The kits are also designed to cut building time drastically — get you afloat quickly. Both models feature ready-formed hulls and other parts in tough, smooth ABSplastic, plus die-cut balsa and ply parts ready to install. No chance of going wrong, either, with the detailed ‘Quickbuild’ plan and a separate profusely illustrated instruction booklet. Beginner and expert alike will appreciate the care that has gone into producing these kits. £24.95 GRAUPNER OPTIMIST £63.65 A round bilge yacht with a scale appearance and truly excellent sailing characteristics.

The sail winch and rudder servo do not experience shock, so the rubber mountings can be replaced by nylon bushes. Features to aim for in the design of the radio chassis: 1. Lightness; radio gear, batteries, sail winch, rudder servo and chassis should weigh under 13oz. 2. Lead the receiver aerial away from the battery pack or shield it in an aluminium tube. 3.

Battery pack to be easily changed but reliably held. 6. Centre of gravity to be as low as possible and on the centre line of the boat. The most popular rudder servo is undoubtedly the Futaba 17M, it is powerful and practically waterproof. A smaller lighter servo is the Futaba 30M used in radio cars; although | have used one successfully at meetings, | have returned to the 17M for the extra arm length and power. The more expensive RC transmitters have a facility for reversing the servos, but for equipment that does not, you should check with your local model shop because the servo direction shown in linkage Fig. 1 is different to that in Fig. 2. The advantage of the second linkage is that less effort is required from the servo when the rudder is and rudder servo. The wiring through the four pole on/off switch is shown in Fig. 3. The Mklill Andrews winch runs off 7.2 volts and will emit 6 volts for the receiver and rudder servo, making the wiring much simpler as Fig. 4.

Solarfilm is thin and easily damaged but like the other two easily replaced. The high density polystyrene should be stuck with Dunlop Clear from Halfords. Most other glues including Bostick Clear will attack the polystyrene. Trappers, Seahorses and Sea Urchins have grp decks moulded to the hulls. Mast and rigging Simplicity should be the aim of the beginner, do not embark on jib twitchers and rotating masts until you have achieved reliability of rigging, sheeting and rudder control.

Council normally moved into February this E isk in January was of reasons mostly related to year, for a number the ability of key officers to attend; in view of the weather during much of January, it was perhaps just as well. Despite a fairly full agenda, this was probably the most straightforward meeting for many months, much of the business consisting of reports of, usually, fairly non-controversial nature. Fixture lists for 1982 will be ready shortly (probably before these notes appear) and will in fact be booklets containing a list of club secretaries and much other information as well as the regatta list itself. Ken Shaw has put a lot of work in on them and not the least of his achievements is virtually to cover the cost of printing by selling advertising space. As mentioned previously, as each club pays its affiliation fee, a supply of these lists equal to the number of affiliated members will be sent, so that not only will every member have his own copy but he will know that the secretary has sent in the requisite fee. This is important since national regatta entries will not be accepted from clubs who have notre-affiliated, and there are of course some early meetings this season. One of the earliest is (was) the Model Maker Trophy at Bournville, brought forward to March 27/8, followed a couple of weeks later by the RM Championship at Cleveland on April 10 — 12i.e. over Easter. Following the weight of opinion expressed both at the A.G.M. and in correspond- ence, it was agreed that this Championship’s results would form the basis of selection for the World Championship in July; R10R selection would remain dependent on the results of a special race meeting to be held on April 25 at the Leicester club’s water. If any skipper should qualify for both he will have to choose in which class to sail and the resulting vacant place will go to the next in line of the relevant list. Similarly, if additional places are offered by the French organisers, the next in line in the appropriate results list will be offered the opportunity of entering. The entry fee per boat is, incidentally, F250, or about £23 at current rates of exchange. The O.0.D. for the Cleveland RM regatta, Eric Nuttall, submitted a draft of his proposed instructions to skippers, from which several points emerged. One is that the O.0.D. must follow M.Y.A. rules except where unusual circumstances or physical conditions force a departure. This arose mainly in connection with that hardy annual, whether skippers should be able to walk the course or whether they should remain roughly in one spot. A lot of people are puzzled by the rule allowing skippers to move over 30 yards minimum, feeling that this should be maximum, and it has always seemed rather surprising that power boat multi-racers can control eight or so boats moving at 40 m.p.h. plus over a 200 yards 284 course without moving from their pits while some yachtsmen want to scramble along the bank, which in some places can be quite hazardous. Walking is a comparatively recent innovation and in many people’s view has done nothing to make racing better or easier — quite the reverse, at times — while the effect of a lot of shouting along the bank must give the public a strange idea of model yachting. However, that is a digression. The other principal discussion centred round race nu mbers on sails. Undoubtedly large two figure race numbers on the jib simplify scoring, but the attachment of adhesive film numbers to particularly very lightweight jibs can alter the flow of the sail. More than two numbers can make scoring confusing, and the standard four-figure- registration number is often not sufficiently legible and, if only the last two digits are called, can mean duplication in any one race. Then, jib numbers are likely to be altered at different regattas, and cutting out (or buying) adhesive A logical answer might be to double the size of normal registration numbers and ‘stack’ them in two pairs. If the registrar has ten black numbers correspondingly followed by ten red and ten green in the subsequent hundreds, and tells the skipper the colour when he _ issues the registration, duplication in new registrations would be 300 apart. Thus, taking a totally random example 3732 would be black, 3832 red and 3932 green. The scorer would work only on the number 32 and if he knew there was duplication would note B, Ror G. The chances of confusion should be reduced to negligible proportions, the skippers wouldn‘t have to worry about changing numbers, and the last two digits would be easily read — in fact, 4Y,in. high rather than 6in. would probably be large enough. The colour differentiation should be no problem if a fairly light green (or lightish blue, though B covers blue and black!) is used. Thinking further, this would obviously mean (using the example above) that for simplicity all numbers 3700 — 3799 would be black, 3800- 3899 red and the next 100 green. Would skippers object to coloured numbers? The knowledge of which colour is likely to be allocated might influence their choice of hull colour, but in general the advantage of not having to change numbers and being able to paint on apermanent racing number (paint is less likely to affect flow) would outweigh any aesthetic concern. Analternative would be to set the 1000 number next to the national identification and use the other figures as race numbers, as sketched in C, using 4),in. height for the group of three (in this country) and insisting on plain sans-serif numbers rather than computer-style or other for hard to read numbers. This avoids the needdon’t scorers d provide tiation, differen colour mind working on three figures rather than two. fittings, bowsprit andrudder. In those days Braine sailing in this size. It might be thought that the gear was normal and to get maximum directional class still has much of its potential untapped, but think of the comparative legibility. This is, of course another digression. Other points from the meeting include the reminder that Stability and steering power with a first the rule needs a Stand the page six feet away and see what you national meeting host clubs are required to send in statements of accounts and the beginning of a drive to attract individual members. Some investigation into insurance which might cover individual members is under way; this would primarily be a service to clubs and might perhaps show a saving over the separate third party policies held by many clubs. There are, apparently, some aeromodellers with an interest in yachts who have wanted to use 35MHz equipment for sailing; since the frequency was allocated for the exclusive use of aircraft, regatta organisers may not accept 35MHz entrants. Apropos of radio and the dialogue between the Home Office and power boat, yacht and car bodies, the Home Office has apparently confessed to a belief that the S.M.A.E. and the M.H.T.F. (Model Hobby Trade Federation) had been representing all modellers and is surprised that there are other national associations who feel that their views have not been heard.

The 1982 A.G.M. will be held in the Colson Room at the Central Council of Physical Recreation (C.C.P.R.) offices, Francis House, Francis Street, London SW1 on December 4th. It was generally agreed that the experiment of holding it in Manchester had proved a failure with the lowest attendance and the lowest number of clubs represented for many years. There was one new affiliation, Milton Keynes M.B.C., Sec. R. Littlhewood 7 The Crescent, Whittlebury, Towcester, Northants. An unofficial request for a long-arm stapler (for publicity material) was made by Graham Bantock, Exhibitions Secretary, should anyone have one spare! Formal recognition was accorded to the Mickey Finn class (the class secretary being present) and will be offered to the 575 class. One of the main results of recognition is that a club sailing either of these classes but not official M.Y.A. classes can become affiliated; it also means that major regattas for the classes can be included in the M.Y.A. list. There is, of course, a difference between recognition and adoption, recognition meaning that the M.Y.A. has no jurisdiction over class rules etc. which remain in the hands of the relevant class association. Other items discussed were inconclusive and will be reported when further progress has been made, or concerned matters which will be over by now, e.g. the Dinghy Exhibition. Perhaps the only other subject worth mentioning is the dissatisfaction over the 36R rule as amended at the short, fat and usually relatively plumb-sterned hull it became the practice to mount the rudder trunk flush with the transom, with the rudder overhung as in Fig. 2A. Ignoring the bowsprit, which is rarely seen on modern designs, the other exclusion is “‘fittings’’. This was intended to mean deck fittings such as sheet horses etc., which could stick up on inch or more above the highest point of the deck line. However, with the increasing use of vane steering gear and the long booms resulting from unrestricted sail areas, it became necessary to allow the axis of the main spindle of the vane gear to be outboard, in order to ensure clearance between the vane feather and the boom end; this is covered in S.R. and G.R.R. 29(b), which also states that any (other) part of the gear may overproject the hull. It is implicit that the vane spindle is allowed to be outboard, the outrigger carrying it is not subject to measurement, and herein lies the snag. such yachts. It is an ingenious interpretation of the rules and it cannot seriously affect the sailing of lateral area aft. It also makes the rudder more effective, with directional stability beneficial and results for nimbleness in both tacks. Moving the CLA aft means moving the mast (or sail C.E.) slightly further back with less bow — down forces when reaching or running. in performance and quite clearly hanging of the transom and requiring that the outrigger Carrying it is above water with the yacht at rest, was passed at the recent A.G.M., and this is a compromise which appears to accept the principle in order not to discourage the construc- tion of new yachts to the class. Also adopted was an amendment to the effect that acertificate can be refused if in the opinion of the measurer the arrangement sailing has length the effect of the yacht, us with the rule to remain legal during their lifetime. It the rule and the amendment thereto are some- that advantage for many years; there are one or clause is provided and the yachts what contradicting and could leave measures two 1930’s 36R boats which are still sailed in slightly confused. A re-write of this short rule, vane competitions and, up to a year or two ago, returning it to its original intention, may well be proved highly competitive. At present the class is the least numerous the 1930’s not without controversy — requires but has shown signs of an increase in the last two or three years with well supported entries in open point of the deck line must fit in a box of inside dimensions 36 x 9 x 11in.
