Hello: My Hobby Engine Richardson tugboat is a “premium” model with a factory-installed smoke system. Unfortunately, the instruction manual has no information whatsoever about the smoke system; not a single word. With a lot of generously given advice & help from Doug (RNinMunich) & other Model Boats members, I’m working on upgrading the tug’s lighting system & adding missing details. Unfortunately everything came to a halt last fall because of a fall & surgery to fix me up. So, for the time being I’m doing things that don’t require much finesse for fine work. I’m working on plans for future work as well as disassembled the tug’s deckhouse to access its circuit board. Once I had the deckhouse floor removed, I discovered that the smoke system isn’t a single unit. There’s a blower motor mounted in one location & the component that creates the smoke mounted in another spot. Tubing connects these two parts, then additional tubing exits the smoke generator unit & splits via a tee to each funnel. If anyone reading this post has a Richardson or Southampton “premium” model I would greatly appreciate information about the following: 1. There is a black rubber plug underneath the deckhouse. When the plug is removed I can see that it’s directly below the smoke generator. I noticed that the generator has white foam rubber inside. Is this where smoke fluid is to be placed? If not, then where? 2. Assuming there are different types of smoke fluid available, which one should be used in the tug? 3. How many drops of fluid should be placed in the system? I would appreciate any information about the Richardson or Southampton smoke system specifically & smoke systems in general. I’m not familiar with them at all & I need to learn. Thanks very much, Pete
Cabin detail part 5 speed control & compass The speed control has two main throttle controls presumably to operate the engines independently. The construction of this piece made it easy to allow each arm to operate independently but to ensure that the levers had some stiffness in the travel I incorporated a spring into the centre screwed shaft. I machined some detail into the body and a recess in each end face to accommodate a dial (AHEAD, ASTERN, STOP, SLOW etc). The circular body needed something to stand on so I made a cradle, which will support it when it is screwed to the framework. I left the whole unit in natural brass, lacquered it to stop any tarnishing, and mounted it with an 8BA screw to hold it in position. The compass again a simple turned piece of brass with a recess machined into the top face to accept a N,S,E,W compass dial. This item is simply glued in the recess on the console.
Ron Great to hear about this. I had a Kingfisher in 1972, powered by a DC Sabre 1.49 marine diesel. The engine was mounted just aft of the windscreen and it needed a a lot of ballast . With such a small engine and the additional weight the performance was mediocre. Is this kit in production again? If it is I might build one . Maybe this time I will fit a brushless running on lipos . This will give the model the performance it deserves. Boaty😁
Back to the build. Next milestone, to complete the superstructure and engine covers. The superstructure is essentially a cowl that supports the open bridge and serves as the air intake for the gas turbines. The engine covers fit into the rear of it. The superstructure is full of curves and will be interesting to make. Still trying to save weight, decided to make it out of glassfibre. Rather than first make a plug then a female mould and finally the cowl, wanted to try the technique of making a plug out of styrene foam sheet, then covering it in a glass fibre matt. Once the glass fibre is set, the foam is dissolved out using a solvent and the cowl remains – Inshallah! To ensure the foam did not react to the glass fibre resin, painted the finished cowl with enamel paint before sticking the matt down. See pictures. What a mess! The resin had crept under the paint and into the foam dissolving it. When the resin dried the plug had shrunk slightly and had the surface finish of a quarry. First thought was to hurl it and start again, this time in wood. On second thoughts, wondered if the plug could still be used. Decided to build it up with wood filler and from it make a female mould, as originally intended. The cowl would then be made from the mould. Built the damaged plug up and sanded it smooth. As the plug would be covered in fibreglass, the surface finish was not critical. Brushed a coat of fibreglass on the plug and, after drying filled any defects with glaze putty and sanded smooth. Once the finish and dimensions were satisfactory, applied a thicker coat of glass fibre to the plug. This was again smoothed down, waxed with carnauba polish and then covered in mould release. From it the cowl was made. Picture shows plug, mould and cowl placed side by each. The cowl requires reinforcement; the fittings and various mountings then adding before installing. A trial installation showed that it fitted properly the deck and was accurate. A lesson for the next time is to make the plug and mould much deeper than the finished item. That will allow any rough edges, on either the mould or the component, to be trimmed off leaving a smooth fibreglass edge.
Hello: I have a Hobby Engine “premium” 2.4GHz “Richardson” tug. This boat is identical mechanically to the “Southampton” tug. I’ve read many posts on the forum having to do with replacing the factory-installed motor/gearbox unit with two separate motors mounted side by side. Personally I’m happy with the factory drive setup; it’s quite powerful & it runs smoothly. The reduction gearing is a bit noisy, but my boat is new & will likely quiet down with use. I have two requests for those who have removed the factory drive unit & replaced it with separate motors: 1. If you’ve still got your factory drive unit & have taken it apart out of curiosity, if possible will you please post photos of the internal parts? I’m interested in seeing what’s inside the housing & how the gearing is set up. 2. Along the same vein, I’d like to acquire a spare factory drive to have on hand, just in case. If you have a complete, working drive unit that you’d consider offering for sale, please send a PM to me & let me know what you would want for a price. Thanks very much. Pete
Ah, now it's clean, it's easier to see. A Mills 1.3 Mk 2. A very good and much sought after engine. Much copied too! The water jacket is clearly an amateur jobbie. Not sure if Mills made a flywheel for marine use. Possibly for use on small tethered hydros and cars. The engine is worth more than all the rest of the boat put together! Nice job on the clean up. You could repair those mounting lugs with some of that aluminium solder I referred to recently. Cheers, Martin
OK, found one, 'discontinued product' 🤔 Seems Tower pro only make gas engines these days. https://hobbyking.com/en_us/towerpro-brushless-outrunner-240... Specs "TP 2408-21 The most widely used towerpro motor available today. the 2408-21T is often used in GWS (means Grand Wing System, USA apparently!) upgrades. Paired with just an 18A besc, this motor is an excellent and cheap way to upgrade small planes to brushless. An RD1047, RD9070 or 8040 size propeller are the best choice, with the RD9070 and 8040 giving the best thrust and amp draw balance. For 2-3 Li-Poly Cells (7.2-12.6V) 31 mm diameter x 62 mm length Maximum current: 13A Weight: 50.2 grams / 1.77 oz Comes with stick mount plastic frame Firewall mount capable Comes with two prop nuts and one washer 3mm shaft diameter 10mm x 10mm stick mount Kv: 1750 9 Stator Poles, 12 Magnets" So it's OK for a 3S LiPo, which will give about 19.400rpm OFF LOAD. Max current 13A ON LOAD. No way of finding the other little one without at least a hint🤔 Looks like an Outrunner plane motor as well. Suck it and see! Probably similar specs to the Tower motor. The two brushed ESCs should be good for your Taycols as none of them should take much more than 10A or so. Use 15A fuses, as I have already fitted to your converter boards.😉 Bon chance mon ami, Cheers, Doug 😎 Re GWS; https://www.google.com/search?q=GWS+models&client=firefox-b&... Pic is a typical GWS small plane, called 'Slow Stick'. If I had one I would name it 'Spindle-shanks' 😁
All parts of the engine made. It is set at the angle it will be installed in the boat. The regulator- reverser will probably be mounted remotely, but how knows. The gland nut drilled down a solid core in the cylinder for better alignment I hope. Have to hold the nut when drilling other wise it will undo.
Great job being done there Martin. My memories were of my Veron Viceroy in the 1960s with Taycol Asteroid sailing on New Brighton model boating lake rapidly going through 4.5 volt cycle lamp batteries wired up in series. I am made up to see a very original Crash Tender as the one I have now is a 1962 version I restored in 2014 from a wreck that was about to be binned which I bought for next to nothing from another person. in Ellesmere Port . On examination there was no evidence of the boat having an I.C engine but I did manage to find some mounting holes which appeared to match those of a Taycol Standard. This was a coincidence as Taycol did use photos of a 34 inch Crash Tender powered by the Standard in some of their advertisments including the leaflet that was supplied in the box with their range of motors. Boaty😊😊
Hi Bryan, If you want to do the SOE version she was most likely painted all matt black! The colour of skulduggery 😉 What ever you do, despite your good intentions to retain the 'old patina', judging by the photos you are in for a complete strip back and redo. Just as I have discovered with the PTB I bought. Thought it would just be a 'cosmetic job', flatten back and respray with Pacific green camouflage. Ho ho ho! Pics show what she currently looks like after cleaning off layers of enamel, and discovering that the prop shafts and rudders were misaligned and the chine strakes glued to the paint. 😡 Never mind an engine room fire when I tried to test the 'as bought' motor installation. 😭 Since those photos I have fitted new a new chine strake and started reinforcing the thin hull with glass fibre tissue. Next issue; set prop tubes properly and make an alu bracket to mount both the motors. Then set the rudder stocks correctly. Last thing I want is to dampen your enthusiasm, but that hull looks like it needs oodles of TLC. 🤔 Be aware of what's ahead of you and plan accordingly👍 Deck looks pretty neat, if unusual for a WW2 in service boat! As far as I can tell from the photos it's not just the cabin roof which is warped 😲 cabin and window frames will also need some attention by the looks of it. Before you run that motor I would strip it, clean all parts and check brushes and commutator for wear. See my Sea Scout blog 'Taycol Target motor' for a 'How to'. Should run well with a 3S LiPo, 11.1V. These boats weren't the fastest, 28 - 30 knots I believe. Which is why ST360 was reduced to more mundane duties after try outs by SOE. Don't forget some spark suppression!! Good luck, whatever you decide to do have fun doing it, Cheers Doug 😎
Started work on the engine. Drilled & turned the cylinders & end caps off centre. Simply done by packing one jaw of the chuck. The reason so I can mill down the port face to increase the width. (arrow & black mark) Also reducing the amount of metal, reducing start up condensation.
I have found that the No. 153 boat was possibly either a Brooke, of which one is for sale or a Maynard of Chiswick. I reckon the second as they made a 27 foot one which I reckon this is, interpolating the mens' height to the length of the boat. I will press on at that assumption and make a simple round bilge hull, as light as possible to use a small motor. The real one would have been a 75 HP ish engine, mounted just inside the raised foredeck. I'm sure there must be plans for the BPBCo. 37'- 6" Mk1 fire float somewhere. Cheers, Martin
Sketched out the engine, on a scrap of paper. the main frame 1"+ 1/8" two of joined by two 3/8" square. The square drilled through the centres (steam passages). Cylinders 5/8 hexagon, turned off centre to leave one flat. Also 1/8" left at each end to take six 10 BM studs for the end caps. The throttle - reverse mounted upright above to one side. Size over all 3"+ 3" The drawing shows most but questions welcome. I have altered this from previous engines I have made. Split the standard so I can increase the size of the bearings. This was a weak point before, didn't wear well.
I still have 2 SC 90's, 1 Sc 61, and an Irvine 120, all marine engines new in the boxes. I don't know what to do with them at the moment. Also a Zenoah 26cc all blinged up in purple with an electric start on it only been run in ready to go into an old 54" Hydrofibre Pipedream that has an outdrive mounted ready to take the Zenoah. Scratching my head as to what to do now.
