A New Heritage
The Murphy Moose a truly functional aircraft that was designed with the first time builder in mind - a builder who demands the highest quality and value for the dollar and is unwilling to compromise comfort and function.
The Murphy Moose was designed in response to numerous builder and prospective customer requests to handle the 360 HP M-14P radial engine. The Moose is offered as a taildragger only and support~ a useful load ranging from 1,600 to 1,800 lbs.
If you choose to mount the M-l4P on your Moose, you will be the proud owner of an aircraft that not only looks like its distant cousin, the de Havilland Beaver, but also will sound and perform like one too. There are few things that make pilots stop and look, but a radial engine starting up will always have that magic. Regardless of which engine you choose to install, the Moose has excellent flying qualities, impressive performance and unparalleled utility!
A Fantastic Bushplane
The two large main doors, removable seats, seat rails that double as cargo tie downs, plus the standard extra large cargo door, make the Moose a real utility plane. The huge cabin interior (two inches wider than a Cessna 180) easily accommodates bulky or long loads such as bikes, skis, furniture, lumber, 55 gallon drums, or camping supplies. The Moose can even accommodate a class of parachute jumpers or be used as a photographic platform with the baggage door removed.
Hard points for floats are standard and the wheels are adaptable to oversized tires for short, rough bush strips. You can fly almost anywhere carrying just about anything you want. This is a kit aircraft with great performance and airframe strength, the ability to carry a load and room to stow it ... one fantastic bushplane!
The fuselage utilizes semi-monocoque construction. Bulkheads are stamped 6061-T6 aluminum and are self-aligning with the side skins. A sub-floor is installed over the lower bulkheads providing a solid base and a flat floor for storing cargo. The cabin area is built over two immensely strong longitudinal spars providing a clean floor from the firewall to the back of the cargo area (120 inches). This cantilevered floor makes it possible for the Moose to have large cabin doors giving easy en tty and exit. Two high back adjustable bucket seats are provided up front and a wide based bench seat in the rear can be replaced with optional bucket seats for total control over your seating arrangements.
The back seat gives ample leg and shoulder room, and together with the optional large side windows and cabin skylights, rear seat visibility is excellent. Optional seat upholstery kits in fabric or leather is available in many different patterns allowing you to customize your interior.
The centre of the floor has an access tunnel that run, from the forward cabin to aft of the cargo area. Fuel lines, brake lines and controls are concealed beneath the floor in this tunnel. Loads can be tied down with no fear of jamming controls or interfering in any way with the normal operation of the Moose. The cargo area is cavernous with easy access to the back through a massive cargo door. With the back seat removed, the cargo area increases substantially allowing you to carry almost anything you can pickup! Alternately, add the optional rear jump seat and turn your Moose into a six seat crew cab. Flight tests have shown that the Moose flies the same with or without the cargo door in place, for those who might enjoy skydiving or removing the door for photography.
The wings are a very straight forward design. The modified NACA 4415 airfoil is a time proven profile providing a large centre of gravity range. The wing has a constant chord with no washout, which yields reliable stall characteristics and simple assembly. The wing structure consists of three spars (front, main, rear), 12 stringers and 16 ribs. The stringers help the wing skins transfer torsional loads to the rest of the structure. The leading edge is .032, allowing for countersunk rivets (if desired).
The first three bays at the root of each wing constitute the Moose's fuel tank holding up to 30 US gallons per wing. The builder has the option to expand the fuel capacity to either 40 or 50 gallons per side for increased range. Wingtips are pre-molded fibreglass with light aluminum sub structures. The wing is supported by a single custom extruded strut with a 1 1/2" x 1 1/2" x 1/8" square tube running through its length - another fail-safe fitting.
All attach points on the wing are fail-safe (as are all major load bearing members). They are constructed of multiple parts ... should one part fail the other parts continue to maintain structural integrity.
Ailerons and flaps are simple, strong, and easy to assemble. They consist of a main spar (which is pre-punched for rib location), pre-formed ribs and a one-piece formed skin . As with the rest of the kit, no jigs are required and the assembly can be completed in less than 10 hours. This procedure is similar for the elevator and the rudder.
Control surfaces on the Moose are mass and aerodynamically balanced. This is for two reasons: a mass balanced surface is very resistant to flutter and aerodynamic balancing allows us to perfectly harmonize the control response.
The Moose will make you feel at home from your first flight.
Horizontal Stabilizer and Fin
Both horizontal and vertical stabilizers are cantilevered and employ stringers to transfer torsional loads. The horizontal stabilizer has a constant chord with a symmetrical airfoil. Like the wing, the stab is a three-spar design with the fuselage picking up fittings on the main and rear spars. The skin is a one-piece pre-formed aluminum wrap-around.
The Moose continues the versatility theme with a range of available engine options. Whether you are regularly carrying heavy loads or operating from restricted strips or simply enjoy the peace of mind of American power, the big, smooth running 6-cylinder 0-540 series from Lycoming is for you. Need a little more power, the I0-540 keeps the smoothness but adds a little extra for those hot days. Murphy Aircraft can sell you a factory new Lycoming engine at special OEM prices that may surprise you!
Want the ultimate in performance and looks? Go for the Russian M-14P radial engine generating 360 hp. that will make that take-off at gross weight look like child's play! Optional configurations bring the power up to 400 hp too! Maybe it's the lure of a radial engine starting, puffing smoke or the need for the ultimate power source, either way the M-14P will make your Moose stand-out on the ramp.
The Murphy Moose offers the builder an all metal 4 to 6 place kit aircraft with great performance, unequaled carrying capacity and versatility. There are no special skills required to build the Moose and its system of pre-punched matching holes assures a perfectly aligned finished product.
The Murphy Moose is a joy to fly and will provide you with many years of pleasurable,safe flying.
