Sea Scout 'Jessica' Sea Trial - at last! by RNinMunich Fleet Admiral!   Posted: 2 days ago
Part 1. Ideal conditions; nearly 30°C, cool Bier at hand😜 Sea Scout built by Dad in the early sixties with a Taycol Target and 6V lead acid wet cells (very wet😡). Renovated and dragged into the 21st century over the last several months 😉 See Build Blog 'Sea Scout 'Jessica'' for details! Motor: Propdrive 2830, 1000kV, 30mm 3 blade Raboesch prop. Quicrun 16BL30 (30A) ESC with BEC. Tested with 3 battery types, all started with 99% measured capacity- 1. NiMh 4.2Ah 7.2V, nom. 408gm. Result: Speed sedate (OK 😉scale river cruising!) No planing. Max current: 3.6A End status V / capacity left: At end of short run ca 3 mins. 7.78V 99%. 2. 2S LiPo 4.0Ah 7.4V nom. 257gm. Result: Speed still sedate but due to lower batt weight at least the forefoot came out of the wet stuff! Max current: 4.1A End status V / capacity left: At end of short run ca 3 mins. 8.25V 93%. 3. 3S LiPo 4.0Ah 11.1V nom. 315gm. Result: Now we're getting somewhere!!😁 Good speed, manoeuvrability and planing 😊 Max current: 7.5A End status: 11.95V 74% after several long runs, ca 20 mins total. Estimated (extrapolated) endurance on a 4Ah LiPo around one hour - mostly 'full bore' - 'Pedal to the metal man' 😊 See also: https://youtu.be/oMUlSOaAREM The competition! https://youtu.be/zPgYicA0yGw Final run. (Beer was getting warm😁) Cap'ns log entry: Boat dead-weight w/o battery: 1.8kg. Spray rails to be added!😲 Slight list to port to be trimmed. Rudder servo to be reversed!!😲 Keel protection to be added: some scratches and flaking from stony sloping shore 🤔 Summary: much as expected👍 Forget anything less than 3S. Anyone want to buy a batch (4) of new 2S 4Ah 45C Lipos? 'One careful owner'! Happy boating people, Cheers Doug 😎 PS Many thanks to Camera girl Gisela 👍 Recorded in 1080p HD.

Duke of Cornwall by Neil-S Seaman   Posted: 3 days ago
[Score: 8/10] 51"/7000g Duke of Cornwall Capable of 4mph and a runtime of 30mins Twin Propellors (3 Blade 20mm) Direct Drive to a Torpedo x 2 (3 Blade) Powered by Lead Acid (12v) 6Amp/h Batteries Controlled Through Electrinize (5Amps) ESC - Comments: This was a static scratch built model constructed by a model engineer probably in 1970s, I was gifted the boat by the local RNLI Branch with the proviso I looked after it and occasionally displayed it on Flag Days. The boat is a model of the Lizard and Cadgwith lifeboat 'Duke of Cornwall' which saw service for 20 years and saved 95 lives. I have fitted 6 channel San,wa remote control and the Torpedo engines and batteries. She runs very well on the water and achieves a good scale speed when both motors are at full power. Batteries are 12 volt gel type and new, I have never had a problem with endurance. Control is by two Electronize speed controllers which plug in independently to receiver. She has a two tone siren, worked from retract servo switch, which is useful for clearing a way through birds. Steering (like the real thing) was rather sluggish, a single blade rudder but it improves by using the two engines. She is pretty heavy to lift into the car, I use nylon strops to lower her into water. I have done several adjustments to her topside so that she more correctly resembles the 1962 Barnett lifeboat she is modelled on, main adjustment was to put mahogany veneer onto to forward and rear bulwarks, as the originals had. The original boat topside was painted grey and it was only later that areas were painted orange, she is a non self righting lifeboat one of the last of this type and modifications were made in the mid sixties to seal off the rear doors and provide a watertight compartment, as well as fully enclosing the wheelhouse (the model's wheelhouse is open at the rear, as was the original. All hatches and doors open. The railings are chain link and seem to be a very good match to the ones fitted. My only issue at the moment is the radio wires which seem to be very vulnerable, have used electric thread but not a great solution - something to look out for. I have purchased 3 crew and am about to paint them, two will be in the wheelhouse.

getting a bit slow?... by Westquay Fleet Admiral!   Posted: 5 days ago
Sorry, I didn't realise there had been any follow up to this. (May I suggest a "View New Posts" button? Or am I missing something) I think my remarks a year ago were perfectly valid, now you remind me of them. I thought I'd been offensive or something. I see no cause for offense there. Teejay, you, too, have misunderstood my post. I was saying why I had left model railways, a hobby of a lifetime so far. THAT alone was the area of kit snobbery. Not here, or in model aircraft forums, which are nearly all kit based, yet I am a happy member of Large Scale Planes and Britmodeller. Mainly because two old friends tend to communicate with me that way. Doug, I have a 1/48th scale Mk1 Airfix Spitfire which I have turned into the First Flight in zinc chromate and polished metal, because I don't do military (liveries, at least) and have made a scratchbuilt photographer and his plate camera for the set-piece. It all sits on a bit of died lint grass. Then I have a 1/48th scale Airfix English Electric Lightning as it's a superb kit and impressive in that scale. I got it cheap off ebay. I also bought an Italian resin kit of a Houchin start-up compressor to go with it, which was amazing value and have made a tarmac set-piece ready for displaying that lot on. It was purely to save time getting something I just fancied doing. It's the foil covering on the Lightning I fancied doing. No snobbery there and when others buy loads of aftermarket stuff to add to it, none there either. And they usually make it all fit themselves. They don't pay someone else to do it. If injury or health demands it, that's a very different kettle of fish, but those sort of people rarely, if ever,brag. So, once and for all, nothing I said this time had any reference to this forum or this hobby. What I said a year ago I meant, but perhaps it was a bad day. I always read what I type as my hard, dry old fingertips slip around the keyboard and I wouldn't understand my own typing if I didn't check it. Doug has indeed helped others and me too. But so, I think, have I. Indeed that has always been my intention after a lifetime in modelmaking. Cheers, Martin

Fun Run by Donnieboy Fleet Admiral!   Posted: 7 days ago
Our club had our Fun Run today.We operate out of Humber Bay in Toronto whilr the weeds are down.The sun is finally cooperating. We have two ponds to run our boats in.The Sailors run in the big pond and the scale members run in the smaller pond.Attached are a few photos of the day.I must mention that the first picture is a new construction of a Marblehead out for a test run.The Canadian Coast Guard Ice breaker is totally scratch built with working radar and lights.This member works on his kitchen table.We found out later that he was born on a kitchen table.

getting a bit slow?... by teejay Lieutenant   Posted: 8 days ago
Hi all I am quite disappointed seeing what has been written on this forum these last two days , this is the only forum I have used because there is little or no snobbery until now , and RN Munich is right , I have been making kits all my life since the age of seven and like most modeller my skill set has changed in that time , I have adding too and modify kits most of this time and a lot of it involves a good bit of scratch building to meet the specification of the various marks of different aircraft , I have done this for the syllabus for two ATC squadrons, and for presentations for RAF veterans. and while I do fine the remarks made by Westquay offensive snobbery I would not like to see an end to RNinMunich posts as I now he helps a lot of people that may struggle, with all aspects of the hobby , I think that if you cannot refrain from criticizing others unconstructively may you should use some other site that seems to specialises in slagging each other off

getting a bit slow?... by RNinMunich Fleet Admiral!   Posted: 9 days ago
Martin, maybe you should read back what you wrote before you hit the 'Post' button? " over-pensioned old fools who spend a fortune on some very average kit and another on wheels and gearbox, motor, building, painting, lining, weathering, blah, blah and finally bragging about on forums. Kit snobbery is not only annoying, but to a scratchbuilder like me it is utterly stupid and pointless." Nobody here to my knowledge has bragged about the cost of their kits. Wilfully misunderstood?? It's not necessarily what you say but the way that you say it. I agree with much of 'where you are coming from' but not how you express it sometimes. Comes over as a bit of a tirade. Apropos Airfix: I recently succumbed to a 1/24th scale Mosquito, my Dad's second favourite plane to work on and fly in, after the Spitfire. Man is that kit huge! Which Lightning do you have? the P38 or English Electric? I built both years ago, but only 1/72, they didn't come bigger in those days. Cheers Doug 😎

getting a bit slow?... by RNinMunich Fleet Admiral!   Posted: 9 days ago
Good ol' Martin, you haven't changed a bit have you? But then why should we at our age? Just as forth(or fifth?)right as ever😉 Was mildly surprised to see you pop up again a year after you so explicitly and expressively announced your departure! Getting bored? What might seem "utterly stupid and pointless" to you, as a lifetime professional model builder, is a very satisfying and maybe only possible way for many of us to enjoy this hobby. Is it really necessary to denigrate kit builders in this insulting manner? Some of us do a mixture of scratch and kit building, sometimes for the fun of building, sometimes for convenience / speed, as a a fill-in JFF job during a bigger build project, or because the scale is smaller than the 'small scale' of 1/48th you mention. I.e. working models at 1:350 or 1:400. Even then we fiddle about with embellishments such as photo etch, which itself demands certain skills. Even kits demand certain skills, especially the larger more complex ones. My next 'average' kit build will be a 1metre Akula II Russian submarine with diving tank for static diving. Utterly stupid and pointless but a great challenge and ultimately great fun I hope, with a built in mini video camera. A way down the line as other wooden boat restoration projects are still on the slipway, but something new to try. Maybe you should do that sometime? Have fun with your dogs. Viele Grüße aus München, Doug 😎 Oh! and QEND - Quad erat non demonstrandum! BTW: nice work on the Vanity woodwork, thought you had her finished long ago though. Did you ever get your old Taycols out of your son's loft?

getting a bit slow?... by Westquay Fleet Admiral!   Posted: 10 days ago
Winter used to be model railways and slot cars. Now just slot cars and small scale static boats, 1/48th scale. I always promised myself a collection of 1/4"-the foot inshore craft. I really can't be doing with the over-pensioned old fools who spend a fortune on some very average kit and another on wheels and gearbox, motor, building, painting, lining, weathering, blah, blah and finally bragging about on forums. Kit snobbery is not only annoying, but to a scratchbuilder like me it is utterly stupid and pointless. And as a model railway club near me now charges 100 quid to join and still only turns out a glorified toy train set, it is, alas, no longer a hobby for me. We have a sign on our wall that says, "The more I learn of people, the more I love my dogs". QED. Martin

Scudder by Grumpy1949 Sub-Lieutenant   Posted: 10 days ago
scratch built old Vic Smeed plan. needs either bigger motor or more pitch. should go better once it gets on the step

It's a sad day!. by BOATSHED Fleet Admiral!   Posted: 14 days ago
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.

Clyde puffer by RNinMunich Fleet Admiral!   Posted: 17 days ago
Eveni' Marky, Re Tights! What's handy will surely depend on the Missus or ..? 😉 Frankly I would dispense with the tights altogether (the Missus may of course have a different opinion😁), more trouble than they are worth and don't contribute much or anything to the construction if the basis was soundly built. It only costs you more resin to fill in the mesh of the tights. If you must use tights then the higher the denier the better (at least 40 - 50) anything less will have a very open mesh and contribute virtually nothing to the hull strength, the Missus will explain denier to you This seems to me to be a 'hangover' from 50s style construction when glass fibre was more expensive relatively speaking. I tried it back then with a scratch built Sopwith Camel fuselage and it was a total disaster. Instead planking with 1/32 balsa and a thin resin coat worked a treat. Nowadays, 30 years or more, I use glass fibre tissue instead; density and therefore strength imparted to the hull is more even cos it don't stretch like tights! Whatever, have fun, and greetings to the Better Half (tights donator!) Cheers Doug 😎 PS: if you feel you need tights😲 (or FG tissue) fit the rubbing strakes after this, and after sanding the tights / tissue to shape. Otherwise the strakes will just get in the way and be a nuisance to sanding and will get damaged / deformed. PPS: shame about the amber nectar, my commiserations 🤔 My current tipple is more tawny port colour; a rather nice Lagavulin 😜

Our boating water by RNinMunich Fleet Admiral!   Posted: 17 days ago
Hi Boatshed, you could also simply chat with the sub skipper (or vice versa of course) and coordinate your actions!? I've also once witnessed here in Munich a maniac power boat driver ramming and completely destroying a clearly visible and magnificent tug model only about 15 feet offshore! The tug had only just been launched on it's first sea trial 🤔 I must also add that I do intend to add an orange sphere to the antenna or scope of my Akula 2 so I can track it at periscope depth, below that I don't normally expect to meet anyone! If other subs turn up I will talk to them. Happy sailing all, cheers Doug 😎 PS generally sub drivers have an alert eye open for other boats, especially power boats! PPS I've also seen several 'proud' owners of RTR plastic so called 'power boats' who've looked pretty sheepish when my 30 year old 1.35m scratch built H class destroyer or 1.07m U Boat have out run them 😁

Scratch build twin pontoon water jet boat by Grumpy1949 Sub-Lieutenant   Posted: 18 days ago
Hi fellow mariners, winter approaches time to get a couple of projects under way. Is there a general rule for the positioning of the pontoons in order not to flip over at speed. I am using a nqd water jet for propulsion mounted in the centre hull. The pontoons will be hydroplane shaped with a step half the length of the lower surface. Aluminium tubes will run from one pod thru the main hull into the other pod. There will not be any panel shrouding between the pods and the main hull like a true hydroplane. Overall length about 30cm not sure of the width yet. Have seen a few foam builds on utube but really no help. Any help would be appreciated Gordon from downunder😆
