Ok here we go... forward light example: I took 1 wire from each led and wrapped a small piece of copper wire round them then soldered into one. Then did the same for the others. Then connected to a 9v battery connector using plastic connection block... My son had been doing electrical circuits at school and wanted to help me...
Hi Neil, Don't know how Graham wired his but the simplest is series for each lighting circuit; minimum wiring and only one current limiting resistor calculated to set the specified operating current for the LEDs used. In a parallel circuit the resistor value must be calculated for the sum of the operating currents of all the LEDs in the circuit. Required Resistance = (Voltage Source - LED Forward Voltage) / Max LED Current or R = (Vs-Vf) / Imax As an example, a particular LED has a 3.0 volt forward voltage (Vf) and a maximum current rating of 20mA. It is to be driven with a 5.0 volt source. Therefore, R = (5.0 - 3.0) / .020 or R = 2.0 / .020 or R = 100 Ohms If you do not know the LED specs, typically, a 80-100 ohm resistor will do just fine. All you 'never wanted to know' about LEDs in model boats (or any other model!) you can find here - http://www.laureanno.com/RC/LED-assembly.htm Cheers Doug 😎
Hi Neil, Well you wanted info!! 😉 I have a digital subscription to Model Boats and remembered seeing the article. I don't build yachts but can still admire the craftsmanship and techniques used. Some come in handy for other projects, e.g. winches. No idea about MYA classes, I'm not a yachter! Dave_M most likely knows. Happy over-making, cheers Doug 😎
Thanks to a fellow in Tasmania I got plans for sea commander no names please took a week for my print shop to make plans size 24''in length I wanted to build the model in a scale that is manageable & easy to transport to the pond . Used 1/4 inch ply for ribs & cut them on my Drumel saw that's about 30 years old , so old I can't find blades any more in Canada
yep that's the one I was looking at !!!! still undecided if it really work £18 but I wanted to see what you get again. So I could price single items up or just scratch build the easy bits and just but the white metal castings. Many thanks again all.
Hi Mick , Just wanted to check if the parcel arrived ,also posted out the drawings and build instructions so you should get these soon .Mark, if you read this Ricky cut yours in the wrong material (MDF) so will recut it in ply either today or at the start of next week depending on his work load. I gave the MDF one to a student for her grandpa.👍 Cheers Marky
Hi Chris I have used Iso Propyl Alcohol as a solvent for many years and also to clean electrical boards and contacts. You need the industrial strength 99.9% as the rubbing alcohol only has 70% IPA. It will thin most resins and evaporate leaving little residue, so will have little effect on what you are intending. It's freely available as HMCR are not concerned that it will be used in place of Alcohol, which carries duty. We as individuals cannot easily buy denatured alcohol in the UK and meths contains other additives which are unwanted for your purpose. Cheers Dave
Hi Dave, The original prop was about 42mm as was the 2-bladed replacement before I filed it down to approx. 38mm. The battery is a Ni-mh 7.2v 3700mAh 6-cell VP racing battery. As you can see from the photos I am getting a semi-planeing speed which is what I wanted as I think it looks "right" for this model. It is true that the boat is rather heavy but that is because I have left my father's old 1960's transistorised receiver in situ, partly out of sentimentality and partly because it seems to balance the boat nicely.

Doug I know what you mean about knowing which way the wind is blowing. One cold April day when I was 17 I had to strip to my undies to get to a 9 yr old who fell into Newsham Park model boating pond. Everyone else was standing shouting instructions to the poor lad. I ran round half the pool to get to him just as he had gone down for the third and last time.I had to pick him off the bottom. His heavy overcoat which bouyed him up at first had got logged and dragged him down.When I got him to the bank he was breathing ok but as I got out the wind hit me. Luckily it was just up to my Nuts so only a bit of my undies got wet . Y fronts.I got a letter of commendation from Shipwreck and Humane Society . And his mum put a thank you letter in the Echo as I hadn't wanted the publicity so didn't know who I was. But as you said you do know where the wind goes.😋👍😜
Hi Thanks Doug Yes I liked it too when i first saw it although it may have been in one of those patriotic war films we used to see so many of years ago. Could even have been a carry on . Memory doesn't stretch back that far. Some of the battery packs came with models from the estate of a deceased modeller .Got all his gear bar one model his daughter wanted to keep. A variation on Pou de Ciel.Trouble is I was struck down with my hips suddenly and have gone through all sorts of probs . Hopefully it won't be long now till I'm mobile again. Then I can get on with things. 👍
I presume you want to know how to attach the line, I drill through the center and put a 3" long cocktail stick through the hole and glue in place with epoxy. Then a piece of fine stiff wire formed into a U is bound and glued on the bottom of stick. Then painted in bright colours. Small flag can be put on the top if wanted. Attach a suitable length of fishing line to the wire loop and other end to the boat. I then use a PVA bag to coil the line in. This desolves in water.( available in fishing tackle shops). So if boat sinks bag desolves and releases line.
Got this boat about 3 weeks ago could not beleave the price i won it for £26.01 its 63 inchs long (5feet 3inchs)the guy that started to build it had passed away it had be in a damp shed for 3 or 4 years.The cabin top was half fitted and when i fitted it the cabin was twisted. All so the couriers had damage it around window frames,but i wanted to keep it as it was so repaired the damage and did not replace it.After lots of wet towels and wifes old micro wave a few swear words when i burnt myself i manage to untwist the cabin.A lot of you might not like the planking i have done but i wanted it to stand out.I used styrene over the repaired window frames so it would be easyer to paint them and to make them a little stronger.Cabin now planked a wood strip to fit between cabin top and deck to stop splashes getting into the hull.I have had 4 strokes so my brain works a little diffrent now and maths is one thing i have lost.If any one has a copy of fairey huntsman 31 1/6th scale to sell please let me know as it would help a great deal any spelling mistake i will say sorry for now here are so photos of where she is at now.I say she as i am going to call the boat LADY LUCY after the old boys daughter also going to put brass plate on with built by tom as he did build most of it and its a nice way to remember him
Hi, I am a new boy but I just wanted to let members know that I have a Billings Nordkap Trawler for sale. It is in excellent condition and full working order, ready to sail. It comes with Transmitter and Receiver, Built in On/Off switch, a rechargeable 6-Volt battery which can be charged in-situ with the charger supplied. It is 32ins in length, 8ins wide and 17ins high. It would need to be collected from my home in Kenilworth, Warwickshire. It is for sale today at £250.00, and all ready for the water !j. 12th September - It sold today. Thank you for your interest
