General instructions:
AG1 Cockpit open. Do not Activate it during flight.
AG2 Activate AGCAS Automatic ground collision avoidance system, especially useful above sea. Please do not push or roll the stick too rapidly when AG2 is on.
AG3 Drag Parachute. You need a little bit trimming if the landing weight is heavier or lighter. The correct attitude is 100m per 1.1 kilometer far away from airport. The correct landing speed is 280-330kmph.
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.
AG7 FOTD fiber optic trailing decoy System, Open guide head electronic false target, do not activate that on the ground, or you will destroy the plane. Do not AG8 or it would not work.
AG8 Open retractable Gatling bay for use
Trim for trim
VTOL for flap, DO NOT FORGET TO OPEN FLAPS FOR TAKING OFF

Tip: Roll at the direction of rolling when you enter a spin, then you would be easier to fly out of it.
7.62mm Gatling, 20mm M197, python-4, Hellfie, AIM7R

Block 3 upgraded points:
1. FOTD Fiber Optic Trailing Decoy added by AG7. It is especially useful when avoiding SAMs, the rockets would not hit you if you AG7, going sidewards to avoid the rockets.
Enabling to avoid rockets without countermeasure dispenser.
FOTD fiber optic trailing decoy System, Open guide head electronic false target, do not activate that on the ground, or you will destroy the plane. Do not AG8 or it would not work.
2. Much strengthened firepower, with a pair of retractable M197 20mm cannon on its back activated by AG8, which is very useful in dogfight.
3.Reworked landing gear, with better turning performance.
4.Totally enhanced flight control system, which upgraded flight control experience.
5. Upgraded HUD. With better view.

Upgraded stealth F4 primer plus Phantom III Block 2, Main upgrade 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.

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.
