Guided Missile concept

Approximately 50% chance to hit the target on the AI target lock assist only, and up to 100% with player manual targeting assistance.

Controls
Heli:
"activate first stage for gyro YAW controls.
Throttle carefully(slowly) to avoid kraken and/or explosions.
Use regular Pitch/Roll/Yaw or lock heading for flight assistance(recomended, gosh we need mause-joystick controls so much!)

Take off on 70-71%.
It can land on autorotation, but it highly depends on your skill.

Missiles:
Switch to ASM control chip and throttle from 20 to 100 percents before launch.
Stages 2,3 launches missiles, I highly recommend you to lock heading or target before launching.
Also it is better to launch them with slow motion so you can manipulate them quickly enough.

Warning: Do not throttle more then 88% before missiles launch (risk of swash plate explosion), also there is bug that will start slightly pushing helicopter to the ground after missiles launch. Throttle more to compensate that.

(Sadly, missile manufacturer do not give garanties that it will explode on target craft impact, but it have much more chances if it hit the ground or building)
