[Strike]

You need to set your bombsight altitude increase\decrease and adjust left\right controls in the options\controls section

I use alt+ WASD for the obvious W = UP D= DOWN A= LEFT and D= RIGHT.

This way, you simply fire the missile, and as soon as it's fired you can use your bombsight controls to adjust the direction of the missile.

You can either press and hold a key for a "quick" turn or for more accurate manouvering, tap the direction key.

NOTE: The missile only climbs\descends and yaws. It does NOT roll.

I hope you found this helpful
