Even with so many changes in modeling over the years, some things never grow old. These pages from vintage modeling
magazines like American Aircraft Modeler,
American Modeler, and
Air Trails captured the era. Whether you
are here to wax nostalgic or for the history, enjoy your visit. I will be glad to scan articles for you. All copyrights are hereby acknowledged.
Here is the article on the history of the Lockheed Sirius that I electronically scanned from my purchased copy of the April 1973 American Aircraft Modeler magazine. Patricia T. Groves is the author. All copyrights (if any) are hereby acknowledged.
There were actually two separate articles, one that presented plans and a construction article for an R/C version of the Lockheed Sirius, written by Mr. Maurice F. Philips, and the other this history lesson.
Lockheed Sirius History
Many variations of one plywood fuselage were created by Lockheed. The most famous low winger is the Sirius.

After Charles A. Lindbergh entrusted h is beloved Spirit of St. Louis to the Smithsonian in May 1928, the Mahoney-Ryan 'Company generously replaced it with a brand-new Brougham B-2. In these and others whose owners or builders were eager to have him demonstrate, Lindbergh wound up as that year's most conspicuous user of airplanes. With the media reporting nearly every passing mile, America's No. One aviation booster did extensive personal and goodwill flying while managing to squeeze in the survey flights he was doing for several air transport companies. Buckled into a wide variety of airplanes, an outstanding (for 1928) 65,000 miles passed under his wings.
By summer 1929 Lindbergh was actively looking for an airplane of his own choosing that would be better suited to his current preoccupations. And, when he attended that year's National Air Races in Cleveland, he was still looking. Also at the August 27th to September 2nd meet was Jerry Vultee, the saucer-eyed chief engineer for the Detroit Aircraft Corporation's month-old acquisition, the Lockheed Aircraft Company of Burbank, California.
When the two met, Lindbergh mentioned h is search for a high-performance, long-range plane. While noting the advantages and disadvantages of various configurations, he stipulated the safety aspects of low-wing, wide-wheel base, quick takeoff and an all-around good visibility. Then with a current project in mind, Vultee whipped off a few preliminary sketches for Lindbergh to consider, and made arrangements with the popular flier to meet with Lockheed's new general manager, Carl Squier, under less hectic conditions than an air show.
Predecessor to the Sirius was the Explorer. This plane was developed for transoceanic flights but accidents marred its success.
Charles and Anne Lindbergh in their Sirius are followed by a Vega full of enthusiasts. Note the Vega is an especially early model.
From this concrete mold built in 1927 came Lockheed's wooden wonders-The Vegas, Air Expresses, Explorers, Siriuses, Altairs, and Orions-among the great planes of the Golden Age of Aviation.

As it happened, Lindbergh's specifications fit an airplane then being developed in the Lockheed shops. Earlier that year a young ex-flying service officer named Harold Bromley dropped in looking for an airplane capable of transpacific flight. The 29-year-old pilot was one of several hardy fliers who hoped to cop the $25,000 Tokyo Asahi (newspaper) prize for the first non-stop flight (either way) between Japan and America. With Tacoma, Washington money behind him, Bromley toured West Coast aircraft manufacturers, including the two-year-old aircraft company in Burbank.
At the time, Burbank was an obscure little burg surrounded by farmland which extended up to the nearby distinctive Verdugo Hills. On an industrial zoned parcel of ranch land the tall, cone-shaped brick chimneys of the Empire China Company provided the most distinguishing feature around. The next largest building on the lot was jointly occupied by the Mission Glass Works and the Lockheed Aircraft Company. Scattered about the patch were several unimpressive sheds and out-buildings, a ranch house now serving as Lockheed's office and an airplane hangar which stood alongside an unharried gopher-infested dirt flying strip.
At this point Lockheed's advertised line of aircraft consisted of two model types: A high-wing Vega which was gaining in popularity with the flying fraternity; a parasol wing Air Express, designed as a mail and passenger carrier.
Bromley walked through the door of the small red brick "office" and into the kitchen cum Lockheed Engineering Department. Introducing himself to the entire department - Vultee and the company's two draftsmen, Jimmy Gerschler and Dick Von Hake-the flier laid out his requirements. Later, still discussing the possibilities, Vultee took Bromley in to meet Allan Loughead, the company's co-founder and general manager. Afterwards, Bromley toured the plant's wood and metal shops, the assembly and service areas, all yet under the command of Tony Stadlman, another of the company's originators. While activity was apparent, it was hardly a high pressure operation.
During the tour Bromley spied an unfinished fuselage stuck off in an outof-the-way corner. Looking as though it had been cut out to accommodate a lower wing, he asked about it and was told that it was a relic of an experiment begun by Jack Northrop in the "old" Hollywood plant back in '27. The beginnings of a low-wing job for Hubert Wilkins, the project was abandoned when the Wilkins group unexpectedly ran out of money. Then momentarily considered the following year as a seaplane, it was hauled out only to be shoved aside again. Although designated an Explorer, there'd been little or no engineering done on it. And "thar she set" until Bromley walked in.
To Bromley the altered Vega fuselage had possibilities. And over the following weeks he, Vultee, Gerschler and Von Hake finished off the engineering. (More custom-built than mass produced, buyers of Lockheed airplanes, like expectant fathers, labored alongside the production crews.) By June 18, 1929 the first Lockheed Explorer rolled off the line with a low wing-extra long, broad and straight with no dihedral. (Basic fuselage construction was the same as with the Vega. See August 1970 American Aircraft Modeler, page 16ft.) A single-seat open cockpit was placed just forward the empennage which had undergone several cut-and-dry design Changes. The tail unit at this point having a rounded fin and a squared-off rudder. Flight tests proved satisfying, and Bromley flew home to Tacoma to begin his dash across the complacent Pacific.
On Sunday, July 18, 1929, the big Explorer, its latent power buried under garlands of flowers, was christened the City of Tacoma by two little girls representing the U.S. and Japan. Finally, cheers of thousands ringing in his ears, the young airman shoved the throttle to the firewall to begin his run. Within seconds cheers turned to screaming pandemonium as the glistening orange Explorer wobbled into the air-then crashed.
Overlooked in the joyous frenzy of the day, the fuel-topped off to capacity in the early morning hours expended as the sun rose higher in the summer sky. When Bromley made his run, it slopped over in his face and blinded him. The aviator tried desperately to recover, but couldn't. Barely before impact Bromley managed to flick off power, thereby preventing a fire and saving his life plus those of the panicky spectators running toward him.
Still willing to back his efforts, the Tacoma group put up new financing, and Bromley returned to Burbank with enough salvage to mother-hen a second City of Tacoma. (Although Lockheed now was under Detroit's command, the same easy-going atmosphere prevailed.) Bromley and Vultee worked out several new changes to the second Explorer; however, this aircraft, too, came to grief. Subsequently, a third City of Tacoma was laid up incorporating engineering modifications that had come about as a result of the recent Lindbergh order.
The requirements of the Lindbergh aircraft had evolved enough, by now, to designate the new model name of Sirius. The same length as the Explorer, the Sirius, however, had a slightly shorter more slender wing with two degrees dihedral built in. Two single-seat open cockpits tandem were placed forward a classically high rounded tail which added a foot to overall height. Fitted with a 450 hp Pratt & Whitney Wasp, wheel pants and the NACA cowl, the airplane was painted in the high-contrast colors of black and orange.
Typically, Lindbergh was on hand every possible moment during the building of the Sirius. Then in January 1930, after testing by Lockheed pilot Marshall Headle, Lindbergh accepted it. Introducing the 2974-lb. bird to his petite wife Anne, the three got acquainted. Over the next four years, the Lindberghs and their Sirius were seen all over the world. And, although these survey flights presented some of their most demanding work, their flying missions together provided the couple their most precious moments of privacy. At this point In their lives the big Lockheed was a second home and sanctuary.
During 1934 the Sirius, by now known as the Tingmissartog, was donated to the American Museum of Natural History. When it later moved to the Smithsonian, the Tingmissartog - registered NR-211-joined the Spirit of St. Louis - registered NX-211. The following year Lindbergh's sentimental attachment for the 211 N-number was then transferred to a Lamberg 0-145 Monocoupe which he kept for about six years before donating it to the Missouri Historical Society. Although it never participated in any particularly note-worthy flight and he wasn't overly fond of it, Lindbergh donated it to assure the preservation of a type of small aircraft constructed in St. Louis during the Thirties. Referred to by him as "the Lambert," it's now on display at the National Museum of Transport in St. Louis.
Ultimately, 14 of the wooden Sirius were built more or less along the same lines as Lindbergh's model 8. A fifteenth was built in Detroit using an experimental all-metal fuselage.
Twin cockpits tandem provide the most noticeable difference between the Sirius and the single-seat Explorer. Sliding canopies added to the Lindbergh aircraft after a few month's trial became a standard accessory in all Sirius models. The slightly heavier Sirius 8A differed from the original 8 in having a larger fin and rudder area and an additional four in. added to the fuselage length. One aircraft in the 8A series was fitted with Lockheed's first fully retractable landing gear. Originally intended for the Lindbergh Sirius, the prototype gear turned out too wimpy. By the time the necessarily re-engineered wing (which later evolved Into the Altair model Lockheed) was ready, Lindbergh had already exchanged the standard gear for Edo floats.
Construction Of the Sirius C was typical of the methods of the day where each individual Lockheed was an individual built to individual specifications. The C differed in that forward the cockpits, a close two-seat cabin was included.
Nearly a year later the easily adaptable fuselage was again re-engineered into an air transport progression. First referred to as a Sirius six-passenger cabin plane, as the designs altered, the name was changed to Altair Model 9 before it too progressed enough to merit its own model name-type of Orion.
By making optimum use of the one basic design, Lockheed's 30-ton concrete mold turned out the distinctive, easily identifiable Vega, Air Express, Explorer, Sirius, Altair and Orion. With nearly every aircraft altered and changed, adapted and modified, stripped down or jazzed up to suit the requirements of their owners, each wooden Lockheed was an individual in an era of individuals.
