So I dont normally do airliners (boring round tubes), but i saw this and couldnt help myself, Ag1 if you fancy more elvevator control, fly with pitch and yaw primarily (roll would knock the passengers sick), anyway its v close to the scale size, now the wiki bit:

The aircraft was designed between 1929 and 1932 with the idea of showing "what the intercontinental air liner of 1940 will be like."[4] Geddes developed the overall design concept while German aeronautical engineer Otto A. Koller provided the engineering expertise as Geddes was not a trained engineer. The two had clashed over Airplane Number 1 in January 1930, after Koller had described it as "an absolute[ly] undesirable design." Koller then declined to provide performance specifications for its replacement, Airliner Number 4, which Geddes intended to include for publicity purposes in his upcoming book Horizons (Little Brown, New York, 1932).[5] Geddes devoted over ten pages of the book to the project, including a fulsome endorsement of Koller's skills as an aircraft engineer on page 111 and detailed cut-away plans of the aircraft. Although uncredited in Horizons, the striking illustrations of the aircraft may have been drawn by the young C. Stowe Myers who had his first job in Geddes's office and was tasked with creating the illustrations for the book.[6] Designed as a V-shaped monoplane with nine decks, large capacity, viewing galleries, and public areas big enough to hold an orchestra, Airliner Number 4 was intended to replace the ocean liner[7] and Geddes wrote that, "Passengers aboard this air liner are able to move about as freely as on an ocean liner, enjoying recreations and diversions similar to those which seagoing passengers are now accustomed."[4] If built, it would have had a wingspan of 528 feet (161 m) and a capacity of 451 passengers plus a crew of 155. Power would have been provided by twenty 1,900 horsepower (1,400 kW) engines with six in reserve.
