New feature: 1.Greatly improved aerodynamic performance and decreased drag. Flutter decreased. Upgraded engines with British O593 engine.
2.Upgraded avoinics system, radar and aiming data is now shown on the HUD. Flight data are shown on the screen.
3.A Hellfire is added in the bay. Air-2 problems fixed, the new air-2 plus is a conventional head heavy guided rocket, with a heavy head estimated at 250kg. Using late Aim7R infared and semi-radar homing rocket, with a range of 15km. Using Python4 rocket with much better turning performance which could launch at 60 degrees.
A greatly improved stealth supersonic flying wing NGAD aerodynamic concept from F106 old structure.
Nicknamed 'Angel' features:Reshaped tails both suit supersonic aerodynamic stability, supersonic trimming and turning performance, plus stealth requirements.This solve the problem of last version, which is calculated to have a bad supersonic stability.
F-106 stealth-modified and Maneuverability strengthened version with upgraded digital flight control and more realistic aerodynamics, intended for a cheap version of stealth aircraft, and it's a fairly old design. It's featured on supersonic performance compared with F35.
F106 primer plus Stealth strengthed version concept, developed from earlier F-106 stealth project. Canard and vertical stablizers are all cancelled.Stealth performance greatly improved. Thrust Vectoring is increased to 35 degrees.It uses large strake wings like F18 early versions.
Tips: 1.Activate group 3 to open drag parachutes, activate group 4 to throw the tanks, and activate group 5 to open the missile bay, deactivate group 8 to retract the 20mm Gatling.
2.If you want to improve the best turning performance maneuverability at low speed, please turn down the VTOL control block.
3. Hellfire's head is somehow light and it cannot threat large ground targets, it could deal with
clumsy planes or cars on the ground, its correct usage is using python4 rocket to lock the plane or car first, and then activate group 7 to launch the Hellfire. It's tested to destroy the Jackhammer truck.

Maximum IAS recommended to be less than 1300kmph IAS. If IAS is more than 1400kmph, the flutter would destroy the plane.
It could easily reach M2 above 8000m altitude.
Maximum tested speed M2.42 at an altitude of 20000m.
When you fight, the plane would accelerate very easily, when you turn, the plane could even
still accelerate. Please notice the IAS to avoid the plane to breakdown at a high speed.
Turning performance: Pitch rate 40 degrees per second at 500kmph at sea level, roll rate 300 degrees per second at 500kmph at sea level.If maneuver Gravity is more than 15gs, the aircraft might breakdown.
