Upper & Lower Chines by rolfman2000 Fleet Admiral!   Posted: 7 days ago
Oh how this brings memories flooding back from 50 years ago, seeing the same construction as my original Veron Police launch (that's sat in the garage), going together. I bet the fit is a darned sight better than it was all those years ago, what with cad laser cut pieces and cad designs as well. I'm following this with even more interest, as I have permission of SWMBO to get the new bigger kit when it becomes available. Fingers crossed, not long now. Keep the installments coming Robbob. Best wishes, Dave W 😊

Proximity (Hall effect) sensor wiring by Haverlock Fleet Admiral!   Posted: 14 days ago
I do not know how much knowledge of electronics your friend has but I need to point out that a hall effect sensor is not like a relay. While they do act like a switch ( sort of) they need to be powered and have a hall effect voltage to switch. This would mean in the use intended there would be a current drain on the sensor and if the power supply ( battery?) voltage fell to far it would not function. The effect you want could be replaced by a reed relay cheap and simple to use. However reed relays can only pass low currents so would need to be cascaded with a higher rated relay before switching the main battery supply on and off. https://www.ebay.co.uk/itm/10-Pcs-2-5X14mm-3-Pin-4W-Glass-Re... these reed relays have both normally open and normally closed contacts and at a couple of quid for 10 worth buying so he can experiment.

HMS Cadiz by landie Chief Petty Officer   Posted: 15 days ago
[Score: 10/10] 48" HMS Cadiz Capable of 3mph and a runtime of 120mins Twin Propellors (3 Blade 25mm) Direct Drive Powered by LiPoly (14.8v) 7Amp/h Batteries - Comments: Scratch built other than a fibreglass hull, built by my father over about 5 years using a mix of balsa, plasticard, ply and wire. He never sailed it but when I inherited it I was determined to complete it ready for it's first "sea trials". I've completed the RC installation and adjusted the ballast and it's now had two successful outings at the local boating lake.

Smoke generator by landie Chief Petty Officer   Posted: 15 days ago
Mine is still in the "pile of bits on the bench" stage but when I figure out how to package it I'll post some pics. The model it's going into is HMS Cadiz, battle class destroyer which is around 1:96 scale so there's not a huge amount of space available, especially as the funnel is currently above the radio gear and batteries so I'll need to pipe the steam from the spare compartment I have nearer the bow.

Broads Light Class Cabin Cruisers by NorfolkBroads Chief Petty Officer   Posted: 16 days ago
Many thanks Richard indeed. Yes, decades of knowing these craft in real form and the designers and builders right back has hugely helped us of course gain such a first class reputation of precise detail. However, like all these things, such has not come without heartache, where in running up a one year purposeful trial as a manufacturing business for these, I simply failed in being far too much of a perfectionist, and this took too long in getting every kit out. Although we perfected the trial run on time for every customer, we realised it could not continue without mass stress for a sustained period of years, and so sadly had to pull the plug on the purposeful trial, much to the disappointment of many potential customers. Broke our hearts too, but then, what were we to do, our pride told us to pull back before running up a full production.

HMS BRAVE BORDERER by RNinMunich Fleet Admiral!   Posted: 25 days ago
Mornin' JB, Guess I'll have to remain 'agnostic' on this issue for now - I'm still to be convinced. This might explain a phenomenon I've noticed during testing of the Taycol Supermarine I've just renovated for Colin. More on that later in the 'Supermarine resurrection' blog. I'll do some experiments using my digital scope and see if I can trap and measure these elusive spikes for various wire lengths😉 Can't comment on the guy from Castle, don't know them, except to say that I found his comments a bit vague and without explanation. There are also contradictory posts on that link; some say before the ESC some after. Can't really see the point of putting the caps in front of the ESC, switching spikes SHOULD only appear on the output side I'll look at that on the scope, and after all a fuse to protect against fouled prop and jammed motor is standard fit between battery and ESC, or should be! So some wiring extension for that is essential. Also I would expect the battery to flatten any spikes that do appear at the ESC supply side. As you say the internals of several 'manufacturers' ESCs are often the same. Nothing new, branding and badge engineering has been going on for decades for all sorts of things and no RC kit manufacturer / distributor produces his own components. Important factors are; quality of his own assembly and where does he buy his components - originals or cheap copies? 28 ESCs! Wow 😲 and I thought I had a lot! As reported I have so far had good results with the Quicrun series, both brushed and brushless. Next one to test is their Dual Brushed version. Prior to going brushless I used a lot of Graupner ESCs - made in Korea., never managed to blow one of them either, not even the little micro and pico jobs. Thanks for raising this issue - I like a good debate and we can all learn something from it I hope👍 Plus; piquing my curiosity is always dangerous 😁 Greetings to Down Under from 'Up Over', cheers, 😎Doug PS Further thought just struck me (Ouch😡); if this is really a dramatic problem why have I never seen any warnings about it in any ESC instructions? Yes, I'm THAT guy who actually reads the instructions!!

Building my Carina sailboat from scratch by Hellmut1956 Sub-Lieutenant   Posted: 25 days ago
I have started the building from a plan I did purchase. So building from scratch is probably the right term. I am 61 years old and I have spent about a decade working on it. I use to build sailplanes as a kid and I did purchase my last sailplane shortly before leaving the university and there it is. Still, not even started working on it. In 2000 I lost my last job employed and reaching the age of 45 I was told I was already too old. So after a number of years, I did realize that I would not get hired for a job anymore and that reactivating my old hobby was a good thing to do. Being financially limited I decided to switch to a sailboat. Those do not crash as planes do and so building a sailboat from scratch looked to be a real option. I need to comment that I use to be a so-called Field Application Engineer for one of the large US semiconductor companies. Then, the career makes you develop into managerial positions. Disappointed by how salespeople worked and I shifted to sales when moving to another US semiconductor company. My active professional employed life did get me to be a Business Developer Director with one of the largest US telecommunication companies. Due to this history at a certain point of my project of building a sailboat from scratch started to have electronics and informatics becoming the dominant activity. Another topic that influenced about what I am doing on this project was due to now limited financial resources. So I decided to work on improving my workshop and to organize the many items I had been accumulating over the many years. It used to be easier for me to buy something I knew I had somewhere in my workshop. So this also influenced my activities on my workshop. Finally the heavyweight of electronics and informatic aspects of my project I started to build an electronics workbench. Sadly I do have a lot of health problems, 4 strokes, heart-stopping to beat due to side effects of medicine I was taking since I was 19 years old I got a pacemaker. Lately, I am slowed down due to being tired for many hours of the day and by suffering from a reduced concentration capability. As being positive, as having a well organized day and fascination to force that organ between my ears to work so that it can reorganize itself, I am happy working on the diverse subprojects. So the work for my project has become my focus and objective and not finishing the project.

ESSO CADILLAC by oldcodger Chief Petty Officer   Posted: 1 month ago
I’ve always wanted to build a WW11 oil tanker of the type my father skippered during the war. It’s named after a tanker he left to go on leave. The crew didn't want him to leave as he would take their luck. It lies off the west coast of Scotland, the captain, a friend of the family, going down with her. It's not the actual Cadillac as it was an older ship, artistic license!

Tarpon hardware help by steve-d Commander   Posted: 1 month ago
Pretty boat that. Probably know as much about motors as you do but, What may make a difference is what battery you intend to use, Style of boat does not make for rushing about the pond so a 12v lead acid battery would probably be in order in which case the 12v nominal motor would suit. If you plan to use Nicad 7.2v battery then the other motor is more suited. waits to be shot down or should that be scuttled. Steve

Bulwark Stays by RNinMunich Fleet Admiral!   Posted: 2 months ago
Evenin' Mike, Murmansk as well! Your Pa must have been through the mill! During my nefarious travels over the last few decades I ended up in Muscat, Oman a few times to discuss COMMS refits and upgrades for their fleet. In Muscat I stayed at the Marriott hotel which has a bar called 'The John Barry Bar'. Since I only knew John Barry from the James Bond theme I wondered why! The barkeep told me it referred to a liberty ship supposedly carrying bullion to Russia and sunk off the Oman coast in August 1944. In fact she was carrying silver coins to Saudi Arabia! They didn't have paper currency then so that was the only way for the allies to provide funds for services rendered. If I ever build a Liberty ship model - she will be it! Cheers, Doug 😎 PS Took several 'John Barry' beermats from the bar 😉

HMS Campbeltown 1941, 1/96 scale by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Steve, On my Manxman, a fast cruiser / minelayer, it was used to protect the deck where mines were dragged from the stores to the laying rails in the stern. Otherwise I've never seen extensive use of it on open decks. Mostly just in enclosed areas where there would be a lot of 'foot traffic'. In recent years (decades!?) I've seen blue, yellow and green versions inside the vessel, especially in the so called 'Citadel', a protected area which can be hermetically sealed against chemical or biological attack! 😲 The 'non slip' variants on the weather decks all seem to be paint / resin mixtures containing some sort of abrasive material. I don't think it is worth the effort you describe to depict corticene!! Cheers, Doug

Styrene Allergy? by Westquay Fleet Admiral!   Posted: 2 months ago
Certainly not melting and I'm pretty sure it was soft solder only as I know he had no knowledge of silver soldering. I use silver solder (hard soldering) all the time and have done for over 50 years, most of it with cadmium rich (still, I get it from ebay) and I have had no unpleasant reactions. OK, currently I have the shed door open as it's a very small shed, but I never used to in a 7x5. Before that the space was always bigger. Cadmium free modern silver solder is crap as it will not flow as well as Cadmium containing. Martin

Hobby King receiver clones by RNinMunich Fleet Admiral!   Posted: 2 months ago
Mornin' John, I've used 'Generic' crystals with my ancient Sanwa 35 Meg set with no problems. I do find tho that the 'FM' crystals seem to give better range than the 'AM' crystals. Check the specs of your TX whether it is AM or FM. Cheers; Doug 😎 DEACS!? My God, when did I last hear of them let alone see one😲 We used to use them in professional personal VHF/UHF radios (Police and the like) some 45 years ago. 400mAh was good stuff in those days! Threw my last examples out about 10 years ago, they had some interesting and quite artistic crystal growths though😉 Was just a brand name for NiCads.

Hobby King receiver clones by Westquay Fleet Admiral!   Posted: 3 months ago
Colin, I first entered the world of proportional RC with a set called a Mini-Hex, in 1971. I bought it from the model shop in the arcade in Exeter. It cost a bloody fortune! 2 Function, essentially a copy of the Kraft set, but made in Belvedere, Kent. I still have it and as far and I know it still works, except the old DEAC battery pack is defunct, of course. It even came with it's own metal cased charger. Green frequency only, can't be changed! Cheers, Martin

Darby One Design hydro... by Westquay Fleet Admiral!   Posted: 3 months ago
Dave , I made it. I found plans in a 1954 copy of the Motor Boat Annual I borrowed from the National Powerboat Museum at Pitsea, before the stupid bastards on the council threw it away in preference for mud huts for snotty nosed brats to go mad in. Only today I finally got some pictures from the Oulton Broad club with pics of the Darby boasts I hadn't seen, which show that the top cowling was always built a little higher than the plans show, so I shall be making some slight changes to the fixed portions. The photos show the fixed sections to be done with stringers and fabric, a la aeroplane fuselage. You can't buy decent older powerboats as kits or ready mades. Nobody gives a toss about speedboat models in this country, alas. Even though we had a very busy world of inboard race boats at one time. Now, all is boring outboards. The 1500 cc inboard classes gave us a lot of great racing just pre and post-War. Here are three in one race. "WHO'S DARBY?", Dawn, a Whippet class and Miss Windermere, another One design, like the Oulton Broad One design, all three are 1500 cc class boats. There wqere also boats of under 950cc and even a Singer Cadet class with a Singer Le Mans 1100 cc engine. The Singer Commodore had a 6 cylinder 1500, a gorgeous engine. Both Singers were designed by Percy See at Shoreham and had diagonal reverse clinker construction. I have plans if anyone is interested. Cheers, Martin
