The speed range is such that in flight the plane is at all times equal to any emergency and responsive to the controls yet the low ending speed and flat glide is not sacrificed for speed.

No attempt has been made in the design to achieve high speed whereas everything has been done to increase the climb. We believe that quick climb, to the subordination of everything else, is the desire of every commercial pilot. Experience with small field in the average plane is very convincing in this respect.

The performance of the Waco 5 regardless of ground conditions has been thus far unapproachable. Its short run, rapid climb and speed range has been agreeably astonishing to a great number of pilots. 

Tests of the machines' speed show that with the motor turning 1450 R. P. M. it is capable of a speed of 80 M. P. H. and that straight horizontal flight may be maintained throttled down to 1050 R. P. M., an important point when the life of the motor is considered. Under these conditions it is quite easy to run at least 300 hours without an overhaul. The climb with pilot alone is 800 feet per minute and with a full load of pilot and two passengers 500 feet per minute. Four may easily be carried altho there are seats for but three. On ordinary ground the average takeoff is between 250 and 300 feet and the run on landing considerably less. In stunting the machine has displayed remarkable alertness to control and confirmed the strength of sustaining and control surfaces.

The speed range is amazing 30 to 80 M. P. H. and the controls are alert throughout. Landings are slow and gentle due mainly to the high lift being maintained at angles very much in excess of those ordinarily utilized with other wing curves, thus allowing the speed to decrease with increased incidence without stalling. Figuratively speaking the Waco 5 "takes off a dime and lands on a stamp."

Main Planes
The main cellule is comprised of four main planes and a center section panel. The spread is 33 feet with a 5 foot 6 inch chord, staggered 10 inches. The dihedral is three degrees. The curve is a new high lift curve of thick section developed to meet the requirement of maximum efficiency and is of sufficient thickness to allow of strong light beams. A noteworthy characteristic is the minimum translation of the center of pressure throughout the useful range of incidence angles, which together with a decalage of two degrees is largely responsible for the stability displayed. The spars are of rectangular section spruce. The ribs are of the Pratt truss type, constructed with spruce battens and struts and gusseted with mahogany plywood. The weigh only nine ounces yet are capable of withstanding a distributed load of over 500 pounds, a remarkable strength to weight of ratio. The entering edge is covered with mahogany plywood. The trailing edge is oval steel tubing. The internal wiring is with 8 ga. wire. Sidewalks 12 inches wide extending to the trailing edge of the panels are provided and are an asset when ease of getting passengers in and out is considered. All wood work is given two coats of waterproof varnish, metal parts two coats of durable enamel. The wing covers are made from Grade "A" government specification mercerized cotton and are finished with five coats of dope and three coats of spar varnish.

Panels are made interchangeable, a very important point in maintenance or repair. Should a panel become damaged, the user can either repair the panel himself, a procedure he will find easy, due to its simple construction, or he may obtain one from the nearest distributor. We believe that no aeroplane having non-interchangeable panels, whether built in sections or continuous throughout the entire spread, offers the necessary facility of repair required of a real commercial aeroplane. Waco ailerons are interchangeable either up or down, right or left.

The cellule bracing consists of but one set of struts and one bay wiring. Fittings are stampings from nickel steel, enamel finish. Wires and turnbuckles are lackquered for preservation against weather. Four large ailrons are hinged to the rear spars employing a semiclosed gap. Aileron frames are spruce reinforced with mahogany plywood. Three equally spaced hinges are used and a very simple and direct aileron control is used, employing steamlined steel tube, inter-aileron struts. All control wires are exposed and easy of inspection and repair.

Fuselage

The fuselage is a wire girder construction and every care has been taken its design to admit of ease, of maintenance and repair. The motor mounting is such that the utmost accessibility is afforded to every vital part of the motor. Special provision has been made to allow of draining gasoline and oil and earburetor cleaning. The motor controls are simple and di [[underlined]] rect [[/underlined]] The radiator mounting and connections are the result of practical experience. The gasoline feed is from a 22 gal. tank in the fuselage. 

The fuselage is 36 inches wide at the passengers' compartment. Ample leg and arm room is provided. The pilot's seat is very comfortable and his compartment roomy. yet his vision is not impaired, due to the shape of the cowl being such that he can see directly ahead along the side of the fuselage, easier than in most ships with a narrower fuselage. The cock-pit rims are padded and leather covered and leather seat cushions provided. the pilot's dashboard contains all necessary flight and motor instruments. Dual control, although not standard equipment, can be provided. Ample baggage space is provided under the front seat. the front cockpit is provided with large celluloid full width windshield and the pilot with an adjustable triplex glass shield. The turtle back is of sheet aluminum as is also the rest of the cowling and is finished with black enamel.

Chassis 

The chassis is the essence of strength and simplicity. This component is readily demountable as a unit, or individual parts may be disassembled with a minimum of inconvenience and disturbance of adjacent members. Practically all the parts are removable through the agency of quick detachable nickel steel lock pins of large diameter. The chassis is composed of two sets of substantial steel "V" struts of streamline section combined with a pair of steel spreader tubes attached at the apices of the paired struts, and an improved wheel and axle assembly. The whole unit is cross-braced with heavy cable and corresponding turnbuckles and fittings. The axle is of large diameter with heavy wall reinforced at points of greatest load. The shock absorber cord is laced over and retained by belled spools of demountable construction. A feature of the chassis design is the fact that shock absorbers may be made up to length and then applied to the chassis. The wheels are 26 inches by 4 inches. 

A tall skid of conventional design protects the rear of the machine. It is mounted in a very novel and secure manner and operates semi-universally against the tension of the rubber coils. The skid is shod with a hardened steel shoe which is secured in place by bolts and is readily replaced when worn out. 

Empennage
The tail consists of a moderately double cambered fixed horizontal stabilizer of high aspect ratio to which are attached the elevators, the fixed vertical fin and the rudder. The design enables the units to be quickly assembled. The stabilizer is built up with spruce bars of liberal dimensions and spruce ribs suitable spaced and is cross braced with 8 ga. wire. The fin, rudder and elevators are of steel construction throughout. All steel parts are joined by brazing. No welding operations are employed in the construction of the machine. The tail group us so secured to the fuselage that all drift, control thrust and vertical loads are adequately provided for. The finish is identical with that of the main planes.

Our Policy
This organization believes that the progress of aviation, commercially at least, is dependant upon giving every pilot a fair chance to assist in selling aviation to the public by making a success of carrying passengers, financially as well as otherwise.

We believe that hedge hopping aeroplanes of war time design and construction are obsolete and must give way to a plane of advanced design and performance. We know that aeroplanes will be sold in quantity when they sell cheaply but cannot be sold cheaply unless sold in quantity, if the manufacturer insists upon exacting a large profit from each plane. We are depending on quantity production for our profit. We have enough confidence in aviation and in our organization to await financial returns in large volume for several years if necessary. 

We believe that the company which produces and sells the greatest number of good, cheap aeroplanes in the next few years will eventually predominate the aircraft industry.

In order to achieve this position we are producing a good ship; we are selling it at as low a price as possible and we are furnishing service and spare parts at proportionate prices.

We believe in the ship we are building and know that it will give you results. Our organization has both the ability and the desire to serve you as you have never been served before.

Terms of Sale
Purchaser must make an initial payment of one third of the purchase price with order. Balance upon delivery. Delivery of planes will be made upon the flying field of The Weaver Aircraft Company or its distributors. An additional charge will be made on all planes shipped to cover crating.
