The Laird LC-EW was a six seat cabin sesquiplane designed for the industrialist George Horton. It first flew in 1934.
Many Laird aircraft were designated as LC (Laird Commercial). In most cases this was followed by an airframe code, here E and an engine code, here W for Wasp. The LC-EW was designed to an order from the industrialist George Horton, who had previously owned the sole Laird LC-AA, first flown in 1928. [1]
It was a true sesquiplane, with a lower wingspan slightly less than half that of the upper. Both wings were essentially rectangular in plan out to rounded tips. The upper wing was built around spruce spars with plywood ribs and fabric covered. Upper and lower wings were braced together with parallel pairs of wide spread, transverse, streamlined V-struts on each side. Their apices on the lower wing were immediately above the landing legs. Between the fuselage and the legs the lower wing was constructed of Cr/Mo steel tubing and aluminium alloy-skinned; beyond, its structure was the same as that of the upper wing. Aluminium alloy ailerons were hinged only on the upper wings, filling about half the span. The inner lower wing carried flaps of similar construction. Both upper and lower wings contained fuel tanks. [2] [3] [4]
The LC-EW was powered by a 450 hp (340 kW), nine cylinder Pratt & Whitney Wasp C radial engine driving a two-bladed propeller and tightly enclosed under a long chord, NACA cowling, though bumped out over the rocker boxes to reduce its diameter. Aft, the fuselage was an all-metal aluminium alloy structure with multiple frames, stiffeners and metal skin. The pilots, or pilot and fifth passenger, sat side by side at the front of the cabin and had dual controls, including a central Y-type control column. Radio was fitted, with an external aerial. The ventilated, heated cabin had three windows on each side and was entered by a starboard-side door; its four passenger seats had safety belts. There was a baggage compartment and toilet at the rear. [2] At the rear the tail was conventional with its cantilever tailplane at mid-fuselage. The tail surfaces were all metal constructions, similar to the fuselage. [2] The tailplane had a blunted triangular profile and carried blunted rectangular elevators. Fin and unbalanced rudder had similar profiles to the horizontal tail plans. [3]
Its fixed, conventional landing gear, with a track of 8 ft 10 in (2.69 m), had short, vertical oleo legs encased in fairings at the ends of the inner section of the lower wings. Each had a pneumatically-tyred wheel, also under a fairing. The castoring tail wheel was also on an oleo strut. [2]
Little is known about its short history in Horton's ownership. He died in 1935 and the LC-EW was bequeathed to the aeronautical department of the Rensselaer Institute. [2]

General characteristics
Performance
The Nieuport-Delage NiD 42 was a fighter aircraft built in France in the early 1920s, the first in a family of designs that would form the backbone of the French fighter force over the next decade.
The Stearman LT-1 was a late 1920s American biplane, carrying four passengers plus mail.
The Solar MS-1 was an American prototype all-metal sesquiplane airliner built in 1930.
The Nieuport-Delage NiD 590 was a three engine, high wing monoplane designed for policing and other roles in France's colonies, which did not go into production or enter service.
The Caudron C.570 was a French twin-engine aircraft designed and built by Caudron in the mid-1930s. It was designed to function in multiple roles; as a bomber, passenger transport, paratroop aircraft, cargo aircraft and air ambulance.
The Bréguet 25 or XXV was a French two seat fighter from 1925. It was heavily armed, carrying seven machine guns.
The Hamilton H-18 was a 1920s US four/five passenger aircraft. An early all-metal design, it reflected Junkers and Stout design practices. Though it won safety and efficiency awards only one was built.
The Laird LC-B was a three seat, single-engined biplane, built for private owners in the U.S. in the late 1920s and offering a variety of engines. About 35 had been built before production ceased in the mid-1930s. Two have been restored to flight.
The 1929 Curtiss Model 53 Condor, also known as the Curtiss Model 53 Condor 18 or the Curtiss CO Condor, was a civil passenger version of the Model 52 Condor bomber. A twin-engined biplane, it carried 18 passengers.
The McMullen Mac Airliner was a late 1920s American light airliner powered by a Liberty L-12 V-12 engine of World War I origin. The sole prototype was destroyed in a hangar fire.
The Neilson NC-1 Golden Bear, aka Neilson Coach was an American, three-place, high wing cabin aircraft, flown in 1929. It did not go into production.
The Wallace Touroplane was a late 1920s U.S. three seat, high wing cabin monoplane. About 20 were built.
The Hodkinson HT-1 was a U.S., eight place, three-engined sesquiplane, first flown in 1929. Despite an order for five, only one had been completed before Hodkinson Aircraft went bankrupt near the start of the Great Depression. It operated in Guatemala for several years.
The Ireland Privateer was a 1930s American two-seat, single pusher-engined monoplane sports flying boat which could be equipped as an amphibian. About 18 were built.
The Ireland Neptune was a four or five place pusher configuration biplane sold in flying boat and amphibian versions. Designed in the U.S. and first flown in 1927, well over 50 were built.
The Lincoln AP was a U.S., single engine, high wing, general purpose civil cabin aircraft first flown in 1930. Only four were built.
The Zenith Z-6 is a single engine biplane U.S. airliner built in the late 1920s. Its cabin, in the fuselage immediately behind its radial engine, holds five or six passengers depending on engine power. It is flown from an open cockpit further aft. Nine were completed and one has been restored to flight.
The Nicholson Junior KN-2 was a low power, high wing, two seat, cabin monoplane intended for sport or flight training in the United States in the late 1920s. Only one was built.
The Wilford Gyroplane was based on a German autogyro first flown in 1926. After E. Burke Wilford bought the rights and patents, it was developed in the US until 1936.
The Vought V-100 Corsair Junior was an attempt to produce a cheaper, multi-purpose, export version of the Vought O2U/O3U observation aircraft it had produced for the United States Navy. It did not sell, and only the prototype was built.
