Hobby Engine Richardson Upgrade by jarvo Fleet Admiral!   Posted: 6 hours ago
Hi there NP. Where do you want to start, I have converted several Richardson / Southampton, tugs. The first thing is do you want independant motor control, not found that i made a deal of difference, I now fit 1 ESC for both motors. Sound, when sailing you can't hear it, you can't hear most sound systems more than a few yards out, can be fixed but heavy so be careful, Smoke, in reality, smoke shows that the engines or injectors need servicing, on the model, try a computer cooling fan, the small ones to blow the smoke up the funnels. Better radio system, YES, which one your choice, but by a 6 or more channel system. Battery, a 7.2v buggy type NmHi pack will fit under the stern hatch, (just) or in place of the smaller battery under the front hatch, weight is not a problem, just get the balance right. I have altered the control cabin on 2 of my models, moved forward to the edge of the lower cabin, removing the steps down to the deck, also repositioning the funnels into different locations, ! model further back and the other the funnels were cut down and fitted to the top of the air intake casings, with a firefighting gantry across the top of them. In short, TX / RX upgrade, ESC, single or twin, 3300mah Battery last for hours, anything else, up to you. Hope this gives you some ideas. PS when cutting the wiring keep the motor wires as long as possible, i cheated and fitted the battery leads with a Mini Tamiya / Standard Tamiya converter Regards Mark

Crash Tender Shaft Tube Poistion by neilmc Commander   Posted: 26 days ago
Thanks both Doug and Dave I do have a couple of different mounts which were purchased to try and get round my sticky motor which initially proved to the glue holding the shaft had failed causing vibration and the old diesel mount causing misalignment. I have just recently even purchased a plastic type mount like the one you have Doug😉 Should have removed the mount when you suggested it a year ago Dave but a little scared now I can start a fresh. Now thats done and new lease of life should see me busy at the weekend. Little concerned on the hungry and smelly motor but like the idea of a Lipo with Tamiya connector will have a look for those later. Was a little worried about drilling through but like the idea of dowel and sand paper nice and easy I think until I get bored and then probably resort to the drill lol. Thanks for all the advice and the confidence you guys give. Ill update my year old blog with progress over the next couple of weeks.😁😁

Nice one Cyril! 👍👍👍😉 That's what I meant earlier with the Tamiya tape, great lines. 😎

Marking the waterline. by RNinMunich Fleet Admiral!   Posted: 2 months ago
Great idea 👍👍👍 I have one in the cupboard that's almost never been used, now it will be, first customer: Sea Scout 'Jessica'. Doug 😎 PS: A word to the wise regarding masking tape! A few years ago I discovered Tamiya tape (from the plastic magic scene!) It comes in various widths is very flexible and so copes with complex curves with ease and gives a superb clean line, without the slight 'stepping effect' that using lots of short pieces to approximate curves does 🤔

No power by NickW Lieutenant   Posted: 3 months ago
Yes the battery(s) are all Tamiya connectors...yes I have a basic voltmeter kit...well it's called a digital multimeter and no havent a clue how to use it but thought i'd need one at some stage...battery is charging now so will leave it until this afternoon and pop in here for the next round...if it helps i'm quite happy to ring (mobile) so I can carry out the 'tests' in real time and explain fully what i'm doing....anyway thank you in anticipation - to you both :-)

No power by Dave M Fleet Admiral!   Posted: 3 months ago
Hi Nick I am fairly certain your problems are mainly battery related. Do you use the Tamiya (white plug and socket) type battery connector? If so these can make a bad contact which then causes all kinds of unusual problems. We did get a good connection with the ESC working correctly. Subsequently the same set up had no power. This could be a flat battery or a bad connector not making contact. If you push and pull the connector and the set comes to life you have found the problem. Charging the flat battery should get you up and running again. Getting late now so perhaps we can have another attempt tomorrow Cheers dave

The Anchor. by robbob Fleet Admiral!   Posted: 4 months ago
I had previously assembled and primed the anchor, having added a little additional detail to the white metal castings, as described in a previous blog update. I subsequently added some plasticard pieces to the arm of the anchor to thicken it slightly so that I could fit a small brass shackle as a finishing detail. The final paint finish is Tamiya gunmetal metallic to match some other deck fittings. The anchor is held in place on the foredeck by a small double sided adhesive foam pad beneath the anchor base and the mounting pad it sits on. The base and arm is also retained on two other mounting pads buy couple of ‘staples’ that were formed by heating and bending some thin Plasticard rod into shape and they are just a push fit into some holes drilled into the mounting pads. The fixings are quite secure but as with many other items of deck furniture it can be easily removed for maintenance or repair. Sorry this is not a particularly exciting or interesting post but the next will be the suction hoses and fittings which were quite a challenge and will hopefully be a great deal less boring 😜

Shelduck by RNinMunich Fleet Admiral!   Posted: 4 months ago
PS: I noticed that the waterline (transition yellow to red) follows the wave line! Small tip: to accurately set the true waterline and keep it straight set the hull up on the building board dead level and vertical according to the plan. Use spirit level to check port / starboard for horizontal! (I.e. athwartships in marine jargon!) Make a small right angled jig to hold a soft lead pencil (or simply use a small try square). Attach the pencil to the jig / try square at the waterline height from keel according to plan. Then just trundle round the hull marking the WL with the pencil point. Tip 2: use narrow (ca 10mm) Tamiya masking tape (from the plastic magic department) to mask off the line itself. The rest can be masked as usual with cheapo decorator's masking tape and newspaper. Spray away to your heart's content. The Tamiya tape gives a wonderful clean line with no paint creep. Please don't be offended, nobody's perfect and I'm still in awe of your woodwork! 👍 cheers Doug 😎

MFA Torpedo 850 motor by Dave M Fleet Admiral!   Posted: 5 months ago
Hi camyaj I have used similar and they do work well and I agree they can handle high currents. I do have one reservation as the web link show Tamiya connectors to the battery and I believe these are rated at 15 amp when new. The Tamiya site has a discussion on connectors https://www. style='background-color:yellow;'>tamiyaclub.com/forum/index.php?/topic/56075-tamiya-connectors/ I replaced my connectors with Deans and have had no problems.

Finishing by Westquay Captain   Posted: 5 months ago
That's why I counselled caution with anything over acrylic...including, as it happens, acrylic. HRG enamels take a very short time to dry. In fact so much so that they sell a decelerator to slow drying time to maintain a wet edge. Very important when you're painting a narrow boat by hand, although a lot of people then use Owatrol mixed in with the enamel. I sprayed HRG enamel, thinned with white spirit and I sprayed all the parts of a kit car with it. It dried the same afternoon and was handleable the next day with ease. Needless to say it glossed beautifully, being enamel. Spray cans can be OK, but are very expensive for what they re and NEVER use over acrylic as they will wrinkle. What goes in those cans ain't pure water based acrylic, trust me. For one thing, it stinks a fair bit. I've painted enough slot car bodies to know that and what Halfords mix for you is pure, stinks-of-peardrops cellulose, whatever they might tell you. None of them know a fraction of we old painty farts know! If you can afford them, I would recommend Zero paints. They're formulated to be airbrush ready, need no thinning and are to quote the man that makes them, "cellulose only different". I did a 3 foot model narrow boat for somebody and they went on beautifully out of my Paasche Model H single mix airbrush (all you need). In fact I have also used them from my spotting gun (cheap as chips and easy to clean, IF you have a compressor). Zeros mask well too. Problem is he won't post and wants a fortune for courier. I won't play that game when I just had 2 deliveries of epoxy resin through the post. I have recently used Tamiya spray cans that were given to me (yes I really AM that tight) and they are excellent, but then, they really are cellulose. I wish I could buy cellulose, but it allegedly isn't made these days...Hmmmm. Something ending in "...ocks" comes to mind. I'd honestly stick to enamels bought from a car paint suppliers. Their wet'n'dry is cheaper too. Always talk to the organ grinder himself, never his monkey, hence auto refinishers' suppliers. Martin

None by misterbee Chief Petty Officer   Posted: 5 months ago
[Score: 5/10] Single Propellor Geared - Comments: This is the next project.......I think it is an old Tamiya hull,....fitted with an "Haribo" single prop, scale copy of a Volvo 280 outdrive (Zed drive).......and I am seeking input on how to power it.

Deck fittings, portholes and a door knob ! by robbob Fleet Admiral!   Posted: 6 months ago
Now that the painting is finished I can start putting on some of the white metal deck fittings. I had previously cleaned these up with a file and wire wool and sprayed them all with etch primer, some were drilled to take threaded studs to fix them through the deck or as a reinforcement for epoxy glue fixing into the deck, and some pierced to take a short fixing pin. The chain pipe was drilled out to make it look more realistic. They were all brush painted with some Tamiya metallic acrylic paint, I chose ‘gun metal’ for this as I want to paint some other fittings and window frames with a metallic silver finish as a contrast. The portholes were painted with the same colour as the cabin sides and glazed with the perspex that was supplied with the kit, 'canopy glue' was used for this as I read that cyano glue would 'mist' the plastic. Another small detail I thought to add was a brass knob for the cabin door, this was hand turned from some brass rod and drilled out to take a 2mm threaded stud for fixing through the door. A nice little finishing detail I think, and I'm quite enjoying working with brass 😁

Spraying the hull black. by robbob Fleet Admiral!   Posted: 8 months ago
Now that the red oxide has dried and hardened it’s time to mask it off in preparation of spraying the upper hull black. First I had to very carefully flat back the ridge in the red oxide paint left by the edge of the masking tape that might prevent the new masking tape laying flat. I chose two types of Tamiya tape, the first is the very thin and flexible type to get the sharp edge and this was then overlaid with the wider flexible variety. Once this initial masking edge was established all round the hull and at deck level I could mask up the rest fully. As an experiment and to prevent any possible bleed through of solvents through regular newspaper onto my lovely red oxide anti-fouling I chose to mask with some ’Bacofoil’ which actually works very well for this purpose as it is quite strong and easily folded and formed to the hull shape. I didn’t use too much of this from the roll, and my wife never noticed it’s absence from the kitchen whilst I was nicking it …result ! The hull was thoroughly wiped over with a tack cloth and panel wipe to remove any traces of contaminants that could spoil the paint finish and then it went into the booth. The pre-warmed paint went on very easily but at one point I noticed a bit of blooming on the surface in a few places but much to my relief this soon disappeared. Even after only one coat the finish looked very smooth and glossy. I left this first coat for a day or two to fully harden before wet flatting it down with an 800 grade abrasive. The second and third coats were applied in the same way, each left to harden for a day or more before flatting with a yet finer grades wet & dry paper. With the final coat on the finish greatly exceeded my expectations 😎 The masking tape and foil was very carefully removed to reveal a very sharp line where black meets red although this will be covered with the white ‘Trimline’ tape I bought from SHG Model Supplies at the Bristol model show in the summer. After a further couple of days drying and hardening I gave the black paint a bit of a polish with some Halfords cutting/polishing compound. I’m extremely pleased with this finish and at the same time frightened to death that I’ll ruin it in some way with a clumsy knock or in the lettering and lacquering stages 😓 …

Perkasa stabiliser by drspock Petty Officer   Posted: 9 months ago
Very little has been said anywhere about the stern stabiliser fitted to these boats. The precedent kit/drawing does not even show one,although it must be essential to several tons of boat at 50 knots! The tamiya kit shows it,but that kit does seem somewhat clinical. A chap "simon" on utube shows a comprehensive set of views of his model,which is the best I have ever seen,including what appears to be an actual photo of a real stabiliser!

Motor cutting out. by Dave M Fleet Admiral!   Posted: 11 months ago
Hi Steve What radio gear are you using? If it's not 2.4 is the aerial above the deck? Is the motor suppressed? Are your heavy current wires remote from any receiver and servo wires? Your symptoms sound more like radio interference than battery power problems. The advice given so far should help you solve faulty wiring and batteries. You do need good connections between the battery and ESC and motor. Electrics deteriorate over time and I have found the Tamiya type connectors to be unreliable at high current. I used to squeeze the female socket together and clean the male plug with fine sandpaper. Another common problem with older equipment can be corrosion in any of the black wire connections. I recently repaired a 7.2v NiMh that gave correct voltages but failed under load. The problem was corrosion inside the black wire where it had been repeatably bent when being fitted in a boat. I traced it to a thinning of the wire near the battery. Pulling on the wire resulted in the copper parting where it was rotten. There should be little or no give in good wiring. Replacing the wire restored the battery to full working order. Good hunting and I hope you find a solution. Dave
