Taycol Supemarine Resurrection by RNinMunich Fleet Admiral!   Posted: 4 days 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 😎

HMS Cadiz by landie Seaman   Posted: 5 days ago
My dad built this over a long period of time, starting in the '80s. The hull is fibreglass and the rest is scratch built from plastic card, balsa, ply, wire and anything else he could adapt. Although he installed the motors, props and rudders he never completed the RC installation or tested it. I inherited his boat models a few years ago and wanted to "finish the job", getting the model on the water. After installing the RC gear and batteries over the last few months, this weekend was the first sailing outside the bath at the Valley Gardens boating lake. Happy to report that it sailed really nicely, seems to be reasonably stable although I did restrict it to calmer times when the MTBs and faster boats weren't running ! HMS Cadiz was a battle class destroyer, laid down and launched during WW2 although she didn't receive her commission until 1946 so didn't see combat with the Royal Navy, serving with the home fleet. Due to the changeover in pennant numbering she was originally allocated R09 and later, when the admiralty decided to revert to the D for Destroyer pennant numbering she was assigned D79. To reflect this my model has D79 on the starboard side and R09 on the port side. She was sold to Pakistan in the late '50s, and renamed PNS Khaibar. She was sunk with the loss of nearly all hands in 1971 in the Indo-Pakistan war.

Zyx drives v shottel!!!! by green72west Petty Officer   Posted: 6 days ago
Thanks for replying RNinmunich. I know the Difference between schottel and voith prop. I pointed out in post i wanted to use In your words "z drives" on my model iO am attempting to build. I am new to this so give me a chance to learn without some negative remarks!!! OK. I will take your advice and will leave hull alone. I could do with advice from Members of installation of "z drives" in Bow of the hull. Thanks GREEN.

Elizabeth Park! by figtree7nts Fleet Admiral!   Posted: 13 days ago
Captain's Log: I just got back from the park! The wife and I go for a walk. Three time a day! We ended up at our local park! Of course I planed it, like that! I wanted to see if there was any weeds or algae. Guess I'm lucky. There wasn't any at all! Just about a dozen ducks that's all. Looks as if her Maiden Voyage. Will be in about two weeks! It takes a lot of planning. When your model weighs 15-16 lbs. And you live on a third floor with no elevator!😱😲😤😭 One way or another. Brooklyn's having a Maiden Voyage!

Now Coating and Matting by NPJ Fleet Admiral!   Posted: 14 days ago
On to Coating and Matting. (as well as sanding!) Now have at least finished all the stripping. Then did the ‘bright light in the hull bit’ to look for areas that needed patching. The major problem area was in the bow and that did not receive the light as it is a totally blanked off compartment. However, it was obvious from the outside anyway so, could I assume it was the only leak? Decided to put a fine matt over the whole hull, not deck, just to be sure of best chance of success. I can imagine what will be said here if it still leaks after all this! I had ordered some supplies ready for the next stage and drew up a plan view of the boat to help think through layout of electrics and other items. Made my usual mistakes about size. Some fittings purchased too small………However, never too large now that’s interesting. Some materials purchased too large. Now have a life’s worth of Resin……(when does it ‘go off’ by?) Also have a lounge floors worth of tissue matting! Also Sandpaper. Now there is a mine field. So now I know a bit more about that and which way the numbers work! When I forgot to put the mask on, I had some of the crispest 'bogies' in years.............. No images posted! On the plus side, although I never wanted to get into this stripping sanding, filling sanding, sealing sanding, matting sanding, painting sanding, painting, sanding bit……………. I now feel I started out with someone’s boat I had bought and now it has become “my boat” for real! I am at the stage now where I have put some filler in and applied the first coat of Eze-Kote from DeLuxe Materials To use Eze-kote read stuff from RNinMunich on this blog or the’ leaking boat’ thread. Washes out of the brushes very easily. There is such as this ..... Youtube link - watch?v=yP05qv3QtUk RNinMunich or Colin H. and the like have bits of extra comment and experience that is always very helpful. BTW, after that finer sanding before first coat, I did the dust down and vacuuming bit but it still felt a bit ‘chalky’ so I gave it a wipe with Methylated Spirits. Now I realise that has water in it, so if anything goes wrong it could be blamed on that................. Having left the first coat to dry I started to cut out the light matt to apply after the next sanding. The matting I have is called Glassfibre Surface Tissue EGlass from FibreGlass Direct. A part of Tricel Composites (NI) Limited. Available internationally in lengths from a metre upwards, it is quite fine in weave so we shall see what happens. I have left quite a wide margin at the moment but may reduce that when I have tried using it! This is another first for me so plenty of room for mistakes............... Will need to cover with the matt in stages as I cannot get around all the boat without changing its position. Going for the bottom of the vessel and stern board first as I figure they are going to be easier than some of the other bits. Then will leave that to cure before moving the boat. Really worried about the joins/overlaps and how well I will cope with those, not to mention the curved bit! Started to look at electrics and layout for a bit of a change. I will post again when I have had the first battles with the matting! TTFN. NPJ

Launch ELAINE, by onetenor Fleet Admiral!   Posted: 15 days ago
And what a capacitor. Big enough to have come from a washing machine of that period. Maybe it did. The whole thing looks like a lashup. Used whatever would work.I had loads of old valves but noone wanted them so dumped them. Some of them were More modern ones to replace the DCC90 but 1/3 or less the size. Those relays look like the old G.P.O. type. We got them from a Gov't surplus shop for buttons. Those were the days. Sometimes we added in an R.A.F r/f amplifier without the case. It increased the range but don't ask me now how we wired them in. There were 4 connection points on the casing which accepted a multi-plug connector secured by a threaded ring. Nice bit of kit til we got our hands on them.😁

Launch ELAINE, by RNinMunich Fleet Admiral!   Posted: 16 days ago
Agree on the vintage value (same applies to your Supermarine actually!) I thought you wanted to try and get it all working. I see two more bottles in that perspex box. What are those? I'm beginning to wonder if that's the RX and the chunk with the DCC90 is the TX. The DCC90 bottle could produce 2W RF in the HF band. So 27Megs would be in for example. Cheers, Doug 😎

Still Stripping......With Care! by RNinMunich Fleet Admiral!   Posted: 18 days ago
Evenin' Neville, I told you you'd get the hang of it pretty quick. (It was either that or you'd burn the house down😲)😁 Seriously; I'm proud of you👍 You had the guts to give it a go and you're learning fast 👍 Hat off Sir! A few observations; (Colin might also have some at this point, had a very nice chat with him on the phone this afternoon - but that's another Encyclopedia Britannica!) #1 If the paint scraps are smoking the gun is too hot or too close, or moving too slow. Wind it down to 350 and see how that goes. Back up to ~400 if seems necessary. #2 Bow cracks; I see a bodge up there where someone couldn't bend the skin properly or, benefit of the doubt (In dubio pro reo!), maybe it was collision damage. Whatever; filler in a thin crack will always vibrate out again sometime😡 Try to get at the inside and seal it with two layers of fibreglass tissue well soaked in resin, EzeKote is what I used. Wait about 10 minutes before applying second layer. Then it should bond well with the first. When that has set (ca 20 - 30 minutes) then you can apply some fine filler from the outside. When set sand smooth and seal the whole hull outside with two layers of FG tissue. Sand smooth and if any bare wood appears apply wood sealer or EzeKote thinned with 10% warm water. Don't overdo the water or it takes yonks to dry and set - Yes, it happened to me🤔 Then continue with priming / finishing as described above; or look in my Sea Scout 'Jessica' blog for the fine details. The beauty of using EzeKote for all this is that you can get a whole hull done inside and out in one day and no mixing ratios to cock up😊👍 If it's any consolation to you; when I did all this on my fish cutter and PTB loads of filler went soft and fell out as well, and the 'goo' holding the prop shafts in my PTB as well. No sweat as I wanted to realign the shafts anyway! TIP: I removed all shafts rudders and any other protrusions in the way so there were no 'twiddly' bits left to make things awkward. Leaving the odd patch of sanded paint which is still firmly fixed to the wood is OK; as long as you can't feel a 'bump' with your finger tips and you are going to seal it with resin and primer anyway. Then it can't react with the new paint. Here endeth the 3039th epistle from Admiral Doug. Will all dissenters, contradictors and other lobbyists and Trump lawyers please queue up at the Spanish Inquisition Office next door. Take a number, we'll grill you in turn 😁😁 How do you like your stake? Cheers All, Happy building and renovating, Doug 😎 Now back to me fish cutter gearbox, mechanical gubbinses are not really my strength🤔 HAMMER, have you got a minute please!? (Viewing / reading tip; click on the thread title, then you can read the the structured version in paragraphs as I wrote it 😉)

Modav Huntsman 31 by RNinMunich Fleet Admiral!   Posted: 20 days ago
Hi William, S, X35 !? No idea😲 I assume they are terms from the racing world which I have no particular interest in. My intention wasn't to make her into an offshore racer. As it is she's well over scale speed, but fun to run, and that's what counts ain' it? 😉 Gives a good long run time, 1 hour plus, using a Propdrive 2830 BL and a 3S 4Ah battery. All up weight 1974gm. LoA 24", beam 8.5". My prop is simply a 35mm ca 14 pitch from Raboesch. Actually wanted the one with a blunter hub but they weren't available when I wanted it. The pointed hub variant is actually more like as fitted to larger naval units in WW2. Sorry🤔 Cheers, Doug 😎

Range Safety Launch? by RNinMunich Fleet Admiral!   Posted: 20 days ago
Hi Neville, Thought you wanted to renovate the original Range Safety Launch design? I don't see any structural changes from that design. That's why it was so easy to identify. If you want to add fantasy bits and fittings that's entirely up to you, but in that case the number, decals and even the colour can be fantasy too! How about sky-blue pink with purple spots? 😲 Your boat - your choice. Doug

Bit of a problem............. by NPJ Fleet Admiral!   Posted: 24 days ago
Well if you have read the “Leaking Boat” thread you will know that my cunning plan to fix the leak failed………….. Even after drilling holes in the boat (?!?!), pouring in sealer and persuading my ‘assistant’ (I think I am married to her, but it was a long time ago now to be sure) to shake the boat as you would a cocktail shaker to distribute the fluid over the insides (not seen her move like that in thirty years)……………………..Did not do the trick. Yes I know you told me! I am now not in a place I wanted to be. No sailing for it this season, facing the prospect of a lot of dust and over-spray and trying to apply skills I do not have. I am at the edge of my” River of Styx”. The images show I have reluctantly collected together items I have for stripping paint. The large wire brush I have in my other hand! So I have had a bit of a go at the ‘red stuff’. Looks like a large area to tackle and then I went to investigate that ‘funny bit’ on the side of the bow. Well bits of filler flew off in all directions and exposed this crack which I hope you can see to the right of the metal rule. Could this be the source of the leak? Well it is two compartments away from where the water collects. On the other hand someone mentioned water passing along the ‘layers?......... Am I really going to need to strip all the paintwork down to the wood or is there something else I could look for as a clue? Most of September I will not be able to function much so I will have a good go whilst I can. It really does seem to suggest I have “bought a pup”. All the best. NPJ
