i D o n ; M c H a k i j ’ s G i a d i a i o k which m ade its debut at this year’s Nationals has been the object ot many a scale tan’s request over the last six months. In m pristine silver colour scheme, with 72 Squadron markings it has attracted a great deal ot’ attention wherever down, and .ts characteristic flight with the muffled exhaust note coming through genuine scale pipes have made it both look and sound the part ot the last of the famous Biplane fighters. Here is a subject for the ardent scale enthusiast who wants perfection or the man who has made a model or two and would like to tiy his hand at scale It is a docile model, and one which will achieve great populaiity in years to come. i s ; I All constructional details are given on the plan and provided they are carefully followed no difficulty should be encountered. The sheeted front part ot the fuselage .an be covered in wide sheets of -in. medium balsa as there is very little double curvature present, moisten the outer surface of the wood to facilitate bending. Joins between sheets should be arranged to come over the keels and Ji-in. sq. stringers. Λ slow -drying adhesive of the la* Pages f'V \ type will be found to be of great assistance during this operation. Araldite was used on the original model for all hardwood jointing such as undercarriage ply fairings and motor bearer fixing, strength is enormously increased and the extra time required for drying is worth while. A sliding cockpit cover is, of course, optional, but adds considerably to the final appearance The cockpit may be completely equipped and a dummy pilot included (from soft balsa) as desired. Details will be found included in the 3-view drawing in our "Famous Biplanes” feature. The exhaust system is also optional, but il used is very effective and also helps to keep the model clean by leading surplus oil cut of the motor cowling. Covering on the original model was heavyweight Modclspan, although in view of the light weight of the finished tub, silk will be used when recovering becomes necessary Silk covering will increase the "hole resistance” con* (( aittiniii

In li Yugoslavian, Radovan employed an ingenious means of wing shift for trim with the 50 gramme or a heavier motor.

George Reich of I'.S.A. had another system for the same purpose on his Wake field, using movable wing pegs as in and other interesting features of his design w ere the change to triangular section aft, to save weight, and the use of a clockwork D,T timer, so accurate it could be used to check the flight time.

Five blades for greater efficiency and better auto-rotation. These can he quickly and easily made from solid sheet balsa and I recommend a flat bottom section with the leading and trailing edges sanded to form a cambered top surface. Alternatively, a C lark Y or symmetrical section is effective. For rotors used in the smaller type helicopter, a thickness of ;,·* in. is about right, while for a larger diameter, it is necessary to use A in. The blades should be finished well with fine sand paper and protected with two or three coats of dope. Larger rotors are best built up with leading and trailing edges and covered with the sheet balsa or heavyweight tissue. For best results, it is necessary to mount the rotor blades free from propeller’s down wash and I find cycle spokes, or fairly still' piano wire the best means of attachment to the hub. Bolt the wires to the huh, using 6 o r S B.A. bolts, this being a very convenient method of allowing the blades to he folded for transit purposes when slacked off. The blades should he secured firmly by lock nuts and washers when flying, otherwise they will work loose in flight. An added advantage of this method is that should the rotor blades hit any fixed obstruction when in flight, the blade is less likely to suffer damage due to the swinging action of the wire arm. 'The counter-weights are required to change individual blade pitch and act as a governor system. As the revs, during auto-rotation are down as compared with the power run, the blades rest against the bottom stops which should be adjusted to ensure a slight negative angle. This setting should be such that the model descends steadily, if it does so in a jerky fashion then this is a sign that too much negative setting has been used. A too rapid fall with side slipping and slow rotor K.P.M. is a sign that the negative blade angle is too small. The counter balance weights can be conveniently fashioned on wire supports using plasticine, lead foil, or solder. The weights will then be just sufficient to up the blades to rest on the droop or bottom stop. Blade hinges may he conveniently made from tin-can stock; equally effective is a portion of Woolworth curtain wire. F i i M d a g t 1 A silhouette type of fuselage works very well on Sikorski, Sycamore, Skeeter or original shape, made of thin sheet balsa, having a card disc or fin to give weathercock stability. It must be realised that the propeller and motor downwash have a strong effect, so it is important to minimise fuselage drag. 1 have found for best results, especially in windy conditions, an open type fuselage of light construction to be far superior and the plans given of two recent reaction-type models show this p attern . A wire or bamboo landing chassis is all that is neces sary for light models, and the wheels, if used, can be permanently fixed as vertical T.O. requires no forward motion! Many of the writer’s models use oak-apples or acorns in this connection! When starting R.O.G. flights, the model should be held until the rotor attains steady and maximum revs, otherwise, except in a dead calm, the model will drift and topple over when partly airborne.

These units invariably incorporate dead shaft projecting from the tear of the fuselage. segments in the large gear wheel via leaf contacts This assembly produces a tail assembly that is quickly similar to the Ellis Canadian actuator described a year or two back, or the system described by Mr. Ford of Brighton in the August, 1958, issue. Sellotape is invariably specified as the dead segment which to Mr. 'Pucker seems a makeshift. He drills holes in the gear wheel at the appropriate points, squares them off with a small tile, chamfers the edges of the hole from each side to form a key and then fills them w ith “Bondaliller”. This when set produces a rock hard surface and the job finally needs rubbing down with a sheet of emery cloth. “Bondafiller” is manufactured by our old friend Peter Smith of Croydon and is available in powder form together with a resin in convenient sized packs from any good model shop. December, 1958 667 m m m CM·, traiiftitttor Η|ΐιίρηκ ιι< The ICditor was fortunate enough to acquire a while back a sample of the C.G. single channel tone modulated radio control equipment produced by the C.G. Electronics Corporation of Albuquerque, New Mexico. The C.G. RT-1 Receiver was the first all-transistorised tone receiver that we have experienced and is com pletely satisfactory in operation. It has been examined by experts such as Dave McQuc and Ted Sills who were impressed with the circuit design hut in particular the layout and miniature components which result in a receiver measuring only li in. x 2] in. x I in., weigh ing 2 ounces and operating ofT one 30-volt 11.T. battery. Idle current is 1 *25 milliamps, rising to 5 milliamps on signal. T h e carrier frequency is 27*255 M /cs. and the modulation frequency 300 to 600 cycles. The photo graphs demonstrate the very neat and compact layout, not forgetting the printed circuit, details of which are given for the benefit of home constructors. Id is one turn loosely coupled to L2 which is 7 turns of 22 s.w.g. All resistors are 10 per cent. £th watt and capacitors of 0*25 />/ and above are sub-m iniature electrolyrics with polarity as indicated. The H.F. transistor used in the SB100 (surface barrier type) is quite an expensive item. It is, we believe, limited to - 5 v. max. supply, which is taken care of in this circuit by the 47K-10K dropping chain to Tl. TRl is the super- regenerative oscillating stage, TR2 the tone amplifier. TK3 is driven into conduction by tone. TRl and TR2 have current stabilisation against transistor spread and temperature variation by using emitter resistors and feeding the bases from voltage dividers. Temperature limits are 130 deg. l· . to 32 deg. l·’. Ninety-five per cent, modulation is required for this receiver which is provided by the C.G. Ύ12 Trans mitter as illustrated. Tins very neat hand-held unit, weighs 3$ lb., is crystal controlled, operates at 135 volts ll.T. with a power input of 1A watts. Unmodulated it draws 5 milliamps and with the modulation key on 9 m illiam ps. T h e crystal is 27*255 M c/s. overtone type and the unit provides plenty of range although using a 54-in. telescopic whip aerial. As with the receiver a printed circuit is employed which is on the inside face of the transmitter assembly panel (see photo right). The price? Transmitter is 33·95 dollars, receiver 39*95 dollars, which totals in sterling approximately /.25, and we emphasise that it is not available in this country. Readers may well ask why we should therefore whet and then frustrate their appetites. The answer is that we publish this information to enable enthusiasts to build their own versions and trust that its publication will, at the same time, give British R/C manufacturers some ideas!
