  • POINT2

    Programmed automatic flight.

    Programmed automatic flight is available by GNAS SKY CORE flight control program. Flight just as you imagined is achieved by diverse settings.
    Programmed automatic flight
  • POINT3

    Outstanding stability

    Adopted controllable-pitch mechanism for propeller control. Achieved overwhelming robustness against strong and gusting wind compared with conventional drones, causing no unstable state even during descending.
    Resistant to wind
  • POINT4

    Sufficient payload capacity

    Realized more than 30 minutes of flight even with a payload of 3 kg. Long flight is possible even loading with heavy equipment.
    Secured obstacle detection capability
  • POINT5

    Secured obstacle detection capability.

    Unexpected obstacle is automatically detected by an obstacle sensor mounted on the front part. Achieve stable flight while reducing collision damage during automatic flight.
    Secured obstacle detection capability
