Rebuilt the VTOL system from the ground up, making it completely unlike and far superior to its predecessor.
Equipped with a new engine for faster throttle responses
Added automatic altitude holding, tuned to perfection with swift and precise control of the VTOL engine
Now automatically deactivates and remains on standby upon transitioning to forward flight (GS > 300 knots)
Perfected stability to the point of being capable of absolute zero movement if that is desired
Suitable for operations requiring slow but controlled flight, such as air refueling with the slow tanker. Assisting the pilot with its altitude hold and directional control, the main engine can be used to maintain a slow speed matching that of the tanker, and the directional control can be used to precisely position the refuel probe on the nose of the jet with the drogue on the tanker, even with zero assist.
