Be it humanitarian, military, or industrial, all sectors have the same UAV needs: VTOL Flight Endurance Significant Payload Hover Unmanned Aerospace has addressed these by designing and developing the GH-4. The GH-4 is based on the GYROCOPTER principal. With the ability to convert to a helicopter-like aircraft for VTOL (Vertical Take Off and Landing) and hover; without any of the complexities, added weight, power consumption or maintenance associated with a helicopter. The GH-4 is a unique aircraft, in a class of its own with over two hours of flight time, including VTOL and hover on one charge. We achieved this milestone with our patent pending rotor head technology, combined with power management and aerodynamics.
