Equipment Description

The TURNKEY Gryphon Dynamics GD-28X heavy lifter octocoper is professionally built by BFD systems, and was only test flown for under 5 minutes... basically in NEW/MINT condition. It comes with two complete sets of arms with motors and props to maximize flight time in specific weather conditions or mission specific use, or for piece of mind to have a complete backup.

The drone is capable of 18-23 minutes of flight time at the full 55-pound FAA weight restriction. Gryphon Dynamics manufactures its drones with an advanced carbon fiber weave and fabrication techniques that instill confidence for pilots that the payload equipment is secure and stable with minimal vibration. The GD-X line of drones is equipped with a larger center plate, thicker carbon fiber, ultra-stiff booms, and aluminum joints for effortless weight management and flight control.
