    Martin Westquay's Piper Cub ;-)
    Hi Martin - the OS10 will definitely be Super Cub rated - bags of power there - just don't overprop. Interestingly enough I have a water cooled head for an OS - not sure if its for a 10 or 20 - looks like a 10. Also has what looks like a back plate with two water intake fittings and all the bolts etc. Both components obviously original parts . Never found either a motor or taker for it . Price was R9.52 in 1982 (now roughly 50p !!!) Wot no steering wheel - we had those in solid wood - piece of pipe, cable ,two
    pulleys
    and a pair of eyebolts. Shows you us colonials were much more civilised - although the local soap box derby was run by the members of SOE (Sons of England society)

    Hi Rooky, Bit late getting back to you on this - bin kinda busyπŸ€” I hear where you're coming from (as our colonial brothers might say. Sorry Ed πŸ˜‰) Back then there wern't no Action Electronics / Component Shop so I just did what seemed logical! Worst (and smelly😝) part was making the circuit board. No PC, CAD or even photo-reactive circuit board back then. Yep, I know the Servomorph. I've bought one to experiment with on a Plastic Magic project. To drive the gun turrets on a 1/350 King George V battleship, where there ain't enough room (never mind weight margin) to mess about with cogs and
    pulleys
    . I'm thinking two micro servos, Y lead, or even independent A+B and X+Y turrets. My German Turnigy re-brand has two pots that I can assign to these! Many thanks to Colin-H for sending me the KGV kit in a wonderful package of 'stuff' as recompense for renovating and converting his Taycol Supermarine motor. Was like Christmas all over again 😊 Cheers, Doug 😎

    Steering Mechanism
    I thought of a few ideas on how to make the rudder servo controlled. However I thought i would stick to using the chain drive. You can see from the pics I manufactured a square tube with a slot in the top. From wood made a block that would slide freely inside the tube. I anchored the chain to either side of the block using ring nails. A drive pin was put through the slot into the block. The servo and drive mechanism fitted onto a base plate which fits into the hull. Four
    pulleys
    were fitted to deck and plastic straws used as guides. Effectively this works like the real thing.

Some of them are a bit "knife and fork" but there are some useful ones out there and there is lots of helpful information too.

    Emerald - ''Round the Word'' ocean racing yacht.
    Main Sheet Modification: Yachts of this nature, would be fitted with a Traveller, which would be used to help shape the Main Sail. Also, the route of the main sheet, has a lot of twists and turns to get out of the cabin and up to the Boom. Plus, it has to pass through the tube and bend at its edge. The starting point of the control would be from the cockpit, especially if it is a Single Handed yacht. The ideal place for the traveller, would be on the roof of the cabin. To keep physical disruption to a minimum, I decided to use the original boom running gear
    pulleys
    . The termination of the MainSheet would now be at the traveller on the cabin. 1. The cleat was removed from the cockpit, and the eye bolt was replaced by an S hook, screwed to the cockpit deck( see picture 1). 2. A hole was drilled in the cockpit, adjacent to the cabin hatch, and in a direct line with the main Sheet control system. This will allow the main Sheet to pass directly from the cleat. Through the pulley assembly (withought going round the pulley), and straight aft to the cockpit. 3. A brass tube was glued into the hole, flush with the cockpit surface and extending inside, towards the mainsheet control system (see pictures 1 and 2). 4. The Traveller was formed from a length of brass rod, (approx 300mm long), formed to the same curve as the cabin roof. Slide the pulley onto the rod so that it runs freely. Make a 90 degree bend at each end, the length of the traveller apart. These 2 legs will pass down into the cabin roof, leaving about 10 mm for the pulley to run from end to end. Plus about 10mm at each end of the rod, which will be bent up against the inside of the roof and glued. (see picture 3 & 4). 5. Mark the cabin roof where the traveller is to be mounted. I chose to mount the traveller directly under the boom pulley. I have made a revised sketch which is taken from the original plans for guidance. See picture 5. Note: make sure the pulley is mounted on the rod between the two bends. 6. Drill the holes in the cabin, pass the ends of the rod through the holes. I put a 10mm piece of wood under the traveller rod, next to the hole. This allows you to hold it securely, while you bend the rod out, on the inside of the cabin. Apply plent of glue or resin to secure it. Do the same at the other end of the rod, and leave to set. With the cockpit removed, and the mainsheet control system in place, take the free end of the main sheet and pass it through the new hole in the cockpit. The cockpit can be secured by the 4 locking
    pulleys
    . Now pass the mainsheet through the S hook and up to the boom. Adjust the S hook to suitable angle. When the yacht is rigged, the mainsheet is passed up to the end of the boom pulley, along the boom, over the pulley and down to the traveller pulley. With the tx/ex active, pull the mainsheet right in, and the trim set right out (this allows for final tightening).Secure the mainsheet to the eye of the pulley, ( I use a figure of 8 knot ). Now adjust the trim on the joystick to pull the main Sail tight. Finally, run the servo right out, and back in a few times, to make sure it works properly. Move the boat round so the wind cones from a different angle, and watch the traveller as the sail is pulled in and out. Now you are ready to sail. May your wake be long and straight. Ray 😎

All switched via a home brew decoder / switch board and 5V relays! Alles klar? πŸ˜‰ Re the DX5e; if I were you I'd let a (supposedly?) Spektum trained guy look at it first. With luck he'll have a service manual or at least a circuit diagram, which I don't πŸ€” and should know the binding procedure backwards. I could only do some rudimentary tests without the circuit diagram, and make some educated guesses. I could at least try binding it with a variety of Rxs, including my Spektrun RXs which all work faultlessly with my DX6. Up to you, will PM my address anyway. I could at least check, with a simple RF meter, if the damn thing is transmitting at all!

Wassat? 50 years on I got all threeπŸ˜‰ I like Lupins too, preferably the blue and purple ones. BTW, for your steering guy's arms you don't need a separate RC function or channel! You just need a coupling from the rudder control to turn a pulley and cord which turns a suitably scaled pulley attached to the wheel axis. The arms are fixed to the wheel and go with it! Dead simple (to write anyway😁) and no lecktrickery! 😊 OR you could just put one of his hands on the wheel and the other on the throttle. Then use a 'Y' cable to split the ESC cable into two. Connect the second output to a servo which moves the throttle lever via a push-me-pull-you-rod,
    pulleys
    and cord or gears or whatever. Sure you can figure out the mechanics better than I. Whatever, have fun and don't electrocute yourself, keep your socks dryπŸ˜‰ Cheers, Doug 😎

    Steep angled rudder shafts
    Ron, there is nowhere near enough space for that and also the twisted arms would still move through a strange path. I have snakes, but they don't seem to work as well as the man suggested. So, I've ordered a universal joint in steel which fits a 4mm shaft. I will take a short bit of 4mm out of the top on which will be the arm I've made, but that will need a bearing (just thought of that as I typed) otherwise it will flop about all over the place. Damn! More space I haven't got. Looks like the pulley idea might be the only way of working it, but getting access to those
    pulleys
    would be very awkward. I have very little space back there. We're in the lazarette and that was bend double territory on the real boat. The only other way would be to actuate the tiller on deck, once again with
    pulleys
    . I'm making the tiller currently. I may have to look into a deck operated system, with the line coming out of the middle of the deck and then via a pulley on either bulwark. Cheers, Martin

    HMS HOOD by Trumpeter
    Even tastier with the Frankfurters, and Colemans Mustard I trustπŸ˜œπŸ˜‹ Steve: I found a cheap way to mechanise the two aft turrets of my H class destroyer Hotspur, using one servo with a pulley, a couple of smaller
    pulleys
    on the turrets, about 2:1 ratio to give at least 180Β° rotation at the turrets, and a spring loaded nylon cord around the
    pulleys
    . I'll see if I can dismantle her over the weekend to make some pics. I plan to try something similar with my 1:350 Hood, also Trumpeter and also excellent detailing. Another way is to use one micro servo per turret, connected with Y cables if you want a synchronised Broadside; A+B and X+Y turret. Then use the servo travel adjustment at the TX to maximise the rotation. You can then move all four on one channel or two channels for 'Independent Firing" fore and aft. I will use the two pots at the top of the Turnigy i6 TX for this. On Hotspur I used the left stick left/right. I plan to do this in my Graf Spee, Belfast, Hood and Bismarck. Maybe also the ack ack turrets on Ark Royal!? Will knock up some test jigs sometime πŸ€“ Cheers Doug 😎

    M.V. TEAKWOOD
    The only remaining area requiring significant rework was the bow. Decided now to concentrate on getting the shape and dimensions correct. Made a template from a steel wire coat hangar, shaped to follow the Teakwood bow profile. Cut a mating recess in the upper bow and bulwark, fitted the template into it using CA glue. Once fitted and relatively rigid, cut a piece of styrene to fit into the space between the hull and the template. Epoxied the styrene into place at both the template and to original Velarde hull bow profile. This gave a nice looking bow from the side elevation, one that is also strong. Unfortunately, when viewed from the underside, the usual nice smooth water entry is not apparent. Had two ideas to attempt to blend the bow into the hull sides properly. The first was to cover this transition area with thin styrene and then feather it into the bow and the hull. The second was to use the modelers secret weapon, wood filler and do the same. After either approach planned to cover the whole area in thin glass-fibre cloth and sand down until smooth. Mocked up the styrene installation and decided to abandon the idea. The styrene makes the bow transition bulky, it also became quite clumsy around the upper area. Thought would try the wood filler approach instead. Shaped the rough filler with sand paper, it worked out relatively easily as it required little rubbing down. The modification worked out well and the bow looks satisfactory from both the side and underside. Decided also to replace the pulley drive arrangement with a toothed belt system. Have never tried this before and, as a friend of mine had a selection of belts and
    pulleys
    , thought would be useful experience to try it. One question perhaps somebody can help me with – what colour was the deck on this vessel? All my pictures showing the deck are in black and white!

Choose ratio of diameter pulley 1 to 2 according to the space available and final rotation rate (RPM) you want. Strong rubber band to connect the two
    pulleys

    Hi chugalone100 It would appear you have already worked out that some sort of pulley may be an option. Angled small gears may also work but there may not be the space available and you would probably need to make your own. I did buy from http://www.gizmoszone.com/ some very small (6mm) planetary geared motors that run on 3volts and are certainly suitable for your purpose via a pulley system. Using 1.5 volts gave a very realistic speed. Using one of these motors should allow you to use two small
    pulleys
    on the mast, where I suspect space will be limited. I would make sure you will always have access to the
    pulleys
    and belts as they will almost certainly need servicing over time. Hope this helps and please post details of the setup. Dave

    Sailing a straight line
    I appreciate all the good ideas and suggestions. I'm going to work through the list in an order which I think will be easiest and/or most effective. Starting off with increasing the rudder size by mechanically attaching something grossly oversize. if that works, I'll reduce the size step by step to find out what's the minimum size that makes sense. The rudders at present are oversize compared to the plan of the original. One of my early fixes attempted was to attach a 1" deep brass plate about 20" long under the bottom centreline of the hull as an external keel. I considered that would make a big improvement, but it made no difference. Steering control has a servo rotating a toothed pulley. The toothed drive belt goes around it and the two rudder
    pulleys
    . The toothed belt ensures the rudders move and stay synchronized. Roy

    Sailing a straight line
    It's certainly not a silly thought, but it would be major rework. So if that were to be the only cure, I'd have to live with the present behaviour. The screws and the rudders have been moved forward of their correct scale position to place the rudder posts inside the walls of the passenger compartment. I considered it the least offensive compromise to give access to the rudder posts. Moving the rudder posts outboard to the screw centrelines would mean major rework to the walls and deck of the superstructure, as well as the hull. Even with the rudder posts in their adjusted position, they are close to the walls and there was not enough room to swing a rudder arm. Rudder control is arranged using toothed belts and
    pulleys
    on the rudder posts.

Centre spot for the 1mm holes, place packing in the grove so it doesn't squash. The problem is holding, (could have done it in 4 jaw) but solved as the photo. Not many chucks will hold a 1mm drill, so I have glued it in to a brass tube. Twist thin wire through the holes & form a hook one end & eye the other.

    MFA used to do nice Olympus 2:1 toothed belt drives, but no longer. I have a set in a Rother class, nice engine Sound. SHG models sell the belts and
    pulleys
    , had thought of those. Also there was one on direct drive for sale on here, I asked what the motors were and got no reply. if I get it wrong I can reduce the speeds on my Spectrum transmitter to compensate.

    robbe dusseldorf fire boat Wanted
    The fitting kit for the dusseldorf consists mainly of
    pulleys
    , thread, tension springs and other bits and pieces to operate the monitors. Generally the forward monitor is operated seperately by two servos - one for rotation and the other for elevation. The rear two monitors on the cabin are arranged in the kit form to be operated in tandem by a further two servos. it then requires a 6 volt pump bought seperately or 12 if you use 12 volt electrics to feed all three units. I do have a Dusseldorf but have no intention of selling at present. You can fit quite a lot such as all lighting operating as in full size boat, radar scanner, scanning searchlight, towhook, dinghy crane, etc.,etc. Very unlikely that you would be able to find a fittings kit these days but if you can obtain a set of the plans there is sufficient detail from which to work out the servo layouts and pulley sizes required.

    Focus
    I have a Dragon Force 65 which is similar, but uses
    pulleys
    on the deck whereas I believe the Focus uses a winch below decks with fore and aft connections. Can't find an on line manual, but one appears to be supplied with the kit. I did find a YouTube video https://www.youtube.com/watch?v=XyXCHtHOk3Q which may be of some help. This shows a servo winch with an enclosed drum with connections for fore and aft sheets. Have seen them in use at my local club and they appear to work but can sometimes jam if the sheets are not kept taught. This is a popular model and hopefully another member will be able to supply a copy of the manual or pics of their set up. Dave

    Can anyone help me the Winch servo on the Joysway Focus. I have got a Focus hull with Rudder and sail servo fitted. What I do not have Is any Instructions as to how to connect the two sails to the Winch servo. I have had a look on line and
    pulleys
    are mentioned and continuous loop. Can anyone help.

    Joysway Focus Help needed.
    I have a Joysway Focus In bits. The problem I have Is that I do not know how to connect the two sails to the winch servo. I have done a little bit of research,
    pulleys
    and the loop system has come up a lot but I can't find any diagrams to put me on the right track. Can anyone help.

    HI Nasraf, Brass is mostly from Cornwall Model Boats with a few parts direct from RB (Poland) and the last remaining
    pulleys
    from Deans Marine. The 4 hand winches ate still being turned from brass stock and yet to be fitted. The gooseneck is hand-made from brass sheet and was about the most difficult thing as I do not have access to brazing equipment. I still need to make a kick strap as this gooseneck allows too much movement. Sails are made from a Hospital Cotton bed sheet. The mainsail is in 5 sections, each having a different curve top and bottom to attempt to get the correct billowing and twist. I was surprised at the reception issues and haven't yet ruled out a dodgy receiver (sourced on ebay!) I'll report back on the satellite receiver placement later in the week. We have a Night Sail on Wednesday so I can test my deck lights! Neil

    HI terijay How you choose to control your sails is down to personal choice plus you have already committed two controls, one for the rudder and one for the motor. if you have a four channel transmitter receiver this leaves two spare controls. I have tried multiple sail control on my Cariad but found little benefit and a great deal of concentration when sailing. Your model carries a fair amount of sail and whilst a sail lever system may cope a more effective solution would be a closed loop drum winch with the sails connected to the loop. This system has little chance of failure and provides plenty of pull to the sails even in a strong blow. I mount my winch servo on a board and run the cord from one drum round a pulley at one end of the board then to another pulley at the other end and back to the other drum. I find a piece of plastic electrical casing running between the
    pulleys
    acts as a good guide for a slider for attaching the sheet lines. Depending on the take off point you may need a return loop to keep both sails working the same way. You will only need about 6" of travel to allow your sails to extend to 45 deg. The other benefit is that you have only one sail control. I usually leave my fore sails to find their own position, using a rod or rope across the deck with the sail connected by a sliding loop and bowsie for adjustment. Good luck and please post details of your progress πŸ˜€

    Director class tug
    A paddle-propelled vessel is just an interesting subject, and these tugs were probably the final development of paddle propulsion. This will be a 'scratch' build, but the hull is from the Kingston Mouldings range, and many of the fittings will be from Mobile Marine Models. The superstructure and other scratch-built parts will be styrene, with the odd piece of brass. I have a windshield washer pump to supply one of the monitors, and plan to fit a sound system. Having purchased the hull, the first task was to assemble and test the drive train, and at the same time fit some frames to the hull. The main structure of the drive train is 0.080" styrene, with .125" plywood added under the base for stiffness. Each rotating train is double reduction using toothed belts and
    pulleys
    , powered by Electronize 365-14 motors. (Belt drive is not as compact as gears, but definitely quieter.) The servo operates a clutch which engages both paddles. The clutch is a gear on a swinging link which is pushed into (or out of) engagement with port and starboard drive trains. A test on the water with just the bare hull was succesful, although probably overpowered on 12V.

    Pulley Blocks
    I have been in the workshop taken some photos. Unfortunately something is blocking popups from my own computer very strange. So for now I will try to explain in words not my best subject. First I cut a strip of wood the thickness & with of one side of the block about 12inches long. Cut this in half for two 6 inch pieces. Next a strip the with of the block & touch thicker than the pulley to be used, about 4inches long. I make my own
    pulleys
    out of brass on the lathe. On very small blocks I may only use a nail (fixed) for a pulley. Cut the 4inch length into half inch pieces. Lay one of the 6inch pieces flat on the work surface glue a half inch on top at one end. Measure the diameter of the pulley plus the cord & allow a little more for clearance. Then glue another half inch piece on, continue until the end. Glue the other 6inch piece on top & weight down till set. Then shape as much of the end block as possible using a file & sandpaper. Fit the pulley before parting off, then start on the next.

    Cariad Bristol Pilot Cutter
    Started over a year ago, built from the Chris Brown fibreglass hull and plan. Got sidetracked with the Olympic build but completed this year. As well as the sails there is a small electric motor to help with recovery on calm days and to avoid the occasional water plant bank! There are two winches controlling the sails - an arm winch works the mainsail with a drum winch controlling the fore sails. I have tried to make the running and standing rigging as accurate as possible and made all the
    pulleys
    / deadeyes. The deck is planked with pine strips and mahogany veneer covers the rear cabin and cockpit. Masts are pine suitably dyed. I made the sails from the plans supplies but am not happy with the finished result and will remake in time. I have had several sails in most conditions and the model sails but not as well as I had hoped - not down to the design - probably my poor sails. There is 4.5Kg of lead in the hull and I remove this to assist with transport. Today was a very blustery day and I was lucky to make it back to shore as the boat was blown flat and shipped a lot of water. This entered via the rudder post and rear cockpit so a rethink is necessary. There is a solid keel so recasting the lead so it is all outside the boat and attached to the keel should bring the CoG much lower and Improve stability. I show the model "as is" on one of the quieter days on the lake but will show more details as I progress.

    (Pleasure Craft) Silver Mist
    Built from Vic Smeed's 1950's design but enlarged to represent 1:16 scale. Actually weighs 15lb and is a delight on the water- even though I say it myself! Will go quite ridiculously fast but looks best trickling along. In about 2014 I changed the MFA geared motor for a 500 motor with turned brass
    pulleys
    and O ring drive giving about 3:1 reduction. This is much quieter- the only sound the boat makes now is the whining from the esc. (Motor: 500 belt and pulley) (ESC: Mtroniks Viper 15) (10/10)

    PROP SPEED
    HI John Welcome to the site. Gregg's advice is spot on. 😊 At about 6' your model will look superb on the water but it needs to move at a scale speed. Good though the Decaperm is you already have a 550 motor and I have used this type of motor with a belt drive reduction unit that the model flyers used in their electric flight models. πŸ˜€ Unfortunately I don't know of any suppliers in the UK but possibly in the States you will find one. if you have any flyer friends or local clubs they may still have some discarded units, as they now prefer brushless motors such reducers are not required. πŸ˜‰ Another alternative is to make your own from small timing chain belts and geared
    pulleys
    . if you are not too concerned about a belt slipping and you have access to a lathe make your own
    pulleys
    and use a Hoover type belt. The flat version works best. As to speed, this will be in the hundreds of rpm and will depend on the pitch of your blades, the weight and shape of your model and depth below water. if the draught is not great there will be a tendency for the prop to cavitate so slow revs are essential when starting. I have nearly completed a 1:96 model of the RMS Olympic and that is 8' long. I have three high tork direct drive motors (777) driving similar size props. Ballast is 56Kg so your model weight will be similar. if the 550 proves insufficient you can always upgrade to a 700 or higher. πŸ˜€ Why not start a build blog on this site and share your experience with others. Good luck

    and belts from MFA/COMO Drills. 01304612132 or web www.mfacomodrills.com. I have used similar belts and
    pulleys
    on several of my models and they produce a really positive smooth drive. Good luck. Dave

    Replacement motor - suggestions?
    yep sound like the graupner unit. They always were noisy even from new. I have one somewhere but will never use it, if I can find it you are welcome to have it. Personally I would use a small 200/300 motor with a direct drive or possibly a home made reduction using
    pulleys
    and o rings. dave
