This version of the 400-series employs a more modern aesthetic. Ideal cruising altitude for efficiency is 15000ft - 33000ft. Extremely stable to land and take-off (so long as the speed thresholds and configurations are adhered to).

AG 1 – Left engine 2
AG 2 – Left engine 1
AG 3 – Right engine 1
AG 4 – Right engine 2
AG 5 – Landing lights and speed breaks (break input only)
AG 6 – Navigation / anti-collision lights
AG 7 – Fuselage cabin lights
AG 8 – Reverse thrust (break input only)

For take-off, activate all 4 engines and reverse thrust (to taxi on runway), set primary flaps (VTOL) to half down, and rotate with trim between 210mph and 240mph.

For landing, activate speed breaks / landing lights and ensure reverse thrust is also activated, Set throttle between 50% and 60% depending on fuel levels, full flaps and full trim (she will stabilize very forgivingly). Very smooth to land when properly configured.

Revisions:
Primary wings completely rebuilt, engine positions adjusted, horizontal stabilizer adjusted.
