|
| 4. | It was a roll control, tandem open cockpits and Fokker's distinctive comma-shaped rudder.
|
| 5. | Roll control was by differential actuation of the wing-fan exit louvers.
|
| 6. | The roll control / parachute system was tested at Mach 2.2.
|
| 7. | Roll control was via a system that pivoted the entire lower wing surfaces.
|
| 8. | Roll control is primarily achieved by use of the wing elevons.
|
| 9. | Flaperons and vortex generators are used for roll control and low speed flight.
