1 to lower arresting hook, 3 for nav lights, 4 to extend fuel probe VTOL to hinge wing. The true last gunfighter, the crusader is armed with quad 20mm cannons and four AIM-9B sidewinders (custom yay) for air to air. Air to ground armament consists of two AGM-12B bullpup missiles (also custom!) Instead of having flaps, the entire wing hinges, making this aircraft extremely easy to land. The maximum speed is just above Mach 1, so it can’t usually catch up with the faster planes, however it’s quite maneuverable for an American plane, so you may be able to outturn them. I’ve grown to love flying this plane. (Don’t use the boom 25s they’re the warheads for the bullpups)
