A roadable vehicle with a single nacelle assembly that contains a pair of inline counter-rotating propellers. Two inline counter-rotating engines are directly connected to the propellers. One engine is shut down in horizontal flight to improve efficiency. Gimbal mounting the nacelle assembly permits thrust to be directed forward to back and left to right to control the vehicle position in the horizontal plane, when hovering. Varying the relative engine speeds controls yaw. The roadable vehicle is adaptable as an unmanned vehicle. The foldable wings equipped with automotive type wheels provide for travel off-road as well as on the highway. |
