Block 2 new features:
1.Enhanced Fiber Optic Trailing Decoy system with severe electronic countermeasures activated by Ag7, 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.
2. Strengthened ground attack payload to more than 900kgs payload, 14 air-to-ground rockets have been increased.

General instructions:
AG1: THROW AWAY EXTERNAL FUEL TANKS

AG2: AGCAS Automatic ground collision avoidance system. Do not AG2 while landing.

AG3: Throw away all armament.

AG4: Fold the wings of the aircraft carrier based aircraft.

AG5: Activate air-to-air rockets or bombs

AG6: Autopilot helps to aim at the target plus autothrottle at best speed, but consume too much fuel.

AG7: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.

AG8: Activate 60-degree retractable 20mm gun system. more than 840 rounds per minute each side.
Tips:
If you use P51 itself only without helping F104 to takeoff, you must AG7 before takeoff or landing.

Main armament: Hellfire, SDB-125 JDAM
Tips to use air-to-ground armament for aerial targets: Using air-to-air mode to lock first, then select air-to-ground mode and launch air-to-ground armament.
EOTAS 360-DEGREE LOCK ABILITY

Takeoff
Flaps: 50%
Pitch up: 240km/h

Landing
Flaps: 100%
Trottle: 15-20%
Speed: 220-260km/h
Touchedown speed: 220-260km/h

Maximum speed 650kmph for level flight at 4000m without payload, and 580kmph for level flight at 4000m with maximum payload plus external fuel tanks.

Land-based modern turbo P-51 multipurpose attacker aircraft, which is much cheaper than Traditional attack helicopters, with only 1 1900-HP GE T700 engine, but have almost the same payload and armament with AH64, and fly faster, higher and further than AH64. It is designed to replace both AH64 and MQ9. Its price would be almost the same as MQ9, but have better payload and survivalability, more reliable than UAV. For the maneuverability, it could also fly very low with the help of digital flight control system AGCAS. It is equipped with 4 air-to-surface hellfire rockets, plus 4 smallest 125-kg JDAM SDB-125.

It could be useful for front-line airport because its runway requirement is short and its maintenance is much easier than AH64, but use the same engine with AH64 and UH60.

Please throw the SDB-125 bomb at a high altitude and closer distance, about less than 2 times of altitude, to ensure the ignition of main bomb.

The P51 attacker is friendly for green hand pilots, so that the best pilots only meed to fight in the air.
