.\cw World KrronK Su n d a y , O ctober 9th was a momentous day for both Italy and New Zealand. Flying from the hills at Paraparaumu, three miles North West o f Wellington, Ian Barber set a new radio control glider duration record o f nine hours four minutes with a Frank Bethwaite Mk. V 72in. design, using Wright radio gear operating rudder and a g in. wide elevator trimmer. Ian had been wailing two years for this attempt to be made, when a true west wind provided best conditions. The glider was launched at 06 : 31 hours and the flight had to be ter­ minated at 15 : 35 hours due to a low cloud base, the Tommy Meyer’s U.S. Nationals winning Locning, made from A.P.S. original intention being to go on to make the record a plans, poses with a degree of realism (which we feel should not be 12-hour figure.

LuH iy Hilary! Seventeen-year-old apprentice electrical draughtsman Gary Richardson from Horbury, near Wakefield in Yorkshire, was minding his own business when starting a Davies-Charlton Bantam -049 in his Mercury Agrcssor delta at the British Nationals this year. He was not to know that his photograph (along with many other D-C engine users) had been taken while enjoying his aero- modelling. Consequently, one can appreciate his surprise on seeing his picture in the September advertisement for D-C products, coupled with the offer to have an all­ expenses paid trip to the Isle o f Man factor)'. We were able to join Gary in his fascinating week-end at the beginning o f October, and also enjoyed the Sft “ lucky Gary!'* Harry Hundleby and magnificent Davies-Charlton hospitality. A ride around Hcfin Davies greet Gary Richardson at the the famous Island course for Tourist Trophy a.id D-C works.

His own Bantam was rev-checked on the well-equipped lest bay and new projects demonstrated in the experimental department. Travel on BEA’s hardest-worked and second-oldest Viscount in service, G-AM OG, helped to make the trip his greatest ever thrill. Gary is sure to he at next year’s Nationals most ready and willing to be photographed.

L i wmch was illustrated in a ground shot last month, d c irly shows the additional identification roundels applied to the tailplanc upper surfaces for obvious reasons. The aircraft was flown on t o t in Great Britain and needed to be protected from possible mistaken identity A Maurice Farman S .ll Shorthorn, one of a batch of one hundred (A2I76-A2275) built by the Whitehead Aircraft Co. Ltd., of Richmond. This particular machine was completed about November of 1916. The Shorthorn was used extensively in initial pilot training and many a pilot could relate remarkable escapes from injury in heavy landings. It was. however, a Rigger's nightmare for re-assembly as can be well appreciated by study of this photograph at left which shows the multiplicity of struts and bracing wires

Like the Sopwith Salamander illustrated last month, t*-is Armstrong Whitworth F.K.3 was used in experiments with camouflage. A number of readers have written to comment on the exceptional photograph of the Salamander and we have no doubt that this F.K.3 will arouse similar interest. The original photograph shows a large diameter roundel on the upper star­ board wing, almost of full chord whilst the smaller diameter roundel can just be seen, outlined in white on the port wing. The roundels were, however, symmetrically disposed with centres in line with the aileron inner ends. Like the Salamander, all camouflage patterns on this F.K.3 appear to be outlined with a darker tone but have been more indiscriminately applied on this larger aircraft. The F.K.3 was normally used as a trainer and was said to be a viceless aeroplane, capable of all the acrobatics known at that time in the early war years

L e ft: A Pine photograph of a standard Sopwith I j-Struttor. probably built by Ruston, Proctor and Co. Ltd., seen here without the pilot's Vickers gun. On the original photograph, a letter B is just discernible in the centre Pin bay and the serial RPS4ISCC at the base of the white rudder stripe. Both the roundel and fin markings have been lamp blacked for night werk, note also the black painted engine cowl, often left polished on the production I j-Strutter B elow : Unusual features of this Martinsyde G.I02 Elephant arc its single exhaust outlet well forward, and the Aldis gun sight. The aircraft appears to have the usual Lewis gun above the centre section. It is one of the Pirst machines in the batch numbered A393S-A4004. Th; Elephant, was unofficially so named because of its size far a single seatcr.

B elow : A Sopwith Dolphin with a crash pylon added to the centre-section structure. The Dolphin could carry twa Lewis guns on the front spar member of the centre section, b it in this case a single Lewis is mounted on the crash pylon. The run has only a 47-round ammunition drum in place of the usual 97-round magazine. Two Vickers guns are mounted above the engine to fire through the airscrew. Powered by a 4S h.p. ABC Gnat two-cylinder horizontally- opposed engine, the P.V.8 Eastchurch Kitten is seen (R ig h t) in its Pinal form with a fixed tailplane as distinct from the original all-moving elevator. Its upper wing span of only 18 feet and length 14 ft. II in. made it one of the smallest aircraft of W orld W ar I and the intention was to operate the Kitten from Torpedo Boat Destroyers, flying from a small take-off platform. A single Lewis gun was mounted above the upper wing centre section. Only one aircraft was constructed and tested during 1917 although a slightly different predecessor, P.V.7, was also constructed

3 Important notin' ►

With an infinitely powerful engine, a model could reach the speed of light. It would then be infinitely massive. If it were flying, its gravitation would pull the earth so that the earth would spin into it. W e all know what happens when models spin in. and think how much worse it would be if the earth spun in. So the S .M .A.E . should make a rule prohibiting the use o f infinitely powerful engines.

What we like about the "Cloud” is its modernity. Name a feature that has meant success in sing e channel and the “ Cloud” has it. Thick symmetrical tailplane, rearward two-wheel u/c, Warren braced fuselage structure, D section nose spar on the wing and easy equipment access are all there. Moreover, they’ve catered for single, 4, 6, or 8 channel equipment, giving mods, for actuator instead o f servo use, and details for ailerons for the ambitious. This is truly a universal kit. very well produced with loads o f die cutting, and one which we are currently enjoying immensely. T o h l ) l i m it i- | m i |»oN«‘ u n i t Many will have noticed the Cobb Hobby Micro 4 and Micro Controller combination advertised in our columns, and have perhaps been most enthusiastic at the possibility o f gaining more work from a single channel outfit. The Micro-4 servo is the part which actually goes in the aircraft (or boat) to operate the control surfaces, and works on a pulse counting system like all compound actuators, but this motorised layout has a clever electrical braking circuit whereby overrun, a common failing: in some motorised compounds, is eliminated. The selection o f control position is effected by wipers and dead spots on rotary printed circuits. Actual movement o f the control surfaces is via cam-operated horns which protrude, one cither side, from the servo. While the pulse sequence could be mastered with practice using a micro switch, the Selector 4 “ think box” eliminates the necessity o f complicated sequence pulsing. This unit is physically similar to Micro 4, but has a “joystick” which is moved to position whereupon the electric motor-driven mechanism, which acts as a switch plugged in the Tx despatches the appropriate number of “ blips” . This signal is picked up by the Rx and relayed to the Micro-4. A full wiring diagram o f all possible hook-ups is supplied and demands full study before any attempt is made at installation. We should warn users o f a misprint in the instruction leaflet. The tags B & C on the Micro-4 should be reversed, C for B. This occurs only in the details for the test hook-up, with the Selector 4 connected directly to the Micro-4, and this is the system used in our test rig shown in the photographs. As with the actual flying rig (when the controller is plugged into the Tx) the controller must be slower than the Micro-4 and for synchronisation a 10 ohm pot. is best linked up to the controller between the white wire and the battery. While we would emphasise that this system is not a substitute for multi-channel R/C since it is virtually impossible to pulse a control surface, it does offer most Using a Revmaker type proportional servo (March '59 A/M) this 54-in. desirable attributes for the man who wants extra con­ Heath Parasol by Walter Hartung of Detroit Balsa Bugs looks '!ke an ideal scale subject.

T eam race enthusiasts have been admiring Dennis Nixon's smart fuselages this season. The Hinckley Club models have also shown their worth in the contests. This feature describes how Dennis tackles the problem o f using gluss fibre to obtain such attractive and strong models. (See photographs below and right) When considering a control-line model fuselage, for glass fibre moulding, the first thought must be for the installation o f engine and controls. Dividing the fuselage into two halves horizontally (giving a top and a bottom half) is the obvious way to provide for easy installation, and the photo and following sketches, instructions, relate to a team race fuselage; however the only modifi­ cation for a free flight or radio fuselage is that the division into two halves could be vertical giving left and righthand sides. fuselage should appear as smooth and fine as that in Having finalised on the shape and dimensions o f a the photo, by Dennis Nixon, and from the above fuselage half, a pattern can be made from a block of descriptions it might appear that glass fibre fuselages deal or similar hard wood, and should be made to the are a simple matter. But this is not so; a considerable exact limits o f the outermost shape and size o f the amount o f experience is required to produce a really fuselage. Sawing (bandsawing if possible) is the easiest beautiful moulding, and a basic knowledge o f glass method o f working the block down to the rough size o f fibre and resin methods is required to produce a moulding the pattern, after which chiselling and glasspapering with o f even poor quality, as quantities o f hardener, catalyst the aid o f templates will provide the finished article. etc. arc very precise and arc interdependent on the type The smoothness of this final finish cannot be over­ o f resin used. An example o f the misfortunes that can emphasised, for even the smallest flaw will be magnified beset the amateur is that if too much catalyst be used, on the fibre fuselage.

A n e w u s e for old engines? This idea which we have taken from the U.S.S.R. modelling magazine shows how one can make a starter using one of the elderly long stroke diesel engines no longer considered up to date enough as model power units, yet still good enough to be used to start another engine. The diesel is given a generous flywheel and drives a second shaft by spur gear, the end of which protrudes from the case with a rubber connector tube to engage a model spinner. This tube is clamped to the shaft and it will be seen that a handy starter thong is kept in the carrying handle to get the diesel going. M ( M a 660 December, I960

Prior to this, most Indoor modellers were concentrated in the areas surrounding the few remaining Blimp Hangars. Now only ore or possibly two Blimp Hangars in the entire country are available to modellers and these only on rare occasions. Indoor modelling recently received a much needed shot in the arm with the announcement by the A M A Contest Board that effective from November 1st I960, A M A National records for Indoor models would be recognised on the basis o f ceiling height. With the renewed interest being shown in this class o f modelling during the past year, the A M A Free Flight Contest Board bowed to the wishes o f the modellers and the following categories have now been established: Records set in rooms having a ceiling up to 35 feet in height; records set in rooms having a ceiling between 35 and 100 feet in height; records set in rooms having a ceiling over 100 feet in height. All current A M A Indoor records will stand and will be considered as having been set in the over 100 foot category. Under the new set-up, no change in model specifications will be made and thus it is hopedtoattractmore converts. December, I960 661

Even so, the times were quite respectable, first being Jan Kriz with 847 seconds who led eight other new names into the leader­ ship with the top “ expert” down at tenth place. The following day, fair weather blessed Wakefield and Power, again many new names being included in the results but Power was won by the well known Rudolf Cemy with a perfect 900 score, and Wakefield by Kalina with 880. After dealing with the bad weather contests, it is a pleasure to mention that the fifth and final event in the long series o f F.A.I. Championships held in Finland took place on October 2nd at Turku in perfect conditions. Since the overall result o f the year’s competitions had already determined the top men in Power, the leaders did not compete; but in A/2 with the theoretical poss- ibili’ y o f three men having a chance to defeat Tahkapaa WORL on his home field, there was considerable excitement.

F rom our many thousands of pages, we can only select a few to illustrate milestones of progress in both the worlds of publishing and Aoromodclling. What we reproduce here will perhaps remind those who have been ardent readers since the fir it issue of important stages in their own aeromodclling career, and our younger readers may appreciate news of developments before their time. Reading round our border from left to right, we start with the first-ever issue, dated November 1935. Printed in red and blue it announced a simple 3 ft. beginners’ design by Charles Burchell, with construction in Birch and piano wire. Balsa was only considered strong enough for the tailplane tips! Same issue also included scale details o f the S.E.5—then a mere youngster of eighteen years, compared with the elderly twenty- five year old Spitfire in this issue. The fine scale drawings, by Leonard Bridgman arc typified by the set for the Sopwith Dolphin, seen next, and used in April 1936. Same issue included first-ever mention of a clockwork mechanism being used to time an engine run, and a feature on professional modelling with a description of the Woodason workshops. W e jump next to 1947, and the first British Nationals, held at Gravesend Airport, now a housing estate. This was the year of post-war boom in enthusiasm, of the introduction of successful control-line flying, of nylon for covering, of Copland's first post-war streamlined Wakefield and jet powered free flight models. In February 1944, AEROMODELLER published first jet pro- tulsion ideas employing turbine from engine exhaust or direct fnduction turbines, perhaps still not very practical, but never­ theless possible experiments. The Spitfire, then by far the most advanced aeroplane in the R.A.F. was featured as a giveaway plan in December 1939. This IS inch span rubber-driven model was made in thousands. Major Bowden wrote on flying boats, Peter Chinn on latest fighters and bombers, and the editorial spoke of ’‘war-tim e" policy and aeromodclling carrying on ns usual. Came 1946, and on April 20. the great opening of Britain’s first and only model aerodrome at Eaton Bray. The pages illustrate its large area, alas too soon and too adventurous a project. The Hawker Hurricane was a giveaway feature of December 1938 issue, with plans actually printed in camouflage colours! The fabulous 40 c.c. flat four engine Lysander (total weight 20 lbs.) was described; we find the Baby Cyclone 6 c.c. complete with mount at £4/7/6 and kits from 1/9 upwards. In January 1938, D. A. Russell's famous 16 lbs. G-ADAR low wing, ply covered petrol model was the talking piece. Plan shows multi-star structure. Engine was an 18 c.c. Comet. Another milestone was J. F. P. Forster’s first description of practical radio control, the circuit serving well nowadays to illustrate the pitfalls of ambition. December 1941 and the war very much a sobering influence; but AEROMODELLER was bright as ever with a reminiscent cover, more information on the fabulous Lysander still under construction and plans for A. F. Houlberg’s Isis which had won the Gamage trophy for two consecutive years. Star Models kitted for a mere 5/6d. J. Van Hattum’s Sparrow Hawk from March 1939 issue—a model destined to start many an enthusiast on the hobby but probably not as startling a beginning as the L. H. Sparcy feature on diesels created in December I94S. This was the first revelation of diesel charac­ teristics, and an article destined to start many a manufacturer thinking. Finally, with resumption of the Wakefield Trophy International Contest in 1948, AEROMODELLER conducted a historical round-up of past winners in March of that year, illustrating winning models from 1928 1939 670 December, I960 I

W ith C hristmas comino fast upon us, now is the time to think o f gifts for other modellers and what to buy for oneself with that present money. Why not start by sending for a catalogue ? Carnages new edition o f their 132 page fully illustrated catalogue is still only I/· and contains as complete a list o f the plastics available in Britain as can be found anywhere, plus useful little features and illustrations o f all the major kit manufacturers’ products. The Stanley catalogue No. 26. issued by Stanley Works (G.B.) o f ShctTield, is one which is issued free on enquiry (quote A eromodeller) and gives a complete synopsis of all their famous tools from block planes to screwdrivers, including many which arc useful to the model maker. I f you arc in doubt as to what to ask for fo r Christmas, this is the book which might give you the right idea. Then not to forget Avrumudi'ller Plans Service Plans Handbook (l<>4 pages fully illustrated) covering our vast range o f many thousands o f different model designs plus many useful articles, only 2/- from our address. New kits off our test bench arc illustrated on these pages. From Λ. A. Hales we have the Swiss design which has been so popular for instructional classes and design work in that country and which for its simplicity plus efficiency will become a favourite here. The Yeoman KO II spans 50 inches and retails at 19. M including P.T. Kit goes together easily and there are actually spare ribs supplied in the die-cutting for repairs. A small modification we advise is to sheet over the wing centre section to take the retaining rubber bands. A. A. Hales is also sole agent for Graupner in Britain and among recent kits from this German manufacturer we have enjoyed building is the Sifentius for Micromax power. This is more fully described in our just-released edition o f the A eromodeller Annual for 1960/61. so it will suffice to say now that Silent lus is a remarkable model more than fulfilling its manufacturers’ claims. Another German line imported by A. A. Hales is the all-plastic Dux Test Pilot ready to fly control-line design which is virtually unbreakable and capable of loops. For British distribution. Davies Charlton have co-operated and produced the Super Bantam 049 with special radial mount and incorporated tank, whilst Dux have made in turn a special cowling to fit the Bantum. This is likely to be the first o f several innovations in the plastic rcady-to-fly market for Britain. Also new from the Isle of Man factory are the 7x4. 8x4 nylon props at 2 4 and 2,6 respectively which will suit I to 1-5 c.c. admirably for sport flying and 2*5 contest work.

Left: At top Graupner Silentius with large two-blade folding prop, a special design for Micromax electric power. Next, the Yeoman KO II glider, has many practical features and first-dass building gen. Next. KeilKraft’s Snipe with a Cobra 049 shows its sheeted fuselage and cabin wing mount. Below it is the K-K Conquest glider, a simpleton for the novice, and at bottom the latest Oavies-Charlton nylon props in 8 x 4 and 7 x 4 sixes.

Snipe is 40-inch span, retailing at 19/9, while for the smliter purse their simple sheet-sided Conquest 30-inch span glider sells for 7 11. As c m be seen from the photographs, both these designs arc by Neville Willis. For control-liners, Kcil Kraft have introduced the Firebird, a 32-inch Combat/Stunt model for 2-5 c.c. or 3-5 c.c. engines, flapped and lightweight at 17 oz. (with an Oliver Tiger) to make it a very hot performer that should satisfy the most ardent enthusiast. An accessory from K .K . is their new glow plug clip in pressed metal with an insulated connection for the block top terminal which will sell for 3/6. Still on our board is the Mercury Cobra, a 401-inch profile stunt design for 29 and 35 engines which threatens to be a fast flyer with ns weignt o f 28 oz. and 355 sq. in. wing area. The plan for this model is a stage-by-stage well-produced illustration o f prc-fabricated part assembly which gives some indication o f the high degree o f preparation in this kit which includes plastic wing tips, and sells fo r 28/6. From Frog we now have the M e 109 and Hurricane to join the Spitfire in their 18/9 profile Combat scries, plus an attractive little sheet fuselage free (lighter, the Nimrod, for -5 to *75 c.c. at 17 6. We hope to give more details of these next month. Turning to bigger models. Performance Kits’ 54-inch span Pinnacle at 76'7 is a lot of model; in fact, the airframe complete with -29 engine and tank weighs 34 oz. before covering. This design is definitely not for the man without some experience iti miking control-liners for it presumes knowledge of control installation (no holes in ribs for lead-outs) and cowling detail. Ours has a ducted cowl with an outlet under the nose for cooling air. We should warn constructors to save the off-cuts from the spars as they are needed for m ikin g the fin. The Pinnacle has been most ably demonstrated by its designer in National and local competitions for it to need no further emphasis on the score of performance. F.d Johnson tells us that he will soon have the American Top Flite kit for the Orion multi-channel radio model which won the World Championships. This kit costs $27.50 in the U .S.A. so is likely to be expensive, but for the money one will get no less than 132 pieces o f complete hardware and fittings, copious die-stamped plywood and balsa parts, formed landing gear and a 12 x 6 prop. Swedish radio control kits o f note arc detailed in our Radio Control Notes feature this month, but wc must comment here on the pre- fabrication of parts especially so in the Viking, one of the really outstanding low-wing designs which has often graced our columns in photo reports o f international competitions. The photograph at right illustrates what we mean as far as the tail block, cowling parts, etc., arc concerned. Distributed by Ripmax, the 60-inch Viking sells at £6 12 6 and the 57-inch high wing Vagabond at £6/5/0. JYet more radio kits (what a shame they all have to be o f foreign origin) are now readily available. Henry.I. Nicholls has the Berkeley range in stock including the Astro Hog at £8 10/0; Impulse, an ideal single-channel model, for I ·5 to 2-5 c.c. at 42.6; and the Royal Rudder Bug at £4/5/0. H.J.N. also has the latest de Bolt kits for the low-w ing Pursuit multi-channel at £7/19/6 and the popular Custom Live Wire biplane at £8/15/0. For our money, the kit o f the year for design and clever adaptability o f pre-fabrication is Phil Smith’s Phoenix from Model Aircraft (Bournemouth), more popularly known as Vcron. This 60-inch glider has an elegance one used to expect o f kits, but which is now so often lost to the demand for lower prices and simplicity, yet assembly of Phoenix is simplicity itself. Some might consider it to be pricey, but Vcron will find a lot of buvers more than ready to spend their money on such a model which offers a shape which could not be duplicated by 95 per cent, of today’s acromodcllcrs from stock block strip and sheet, and which is robust, goes together perfectly and will fly beautifully. Two well-known modellers have made important moves in tfe model trade in recent weeks. Georjjc Fuller is now appointed General Manager for A. A. Hales Ltd., having grown up with the company to its new impressive modern and large establishment at Potters Bar, while Alex M cDonald is now Sales Manager for Radio and F.lectronic Products. For nine years Alex has been a main stay on H .J.N .’s staff o f representatives and he now takes with him the best wishes o f the Holloway Road establishment and all the wealth of experience that implies, to act as Liaison Officer between sales and manufacturer of R.F.P. products. This will relieve George Honnest-Redlich for development and production. A much needed arrangement now that R.E.P. equipment is in such demand from all parts o f the world. Glow plug developments arc taking place all the time. Davies- Charlton will shortly be announcing their Quickstart plug with a new element and plugs with idlcbars arc on their way from another source. Arthur Nlullett is importing the American O.K. Glow-Trol plug with a ceramic liner to sell at 7/6 and this plug promises longer life and a greater promise of keeping going when most needed in those radio flights.

The most interesting feature is of course the fuel system from Ed’s specially modified O.S. Max 15 engine. His tank is vented only through the Ed Miller with two of his tube which faces the open mouth of the carburetter and when the models before the Cran- tinier is set, as in the sketch, this vent is closed by squashing the rubber field contest last August, tube.

This is now in widespread inter­ national use. but care should be taken to see that weight loads arc not distributed loo far out to the tip. Those who query the trailing edge droop on the airfoil section for the wing will be interested to know that Ed uses this droop to slow the glide and produce additional lift, without apparently, any ill effect on the very fast climb pattern.

There were certainly some hotter engines than are Actually, this is no joke. I have seen the model go indicated for a particular year. The wing area could just that high. With a top performance design it is quite vary, but there was an optimum. Two important trends possible to climb too far into haze, or clouds, or the are revealed. Obviously the duration would increase with centre o f a hot thermal, and disappear before recording an increase in HI*. Second, as UP increases, so does a maximum.
