    Simms' Armoured Quadricycle, built in 1899, is considered by many to be the first armored fighting vehicle (AFV). It was the first motor vehicle designed as a weapons carrier, and had a tiny front armor shield. Frederick Simms' invention carried a 7.62 mm Maxim machine gun, and was both pedal and motor powered.

    The 1/6 scale R/C Armored Quadricycle carries a servo fired 0.40 caliber Splatmatic XJ40 paint ball marker and has top speed of approximately 3 mph. The chassis and Fred Simms' stunt double came from a Radio Shack R/C Road Rustler bought on sale for $18. Fred Simms' head and hat were modified from a Wal-Mart fireman action figure. The seven inch diameter spoked wheels came from Herbach and Rademan.

    Because the XJ40 has very light trigger pull force, a plastic servo horn was cut to form a simple cam to fire the gun as shown in the lower left corner of this image. The XJ40 uses small 12g CO2 cylinders (not shown) that provide about 100 shots each. One-half inch PVC pipe and copper fittings were used for the 15 shot gravity feed magazine. An existing screw hole near the bottom of the XJ40 grip was used for mounting to the chassis.

    The chassis uses a standard R/C car 9.6 VDC battery and has two channel R/C control. Fred Simms sits on an auxiliary 6 VDC battery pack and R/C receiver to control the trigger servo. The antenna for the auxiliary R/C unit is loosly attached to the original antenna for the chassis. Fred is protected by 0.093 inch thick acrylic frontal armor.

    A standard servo was attached to the XJ40 handle using 4-40 screws and a small acrylic cross-brace. The XJ40 handle is composite plastic and machines easily. Two holes for the aft end of the servo were tapped into the handle behind the trigger. One hole for the top of the cross-brace was also tapped into the handle just in front of the safety. The bottom of the cross-brace was secured to the trigger guard with a nylon wire tie as shown in the left side view above. Two holes for the front of the servo were then tapped into the acrylic cross-brace.
