The present invention is a winged VTOL aircraft of novel configuration that utilizes a single-axis rotor mounted at an oblique angle within a forward-facing, bifurcating duct, that is controlled by a plurality of servo driven vanes, producing a mechanically simple, redundantly controlled vehicle that can carry cargo, people, or otherwise, directly from point to point. The configuration uses sets of vanes to produce both moments and forces referenced around the vehicle's center of gravity, thereby, allowing the vehicle to translate in a level position, or stay stationary relative to the ground while at a slight pitch or roll attitude. This feature is very important for autonomous vehicles to accurately pick up and drop off payloads on unlevel terrain or in windy conditions. Other rotor vehicles require pitch or roll attitude to translate or compensate for wind. Complementing this vehicle's mechanically simple rotor system is a novel mechanism that collectively drives the pitch of the rotor blades by combining the input from three separate servos. Each servo can be controlled by redundant fight control systems.
