    Friday's Child Fairey Huntsman 31
    Hi Stuart, At 23" your Huntsman is only a tad smaller than my 24" Sea Scout which I refurbished last year, look for the build blog 'Jessica - A Sea Scout
    restoration
    ' on this site. I fitted a 1000kV 28mm Propdrive motor and Quicrun 16BL30 30A ESC from Hobbywing. including the ESC programming card the whole kit an' caboodle was just under 40 dollars from Hobbyking.com. With a 2S LiPo (7.4V) performance was sedate to adequate. With a 3S LiPo performance is 'twinkling' and a lot of fun to drive. Check out attached video links. Pt1: https://youtu.be/zPgYicA0yGw First run with a 3S LiPo. Pt2: https://youtu.be/oMUlSOaAREM 'The competition'! Pt3: https://youtu.be/b0BWJ3duzDw 'Final run', the Bier was getting warm Prop is a brass 30mm 3 blade from Raboesch. Hope this helps, Happy Sailing. Cheers, Doug 😎 PS Video is in HD 1080p, taken at the Ostpark Lake in Munich (adjacent to the BiergartenπŸ˜‰πŸ˜) May 2018.

    Fairmile D 1/24 Scale Build
    Hi John, You seem to have missed the point entirely, as you also did with your first post on this thread, in which instead of trying to help Andy and answer his question you attempt to dissuade him from his goal. Unfortunately I missed Andy's question back in March as I was embroiled with family matters. BUT, if he hasn't in the meantime been 'scared off' by the lack of constructive response I will do my best to help, having several times been down the road of multiple screws, as have many other better constructors than me on this site. Nearly all my ships have two, three or even four screws. Only the Sea Scout and ancient Billing Boats fish cutter (a
    restoration
    and conversion from static to RC project) have single screws - as per originals. About a year ago I acquired a model of a US Elco PTB fitted with two shafts. I am restoring it, rebuilding as Kennedy's PT109, and will fit the third shaft to complete it to scale as per original. Why? Because that's what scale modelling is about and because it's a challenge - pushing limits. Far be it from me to decry or put down anyone (as you now seem to be trying with me). We all have the enthusiasm (or we wouldn't be here) and do the best we can with the skills nature gave us and what the budget and state of health allows. I have often been astounded and appropriately applauded, and supported where I can, what fellow members have achieved with very limited resources and under very different circumstances from those we in the so called 'Western World' enjoy. That guy in Bangladesh blows my mind with what he manages in the back of beyond! Look for his post about his March '71 boats. WHEN I pitch in here I try to do so with constructive assistance, drawn from my own modelling experience and a lifetime spent working with navies and shipyards, to help a guy achieve his aims and dreams. NOT to immediately deflate him by saying 'Why do that? I did mine this way, it's not what you want but it works for me'. So far the Likes, PMs and mail feedback, request for assisitance I have tell me I'm doing something right. if I do boob (we're all human) I'm prepared to admit it and make amends / corrections. I have no idea what this 'Hooben' is that you yatter on about BUT - if "every little detail (is) reproduced with superb accuracy" why then ruin the overall effect by not continuing this attention to detail on the underwater ship and fitting shafts and screws appropriately? Whatever you do have fun with it, but don't dissuade others from pursuing their dreams. True there are "many roads to travel before one reaches there (!sic) destination" BUT as Confucius said "Every journey begins with the first step." if at the first step someone says 'Your destination is the wrong one' instead of offering a roadmap ..... ! Regards, Doug 😎 BTW: still waiting for the pics / videos of your 'Hooben' (?) and the Perkasa.

    Anteno 2 tug
    Hi Dick, To 2nd plank or not to plank - your choice but regarding the improvised spray-booth - Your storage container, neat idea, may prevent you from colouring the immediate surroundings, but it won't stop the vapours, explosive fumes and overspray dust from rebounding back into the room. 😑 Ask me how I know πŸ€” To prevent that your storage container needs an extractor fan coupled to a vent pipe leading to the great outside world! DIY nuts can construct such using the guts of an old vacuum cleaner. I was about to try that when I stumbled across a booth with extractor and vent pipe at a reasonable price on the German Conrad site. https://www.conrad.de/ Have used it to good effect on my Sea Scout
    restoration
    . 😊 In the attached pic one can see it behind the freshly sprayed hull of my Sea Scout. To the left is an additional filter/fan to absorb any overspray that flies out of the little booth. I also use that when soldering with my ancient lead based multi-core solder. Happy modelling - but stay safe Guys πŸ˜‰ Cheers, Doug 😎

Not too expensive and seem to work 'as advertised' πŸ‘ When you read the blog you will realise that I did not build the kit (and that I have a nutty sense of humour😁).

I decided to convert that to work with a modern reversible ESC and fit it to an ancient Billing Boats fish cutter that I am slowly restoring and converting from static to working model. Last pic shows the initial 'trial fit' of the motor. The motor

    Old outboard motor...
    Hi Doug, I do have a Hobbyking CNC ally one and now have a brushless inrunner for it. I got it when they were very cheap a while back. Wouldn't pay what they now want for them and Graupner are always way overpriced. I could be tempted with 7 quid for a Hobbies one though, just to see how it goes together. The K&O are gorgeous but collector money and the Alterscale are dummies, albeit nice dummies and also bloody expensive. I sliced the little vintage jobby I bought down the joint line with a fine saw blade in the minidrill today and all is well. it just needs new wires and some grease when I can find some good styrene/nylon grease. The motor is a two magnet Kako, many examples of which I have in store. Even has a nice little built in switch. I reckon 3 volts is probably all the transmission can take. The gears are not, as I assumed bevels, but 2 spur gears! I now have to find a way of making the prop shaft stay on the motor shaft! I'm loving this

A good little sailor, light in weight and a good pond model. Had to be careful of wave height. Anyway, it has been in the garage for 40 years now so much to do.

    My answer would always be if the engine starts easily, use it and the hell with jobswuffs who would tell you no. Just don't ask. Go when nobody else is around. if its a natural lake it maybe doesn't belong to anyone, so go ahead. if the owner can prove it can't be used, by proving he IS the owner, then desist and find another body of water. There are quite a few in Wales after all. Alas, if you join a local club they will be bound to say no IC engines. They nearly all tend to now, whether they have the right to or not. I'd say leave them alone and enjoy yourself on a river or natural lake. Only if you just cannot find anywhere to run IC should you give in to electric. Good luck. Martin The Anarchists Boat Club.

    s of early (50 year old) Monogram slot car bodyshells. And I have 2 ancient Marinecraft hulls for which various repairs were necessary. One, I have made a very Ditchburnish gent's racer superstructure for, as I had no details of what it was originally like. Canabus, could you explain S,K&G? I keep seeing it, but have no idea what it is. Martin

    You're dead right HammerπŸ‘ This is my second renovation / upgrade and the third, a 28" PTB is also already started. I must be nuts! But then, that's a prerequisite for model boaters ain' it!? Following your 'mechanical engineering' with great interest and awe! Cheers, Doug 😎

    Over Spray!
    Hi Ed, a drop of appropriate solvent should get it off. Or polish it off with paint cutting polish from the auto branch, like I used on my Sea Scout

    Great job your doing Doug. I think its more of a challenge renovating an old model than building from scratch.

    Thanks Mike, any other questions I'll be glad to try to answer. Maybe I'll start a micro-Business making the conversion boards 😁 30 years ago I used to make my own etched printed circuit boards, maybe I should refresh that skill!? πŸ˜‰ Hope the info is useful, as a 'dumb' electronic eng. I'm learning a lot from all you 'mechanical wizards' as well. Makes for a great forum site😊 All the best, Doug 😎

    Evenin' Mike, Glad you found it interestingπŸ˜‰ The details of the motor conversion are in my Sea Scout renovation blog but the essentials are- All modern ESCs provide a DC output in the form of pulses which are rapidly switched on and off ( several thousand times a second). That's what you can see in the scope pics. The scope timebase (width of one horizontal division) is set to a little less than 1msec so you can see how fast the pulses are switched and how the pulse width (ON time) varies. The inertia of the motor keeps it going during the few milliseconds of 'Off' so the ratio of ON pulse to OFF determines the speed of the motor. The signal from the TX varies this ratio by varying the ON pulse width of the ESC output in proportion to the throttle stick position. A Bridge rectifier is simply 4 diodes arranged in a square (see pic) so that it has 4 terminals; +, - and two AC (~). When an AC signal is applied between the two ~ terminals a DC voltage of constant polarity appears at the + and - terminals. The rectifier sees the ESC output as an AC signal and produces a DC output at the + and - terminals. All I do is apply that constant DC voltage to the field coil of the motor, thus creating a constant magnetic field as if it was a permanent magnet. This means doing a small mod to the motor to separate the field coil from the brush gear and rotor (armature) coil. 3rd pic shows normal wiring of the coils in series. Meanwhile the varying pulsed voltage goes to the brush gear (and thus armature coil) driving the motor just like a normal 'can' motor. No rocket science just a neat trick πŸ˜‰ The scope just shows the varying pulse train from the ESC to the motor. Zero Volts is on the horizontal centre line of the screen and shows when the voltage pulses are positive (upper part of screen) or negative (lower part of screen) and the motor reacts accordingly. The slight overshoot is probably due to the reaction time of the diodes but the motor doesn't notice that - it's too 'lazy' πŸ˜‰ Here endeth today's seminar 😁 Hope it's demystified things a little. Cheers, Doug 😎

    Evenin' Mike, guess you're right πŸ€” Bit of a departure for me I admit, and after I'd cleaned all the crud off and realised how shoddy and weak the hull was I wondered if I'd bitten off more than I can chew😲 However progress has been made😊 I hate to be beaten! See next update 'Motorisation - Come What May!' You'll recognise the topic from the discussion on dies and threading silver steel prop shaftsπŸ˜‰ I'm multiplexing this project with a PTB renovation and refit! Like most boat modellers 'a glutton for punishment'. Cheers, Doug 😎

    That's going to keep you busy for a while, however a most enjoyable project, I look forward to seeing its progress.

    Spektrum, new, useless...
    Ah, OK. I am so anti military, I can't even think of all that stuff, although I am very anti-working features on models. I find them a bit nafferoony on the whole. Go, stop, left, right, that's me. I ain't even bothered about backuds. Goes with my free sailing/IC/early electric background I suppose. Lights only needed at night and I wouldn't be sailing in the dark. Smoke looks like some old geezer having a fag under the deck.....I know you'll argue. Anyway, for my sort of model, a third channel is a waste. And as it's a switch, I couldn't even use it as a jib hallyard. I'll try ringing the service bloke if I can find him. We'll see what he wants to charge, but with postage it'll be silly probably. If you'd like me to do you a shaft, let me know. I have loads of 3mm silver steel for my old American slot car
