The sketch- shows a typical installation in an electric powered 20 in. launch, using two No. 800 batteries for the main motor and 3 U 11 cells for the clockwork actuator, which is a clockwork escapement with the addition of a contact breaker to give stop (or half speed) in one of the neutral positions. This contact breaker could be a contact maker used to switch another escapement in. Several operations can. in fact, be introduced by such additions, but the limiting factor is usually the memory of the operator or the number of turns possible on the clockwork motor. Electric escapements (or actuators) are available, which do the same job. Care must be taken in selecting equipment, however, since some electric actuators will not work from—or will damage— all-transistor relayless receivers.

Transmitter should never need tuning once it has been tested at the factory and the average commercial receiver should be scry simple to tune, with a wide band. That is to say, there should be a wide (1-2 turns) tolerance on the ferrite tuning coil slug: through which the Rx should have the necessary current rise to operate the relay or. if no relay, the escapement. But we will deal with this later. Secondly, one needs a robust, smoothly with a 1.5 or 2.5 c.c. motor. This is large functioning, rubber-driven escapement. enough for R/C installation and not Single This should operate on 3-4J volts. excessively expensive to construct. Thirdly, one needs a model.

T here was a time when it was an embarrassment to recommend a reliable set of R/C equipment for the beginner, because there was no such thing. Radio was not only ultra-sensitive to tune, it rendered the operator super-sensitive. Nowadays, however, there arc many reliable sets on the market and unerring radio is the rule rather than the exception. Any expert will tell you that he started with single channel—this is the only way, so let us list the things required for that pencefe first R/C flight. tope wires in pioc* 103 “Carrier wave” sets have in addition a Repeal the process at a distance of 100 ft. shocking, isn't it?

In many cases the same servo can operate as either type, simply by change or con­ nection, The main field of application of type (iii) servos is where a limited number of control channels is available and sequence switching on one channel can provide additional services on that one channel. It should be noted that a single-channel actuator (servo or escapement) can also be operated by any single channel of a multi-channel receiver. This would appear to have distinct possibilities for multiple control operation via compound actuators using a minimum of channels—and thus minimum cost of equipment. Whilst this is preferable to the use of 'Cascaded' escapements with single-channel signal­ ling and does overcome some of the 'time delay' trouble associated with this system, it is not generally satisfactory. Certainly it is inferior to true multi­ off one channel only instead of two (as another particularly useful control for channel operation in practice and a true would be normal practice with a progres­ flying smooth manoeuvres and for main­ multi system, even with limited control sive multi-servo). taining smooth inverted flight.

The first and simplest of the two is the hard chine hull, where definite “comers” exist between the sides and bottom panels; in such a boat the frames or shadows arc shaped and fitted or stem end, is usually a fiat plate built sides and bottom panels are virtually flat to a jig which, in power boats especially, in as a bulkhead.

After gluemg the planks c e n t r e p l a n k s together, the outside is carved to its finished contours, using templates traced trom the drawing, before completing the internal hollowing. Ribs, bulkheads, and other interior details are added after the hull shell is completely finished. An alternative system becoming popular is “bread-and-buttering on the buttock lines”, which entails the use of vertical planks. The most common material for bread- and-butter construction is obcche, which is available at most timber yards and This is an expensive and wasteful means, model shops. Sugar pine, yellow pine, apart from the difficulty of obtaining good mahogany, and red cedar are also excellent quality material in sufficiently large sizes, and as a result “bread-and-butter” build­ BREADS BUTTER CONSTRUCTION ing is employed. In this system the “bread” is the timber and the “butter” CUT TO WATERUNES the glue used to bond the planks together. It has the advantage of being less wasteful and of rendering hollowing much easier. The hull profile and cross-section are first divided off on the plan into slices of the thickness of the planks available, and the top line of each division is used to mark off the outline for each slice on the timber—there is after all, little point in making a low “slice” the same size as the top one when it will have to be carved down anyway. Inside the outline a second shape is drawn and this shape is also sawn out and removed, thus considerably w T O P PLANKS 147 timbers for this job, though more difficult out, usually suiting with the garboard Note that it is only necessary to trace a to obtain. strakes (next to the keel).

No one interested in models of any sort can fail to be absorbed by its pages, which regularly detail the latest developments in boats and cars, as well as home-made tools and tips and gadgets for improving one's workshop or tool-kit. W ith "MODEL CARS" now incorporated in its title, the magazine devotes considerable space to electric model car racing that modern rival to model railways that it introduced and encouraged to its present high pitch of de­ velopment. Its coverage of model boats and yachts is unequalled, and its fine range of designs are to be seen on every model boating water amongst the winners.
