Evenin' Martin, Just back from 'nosh' with Gisela, my camera girl in the vid! She's mean like that too, keeps me hoppin' about like the proverbial cat on the proverbial hot stuff 😡 Can't wait to see the rotating teddy👍 Put a couple of mini Cam lenses in his eyeballs and you'll get a terrific 360° First Person View from the driving seat😁 Re Sea Scout, I took your advice and did the hull in Royal Blue (no navy knickers!😆) or what passes for that here. Anyway I'm pleased how she turned out. OK, I admit I accidentally turned her into a Sport Fishing Boat😁 She's 24" what scale do you think that makes her? I'm looking for crew figures and stuff to fit out the cockpit but I'm not sure what size to look for. I thought maybe 1/20 i.e. a 40 footer? Waddya think? Re Kako; while recently trying (fruitlessly🤔) to make space in the workshop (got two renovations on the go in parallel - saves getting the same tools, rattle cans an' stuff out twice!😁) I ran across the original Kakos and Mabuchis I used in my scratch 53" H class destroyer Hotspur in 1966. She ran off a 4.5V EverReady flat (form not volts😁) battery until Granny took pity and bought me some 6V Lantern batteries! I ran 'em up on a power supply and they turned but now sound like mini football rattles! Think they need new big end shells 😁 Jeez, how many guys under pension age have ever been down to the bitza bazaar looking for 50 thou oversize bearing shells and compression and oil control rings?? Pics show her Sea trials in Radnor Park pond, Folkestone, Kent, summer 1966. Sorry about the quality, only had a Box Brownie 127 in those days and could only afford Gratispool free B/W films🤔 Pentax? Canon? Sony? Not to mention Digital? HD? Wassat? 50 years on I got all three😉 I like Lupins too, preferably the blue and purple ones. BTW, for your steering guy's arms you don't need a separate RC function or channel! You just need a coupling from the rudder control to turn a pulley and cord which turns a suitably scaled pulley attached to the wheel axis. The arms are fixed to the wheel and go with it! Dead simple (to write anyway😁) and no lecktrickery! 😊 OR you could just put one of his hands on the wheel and the other on the throttle. Then use a 'Y' cable to split the ESC cable into two. Connect the second output to a servo which moves the throttle lever via a push-me-pull-you-rod, pulleys and cord or gears or whatever. Sure you can figure out the mechanics better than I. Whatever, have fun and don't electrocute yourself, keep your socks dry😉 Cheers, Doug 😎
Haverlock, so when The servos don't don't want to work any more, it's time to recharge I take it? I don't know how else you could tell. Because they have an RC plug on the wire I can't try them out in the DAB radio or my camera. As to the binding problem, yes the plug is in because I have never removed it as I wouldn't know what to do with it. Martin
Doug, Gawd bless yer , Guv'nor, I knew you'd come through with the advice on electrical stuff. My Dad would be ashamed of me as that was his game, but I could never raise interest and therefore retain any knowledge he ever imparted to me about it. A wall wart is what I've seen those little plug in the wall chargers that do 4 AAs or AAAs and charge up overnight described as, mainly by overseas chaps. They do, however become alarmingly warm sometimes, but do a good job for my camera and my wee digital radio, so I can always catch the Goons or the Navy Lark on BBC 4 Extra, or some good new music on Guy Garvey's programme on 6Music. So they work, but I have a pack, now, pre soldered, of 5 cells. My Orange Rx and servos are happy with 6Volts or so their blurb says. I'll look up a battery condition meter and get one. I just ordered a Multimeter to just do volts. Always a good adjunct to a household anyway. I have my Dad's two Avometers in their original leather cases, but can no longer get the high voltage batteries they contain. Found a miniature Avo in a smaller leather case, but don't know how to use it. I hope you can get some sense out of the words and music for the imax B6 charger. Off to eat myself (eat myself?) Eats, shoots and leaves Martin
Thanks Rooky 👍👍 I'll pass on your compliment to my 'Camera Girl' Gisela 😉 When were you in the Ostpark?? Might be back there this week for a test of a PTB 'as bought' before I renovate it and convert it into PT109. Cheers Doug
The funnel was made out of 40mm plastic waste pipe, let into a piece of 3mm plasticard, thin strips of plasticard super glued around to simulate the sections. The hatch at the back made with plasticard, hinges and handles again made out of plasticard. There are four stop cocks at the front, the bodies of these were made out of aluminium on the lathe, with 1mm rod and some hand wheels out of the scrap box. There are four stays to hold the funnel and one at the top that goes to the aft mast, small hand rail knobs were used for this job. The funnel was painted (no it isn't pink, its the flash from the camera that makes it look pink) small brass tube to the steam whistle and the whistle made out of a bigger dia tube, a ladder added out of the scrap box and the completed funnel ready for fitting
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.
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
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?
Picked up a rather battered wooden hulled Amsterdam tug last Thursday. The intention is to give it some much needed TLC and convert it to one of the French Tenace Class tugs. It will be used as my clubs camera / rescue boat so accuracy and detail will come second to the functionality of its role. Currently I have stripped out everything except the motor so I can fit some strengthening and improve the watertightness of the hull
Thanks Chris, entirely understand re downloading pics from camera. 😁Those blue jobs look neat, haven't seen any like that over here - yet! I have 'oodles' of the little X clamps you've also used and a few mini alu G clamps. They are virtually thrown at you at the check outs in the DIY stores here - bag of 12 for a quid or so. Wish I could get to the IMBS 🤔 Re quoting posts; "PS Is there any way of quoting posts on this site as I haven't sussed how to do it if you can?" I haven't found any more elegant way of doing than that! Copy and paste (Control+C and Control+V) and putting it in quotes in the new post. Happy clamping 😉 Looking very good so far, cheers Doug 😎
You are absolutely right Doug but it was quite late with work (getting there, down to 3 days!) the next day and couldn't be ars@d to get the photo off my camera! But photos attached with other clamps pressed into action as well as only straight pieces of timber and not as much force required. I picked up those one-handed clamps from the International Model Boat Show and they are good as well but I only have two. Chris PS Is there any way of quoting posts on this site as I haven't sussed how to do it if you can?
Hope you get the result you deserve, I do all my testing on a 28acre weed free lake that is designated a wildlife sanctuary. It is also used by model flying boat club. And have not had any incidents in the twenty years we've been using it. Some bird watchers have even asked if we can carry a camera on the boats to film birds on the water and islands. The birds don't seem to mind. Cheers Colin.
Thanks all for the words of encouragement and the leg pulling. I have no idea what happened. The pictures on my I Phone camera are all the right way up, I was not drinking or smoking anything and cannot be in the Antipodes as temperatures are still below freezing. Pity the thumbnail picture when uploaded was not bigger, might has spotted the error then. Anyway, Me Culpa!
Thanks Dave, Eventually we will have put together a body of knowledge that model boat builders can use with some certainty. At present the information is sketchy, hard to find and sometimes ambiguous. The motor designers and manufacturers have not been very helpful. For my La Combattante iii missile boat I used two Hobbyking Keda 720kV motors rated at 215 Watts and 19.3amps max. They were the first brushless motors I tried. I was not sure how many amps they would draw, so I connected an ammeter and fitted my video camera so it read the amps whilst operating. At full speed they used only 8 amps each. Each of the batteries is from 12V made from 9 x NiMH 9Ah D Cells. I easily get over an hour run time at good speed. The boat is 1605mm long so not small. This information may help someone.
