A wealth of authentic detail makes these two planes H.204 F0CKE-W0LF ‘CONDOR' 12/6 wonderfully accurate A successful conversion from civilian use. the Focke-Wulf Condor served the Luftwaffe in reproductions of their World War II as a bomber attacking British convoys far at sea. Powered by four B.M.W.— Bramo engines, the Condor had a service ceiling of 19,000 feet; maximum speed of 224 miles famous originals. per hour, normal range 2.210 miles and flight endurance of 14 hours. The Condor—a civilian airliner that the Luftwaffe converted to use against the North Atlantic Convoys. The Phantom II—-which beat most of the world’s existing speed records when it was first in production and is now under order for the RAF. As you build them watch them come to authentic life under your fingers. They make worthy additions to the ever-growing Revel I range of models, a range that has something for everybody.

OPENING the £4 .10s. (including purchase tax) kit for thus long awaited Radio Control design gives an immediate impression of completeness. Undercarriage is pre-formed, sponge rubber wheels o: acceptable weight and a metal 'clunk' tank are items of hard­ ware that tlie lone modeller really appreciates. As for the wood, this too is well prepared with a pre shaped leading edge for the wing panels and all parts cut ready to push out and assemble. Being a KK traditional kit. utilising lon­ gerons and covering rather than sheet structure, the ‘M ini’ also brings with it a fair bundle of square strips. These need to be sifted to obtain four cental strength length): for the longerons. Plans and in­ structions are good, l ittle is left to the imagination.

London, this is a 2 hr. 12 min. film and will fascinate 1 jil U M w r m all aviation enthusiasts, blending rib-tickling humour with a sincere appreciation of the efforts made by those gallant pioneers in the earl/ days of flying—definitely not to be missed by any aeromodcller ! Scale modellers should also not miss the "Mag Men" model contesc at Old Warden. Biggleswade, on June 27th. DRAMA Emilio Ponticelli played by Alberto Sordi (the Italian entry) is dramati­ cally rescued from his burning Blcriot in mid-air snatch by the gallant American pilot Orvil Newton, played by Stuart Whitman in the closing stages of the great race from London to Paris. Ponticelli has already crashed a Phillips multiplane, Passat Ornithop- ter and Lee-Richards annular biplane, so he provides plenty of excitement for the cinema-goer in this epic film.

ACTION The fated No. 11 an Eardlcy-Billing biplane entered by the German High Command and flown by Colonel Man­ fred von Holstein (Gert Frobc of “ Goldfingcr” fame), is about to touch down according to the book of in­ structions at the Dover check point. Unhappily No. 9, the Demoiselle flown by the amourous Pierre DuBois (Jean- Pierre Cassel) and other entries are in the line of landing. This is one of but many exciting examples of skilful piloting to be seen. DUNKING Von Holstein loses his book in a hilarious scene when it is snatched from its fuselage rest by an antagonistic seagull. Anxious to recover the manual in order to know what to do next, the Prussian pilot upsets the applecart when he approaches the tail end and winds up in this attitude, eventually treading water whilst hanging on for dear life . If you want to see more spectacular flying and brilliant air-to-air photography, of these magnificent replicas, you’ll just have to go to sec 20th Century Fox Films Co.

MAINLY CONCERNING \ ( TRADE NOTES NEW PLASTIC KITS f A neat trio from A irfix this month arc the H.P. 42 Heracles', CA 13 Boomerang and a Bell P&Q Airacobra. I he Boomerang and the Airacobra are both to l/72nd scale while the Heracles is produced at I/144th and de­ spite this, builds up into a line 'medium-sized' model. We built up two Airacobras, one as the prototype aircraft and the other in the colours and marking of No. 60! Squadron who were briefly equipped with these machines. We chose aircraft ΛΗ-601 as our subject which, as well as being the Wing Commander's aircraft enjoys a serial No. coincidental with the Squadron number. As far as actual construction of these kits goes, little need be said except, perhaps, to add that the tricycle undercarriage layout demands nose weight to ensure a reasonable three point stance. Cockpit side windows were a little uicky and required careful handling with tweezers anil accurate use of cement, but otherwise the kits went together easily. Strips of Scllotape were used to mask oil the fin and rudder on the prototype model and matt colours were applied carefully to represent the National striping. Purists should attend to the excess of rivets and the tail profile. Price of the Airacobra is 2/-. I’hc Commonwealth CA 13 Boomerang, again 2/-, also goes together quickly and easily, and the markings and colour details supplied by Airlix are accurate for an air­ craft of either Nos. 4 or 5 Squadrons R.A.A.F. in opera­ tion in New Gt.inea. Solomon Islands and Borneo. Ours, the white tailed Qi -I ·. depicts a machine ol No. 4 Squadron R.A.A.F. and was painted as per Airlix*s in­ structions. A tlrcc part wing, with lower wing halves and centre section as a single moulding ensures accurate alignment of wings with fuselage, but the resulting gap between upper wing halves and fuselage definitely required filling. Undercarriage is also fairly Tiddly*, but when finally in position, looks nice, delicate and realistic. The Boomerang kit has 31 parts. Last from Airlix is the ‘Heracles* and just to be dif­ ferent we cho:.c to build ours as the impressed ‘Helena’ of 1940. This machine, originally the properly of Imperial Airways was taken over by the R.A.F. as a detached transport duties aircraft with No. 271 Squadron and car­ ried the Serial AS 983. This aircraft ended its eareci when it was dismantled at R.N.A.S. Donibristle in December 1941 following an accident the previous year when a motor had cut on take off. Although the damage was repaired it is doubtful whether the machine ever flew again. Airfix's model is one of the nicest we’ve seen and goes together extremely smoothly. For the tricky job of biplane wing construction, a jig is supplied with the kit to ensure correct alignment of upper and lower surfaces and the otherwise difficult job of strut positioning, etc., is sim­ plified. Colours for the impressed ‘Helena’ are dark earth and dark green camouflage patterned upper surfaces and matt yellow undersurfaces and struts. The yellow con­ tinued up the fuselage sides to a line just below cabin windows and the name 'Helena* appeared on both sides of the nose in black lettering. .Serial was also in black on both sides of rear fuselage. Large R.A.F. reel, while, blue flashes were carried on the under side of both upper wings, outboard of the struts, and roundels appeared on the upper surfaces, fuselage sides and underside of lower plane. Price of Airfix’s superb 74 part kit is only 4/6d. —the value is remarkable. Two new' “ Trailblazers" have arrived from Frog. They are the I).II. 60(V (tipsy Moth and the DJI. 88 Comet Racer both in I /72nd scale. Hie Moth. G-AAAH Amy Johnson's famous ‘Jason' in which she became the fir>t

Also the accurate Revell F-4 Phantom in U.S. Navy mark­ ings which is accurate right down to the blunt tail leading edge. Excellent value at 8/6d. the Phantom lends itself to markings of all three U.S. forces plus modification to Fleet Air Arm and Recce versions.

Talking of coverage. Hi mbi-r On produced a special Camouflage enamel pack at 2/6d. 1 his contains six phials of the standard matt colours, yellow, white. Dk green. Ok earth, “ sky” and black. We have given the manufacturers our own opinion of these and understand that the yellow is to be darkened in tone lor at the moment it is far too near primrose than ochre to meet the approval of any cx-Air Force man's memory. The other colours lend also to be lighter in shade than our own carefully preserved various coloui snips but we must say that they are the closest yet to the true colours as used on bombers and trainers throughout the 2nd World War and lighters of the 1938-40 period. Those who care to motorise plastics will be interested to learn of the new Mabichi “ Baby’* motor which idles wonderfully on 1.5 v. and will slip inside a wide range of models particularly those with radial engines. Distri­ buted by Ri I'max at 5, 6d. the motor can be built into most plastics quite easily. Also from Ripmax what we thought at first (o be just anolhei ready-to-fly model in the ‘toy’ category turned out to be quite different.

I'he Comet Racer, 2/(>d. as is the Moth, is one ol the easiest to make plastics we have seen. All parts are beautifully smooth and wing tongue anil tailplane. etc., arc superb. We coloured ours in matt light blue with dark blue flashes around spinners and dark blue registration. f inally, a new one from Ri vi.i i the McDonnell / u i-1 rhantom II. This is a superb model in every way and its size at I 72nd scale when compared with the Gipsy Moth for instance, needs to be seen to be believed.

The leading edge too should be fairly light, though do not choose brittle wood for this and the trailing edge which can be medium soft grade. Strength in the fuselage is important, so choose medium wood here and shape it down to reduce weight. Construction is begun by cutting the leading edge, trailing edge and ribs from sheet. Cement ribs to bottom trailing edge, add leading edge top and bot­ tom and plane and sand to fit front piece.

AIRCRAFT DESCRIBED Number 143 Cunliffe-Owen

A l k o n a u u c s is a curious subject of recurring in­ terests, The range of experiment in the first quarter century o f successful powered flight was such that whatever appears this year or next w ill owe some­ thing in its originality to an early attempt no matter how obscure. Not all the ‘new’ ideas come to a successful re-development stage. Swing-wings, vari­ able thrust swivel knozzles. ducted fans are exceptions. Now the pendulum swings to the lightweight struc­ ture with exceptional lifting capacity and leading British aero-technical magazines draw recent corres­ pondence in their columns to the efforts o f Vincent Burnelli. Ordinarily we would not have given this seemingly •dead' project more than a cursory study, yet when our files revealed the detail in these three views we began to realise how the Burnelli “ lifting fuselage*’ or “Thick wing” conception is so very suitable for any flying scale project free flight or radio control. So. with no more excuses, here is one twin en­ gined type in which the close proxim ity of the en­ gines and simplicity of structure offer a minimum of design and operational difficulties. Outset of the engines would take care of assymctric power output, aided by inset or ‘toe-in’ of the vertical tail surfaces.

This 1939 view of the Cunliffe Owen U.B. 14.B test flight from Eastleigh, Southampton, where it was made reveals the extended and thfekened centre section which formed the 15 passenger cabin. 331 July, 1965

Next, came the larger, 90 ft. version French A ir Force. Commercial prospects were C.B.16, an advanced design created fo r the U.S. Banker P. W. Chapman. Retractable undercarriage air conditioning and a kitchen were advanced features for 1920. The U.B.

Then came the U.B. 14 in 1934. reduced in size to 71 ft. span but short lived as the original crashed with incorrectly fitted control cables in January 1935. During W.W.II efforts to produce Burnelli trans­ ports were unsuccessful and the XCG-13 glider, al­ though superior to the comparative CG-I3A. did not enter production. Vet one more Burnelli wing was made, when the Canadian Car and Foundry Co. pro­ duced the CBY-3 in 1946. This 86 ft. machine first appeared as CF-BEL-X and then became N17N when in Florida in 1^52. then YV-X-ERC in Venezuela.
