Upgraded stealth F4 primer plus Phantom III Block 2, Main ulgrade points:
1. Fully upgraded digital flight control system, with much better low-speed performance, which could keep 40 degrees angle of attack at very low speed of 200kmph, with full control of rolling. The pair of canard and strake wings shaped like f18 fully solve the high-angle-of-attack problems of original F4. AGCAS and autopilot which helps air combet also upgraded.
2. Rocket bay strengthened with more details.
3. Canard connection system upgraded.
4. Automatic combat throttle is added in the new version of the plane, which could help the plane to fight at the best speed of turning. You should activate AG6 first and throttle to 50 percent for the automatic combat throttle, you could both control the thottle manually and automatically when AG6 is activated.

Tip: AGCAS Code bug fix: Change the variable name from 'Pi2' to 'Pi'.

General instructions:
AG1 Cockpit open and fold the wings. Do not Activate it during flight.
AG2 Activate AGCAS Automatic ground collision avoidance system, especially useful above sea.
AG3 Drag Parachute
AG4 Launch all air-to-air rockets for ground target after AG5 activated and Target locked by hellfire
AG5 Open rocket bay
AG6 Autopilot helps to targeting at the selected target automatically. Do not use it with the system autopilot at rhe same time. You can still control your plane when the AG6 autopilot is on. This autopilot is only a helper for airial combat, it could help a lot for manually control. Automatic combat throttle is added in the new version of the plane, which could help the plane to fight at the best speed of turning. You should activate AG6 first and throttle to 50 percent for the automatic combat throttle, you could both control the thottle manually and automatically when AG6 is activated.
AG7 Launch hellfire for aerial target after AG5 activated and Target locked by other air-to-air rocket
AG8 Open retractable Gatling bay for use
Trim for trim
VTOL for flap and high-AoA manuevers.
Tip: Roll at the direction of rolling when you enter a spin, then you would be easier to fly out of it.
It's advised to release a some flap during airial combat to relax gforce limit.
7.62mm Gatling, python-4, Hellfie, AIM7R

Stealth, maneuverability and electronics all strengthened F4 primer plus version.
It's reengined with British Olympus O593 engine, and have a much superior performance than two original J79 engines.
So it has become a single-engined plane.
Roll Rate more than 270 degrees per second at 500kmph IAS.
Maximum IAS recommended to be less than 1400kmph.
Supersonic cruise at M1.8 without afterburner at 12000m 80 percent throttle.
Reach M2.25 at 20000m altitude.
Pitch rate 30 degrees per second at 600kmph IAS at sea level.
Longer range than F106 with inner fuel, but less thrust to weight ratio.
Equipped with EOTAS, which could lock on any target from every direction.
The correct landing speed is 280-330kmph.
