FPV drone

Happymodel Sailfly-X FPV drone

Following the great success of the Snapper7 and Mobula7, Happymodel recently released another micro-class FPV drone called Sailfly-X. Thanks to its ultralight 105 mm frame and powerful KV9000 brush-less motors it is suitable for both indoor and outdoor flights.

Like other “toothpick” FPV drones, the Happymodel Sailfly-X is also based on the versatile Crazybee F4 PRO flight controller. According to your flight skills, you can opt for Angle, Horizon or Acro flight modes. Featuring integrated BetaFlight OSD, you can monitor battery voltage and other telemetry flight data remotely via your FPV goggles/monitor.
