Flight, June 1929
BRITISH AIRCRAFT AT OLYMPIA
DE HAVILLAND AIRCRAFT CO., LTD.
FOUR complete machines will be exhibited on this stand, i.e., the D.H. "Hawk Moth" with "Lynx" engine, a standard "Gipsy Moth" land 'plane of the open type, a "Gipsy Moth"
coupe, and a "Gipsy Moth" seaplane.
Of the three "Gipsy Moths" to be exhibited one, the coupe "Moth," will be of the earlier form of De Havilland construction with plywood covered fuselage, and wooden wings. The other two "Gipsy Moths" will be of mixed construction in that they will have the latest type of D.H. welded steel tube fuselage and wooden wings.
The De Havilland type of wood fuselage is already well known, and it will therefore suffice if we confine ourselves merely to recalling that it consists of light spruce longerons and struts covered with plywood. This type of construction has amply proved itself in actual service over several years and has been found to be both strong and rigid and to require no rigging after leaving the factory. Beyond periodic cleaning the "Moth" type fuselage requires practically no maintenance work. Another advantage of the semi-monocoque construction is that repairs can easily be carried out anywhere and almost by anyone.
The wooden wings of the De Havilland "Gipsy Moth" are of normal type with spindled I-section spruce spars, spruce interplane struts, and internal drag struts in the form of steel tubes. The wings of all types of "Moth" are, designed to fold back against the fuselage, enabling the machine to be wheeled through a 10 ft. doorway and housed in a garage of normal dimensions. The folding gear is of the simplest type, it being necessary merely to swing the two jury struts into their sockets, withdraw four spring loaded locking bolts, and fold the wings back, locking them in position with special catches. The operation occupies only a few seconds. With wings folded a "Moth" can easily be towed along any reasonably wide road behind a flight car.
The Coupe "Gipsy-Moth" has been designed and introduced for those who prefer the protection against draught which the coupe arrangement offers. Already the coupe machine is becoming popular, and as it provides very nearly the comfort of a limousine at but small extra cost compared with the standard open type of machine, it is likely to become increasingly popular in the future.
The coupe addition takes the form of a roof and clear celluloid windows attached to the top of the ordinary "Moth" deck fairing. The view of both occupants is as good as in the open machine, with the exception of straight to the rear, and in addition to keeping out all draughts, the coupe considerably reduces the amount of engine noise which reaches the occupants.
Wearing of special flying clothes is unnecessary in this Coupe "Moth." If the occupants desire to use the inter-cockpit telephones, the earpieces of which are attached to flying helmets, the helmets may be worn, but other special kit is unnecessary. If desired, the coupe top can be supplied as a separate unit for permanent attachment to a standard "Moth."
The dimensions and performance of the coupe "Moth" are exactly the same as the corresponding figures for the open "Moth." The tare weight is, however, 925 lbs. in the case of the wood fuselage machine. The gross weights for normal and " Aerobatics " C. of A. are identical with those of the open type.
D.H. COUPE MOTH (D.H. "Gipsy").
A "MOTH" COUPE: The De Havilland Aircraft Co. has recently produced a variant of the standard "Gipsy Moth" by adding a small "roof" over the cockpits. The machine is not intended as a separate model, but for use in cold climates where some protection of the occupants is desirable. In the flying view the pilot may be recognised as Captain de Havilland himself, and the machine, G-AAAA, is his personal "bus."
THE LADIES!: (3) Mrs. A. S. Butler in her Coupe " Moth G"
LANDING IN THE DESPREZ CHALLENGE CUP COMPETITION: 2, Mr. Alan S. Butler, in his new D.H. "Moth Coupe" (85-h.p. "Gipsy"). Mr. Butler gained first place.
LANDING IN THE DESPREZ CHALLENGE CUP COMPETITION: 3, Captain Bayley on his Gipsy-Moth G-AADC
Основным заводским вариантом Gipsy Moth являлась модель "купе" - легкая конструкция из дерева и ткани. Фонарь кабины изготавливался из триплекса для защиты находящихся в ней. Также были построены две амфибии DH.60G.
Mr. Morris Jackaman's new Coupe Gipsy-Moth which has been supplied to him by Airwork, Ltd., Heston, Middlesex. It has been attractively decorated and daintily equipped, becoming the "last word" in private aircraft.

VARIOUS STYLES OF WING FOLDING: These photographs from the International Touring Competition indicate how aircraft designers of various nationalities provide for reducing space required for garaging machines. 4, shows the simple British way of folding, the machine being Broad's "Moth."
PROGRESS: Three generations of Moths at Haldon. The standard Gipsy Moth (left). The Coupe Moth (right) and Puss Moth (centre).

Mr. E. C. Brown demonstrating the Coupe Moth belonging to the Chairman of W. B. Dick and Co.
THE FLYING TEST: W. B. Rich are running their Moth on their mineral oil to give practical proof of its ability to do the job properly.
THE FLYING TEST: Last week we showed this Moth, and through a printer's error it was called the property of W. B. Rich. It does, of course, belong to W. B. Dick, the makers of the well-known "Ilo" brand lubricating oils, and their Moth is being used as a "test shop" for the mineral oil which is advised as being the most suitable for all such machines.
THE GIPSY MOTH IN FRANCE: The machine at the top of our illustration is the Gipsy Moth belonging to the Comte de Beauregard, a prominent French Private Owner, while the lower machine is M. Eloff's Gipsy Coupe Moth. Both 'planes are flying over the little Village of Toussus-le-Noble, near the Farman Aerodrome.
THE LEADER: Mr. Nigel Norman flying down the line before leading the tour to the Continent.

Mr. Pickthorn's "Moth" (Gipsy I), No. 51, showed most care in streamlining the fuselage. But the struts were faired into the surface with metal gaiters. (106-92 m.p.h)
THE ZENITH CUP WINNER: The De Havilland "Gipsy-Moth" on which recently Capt. Broad won the Zenith Cup Circuit of France in a day, at an average speed of about 112 m.p.h., is actually the machine flown by Broad in this year's King's Cup race. The cowling arrangements are a little unusual, and are designed to reduce air resistance.
G-AAHR. Special two-seater racing Moth with standard Gipsy engine. Winner of Zenith Cup, averaging 112 1/2 m.p.h., including all stops, over 1,150 mile circuit of France. Top speed 122 m.p.h.
