Hybrid Drone


About i-Gryphon

Gryphon is a mythical creature with the wings and upper body of an eagle and the lower body of a lion and was able to fly grabbing several cows and horses together.

“i-Gryphon” was named after its features of the lifting-up of heavy goods into the air, watchful eyes while hovering, high information gathering capability and intelligent control.

Advantages of i-Gryphon

Heavy Payload Heavy payload
Longer endurance Longer endurance
Longer operational range Longer operational range
Autonomous control Autonomous control
Safety Safety
With engine driven high thrust force and stable attitude control by electric fans, i-Gryphon is characterized by heavier payload and longer endurance than that of conventional battery powered multi-copters, as well as by greater safety than unmanned helicopters.

Use Cases

Carrying Heavy Goods
Carrying Heavy Goods
Petrol powered hybrid drone i-Gryphon can both carry heavy goods and fly longer. Equipped with propeller guards, the drone is able to make a vertical ascent and descent. It can also take off and land on places surrounded by trees and buildings. The strong attitude control by electric motor driven propellers enables it to fly stably even in bad weather conditions.
Delivering High Quality Images
Delivering High Quality Images
i-Gryphon is equipped with visible and infrared cameras with high precision capabilities including HD image quality and 10-times optical zoom. The gimbal mechanism of the drone enables it to take pictures and video shots from any direction. As its payload weight is great enough, high accuracy cameras, LIDAR and sophisticated sensors can also be installed.
Transmitting Data
Transmitting Data
Various image data can be transmitted in real time remotely through 4G LTE network. A user can operate installed communication devices by using electric power generated by the drone (* this is optional). This feature can be used for various purposes such as relaying radio waves in the sky.
i-Gryphon can be used for a wide range of tasks, based on capabilities of longer endurance, heavy payload as well as devices (*1) that a user can operate using electric power generated by the drone (*2).
Note: *1 A user needs to install their own devices. *2 Regulator and rectifier circuits are required.
