An Ultralight Aircraft with a Big Plane Feel
The Maverick was built to conform to stringent Japanese ultralight criteria. It does that and meets the standards of several other nations as well, including Canada's Advanced Ultralight Regulations TPlOl.41. The Maverick has recently been accepted under British Section S regulations. In the United States it can be built in the experimental amateur built category or for use as an ultralight trainer. However it's licensed, the Maverick provides unrestricted fun for weekend pilots who want to go out and knock about the countryside.
It will do everything a J-3 Cub does, only better. It gets off quicker, flies faster, lands shorter responds to control inputs more aggressively and has the advantage of side by side seating.
Like the Rebel, the Maverick fuselage is all metal and features semi-monocoque construction for strength and simplicity. It goes together easily. Firewall forward is unique, because of the Rotax 503 installation, which is smaller than the Rebel powerplants. The engine weighs about 99 lbs., almost 200 pounds lighter than a Lycoming 0-235, yet there's plenty of power for fun flying. The Rotax 582 can also be used. The standard fuel tank is located behind the firewall and holds 6 (US) gallons, with the option of 14 (US) gallon wing tanks for additional range.
The gear is similar to the Rebel gear, utilizing a rugged aluminum V frame with half axles, 600-6 tires and shock or bungee cords that stretch to absorb shock on landing. The Maverick can be equipped with high profile tires for offairport landings as any open pasture will seem like an enticing runway with the low landing speeds of the Maverick. What little welding is required for the Maverick is done at the factory. The control stick, rudder and brake pedals are powder coated after welding is completed.
Space in the Maverick cockpit is roughly equivalent to that found in a Cessna 150. There is ample leg, head and shoulder room for two average size adults. Sling seats are comfortable, easy to install and lightweight. Doors are one piece and easily swing up and attach to the bottom of the wing. The instrument panel is large enough for a full compliment of VFR instruments. Visibility is excellent to front, sides and through the sky lights. Doors can be removed, weather permitting, to give superb visibility and that open cockpit feeling.
Maverick wings utilize three spars, all aluminum pre-formed ribs, and an aluminum leading edge that forms a "D" cell. The material used is 6061-T6 aluminum. Unlike the Rebel, the Maverick does not require a dozen stringers, since the wings are covered with fabric instead of aluminum sheet aft of the main spar, saving considerable weight and construction time. Ailerons are identical to the Rebels in construction, and are controlled by stainless steel cables. The wing tips are fibreglass to the main spar and connected by an aluminum tube to the trailing edge. The wing is braced with a single streamlined strut, attached by dual load path fittings.
The vertical and horizontal members of the tail group are formed using pre-bent aluminum tubing that's riveted together, covered with fabric, and held in place with flying wires. There is no welding. The elevator is controlled by a stainless steel cable that connects to the control stick and rudder movement is by stainless steel cable that connects to foot pedals with toe brakes. The tail wheel is a full swivel kick out style.
High Quality Construction Methods
When purchasing an airplane, one of the most important things pilots and builders are concerned with is the structural integrity of the craft. They like to know that they are flying a strong and safe machine they can trust. When comparing aircraft in this regard, the tale is told not only by the design criteria, but by the materials and construction methods. At Murphy Aircraft Mfg. Ltd., we pride ourselves on providing only the strongest and most structurally sound flying machines possible. Right from the stringent design criteria to the aircraft quality materials and sound fabrication methods, we have designed and built airplanes which surpass anything of similar weight and characteristics.
The high lift modified 4415 airfoil provides excellent climb performance and slow speed capability.
The wing is a three spar design consisting of a standard enclosed aluminum D-Cell with a fabric covered metal box section comprising the main body of the wing.
Ailerons provide an excellent roll rate and a high degree of controllability at slow speeds.
The fuselage section is a semi-monocoque structure formed by metal skins and pre-formed bulkheads.
The controls are controlled by high strength stainless steel cable which provides crisp, immediate response to control inputs.
The flying surfaces are covered with 1.7 ounce Polyfiber aircraft covering.
The motor mounts consist of 5/B"x .058 4130 chrome moly tubing, which provides excellent strength yet is light weight.
Lexan, a space age material is used to form the windscreen and windows.
The conventional tail dragger design provides excellent rough field capabilities.
Constructed entirely from quality 6061-16 aluminum which has an extremely good strength to weight ratio.
Dual hydraulic differential disk brakes on aircraft quality aluminum wheels with a choice of tires.
All fuselage and wing skins are both pre-formed and pre-stamped with all pilot holes. Ribs and bulkheads come pre-formed with guide holes pre-stamped. This makes the structure self-jigging. The skins can be clecoed to the ribs, then used as templates to drill the remaining holes. As a result, kit assembly is both easier and faster.
Stress tested to prove compliance with all major ultralight standards making It nearly universally acceptable.
