Hi Boaty, The Taycols have fascinated me as well, ever since I dug the Target out of the Sea Scout my Dad built in the early sixties. I blogged my renovation of that and the conversion to run with a modern RC system and presumably that, and the converter boards I built for Martin (Westquay), is what triggered Colin to ask me to have a look at his Supermarine. How could I resist!? 😉 The 'smell of something electrical' is the ozone gas caused by the prolific sparking of the Taycol metal to metal brush / commutator combination. The other source of Ozone is on the coast wherever there is a strong surf! I agree, a nostalgic smell, which unfortunately disappears when the converter board is attached to make it run with a standard brushed ESC. The diode bridge kills almost all the sparks. 'Almost' so the usual suppression capacitors are still recommended. 0.1µF across the brush terminals, 0.047µF from each terminal to the motor can, or frame in this case. Earth to prop shaft tube as well if possible. The motor may not disturb the on-board electronics of your own boat, if using 2.4Gig, but could still affect anyone nearby using 27 or 40Megs. The power density of spark transmitters (e.g. unsuppressed E-motors, peaks in the upper HF bands and diminishes to almost zilch in the UHF bands. I.e. approx 300 MHz upwards. Like me and other submariners for instance; 2.4Gig is useless for subs cos it don't go underwater. Cheers, Doug 😎 But here! BTW Boaty: where are the pics of your Avanti? Harbour posts without pics are pretty dead 🤔 Cheers, Doug 😎
No Doug, you have quite the wrong idea about me. I would love to get a club going and have done all I could to do so including meeting the one only geezer who offered to have a cuppa in the local caff. We parted with him saying he'd tell those members of a distant club he went to that had water problems and would call me. Guess what? You know the rest. THAT's why my attitude is **** '**. I've had it constantly from model boaters. Little enclaves of mates who will NOT countenance new members (model railways clubs too as it happens, more old farts). What else should I say faced with that attitude. No, I am NOT a tolerant or patient man, that's for sure. Patience is just an excuse for wasting time. I have no idea what apps are available for 'phone control. I don't even have one. Whilst my kids have made an excellent job generally of raising my Grandchildren, they don't seem to know either what to do about the latest fad for Playstation and 'phone. But one things for sure, none of them show the slightest interest in making or doing anything and are part of the first generation to be absolutely bloody useless. I just hope the three of my 5 grandchildren who have common sense will do something with that, but I know damned well it won't be keeping modelmaking going or any other endeavour that requires real skill and application. These matters are of concern in all the hobbies I have any interest in. Old boats (yes Woodies and why not?), old aircraft, old bikes and old cars. As long as WE live, eh? Well that ain't gonna be that much longer in any kind of fit state to go the pond on a regular basis with heavy models. So actually we WILL be witnessing the death of all those groups I mention above and many more. From the care home windows, unless we're lucky enough to cop our clogs before that living death happens. When you hear "Can't be arsed" from the mouths of, effectively, babes, you know the craft world is in trouble. And I mean craft, not gluing bits of cut card together with Prit sticks under the banner of that foul word "crafting". I really couldn't give a **** if I was the only person left in the world making woodies. I do it for me only these days in the absence of any clubs. But I don't have to pretend to like all the other stuff. In another place are people who not only do sail, but specifically model barge racing and good on 'em. I don't ask that they do all the other stuff. And as far as I can see they don't. My comments about the future are based on my observations and chats with established long term members of those hobbies who all agree the end really is nigh. All those balding, grey haired, pot bellied, probably bearded old geezers standing around with stoops from their long knackered backs, all wondering whether this time next year they'll still have their Honda Jazz or a mobility scooter. If that's how it's all going, so be it. As you say we won't be here to witness the real death. And the more exciting aspects of the model hobby? There was a programme on tonight about modelmakers flying re-runs of Battle of Britain air battles with similar sized models, laser guns, damage smoke, etc. 2 youngish blokes, the rest, including the German contingent, older guys. Oh and a Tranny and I don't mean a transmitter! In 10 years time that programme will not be makeable. BTW the Tranny was by far the best pilot. Cheers, Martin
Hi Colin, As discussed on the phone; 2V grid bias, 90V anode supply! In those days they had 90V dry batteries, they musta run it 'sumow'! 😁 Don't give up so easy! Nowadays how about a 24S LiPo? Or even Martin's 'big box' solution. http://www.batterysupports.com/lion-lipo-nbsp-88v-nbsp-24s-c... 24V chargers / balancers won't be cheap though🤔 2V is no sweat; 2V SLA, a la Glow Plug starter. How big is the boat an' how much weight can she carry? My first car radio was an ancient Echo valve job, with an inductive inverter bolted under the dash to produce the 90-100v for the bottles. Took me ages to find a way to mount it so it didn't make the whole dash hum like a swarm of bees😲 Later there was briefly a generation of 'low voltage' valves. Soon superseded by transistors from 1948 on. (And NO I'm not pre '48 vintage, well not quite!😉) Looking forward to your progress reports. Would really love to witness one of your displays. Please keep me posted about dates. All the best to you both, Cheers, Doug 😎 PS building a transmitter to match won't be easy. A TX on the right frequency is relatively easy, the tricky bit is the 'modulation' for the control functions! Hats off to your guy 'up the road' if he manages it! I'd really really love to see THAT!
Flying Osprey Tug Glasgow. Ready to sail. In good running order, Water tight. Working lights. Size is 36" long, 12" beam, 24" top of mast. Can run on Rotten Row Southport. May deliver by arrangment. £180 inc transmitter and charger. SOLD SOLD SOLD GONE GONE GONE Thanks Peter
Neither can I Martin! "The transmitter used two vacuum tubes wired as a multi-vibrator with a tank circuit to constrain emissions to somewhere near the 27 M/cs band (same as MHz, but that name came later). With not a crystal in sight, transmitter frequency drift and battery voltage drain was a problem, so careful tuning just prior to short flights was the order of the day." http://www.modelenginenews.org/cardfile/ed_radios.html#3 Cheers, Doug 😎
Doug: The glass paint is indeed a great idea. It’s an idea that I’ll consider seriously whenever a situation arises that’ll make using colored LEDs impractical, such as on my 1:350 SS Normandie kit, maybe? Finding the flat-topped LEDs made staying with your original design an easy choice. Regardless of when the job gets done, I can just imagine launching the tug late in the day, waiting until just before dusk, then switching the lights on with the transmitter’s function buttons until they’re all shining & reflecting in the water. It doesn’t get much better than that. Thanks, Pete
[Score: 9/10] 23" Richardson (to be renamed) Twin Propellors (3 Blade) Geared Powered by NiMH (7.2v) Batteries - Comments: LED navigation lighting will be added soon. RNinMunich (Doug) has been extremely generous with his time & talent with helping me with this project. With Doug's help all of the lights on the boat, including navigation, spotlight, aft deck lights & cabin interior, will all be controllable from the boat's existing 2.4gHz unmodified transmitter!
I've just bought a futaba 6L transmitter. The plan was/ is to use a v tail mixer to enable to use both shafts independent but connected to the rudder in ahead mode. I have two e s c's. Will the controller do the job please.
Purchased new in kit form, from Robbe. 1998. Specifications:- Overall length: 1380mm. Overall beam: 360 mm. Draught: 300 mm. Mast height: 1800 mm. Overall height: 2200 mm. Standard sail area: 80 square dm. Sail area with Genoa: 94 square dm. Total displacement: 12 kg. Ballast: 8 kg. Scale: 1:10 Control Robbe Futaba F14 Marine transmitter / receiver. Channel 1 - Rudder servo. Channel 2 - Spare. Channel 3 - Genoa sail servo. Genoa switch module - fitted between the stick potentiometer and the transmitter channel 3 Socket. (Reverses the Genoa sail servo for Port or Starboard tack.) Channel 4 - Main sail servo. Channel 5 - Auxiliary 3 position switch - up position. Channel 6 - Auxiliary 3 position switch - down position. Receiver channel 5 - Mono Memory relay module. To drive the Blister motor out, to raise the Genoa Sail Clew. Receiver channel 6 - Mono Memory relay module. To drive the Blister motor in, to tighten the Genoa Sail Clew. Recently recovered from the back of the shed, where it has been in hibernation. Now I am retired and have some free time, it is under a review and refurbishment. New paint on the deck and upper hull (above the waterline). Solid state relay modules added, to replace the micro switches, operated from a cam on a servo (replacing analogue channel 2 with on/off channels 5 and 6). Pictures show the sea trials after the 10 year hibination. The Genoa Module had failed in the carbon potentiometers. No replacement available, so found a local electronics repairers, who changed the potentiometers for £10.00. The carrying cradle was designed to hold the sails, and secure the yacht while rigging at the waters edge. Also acts as a dry dock, while working inside the hull. When the repaired module is fitted, and the Genoa sail is operational, I will post detailed video of the Genoa sail winch and Blister motor and their operation while sailing. Genoa Sail Pictures added.
Our posts crossed Ray............. Thanks for all that and I understand the transport issues. Gives me a good reason for doing away with the 'weak bits'. I am trying just to get the Tender under power so it can be used during the next two months, then back to the yacht may be. However someone has been kindly tidying my stuff up and now I cannot find even the transmitter! Can print out the stuff you provided though................. All the best. NPJ
I must have been sleepy (or something?), when I loaded the car with boats, spares, toolbox and it wasn't until I got to the lake that I found I had forgotten the transmitter! Don't worry Ed, worse things happen at sea.
Sort of cross between HobbyKing and Woolworths Martin! I just used their German site to buy selections of LEDs and resistors, thanks to a tip from Ed (figtree!) Cheers, Doug 😎 https://www.banggood.com/buy/uk.html?sbc=1 PS Stuff just arrived, only ordered on Satterday arternoon. Wasn't scheduled until Wednesday 😊
