Bending thin plywood by Westquay Fleet Admiral!   Posted: 1 day ago
When I typed that, the little thing on the left said Forum posts: 666, but it no longer does, oddly. People have this thing about the number. And I would say the doctors use the machine that most reliably runs the NHS programme they all use. They have updated the appointments system (with no obvious improvements), but the normal medical files aspect always seems to work very well and they are very good at reminders, etc. compared with my last surgery.

Taycol Supemarine Resurrection by RNinMunich Fleet Admiral!   Posted: 3 days ago
Hi Boaty, The Taycols have fascinated me as well, ever since I dug the Target out of the Sea Scout my Dad built in the early sixties. I blogged my renovation of that and the conversion to run with a modern RC system and presumably that, and the converter boards I built for Martin (Westquay), is what triggered Colin to ask me to have a look at his Supermarine. How could I resist!? 😉 The 'smell of something electrical' is the ozone gas caused by the prolific sparking of the Taycol metal to metal brush / commutator combination. The other source of Ozone is on the coast wherever there is a strong surf! I agree, a nostalgic smell, which unfortunately disappears when the converter board is attached to make it run with a standard brushed ESC. The diode bridge kills almost all the sparks. 'Almost' so the usual suppression capacitors are still recommended. 0.1µF across the brush terminals, 0.047µF from each terminal to the motor can, or frame in this case. Earth to prop shaft tube as well if possible. The motor may not disturb the on-board electronics of your own boat, if using 2.4Gig, but could still affect anyone nearby using 27 or 40Megs. The power density of spark transmitters (e.g. unsuppressed E-motors, peaks in the upper HF bands and diminishes to almost zilch in the UHF bands. I.e. approx 300 MHz upwards. Like me and other submariners for instance; 2.4Gig is useless for subs cos it don't go underwater. Cheers, Doug 😎 But here! BTW Boaty: where are the pics of your Avanti? Harbour posts without pics are pretty dead 🤔 Cheers, Doug 😎

Taycol Supemarine Resurrection by Colin H. Fleet Admiral!   Posted: 3 days ago
Wholeheartedly agree Boaty, my fleet is made up of vintage boats which I love reviving, most of them were donated to me over the last 4 years my wife and I both enjoy sailing our boats and trying to encourage younger folk to try it. I have no problem turning over control of my 50 plus year old boats to total beginners of any age, the youngest so far is my grandson who started on his 3rd birthday with a small rc boat I bought him. Now at 4 he's getting quite good and learning learning manoeuvring with my large tug Valiant which is just over 4ft and pushing 60yrs old. I have never been tired of those that are willing to learn and have a go. BTW The supermarine is mine and I am going to be installing it into my father's old sea commander built in 1957. Originally had a diesel, but the taycol is the ideal replacement. And with Doug doing the rebuild on it I will be able to use it with my modern rc system. Cheers Colin.

Exciters/transducers by pmdevlin Fleet Admiral!   Posted: 5 days ago
Im not on here that much, so a little late picking this up. Are you talking about TT25 transducers like the ones Mrrcsound sell/ I suppose they all work the same, I've used these a lot, in planes mostly, and experimented with boats, so can offer some hands on advice. Firstly, you don't cut any holes to let sound out, as this isn't how they work. Its all about the vibrations. The centre ring is epoxied (that's the best way, they have to be permanent, but with some teasing they can be removed it required, rather than cyno) to the surface, which obviously needs to be flat. The thinner the material, the more sound, but its marginal, as the thinner you go, the less bass, or deeper tones. With planes, the best material by far is the epo foam, so when mounting into a ply or balsa plane they work best going to foam, then the ply, and the same will apply for a boat. 2-3mm is generally the optimum thickness. Remember, the area is going to vibrate, so use an area that can do this, the sides of a hull are ideal. The back of the transducers get hot, so don't cover the back, the heat has to dissipate and once secure, make sure the unit can move in and out, its easy to drip glue in the wrong place and the whole thing gets stuck, it wont vibrate now, so won't do the job. Also, its worth epoxying the transducer to 2mm foam, epo that the ready to fly planes works best, its close density, the stuff that packs white goods is poor as its a more open density and falls apart. Once you have this, you can move it around by just holding it against the hull to see where the best sound is. All this is relevant to the Mrrcsound transducers, I use a number of his sound units, so cant really comment on what you are using as I cant find that info on this thread (did a man read!) Here are a couple of my models to give you an idea👍 https://www.youtube.com/watch?v=jXFvrkDl7ow&t=207s https://www.youtube.com/watch?v=_OITvPabFHY&t=165s so these are all Mrrcsound units, and both have two tt25 transducers either side ogf the hull and fuselage. With the Mrrcsound systems, you can use two tt25, if you want an additional two, then an aux amp is required hope that helps! Paul

Miss Maryland by Cozwhy Sub-Lieutenant   Posted: 6 days ago
Huson 24 RC sailboat wooden hull. I have a small fleet of these. They are extremely stable in high wind. Bought this one online in pretty good condition. Did a lot of smoothing on the epoxy coated hull. I use West Systems epoxy because it flows so well - like paint - and doesn’t stink. Finished the MD flag on the sails.

Where's Figtree gone!? by RNinMunich Fleet Admiral!   Posted: 7 days ago
Hi Ed, Make it a 12 foot Log Periodic then you can cover a wider frequency range and sharpen the beam and antenna gain at the same time😉😁 Moral; don't trade antenna jokes with a COMMS engineer 😁😁 Sorry Ed, couldn't resist that, but can appreciate your annoyance with the WiFi. I got so fed up with WLAN drop outs I simply bought a router with more ports and hardwired all my LAN gear. I've also separated my Internet and HD TV feeds on separate systems so that I can't lose everything if one system goes down - power cuts excepted😲 Haven't got around to rigging up an auto back-up diesel genny yet😉 Since then no snags - fingers tightly crossed! BTW: if the distributor in your block is a communal system have a moan to the house / facility management or whatever you call it over there. Also check around if your neighbours are having similar problems. Cheers, Doug 😎

BRAVE BORDERER by RHBaker Fleet Admiral!   Posted: 10 days ago
Been researching the squeal and stutter on other websites and conclude RFI is probably not the major contributor. Others attribute it to a mismatch in the ESC / motor timing, which seems more likely. Whatever caused it, resulted in the affected motor failing. Which came first, the failure causing squeal or squeal causing failure is open to conjecture. Much to my surprise the manufacturer has decided to replace the motor under warranty. In the meantime, the motors I had planned to use originally (2800kV Outrunners) came into stock, so purchased a couple. Until now have had to use the ESC default settings as did not have a programming card. This also arrived with the motors. Following advice from another contributor reprogrammed the motors with “softer” start and acceleration settings. Fitted and tried the new motors and settings. On the bench, the squeal and stutter have almost gone. The motors are also more tractable. As the brushless motors are now going to be used for high speed operation only, with slow on the centre brushed, thought could simplify the controls by putting the brushless ESCs on one control system using a “Y” lead. However, this introduced inconsistent and erratic motor responses. Reverted to the two previous separate controls, port and starboard. On the water the performance is fine, as is the reliability. The 2S battery gave almost half an hours operation. The bow lifts nicely with both 2 & 3 S Batteries; plenty of spray. Hopefully resembling a 50 knot vessel! Another adjustment is needed to the transom flaps to try to hold the bow down later as she accelerates. Feeling now to finally be making progress with this model. The squeal has not gone, nor has erratic motor operation. The squeal is high pitched screech, rather like treading on a budgie! When it happens, bringing the control back to neutral and advancing it again almost always overcomes it. The erratic operation happens also when starting and is rather like the motors are not getting a signal to react to the control. Again, returning through neutral briefly seems to correct it. The revised motors and ESCs have increased the weight to 6lbs for the hull including all running gear, excluding batteries and superstructure. Whilst still trying to control weight have concluded this figure is satisfactory as the performance certainly is.

Looking for Vosper Gunboat from Republic of Singapore Navy by RNinMunich Fleet Admiral!   Posted: 10 days ago
Mornin John, Yes, so far I haven't found an Islay malt I don't like. Jura was the first I ran across and their Superstition is very nice. Lagavulin was a recommendation from a secretary (!) at work a few years ago, and the group I worked for (Naval Communications Systems) gave me a decent supply when I retired last year 😊 The EDEKA chain here have a few larger 'up market' stores which carry a decent selection, including Jura and Lagavulin etc, at halfway reasonable prices. 😉 For more exotic varieties there is 'The Whisky Shop' in the centre of Munich. Spoilt for choice😋😋 'Through the teeth, round the gums, look out stomach, here it comes' 😁 All the best, Doug 😎

Tony O by RNinMunich Fleet Admiral!   Posted: 11 days ago
No Martin, I don't think so. Once again; it's not so much what you say but HOW you say it. If your chat with the 'only geezer' was in the same vein as your recent posts I can fully understand that the reaction was 'don't call us - we'll call you'. Patience is NOT an excuse for wasting time. It is an essential component of successful negotiation. During my career I was often involved in systems design and contract negotiations for COMMS systems for ships yet to be ordered and built. Many of such projects took 5 to 7 years or more to come to fruition. My perseverance and patience paid off. I was the one who signed the contracts! I often heard from the shipyards and/or navies involved that they were put off by the 'pushy' tactics used by my competitors with less patience. Tolerance is also not a weakness. Lack of it IS. Differing opinions are fine, just depends how they are expressed. Denigrating and insulting others who have differing interests as morons is not the 'fine English art' ! Re: Dumbphone control Apps; YOU don't necessarily need to know (a Luddite wouldn't want to or need to anyway!) but the parents of your grand kids SHOULD in this day and age. Tell 'em to look for Apps like 'Quiet Time'. This enables them to define times that the kids can access the web online via smartphone and when it is blocked. And no, the kids can't normally get around it. If they can; leave 'em alone to make their millions! Re: Woodies; Super duper. You have seen that I have put a tremendous amount of effort into renovating the Sea Scout that my Dad built in the early sixties. I enjoyed the process and learned a lot doing it. But I am not fixed on that particular line of model boat / model ship building. If that's your only thing - fine. But why berate those of us who take a wider view and also have an interest and find challenges in making shipboard functions work in miniature in all sorts of ships? "I really couldn't give a sh*t if I was the only person left in the world making woodies. I do it for me only these days in the absence of any clubs. But I don't have to pretend to like all the other stuff. In another place are people who not only do sail, but specifically model barge racing and good on 'em. I don't ask that they do all the other stuff" No, of course you don't have to pretend to like 'all the other stuff' but you also don't have to decry those that DO like the other stuff, as you often do the tug aficionados for instance. OK, I can understand an aversion to warships as such if someone is a died in the wool pacifist, but nevertheless some appreciation of the skills involved in producing such outstanding warship models as seen on this site is not out of order, or...? (Bye the bye; I've often noticed that 'pacifists' have a particularly aggressive way of expressing themselves!?) After 30 odd years here in Germany I'm out of touch with the ground roots in UK, but over here things don't look so black. There are thriving model boat clubs all over. W.r.t. 'exciting aspects'; there are clubs in Germany, Holland and France and Italy also I think who happily and skilfully re-enact sea battles and convoy battles. There is at least one club in South England that also does that I believe, in Southampton or Portsmouth? Don't get Channel 4 here (re Battle of Britain re-run you mentioned) but I do get DMAX, which shows a series called 'Die Modellbauer'. In this the crémé de la crémé of German model making is depicted and judged for the annual cup at the International Model Show here. It covers everything from fire trucks, excavators, boats and ships of all kinds, and aircraft of of all types including turbine jets. Criteria for the competition being: 1) Shall be externally identical to the original in every detail (down to the rivets!)l, 2) Shall be able to perform each and every function of the original. 3) 150 days to design, complete and demonstrate the model. The point being that with extremely few solo exceptions the models are almost always built by a father and son partnership. So, sorry if the situation is drastically different in UK but 'over here' it ain't so black as you paint. Maybe it's a question of the attitude of the parents? BTW: for a fantastic example of 'modelling on a mammoth scale' pop across to Hamburg and have a look at the 'Miniature Wonderland' in the old Hafen City. All 1/87 scale, the largest model railway layout in the world, but also all types of aircraft and ships in action as well. Also shown from time to time on various documentary TV channels. BTW2: don't worry about the brass bashing, I'll work it out for myself. Have fun with the Taycols. Cheers, Doug 😎

Sails logo and new booms by Cozwhy Sub-Lieutenant   Posted: 12 days ago
The sails need a little repair and Singers fabric glue really worked well. Still have fittings to add to main boom, but you get the idea. Thinking about how the plans rig the sheets. Will try it their way first, but looks like the servo is at a mechanical disadvantage. Plans say max wind is 10 mph! That’s way too low. Black booms are made from aluminum arrow with fittings made from brass sheet and copper wire. Reinforced keel to bulb connection with fiberglass cloth and West Systems epoxy.

Clyde Puffer by lesliebreame Admiral   Posted: 13 days ago
At Illfracombe pond last week . Have made an automatic feed water system for my coal fired Puffer and went to the pond to try it out. I think it needs bigger capacity pump as there was very little water in the boiler after 3/4 hour running. Gordons hydro is beating me up as usual !!! Les Breame

Launch ELAINE, by Colin H. Fleet Admiral!   Posted: 17 days ago
Well today the radio specialist guys checked out the reciever for me, apparently it would need a new capacitor, a 90 volt and a 2 volt supply. Not really possible in such a small boat. So I've decided to use it for my vintage displays. The boat itself will be renovated and fitted with an electric motor, possibly a 600 as I have a couple in the spares box. Still looking for a way to remove the kitchen nozzle system. The motors that operate it are working so hopefully should be controllable by modern rc gear. Might need Dougs help designing a system I can build. BTW the Hull and cabins and deck is constructed from 1/4 Inc ply. Bit heavy but good and solid except for some of the frames are very soft and crumbly. Will start a resurrection blog soon. Cheers Colin.

Schnnelleboot Battery by Kipper Sub-Lieutenant   Posted: 18 days ago
Not necessarily, it would depend on the amount of current your 3 motors would draw & the voltage + ah rating of the battery. For instance, my tug has 2 motors - 2 esc - 2 sla batteries, they make 2 separate systems, port & stb, so if I lose one side, I can still tug with the other. They would both run just on 1 battery if that's all I put in the boat, but using 2 batteries saves me having to use a lot of lead for ballast.

Launch ELAINE, by Colin H. Fleet Admiral!   Posted: 19 days ago
Picked this up from local antique shop, the shop owner said it was from a house clearance and made in the 1940's. It needs a lot of work to be done to bring it back to life, look at the photos and see if any of you can help, as I haven't seen any control system like it. I think the motor is a modified plane engine but the water jacket will have to be destroyed to find out. So any thoughts on the challenge ahead would be good to hear. Cheers Colin.
