Cracked Battery! by RNinMunich Fleet Admiral!   Posted: 1 day ago
Hi Ed, NOT 40 bucks each I hope😲 I use the Yaesu SLAs, not expensive and last for years as they are designed for use in long term applications, such as emergency lighting system, remote instrumentation systems etc. Cheers, Doug 😎

Weight Too Much! by figtree7nts Fleet Admiral!   Posted: 3 days ago
Captain's Log: After careful consideration. I have decided to use only one battery at a time! This being 6.5 lbs. is way too much weight. Her bow is too low to the waterline. She get's thrown off by the weight. So, one battery at a time will be used! Now, having lowered the volts. From 12 volts to 6 volts is a problem. See her main motor and smoker. Are 12 volts each! So, now I have to replace. The main motor and the smoker. To a 6 volt system! This is not so easy. If any of you are familiar. With Dumas and Harbor model products. You know this ain't cheap!😭 Luckily, I will be selling both parts. Together next month! As both parts are in new condition! I will then order a 6 volt main motor and Smoker! Oh, each battery will give me about 1.5 hours of run time! And that's not bad at all..... NOTE: I'm only losing $10.00 on the resale of her Motor and Smoker!

Park lakes by mturpin013 Fleet Admiral!   Posted: 3 days ago
You may remember I was having a long running discussion with Leeds city council about sailing on the two lakes at Roundhay Park and seemed to be getting knoware. Until a new councilor took up the challenge and it seems all systems could be "GO" I'm meeting him at the lake on Wednesday. Fingers crossed PS I'm not sure if any other members are in the Leeds area who may be interested in sailing at Roundhay Park, please contact me

Rx-tx confusion by DodgyGeezer Lieutenant   Posted: 7 days ago
"....Am I expecting too much to get a definitive answer from the inter web?...." If you ask a system which has 3.25 billion people connected to it, you are unlikely to get just one answer... 😤

Cabin detail part 3 (instrument panels) by mturpin013 Fleet Admiral!   Posted: 10 days ago
After the Christmas break its back to the cabin to finish some of the instrument detail. You may recall I detailed the cockpit with some ply constructions to represent the general layout; I also intend to detail the compass, throttle controls, steering wheel, panel lighting, and instrument panel. The instrument panel was copied and scaled from various drawing and pictures and I came up with a three-panel unit where panels 1 & 3 are identical as they are for the two-engine managements system the centre panel deals with electrical things. I intend to make the panel out of 1.5 mm aluminium cut to size on the guillotine I then attached this to a hardwood block with some strong double sided tape this will be more than strong enough to hold the piece for the drilling/light milling operation. I worked out the hole positions using an absolute datum (same as CNC work, if only I was still working) This does take some time using my rather old milling machine making sure any backlash is taken out during the 28 linear movements. I used various sizes of centre drills to produce the holes as they give not only accurate size but also perfectly round holes on thin material and the only ones that needed to be a particular size (6mm dial holes) the others are for switches and LEDs which can all be a 3 mm location hole. Each hole was drilled and then chamfered to simulate a bezel on the dials. Finally, I milled a shallow groove (2mm x 0.3 deep) to simulate the separate panels. I have copied a number of different marine dials from the internet and using PowerPoint I aligned in a complete group and then printed and laminated them, this will be placed behind the aluminium plate using double-sided tape. Having fixed the dials in place I drilled through the holes where LEDSs will fit. The LEDs will be shortened and polished so they are flat to the face; these are then stuck in place. Next, I made all the switches from brass bar with a fine brass pin glued across its face to simulate the lever. These were painted gloss black and the centre pin picked out in red, they were then glued into the 3 mm location hole. The black knobs/pull switches were turned out of black Perspex and polished; they were then glued into the location holes. The whole instrument panel is then pinned on to the wooden framework which has been left in natural wood finish (ply) as it looks like the original boat was just a varnished ply finish.

HMS Campbeltown 1941, 1/96 scale by RNinMunich Fleet Admiral!   Posted: 13 days ago
Thankyou Nerys for your very kind words 😊👍 'One does what one can!' 😉 HMS Manxman is one of my favourite ships and the subject of my next major project. I have the 1/96 scale Deans marine kit. Her history has always fascinated me. Built my first 1/600 Airfix model of her many many moons ago! Should you happen to have any photos of her in the Medway I would be most grateful if you could post them or mail them to me👍 Re 'the wealth of information'; comes from having spent over thirty years working in naval communication systems for navies and shipyards around the world. Many of the projects were refits of ships which were built towards the end of WW2. Such as the ex RN Colossus class carrier I worked on in Rio de Janeiro. Ex Vengeance then NAeL Minas Gerais. Pics show her as built as Vengeance and as rebuilt / reconfigured as Minas Gerais as I knew her in the nineties. Through that work I developed a knack for research; if I didn't know something about a ship or a COMMS process that a customer wanted I damn soon found out. Was essential to stay ahead of the competition 😉 It also gave me an undying interest and insatiable curiosity about the history of the ships and the men who sailed and fought in them. My first working model was a scratch build of the H class destroyer HMS Hotspur which I built at 1/72 from measurements taken from a 1/600 Airfix kit, when I was 15! 52 years ago now 🤔 See penultimate pic, shows her alongside my 1/72 Type IIA U-Boat. A contemporary of Hotspur, both commissioned in 1936. Last pics are of her maiden voyage in Radnor Park Folkestone in 1966. Sorry, only had a Brownie 127 camera back then 😁 Her history, from Narvik to Dominican Republic was also very chequered and eventful. Like Manxman, despite being severely damaged several times she survived until the early seventies. Apart from the Manxman kit I have recently found a 1/350 kit of the Colossus class carriers. So I promptly bought two of 'em. One I will build as the original HMS Vengeance, the other I will try to reconfigure as NAeL Minas Gerais with an angled flight deck etc. Wish me luck 😉 Good luck with all your projects Nerys and All the very best for 2019. Cheers, Doug 😎 BTW; footnote to SS Peking; German TV recently showed the old Miss Marple film 'Murder Ahoy' in which the Peking was used for the external scenes as the Training Ship Battledore. An amazing coincidence, following so soon after your enquiry!

All hooked up, nowt happens... by DodgyGeezer Lieutenant   Posted: 19 days ago
".. Worked through the instructions and it made beeping and squawking noises in what seemed the right places but still no reverse. The increase in revs does now cover the whole of the stick travel above the mid point so I has changed something. Lost the will to live after 2 hours so went and worked on something else. Steve..." Just a thought - may not be applicable, but we often share our reversible ESCs with the car fraternity. And some of them have an odd reverse. For some cars, you may be happy with straight forward and reverse, but for racing this is not ideal. Dropping into reverse if you move the stick/trigger back past neutral would make the car uncontrollable on a corner. Instead, the racing car boys have a system whereby the forward stick increases speed, while 'reverse' performs dynamic braking by shorting the motor terminals (or perhaps even regenerative braking!). To a boaty, this would seem as if the forward stick worked, while reverse did nothing. These racing car ESC programs DO allow a proper reverse. The way you usually get to it is to bring the stick back to reverse, then forward to neutral, then back to reverse again. It's a two-stage process - call for reverse twice. If you go into reverse, then forward, then back again you won't get reverse - it has to be reverse, neutral, reverse. Which is fine if you are manoeuvring a car into a parking space, but rather clumsy for a boat....

Kingfisher by Norstar upgrades by Ron Fleet Admiral!   Posted: 20 days ago
Hi Joe, Happy New Year. We have a frozen lake here in Ontario and this set up will be first tried out in the spring. This motor pulley system was recommended to me. Will keep you posted.

fuses by teejay Commander   Posted: 24 days ago
Thanks Doug and Donnie tried the 15 amp fuses all went well the boat is ready for the lake. and thank you all for the help and advise during this build over the past year I really don't think I could have managed it without your input. the next stage is going to be replacement of the brass rudders and some work on weight saving and some pic on the RC system. and making a suitable box for transportation. that will kept me occupied till the better weather. So thank you all and have a merry Christmas and happy new year and a good hangover cure and may your god be with you in all your sailing

Excelsior by Gascoigne Captain   Posted: 26 days ago
Hi Joe, In answer to your queries, Hull was built in the bread and butter system using deal sealed inside and out with coats of yacht varnish and painted using acrylic. Subsequent models of Wherries and Chinese Junks were plank on frame using 1/8” balsa strips sealed with resin,varnish inside and out, with again acrylic paint. Balsa easier to work with to gain experience - reasonable effectiveness both in carvel and clinker planking. All the best and good sailing. Gascoigne

How to RC small boats? by DodgyGeezer Lieutenant   Posted: 29 days ago
There's no great need to dismantle a servo to get motive power - nowadays you can buy model motors that are not much thicker than a typical boat propshaft, and speed controllers the size of a thumbnail. Usually for about a pound. These small drones have really helped in this regard. This one, for instance, is 0.6cm diameter by 1.5cm long - https://www.ebay.co.uk/itm/Original-JJRC-H20-RC-Drone-H20-08... Your biggest problem will usually be rudder control - there will be little room for a servo and tiller right at the stern of small boats. For an EeZeBilt I recommend a closed loop system which lets you relocate the servo anywhere convenient - see http://eezebilt.tk/radio.html The EeZeBilt Terrier below is 10.75 inches long...

App pages not loading by Brianaro Sub-Lieutenant   Posted: 29 days ago
Can anyone help please? Whenever I view this App on my phone or iPad, I can load the first and sometimes the second article but beyond that the pages won’t load. I have the current version of the App and current version of operating system. I’ve tried closing and reopening the App but the page still won’t load, I’ve uninstalled and reinstalled the App and still the problem remains. I’ve contacted the site several times but had no reply. Does anyone else have the problem?

Anteno 2 tug by Joe727 Captain   Posted: 1 month ago
mturpin, Thanks for the idea with the cooker hood or vent hood as we say in the states. Great idea and I too could use a better system to solder under, nice to combine both paint both and soldering in one as I have just a tiny shop, Joe

steam water pump by GaryLCoupland Chief Petty Officer   Posted: 1 month ago
Good Morning Rick, well it is here in the U/K. out of curiosity, I had a look at your profile as I imagined you were young and just starting off with steam, at least I got the second bit right and discovered you were of 1947 vintage, easy to figure out as I am from 1946. That was a bit of a shock to the system, anyway I thought I would share with you the fact the TVR steam engines are manufactured in the US of A, across the border by Graham Industries, almost on your door-step so to speak. Regards, Gary.

Thunder Tiger Avanti by boaty Admiral   Posted: 1 month ago
Has anyone done any significant modifications to a Thunder Tiger Avanti fast electric? I have one and all I have done is to replace the nylon prop with a metal one thus there is very little increase in performance and the reason for doing this was due to the nylon prop throwing a blade after striking an underwater object. Prestwich Model Boats have a suitable replacement motor complete with a better ESC than the existing Ace one and their system can handle up to 4S Lipos instead of the stock set up of 3s . I have located a source of a 4S Lipo which length and width is same as my 3S one but the height is a little more and it will fit into the battery box. To trim it out properly I would have to add some ballast to the starboard side. Due to the electrics including the battery all being in a small watertight box at the stern there is not a great amount of scope for a lot of mods. Boaty😁
