    Construction of a smoker
    Click on (see all discussions) in the topic forum then go to page 16 and look for smoke
    . I hope this is the one. Or type in the search field (smoke
    ) Martin555.

    (Working Vessel) Eppleton Hall
    Still in the process of building a 32nd scale model of the paddle tug "Eppleton Hall" from scratch, for the most part. (Motor: 540 MFA 919D) (ESC: VIPER Marine 25) (10/10). All electronics have now been installed including 2 motors, 2 ESC's, a small smoke
    , a sound module and speaker, a rudder servo, a distribution panel, all running off a 12V gel cell.

    She is a great model but could do with a smoke

    Sternwheel paddle boat 1 hp
    Brilliant Rooky๐Ÿ‘ Question! Is it direct drive from the wheel? If so how does the speed controller work? Heating in the wheel for faster? Servo controlled sharp stick? ๐Ÿ˜ฎ Freezing for slower?๐Ÿ˜ Or vice versa? Or does he charge the battery via a
    ? BTW: where is his life jacket ? SOLAS regs don'tcha know Warrant! Cheers, Doug ๐Ÿ˜Ž

    Magnetic motors
    Morning Doug Yeah if they have enough grunt to turn a
    you could mimic big ship practice, diesel electric or in our case magnetic electric. Anybody good with numbers to see if it will work As to variable or controllable pitch props, take a look at this You Tube Clip, great model engineering. Ian

    Magnetic motors
    Hi Guys, This type of motor would be good if you could control the speed. There will be no need for a main battery for the model, you could also drive a motor
    to keep the receiver battery charged. https://youtu.be/wsWpkkCh_lI Maybe one day! Martin.

    Battery backup
    The web is full of low-battery detection circuits - including those with latchable switching to stop the circuit turning back off when the main battery recovers voltage as it is rested. See the link below.https://www.google.co.uk/search?client=opera&q=low-battery+detection+circuits&sourceid=opera&ie=UTF-8&oe=UTF-8 An alternative approach might be to detect, not the dropping of a voltage to some specific level, but the actual failure of the R/C signal at the servo due to low voltage. You can do this with a 555 easily enough and less than half a dozen components - this is often used to drive a sound
    to find a missing aircraft (just turn off the radio), or some other failsafe action. For instance http://www.circuitstoday.com/missing-pulse-detector-circuit-using-ne555 A latchable missing pulse detector coupled to a switch to add a single C NiMH battery to the main power (and an LED warning) would let you get the absolute maximum out of a battery and then boost the voltage sufficiently for a short home run. That is, if you want to run your batteries down to their limits and you are running on such a low voltage that the BEC is the first thing to go. You could also take pulses off the prop-shaft if you didn't mind the circuit switching in whenever the boat stopped.... ๐Ÿ˜Š Usually, a boat running slowly would be the best indication to come in and change batteries....

    Direction finder aerials /water pumps
    Have got some small geared motors spare and can work through my 6 volt reducer in use with the smoke
    . Switched in conjunction with my esc so it runs when the prop runs. Also the same switches to run pump for engine cooling.

    Direction finder aerials /water pumps
    Gents, Generally- Antennas for the relatively inexpensive commercial NAV/Weather radars generally rotate. The box often seen directly under the antenna contains the gearbox for this. Sometimes the whole thing is hidden in a fibre glass radome anyway ๐Ÿ˜‰ The more elaborate multi-function, fixed antenna (panels etc) radars are the domain of the military. But radar wasn't really the question anyway.๐Ÿ™„ Antennas for Radio Direction Finding (RDF) can be rotating loops / crossed loops (bit old hat now though) or fixed multi-element antennas whereby the receiver and display electronics sense the progress of the wavefront across the elements and show it (+/- 5ยฐ or so) on the screen. Usual RDF sets for trawlers and other commercial vessels operate in the VHF band, in particular for detection of VHF IMM Band distress calls. Can't be more specific without knowing what you are trying to depict Elsrickle. Attached is a link to a typical modern VHF/UHF SAR RDF unit, also showing the type of multi-element antenna used. If your model is of an older type vessel it may well have still had a crossed loop antenna. More input = more output!! APPEAL TO ALL SHIP MODELLERS:- At this juncture may I respectfully request that when asking for advice please provide all possible/available information on the model concerned! Type, Name, era (when built if known) of the original, equipment fit of the model and intentions of the modeller.๐Ÿ‘ Regarding 'water spurting' (๐Ÿ˜ฎ๐Ÿ˜Œ) This is the outlet of the engine /
    cooling water circuits. As far as I have seen ALL ships have them. You may not notice this on modern stealth warships - cos they 'pee' underwater ๐Ÿ™„ Cheers, Doug ๐Ÿ˜Ž

    Being Sociable.
    Hi Gary, My apologies for not seeing your post earlier, I don't log on very regularly, preferring to spend as much of my spare time in the work shop. I am interested in marine steam as well and currently I am building a model of Formidable, LT 100 from John Pottinger plans enlarged to 1:24th scale. I have built a double acting, twin cylinder oscillator, steam is to be supplied using a steam
    otherwise known as a mono-tube boiler. Control being done using a Taranis 9xd programmable radio, quite untested at this stage. I have added a couple of photo's. Cheers, Stephen.
