GD-M20 has the advantages of high flight speed, large load capacity, long flight time, good plateau performance, etc. the airborne performance is superior to the international advanced same class unmanned helicopter.
The Mk UAV has a modularized airframe and lowers gross weight. Meanwhile, the special design and materials extend the maintenance period by ten times than traditional UAV, which reduces maintaining and using costs.
It was lighter than a traditional helicopter，X-Control improved the unique tandem layout, make it lighter, and have a larger rotor disc surface than a traditional helicopter. So Mk can double the takeoff weight and has only quarter transportation volume than other UAS in the same gross weight.Longitudinal rotor overlap design maximizes the total disc surface, which increases payload ability. And the two sets of rotor blades rotate in the opposite direction, it eliminates the counter torque from each other, so every power produced by the engine can be used for lifting. In addition, symmetrical aerodynamic could improve the effectiveness of maneuver and flight speed.
