 There were access doors on either end of the KT7 and the rear and the front look nearly identical save for the headlamps.An early original brochure announcing the KT7 actually shows its designation as a KT3a and calls it an "improved KT3" but the production brochure has it designated as the KT7.The KT7 was tested by the FAA for use in Alaska but failed to achieve a 20 mph speed requirement; the sales brochure claims a 15 to 25 mph speed "depending on transmission/engine options."
