The magazine holds five missiles. Missiles are launched by cocking a firing pin by rotating a small knob protruding from the far side of the fuselage. The firing pin locks in position. A spring-loaded slide mechanism loads one missile at a time into the firing chamber. A push-button, mechanical release fires the missile.
Range is about five feet.
The firing pin is powered by a LEGO bungee cord from on of the bungee racer sets. The minifig above is shown loading a missile into the magazine. Pneumatically actuated loading ramp. Pneumatically actuated landing gear that fully recess into the hull. Panels can be manually closed to cover the landing gear after they have been raised.
