Development and Design Philosophy
The Murphy SR-2500 Super Rebel emerged from Murphy Aircraft's desire to create a larger, more capable version of their successful two-seat Rebel design. Announced in April 1995, the project drew heavily on the expertise of Dick Hiscocks, former vice president at de Havilland and co-designer of several de Havilland aircraft. Hiscocks brought decades of aviation engineering experience to the Super Rebel's development, emphasizing rugged construction and exceptional short-field performance.
The design team configured the Super Rebel as an all-metal high-wing braced monoplane with conventional manual flight controls. Horn-balanced tail surfaces provided responsive handling, while three-stage flaps enabled impressive short takeoff and landing capabilities essential for backcountry operations. Electric trim assisted pilots during extended flights, and the robust landing gear could be configured as either tricycle or tailwheel depending on the operator's preferences.
Production History and Market Reception
Murphy Aircraft began shipping Super Rebel kits in late 1995, just months after the prototype's successful first flight in November. The company offered two build options: standard kits requiring 1,400 to 1,800 hours of construction time, and fast-build kits that reduced assembly time to 800-1,000 hours. By mid-2002, Murphy had sold 217 kits, though only 19 had been completed and were flying.
The aircraft found its niche in the backcountry aviation community, particularly among Canadian pilots operating in remote wilderness areas. One notable example was fitted with Aerocet composite amphibian floats, demonstrating the type's versatility for water operations. Production continued through the 2000s, with approximately 350 Super Rebel kits ultimately shipped before manufacturing ceased in 2008.
Murphy Aircraft Manufacturing
Murphy Aircraft of British Columbia, Canada established itself as a significant player in the kitbuilt aircraft market over several decades. The company's total production exceeded 2,000 kits across multiple aircraft types, including 850 original Rebel aircraft, 350 Super Rebels, 800 Renegade kits, and 100 Maverick kits. This impressive output positioned Murphy among Canada's most successful homebuilt aircraft manufacturers.
The company experienced ownership transitions in its later years but retained its manufacturing facility and workforce. New ownership planned to resume production focusing on the Rebel, Radical, and Moose models, with expectations of shipping up to 200 kits annually targeting the North American market.
Engine and Performance Specifications
The standard SR-2500 utilized a 186-kilowatt Textron Lycoming O-540-A4A5 air-cooled, horizontally-opposed six-cylinder engine driving a two-blade constant-speed Hartzell propeller. Three-blade propellers were available as optional equipment. The engine mounting system accommodated powerplants ranging from 134 to 224 kilowatts, providing builders flexibility in their aircraft's performance characteristics.
Fuel capacity totaled 227 liters in two wing tanks, with optional auxiliary tanks adding another 303 liters for extended range operations. This substantial fuel capacity supported the aircraft's intended role in remote area operations where fuel stops might be hundreds of miles apart.
Variants and Configurations
Murphy developed several Super Rebel variants to meet different operational requirements. The basic SR-2500 featured tricycle landing gear, while the SR-2500TD incorporated tailwheel configuration for improved rough-field performance. Both versions shared the same 250-horsepower Lycoming O-540-4A5 powerplant and fundamental airframe design.
The most significant variant was the Moose, originally designated SR-3500, which first flew on April 2, 2001. This version featured increased gross weight and offered engine options including the standard 186-kilowatt Lycoming IO-540 or the more powerful 265-kilowatt VOKBM M-14P radial engine driving a two-blade wooden propeller. The Moose was available only in tailwheel configuration.
Operational Capabilities
The Super Rebel's cabin accommodated a pilot and up to three passengers in two pairs of side-by-side seats, with an optional jump seat increasing capacity to six occupants including dual controls for training operations. The rear bench seat could be removed to maximize cargo capacity, accessed through a large port-side cargo door behind the passenger entrance.
With an empty weight of 771 kilograms and maximum gross weight of 1,361 kilograms, the Super Rebel provided substantial payload capability. Its 10.97-meter wingspan and 16.91 square meters of wing area delivered the low-speed handling characteristics essential for backcountry airstrips.
Legacy and Continuing Operations
Though production ended in 2008, Murphy Super Rebels continue operating in Canada, the United States, and New Zealand. The aircraft represents an important chapter in the homebuilt aviation movement, offering builders access to four-seat backcountry performance previously available only in expensive certified aircraft. Many examples remain active in wilderness flying operations, testament to the type's robust design and enduring appeal among pilots seeking adventure beyond conventional airports.
