F-4 Primer plus phantom 3 Stealth version block 4, Block 4 new features:
1.Enhanced Fiber Optic Trailing Decoy system activated by AG4 with severe electronic countermeasures, which is more than 90 percent effective for any kind of unprogrammable air-to-air missile and every kind of SAM within only some slight turns.
However it could not be used while taking off or landing because the severe electronic countermeasure would greatly effect many electronic devices on the aircraft itself. To install this system on the plane and keep the plane working normally when releasing electronic countermeasures, the flight control system of this aircraft has been totally updated.
2. Unjammable aerodynamic-controlled guided rocket. The upgraded AIM-7R is an unjammable air-to-air rocket. Each countermeasure is useless when faced with upgraded AIM-7R.
Even when the enemy continuously releasing the countermeasures, you could still launch upgraded Aim-7R at the gap of the countermeasure release.
However, you should continuously switch on the selected rocket before it hit the target. For example, after you launch AIM-7RSparrow1, you should keep selecting AIM-7RSparrow1 before the rocket hit the target. You could only guide the rocket to one target at the same time.
3.Brand New CLOS mode operated in cockpit Activated by AG3.It enables the minigun and AIM7R guided rocket to aim and fire at the direction of pilot sight directly using helmet-steered aiming system.
AIM7R CLOS mode is especially useful for attacking untagged ground target from very far away from the plane.
The target altitude is measured in meter.
Pilot should adjust the target altitude manually by adjusting VTOL tab before launching the AIM7R guided rocket, then turn the camera towards the target and force launch a selected rocket, keep the camera turning at the target for 1 second at normal speed, then the AIM7R guided rocket in CLOS mode would fly towards the selected target automatically.
4.Totally upgraded flight control system, greatly improved stability while at high angle-of-attack and high speed, and high symmetrical acceleration. Post-stall control performance increased.
5. Totally upgraded autothrottle performance, which greatly save fuel while AG6 and much more easier to control the plane landing on airports by AG7.
6.Helmet aiming system added.

General Instructions:
AG1 Cockpit open or short runway takeoff high AoA maneuver mode.
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: CLOS MODE, all the Weapon Command to line of sight of the cockpit, including guided rocket and minigun.
You should use CLOS mode in cockpit sight mode.
VTOL is for setting target altitude for AIM-7R CLOS mode, so it would not work for flap while AG3, do not AG3 while takeoff or landing.
AIM-7R CLOS mode instruction:
Using VTOL to adjust the altitude of target first before launch, then activate group 5 and launch the selected rocket, use the helmet-steered sight to look at the target at the same time and keep for about 1 second in normal speed. The Launched AIM-7R rocket will directly move towards any untagged target you selected seconds ago. It is especially useful for any ground target in any place, and even useful for untagged target.

AG4: Enhanced FOTD fiber optic Trailing Decoy with electronic countermeasures, it could not be used while taking off, landing or aiming at the target, because it would affect many of the devices on the plane itself.

AG5: Open rocket bay to activate air-to-air rockets. The upgraded AIM-7R is an unjammable air-to-air rocket. Each countermeasure is useless when faced with upgraded AIM-7R. Even when the enemy continuously releasing the countermeasures, you could still launch upgraded Aim-7R at the gap of the countermeasure release.
However, you should continuously switch on the selected rocket before it hit the target. For example, after you launch AIM-7RSparrow1, you should keep selecting AIM-7RSparrow1 before the rocket hit the target. You could only guide the rocket to one target at the same time.

AG6: Autopilot helps to aim at the target. With autothrottle when throttle from 30 percent to 70 percent.
When AG1 OR AG3 AT AG6 MODE, THE PLANE WOULD FLY LEVEL AND STRAIGHT by autopilot, the autopilot could automatically aim at the target only when AG1 AND AG3 are off.
AG7: Anti-sidewind half-automatic landing mode, you need to target at the runway by yourself and do some trimming. The correct landing speed is 400-450kmph. The correct altitude is 100m per 1.1km from the airport. Do not activate AG1 or AG2 or AG4 or AG5 or AG6 when AG7 is on. You must land in this mode, or It is too dangerous. Automatically release drag parachute while touch-down.
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

Takeoff
Flaps: 50%
Pitch up: 350km/h

Landing
Flaps: 100%
Trottle: 5%
Speed: 280-330km/h
Touchedown speed: 280-330km/h
Remember to AG7 before landing for drag parachute

Block 3 Major upgrades:
1. Much strengthened firepower, with a pair of retractable M197 20mm cannon on its back activated by AG8, which is very useful in dogfight.
2.Reworked landing gear, with better turning performance.
3.Totally enhanced flight control system, which upgraded flight control experience.
4. 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.
