Smoke generator by jbkiwi Commander   Posted: 16 days ago
Have just made a prototype of a fan forced smoker which seems to be working well (despite breaking the heater coil by moving it while hot, - had it apart, broke wire, screw and washer repair, not quite as hot) I bought a couple of Heng Long smokers (for R/C tanks or cars) to play with, for $10 NZ each(or 5.3 Euros to you Northerners give or take a yen) from Bangood and just bought another from Ebay. There seem to be 2 different models, as one has a long coil with a lamp wick draped over it, which is sitting in the oil reservoir, the other has a small coil inside a piece of heat resistant woven tubing (as you might find insulating toaster/heater wiring etc) which acts as a wick and that also sits in cotton wool in the reservoir, (this seems to be the better of the two) Tip - don't fill the tank right up, only enough to soak the cotton, element should be just out of the oil. The wick loads the element. The better model seems to have a black top to the tank (also maybe either brown or black tank) and the other has a brown top and dirty brown tank. As with most of this stuff you won't know till you get it what it's going to be. What I did was remove the tank and cut off the pump tube just in front of the screw lugs (see black line in photo) then fitted the tank, and a 40x40x10 5v ESC fan (voltage controlled by a UBEC set to 5v on the jumpers) into a plastic electronics utility box from Jaycar (our local electronics and hobby store). I made up a double JST lead for the 2s 1800Mah Lipo and fired it up (using baby oil). It's pretty much silent and smokes well once it gets warmed up, ( starts smoking in about 5 seconds) You could control it (on/off volume) by either a remote on/off switch or perhaps a small cheap 10A brushed ESC. I would leave the fan running and control the element to avoid burning the element. The original pump tank inlet hole seems ok as is (approx 1.5mm) but you could enlarge it very slightly to get a better flow if you could find a better oil. At the electronics store they have proper smoke machine oil for $20 NZ per litre so I may have a look at that. The reason I went for the fan idea was that I found in std pump form, if I immersed a tube from the tank in water, it sucked water back into the tank. I was hoping it would pump smoke out of my HSL exhausts at water level alongside the cooling water but it would need a very light non return valve to do this. The fan seems to pump the smoke through 2mm ID silicone tube ok, so tubing of similar ID to the OD of the tank outlets should work well. These pumps in original form work pretty well for the price, and are cheap enough to keep a few for spare elements, the only thing is they are a bit noisy but in an 'engine sounding' way, (might add to the effect on a tug or work-boat though) What you have left after this mod is a very handy little geared motor with an eccentric output wheel which could be used for winches, radar and whirly bits of any description (see pic of motor leftover and original) To avoid burnout, these should be run on no more than a 2s (around 7.5v-(suggest 8v max with fan running) The other tank is going to work a lot better than this one but I'm not making a tug, just want a bit of exhaust smoke on start-up etc to go with the 2 sound units. Very cheap to make (around $25 NZ with pump, box, fan and UBEC all through Ebay, Aliexpress and Bangood (and local electronics store) If you wanted to run an ESC to control the smoke and you have no channels left to control it proportionally, you can always try using a second receiver bound to your TX, (if your TX will allow it,) power it and a brushed ESC (wired to the element) as normal and use the throttle channel to plug in your smoke control. This should work if you want more smoke as you accelerate or if you are using only 1 stick on a 2 stick TX you could use your 'elevator' stick pushed up (or a toggle switch if available) to start/stop the smoke (through the brushed ESC setup) . This setup weighs 100g (10g more than std) The quest for lots of smoke continues Will try to upload vid later and update progress.

just need cable (wire)... by Westquay Fleet Admiral!   Posted: 3 months ago
No, not dioramas, Doug. Dioramas use forced (false?) perspective and therefore must be viewed from one point. I made a diorama of Shelseley Walsh hillclimb to show slot car models. It was quite effective. This is all new for me and I am gathering engine models (I hope) from various hot rod sources. It will save me time on building these. I have a Merlin coming from Holland and a few others from contacts. First model in this series will be Hornet II, the wonderful gar Wood Speedster which had an all aluminium deck and fin added and its Packard replaced by a Rolls-Royce Meteor, which was just a Merlin sans blower. Interestingly, the Rover Meteorite was a V8 version of the meteor and fitted in pairs in the Crash Tender. Martin

Landing Ship Tanks (WW2) by RNinMunich Fleet Admiral!   Posted: 3 months ago
Hi Nerys, I think that was only scratching the surface. I found that lot in about 10 to 15 minutes. But then I've been used to trawling the WWW for specific info for as long as it's been possible. Gave me the 'Edge' I needed in my job. Don't want these skills to rust in retirement, and I never could resist a challenge anyway. 😉 Plus I was moved by your story and found it worth following up. If I can help again please let me know. Know just what you mean about too many projects 🤔 My Danish fish cutter restoration and conversion from static to RC has got bogged down until I solve the problem of getting the drive right down next to the keel, my PTB restoration and conversion to Kennedy's PT109 is shelved for the duration, re-shafting / re-propping Graf Spee and HMS Belfast, upgrading my Southampton tug are gathering dust🤔 Materials gathered for 1/350 Plastic Magic conversions of KGV (thanks Colin) and PoW battleships, HMS Hood, HMS Ark Royal, T45 Daring class (witnessed the building of the lead ship! Stitching the modules together was fascinating😊), USS Enterprise CVN65, RMS Titanic, etc etc!!! kits for a 1/96 HMS Manxman and a 1/100 Akula 2 submarine are lurking in the cellar as well. Not to mention the 1/24 De Havilland Mosquito as a memorial to my Dad. Whichever ship you decide to do for your Pa if I can help in any way I'd be very happy to. Maybe you can decipher from his personal records which ship was closest to his sailor's heart!? I'd love and be honoured to be able to see some of your Dad's drawings and cartoons. Bon chance with your current projects, All the best, Doug 😎

Brushless motors (again) by Haverlock Fleet Admiral!   Posted: 3 months ago
depending upon the type of motor cooling it can be a problem. Most brushless motors are out runners so the case rotates! In runners are usually for higher speed applications (or driving a gearbox). If you have an idea as to the size of IC engine the boat was intended to have then this list may be a help .049 or .051 = 100 watts 0.10 = 200 watts 0.15 = 300 watts 0.25 = 500 watts 0.32 = 640 watts 0.40 = 800 watts 0.45 = 900 watts 0.51 = 1020 watts 0.61 = 1220 watts 0.75 = 1500 watts 0.91 = 1820 watts Since Watts are Volts * Amps ( I know this is not accurate for a reactive load like an electric motor but its a rule of thumb) This gives you a ball park next point is the KV ( revs per volt) of a motor. The higher the KV the smaller the prop. Finally buy a Watt meter they are not expensive and give you a chance to " fine tune" a setup. https://www.ebay.co.uk/itm/FT08-RC-150A-Hight-Precision-Watt... Car ESCs ( usually) have a reverse function while the airplane versions do not. They are generally cheaper than boat specific ESCs.

Darby One Design hydro... by boaty Admiral   Posted: 4 months ago
Westquay- Where did you get that hull. It looks great. I also have a spare brushless plus esc from a recently deceased surface drive hydro and I do prefer the submerged drive like yours. I have been searching second hand shops, the local flea market and car boot sales but found nothing. Boaty😊

Nomenclature... by onetenor Fleet Admiral!   Posted: 4 months ago
Ha Ha i got no credit for some things I came up with either Trouble is I can only remember the word FANTABULOUS which I invented by accident Fantastic and fabulous ame to mind together as I was talking and the hybrid word came out.🤓🤓 Re the BECS I know that but I couldn't explain it like you and was also asking what I thought Martin wanted to know. Floating arrays? Didn't TESLA do something similar during the RC boat . trials? Or was that actually the vessel itself? In one of my bigger boats I used FOUR ex GPO L/A cells which was enough with it's Ex forces motors to put a bone in the boat's teeth as the say. The boat ? RMV Mauritania 5 feet long but very light for it's size hence the need for the accumulator cells Balsa frames and sides with ceiling tile superstructure with balsa bracing. Free running so it was always heeling and with the bone creaming at the forefoot was very impressive. Destroyed by a guy collapsing on it. He'd only fainted but me pore owl gerl was just chips and snowflakes from one end to the other. Nothing to repair as there was nowt left to repair🤐 I kept one cell for starting glow motors and sold the rest at a good profit. Incidentally the motors were that good that when everyone found out where to get them They were sold out in 2 days with no more available anywhere Don't know what they were out of but from the overspray on them ( cockpit green but the Yank version -- we thought) we believed they were from planes. Very solid with 9 segment rotor . Totally enclosed. Airtight? presumably to prevent arcing igniting fumes. The rotorsegments? We found out when one didn't run so we stripped it and found them shining at us. Lovely tight windings. Thick with shellac/varnish. The problem? A stuck brush caused by a tight pivot Drop of 3 in one oil and a very light smear of grease cured it. The carbons were replaceable if you could make or find some. I found a firm in Formby that made and sold brushes for anything. I fixed son's Fiat automatic thenks to them. It had a magnetic clutch and the brushes were so worn we didn't know what the shape should be. Turned out to be about 2 inches long rectangles plain and simple. LOL. Wish I could find some of those lovely engineered motors now.😤👍

Taycol Supemarine Resurrection by RNinMunich Fleet Admiral!   Posted: 4 months ago
Mornin' John, agree re chromite, but still don't know what chroDite is! I only personally own the one Taycol Target. I got into this whole Taycol business while I was renovating Dad's old Sea Scout last year and decided I wanted a bit more Oomph so upgraded it to a 1000kV brushless, which gives goods results on a 3S LiPo. See the vids I've posted of the the 'Sea trials' (Lake Trials!?). So I decided to use the Target in the ancient Billing Boats Danish fish cutter I'm restoring and converting from static to RC. Figured the Target would cope OK with the plodding pace of a fish cutter😉 BUT, I wanted it to be reversible without cumbersome external switches or relays as recommended by Taycol / Keil Kraft in those days. After surfing around a bit a found a website where others had tackled the same problem. Looked at their solutions and refined them slightly. All I do is rectify the pulsed (square wave) signal from the ESC with a bridge rectifier (4 hi-current diodes in a bridge form in one package), apply the + and - outputs from the rectifier to the field coil so that it produces a constant magnetic field just like the permanent magnet of a canned motor. The two alternating (pulsed) outputs of the ESC are applied to the AC (~) inputs of the rectifier, which go + / - or - / + according to the command from the TX, I apply to the brush terminals just like a normal brushed motor setup. The output of the ESC is a train of either positive of negative going DC pulses. Pic 2 the positive train on the scope. Pic 3 the negative train. The larger and wider the pulse the higher and longer the voltage is applied and the faster the motor spins. So called Pulse Width Modulation (PWM). The gaps between the pulses are smoothed out by the inertia (flywheel effect) of the motor, and anything hanging on it - like a prop and a few million gallons of wet stuff 😁 Hey presto, a field coil motor that runs forwards or backwards on command 😊 Main thing is simply to separate the field coil from the armature coil (i.e. brush gear) so you can control each one independently. No rocket science but highly satisfying when it all comes together and works on the pond. OK, I'll look up Mr Lynch, wasn't he the Sarge in Z Cars 😁😁😁 Cheers, Doug 😎

Restore An American Nirvana Yacht by CB90 Fleet Admiral!   Posted: 5 months ago
I have by luck, not judgement acquired a second hand 'Nirvana' Yacht, it is a sloop rigged craft that was only sold in America and retailed between $250 and $350 according to the revision version and the year brought. This was a bit of a surprise to me as I only paid £10 for it. The Nirvana RC Sailboat was first produced by Megatech in 2002. and is 32in long and the hull& deck are ABS plastic. The quality of the boat is unmatched in the price range, with such features as a lead keel ballast, superior polyester sails that won't mildew, stretch or tear, and fittings that make the boat a dream to sail. The mast and booms are made of carbon reinforced composite that is light and very strong. The Boat hull is in sound condition just a few scratches, there is a hairline crack in the mast area, no radio gear at all. and sails are usable but really need replacing.

Tony O by Westquay Fleet Admiral!   Posted: 5 months ago
That might have been the case before the mobile phone/mini computer boom, Colin, but now they don't learn anything at school, there are no clubs at school and all they want is 'phone games/youtubes of other nerds playing games better than them (yes really!!). They simply cannot see any pleasure or fulfillment in making something and let's face it, apart from racing yachts and very fast raceboats, model boat operation will bore the best of us after 5 minutes! Going round and round with a coaster is limited to say the least. I get my pleasure from making them and almost none from playing with them. Try offering that as an argument to a kid who loves Fortnight or Minecraft. You haven't a chance! Model aircraft or car racing will always take them if there's a hint of interest as those are more exciting, if expensive. Martin

Brass bashin' Chris Craft deck fittings... by Westquay Fleet Admiral!   Posted: 5 months ago
I was just searching for a model car pattern I made months ago for some mods and I found all the lovely etchings I'd done years ago, pre computer, for Riva and Chris-Craft models. These two pics show two brass patterns for the Riva vents and two of the white metal cast vents, one polished about 20 years ago, one done just now, to show that a well burnished casting will stay looking chrome even without lacquer. Then the two Chris Craft tread plates I had the great, good forethought to draw when I found I had a bit of space on the Riva fret. They are perfect, as are the Chris-Craft side flashes and all the Riva badges, even though they were done from hand drawn artwork, proving that Vector images are NOT essential as the pootah people will tell you. I shall mount these two on the typically wedge shaped base and have them cast. I also found a FUEL engraved cap cover which will go on my Chris-Craft filler. It happens to be bang on size wise! I'm cock ahoop! I knew I had these, but had no idea where to start looking. Thanks Mel for getting me started on the search for your Tecno F2 car, but sorry, couldn't find that devil. I have made some more Vincent bits, been to son's to play on his new steering wheel and pedals racing game ( I managed a whole lap of the proper Silverstone in a Lotus 25!) and dined out with the lady wife. What a great day. Martin

Brass bashin' Chris Craft deck fittings... by RNinMunich Fleet Admiral!   Posted: 5 months ago
Thanks Martin, I'll look out for that👍 Yeah, the Lightning is cool, I had the 1/72 version back then. I recently bought the 1/24th kit of the Mosquito, another cool kite! It's a MONSTER and I haven't had the guts to start it yet😉 I recently found on the Krick site some chrome "Racing Paint for Polycarbonate Body's" made by Ghiant Aerosols in Belgium, branded 'RC Car'. Comes in two 150ml cans; chrome spray and a lacquer / fixer. Haven't tried it yet, will report when I have. Cheers, Doug

Mahogany in Scale by RNinMunich Fleet Admiral!   Posted: 5 months ago
Hi John, No I didn't know there was a premium on ED stuff! Will have to start touring the Flohmärkte here (Flea Markets - have never heard of a 'Kofferraum Sale (Boot Sale😉) here. Dimly remember drooling over ED engine ads, way out of my range back then🤔 Didn't know they did RC kit til it popped up here. Sorry to dash your hopes but Unfortunately I only have the info and not the stuff itself😭 Here are the links http://www.modelenginenews.org/cardfile/ed_radios.html http://www.modelenginenews.org/cardfile/ed_radios.html#3 Happy browsing / reminiscing 👍 Cheers, Doug😎

Mahogany in Scale by Westquay Fleet Admiral!   Posted: 5 months ago
Doug, I don't generally "do" foreign and Pete certainly wouldn't. As you say, most are model railway or strictly stick and string model ships. What we wanted to do was a general model hobby museum with a bias toward the RC hobbies. Ain't none of them. History of RC, RC cars, boats and aircraft. Materials, tools, etc. Mags and books, that kind of thing. Martin

Old Futaba servo wiring... by RNinMunich Fleet Admiral!   Posted: 5 months ago
Mornin John Re detector circuit: It's not very complicated, only 3 or 4 actual components. The clues are good RF diode and a very sensitive meter! I just bought a couple of 300microamp full scale meters. Will do a little blog when I've tidied it up and boxed it. Re Heli: can you post or mail me pics of the TX, RX and ESC please. Brushed or Brushless motors? Given manufacturer / model numbers I might be able to figure out what the pissibolities are. No promises though 😉 Sounds to me like the TX stick is set up for forwards / backwards like a normal car or boat set up. I.e. for 0 to full speed in either direction is only half the stick travel. For aircraft 0 is full down, giving you the full stick travel for the speed range. The ESC probably needs to be 're-educated' and the TX throttle stick re-programmed, IF at all possible with the TX you got with the Heli. Re " P.S. Signals come from where Doug?" - Don't understand the question John ?? Cheers, Doug 😎
