36" Thames River Police Launch by Robbob by robbob Fleet Admiral!   Posted: 10 days ago
After the successful build of the ‘Vintage Model Works’ RAF Crash Rescue Tender I was asked by Mike Cummings of VMW if I would undertake to build a prototype of their new model with the aim of checking the construction method and the assembly instructions for accuracy before the kit is put into production. The model is a ‘Thames River Police Launch’ and is based on the original design by Phil Smith for the Veron company, this was a very popular model kit in the late 50’s and 60’s and sold for the princely sum of 43 shillings and tuppence, approximately £2.15 in today’s money but an equivalent cost of £48.50 in 1960. This design has been updated to accommodate electric propulsion and radio control by Colin Smith, the son of the original designer and it has been re-scaled to be 36” in length where the original was 24” which gives much more scope for detailing and provides more ‘hiding room’ for the drive, control systems and all the associated wiring. The kit produced by VMW uses the same construction techniques as the original and the materials are a combination of balsa and plywood both of which a laser and CNC cut for precision. The ply and balsa materials supplied are of very high quality as one would expect from VMW and all the stripwood for the chines, rubbing strakes and deck detailing is included, even the dowel required for the mast is in the box, very comprehensive! The kit also includes white metal fittings such as the fairleads and stanchions, and the searchlight and horns. The glazing for the windows comes in the kit too. The instruction sheet supplied is in need of revision as it is largely taken directly from the original as written by Phil Smith and some of the terminology needs updating, for instance the ply bottom and side skins are referred to as ‘strakes’ but I understand that a re-write of the instructions is in hand along with an updated plan showing the best positioning for the motor, prop-shaft, battery, ESC, receiver, rudder and servo. During construction I have added a few additional pieces of ply or balsa as reinforcement or supports and substituted some balsa parts for ply where I thought a stronger material would be better. I also added some hatches to give access to the wiring at the bow and the rudder & servo at the stern but largely I have not gone ‘off plan’ to any extent. The pictures show the model in it’s present state (Nov 2018) and is ready for painting and finishing.

Vosper by Biscuit Sub-Lieutenant   Posted: 12 days ago
[Score: 10/10] 42" Vosper Single Propellor (3 Blade 50mm) Geared to a Os 40 fourstroke (3 Blade) - Comments: I always liked the sound of a fourstroke engine so I thought I would replace the brushless motor in this boat with an aircraft Os 40fs which I converted with a water cooling jacket that I turned up on my lathe. I also made a reverse gearbox with a clutch, the gearbox is operated by a servo and works well, I also fitted a water pump so could still cool the engine while ticking over stationary, boat has been weathered and is fitted with lights and a searchlight that swivels around operated by another servo, there is also a cooling fan above the engine just to help keep things cool.

Vosper by Biscuit Sub-Lieutenant   Posted: 13 days ago
Well this started off brushless but it had no soul or character, I bought an Os 40 fourstroke and converted it to be water cooled, I then made my own reverse gearbox and clutch assembly and fitted a water pump so the engine will keep cool while stationary. It has nav lights and a working searchlight that I can move while running.

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 2 months ago
Mornin' Pete (it is in Germany anyway!) I agree, there are lots of details and 'standard equipment' missing from the basic model. You can see the winch and Life Raft canister in one of the photos of the original I posted above. Re Mast wiring; don't fiddle about putting a divider in the mast. It'll just get in the way. Attached is a pic of my modified mast. I used a 0.5mm brass wire on the right-hand side for the earth return. Wire is better than rod cos it's flexible (can be pushed into the corner). I glued it in with gel Gluper Sue WHEN all connections were soldered and tested. The LEDs are standard domed lens types. I ground the tops flat and painted the tops with several coats of matt black until it was opaque. After testing I closed off the mast with some plasticard and fitted ladder rungs made of copper wire. I also added the missing antenna cables to the bottom of the VHF IMM antennas, 0.5mm brass wire. (Some time I'll also fit the missing GPS antenna and anemometer.) Then painted the mast matt black. I then turned my attention to the searchlight and red/green NAV lights. First I stripped the wheelhouse roof and painted it white as in the original. On my model it was grey🤔 Then I drilled out the searchlight to accept a 5mm Bright White LED. You won't have to do this cos you have a later version with lights, mine had none 😭 Then had to paint the searchlight with several coats of matt black. Otherwise it just glowed all round! Pics show construction stages and finished lighting effect. All wires inside the wheelhouse roof I super glued to the ceiling and ran them down inside the funnels (stacks to you guys across the pond!😉) ready for connection to a switch board in the hull. While I was at it I rubbed the false Southampton name off the cabin using a 1000 grit Tamiya sponge and am preparing inkjet printed decals with the correct Wyeforce name and logo. Have fun getting all lit up Pete,😁 Cheers, Doug 😎 PS Attached some pics showing the original 'Southampton' 😉 and making obvious what's missing on the model 🤔

Range Safety Launch? by trekil Seaman   Posted: 3 months ago
Hi NPJ . have just read your blogs re RSL. I spent twelve years in the RAF on Marine craft and was the coxswain of RSL 1662 the boats in the uk were painted black and overseas were painted white, they did`nt carry any fire monitors and no radar while i was in the RAF ( came out in1968)they did have the sweep searchlight. If you search for RAF boats you can see a picture of 1662 leaving the jetty in Londonderry. They were used officially for keeping the bombing ranges clear of all shipping when the ranges were being used but mostly used while i was in the RAF for ferrying personal about. 1662 was used for ferrying RAF aircrew to Naval ships anchored at Magiligan point and bringing Naval personal back to Londonderry to be taken to Ballykelly airbase where JASS ( joint anti submarine school) was joint meaning European and American ships and aircraft. I have the plans of the rsl and hope to build it over the winter months . the y were powered by two Rolls Royce C6FM diesel engines with teleflex controls and had a speed of 22 knots.Hope this gives you a little insight of the use 0f RSLs

Martin's Taycol Conversion Boards by RNinMunich Fleet Admiral!   Posted: 3 months ago
Howdy Ed, Yep, will do. Have taken some pics along the way. Mast lights and searchlight are working. Red/Green Nav lights fitted (had to spray the roof the right colour first - white not grey!) but not wired up yet. About to do that now. After that the two aft facing Towing lights and deck flood lights. Also discovered that there should be two deck lights P&S of the main cabin😉 Will need the miniscule chip LEDs for those - Now, where did I put my microscope🤓🤔 In fact while researching I found there's a whole list of 'bits' missing. Not least the Life Raft, which should be behind the wheelhouse!!😲 (In God we trust - But just in case we want a Life Raft 😁) Have also started drafting new decals with the correct owner's logo and fonts. The wiring is only a lash up at the moment to check that everything works. As soon as I'm happy, with resistors an' all, I'll fit some mini connectors. More soon, (in a different thread cos this will bore the pants off Martin. A NO Lights Man!) That reminds me of a banner I once saw above the RAF Controllers at the London Air Traffic Control Centre. "RAF controllers do it in the dark" 😲😉 The civil side was brightly lit, other side of the wall the RAF guys had minimal desk lighting only. Cheers, Doug 😎

Hi Rob, I wonder why the drawing does not show the loudhailer on the opposite side of the roof to the searchlight.🤔 Cheers, Peter

Sea Trials and mods. by robbob Fleet Admiral!   Posted: 3 months ago
It’s been a while since the boat had it’s maiden voyage on the lake at St. Albans and I’m pleased to report that it looks really good in the water and goes like stink if you open up the throttle. Sadly I still don’t have any decent video of the boat yet as I can’t film and drive the thing at the same time, but I do have some static wide shots from my GoPro. When I do the video I’ll ask a cameraman mate to do the honours, maybe I’ll put the GoPro on the bow and then the stern to get some low action shots…the storyboard is already building in my head!! These early runs were great as they showed up some minor problems that needed attending to. I found that it needed ballasting slightly as it was not sitting on the waterline evenly from side to side so I flattened out some old lead water pipe and cut it into small sections so that I could add ballast incrementally. I did this in the ‘domestic test tank’ and once I was happy the lead pieces were fixed in place inside the hull with some super strong double sided tape. The ESC needed a little programming adjustment because I had forgotten to set the low battery level point to ‘off’ as I am using NiMh batteries and not LiPo’s , that was the cause of the short initial run time on the first outing…..DOH !! The batteries are now held in place by Velcro straps on some bearers that I added, otherwise a battery change involved cutting cable ties and replacing them at the lakeside…not very practical. The volt/amp/watt meter is also now on a proper bracket so that the display is more readable. I have also changed the charging connection from the nasty Tamiya connector to a nice little panel mount XT 60 connector that HobbyKing sell, it comes with a handy blanking plug that I have drilled for a retaining cord. I have also finally got around to upgrading the firmware on my Turnigy i6 radio to the 10 channel version so that I can assign the lighting to the switches properly and have the rotation of the searchlight on one of the two rotary knobs. I can use the old 6 channel RX in the new boat….blog coming soon.

Not that I can see. Just a searchlight. @Robbob, What do you think?

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 4 months ago
Hi Pete, Yep, the colour of the LEDs can be determined by doping the diode chip with various elements. The early ones were either red or clear, so the colour was added in the epoxy dome around the chip. Cheap ones still are like that. Nowadays you can get LEDs that light different colours according to the voltage applied! For instance in those irritating shelf / vitrine light strings that rotate through a variety of colours all the time.😡 I have some that are red or green depending on which way round you apply the voltage! They are milky white when off. Useful for checking the operation and setup in the boat of brushed ESCs and motors, esp for multi-screw boats, and the output of switching circuits. Funny I always thought halogen lights were a hard white with a blue tint, like some car headlights. Cool on the Kelvin temp range. Yellow is more like the warm white light of a tungsten bulb to me. Yellow deck floodlights are more likely to be sodium lamps, like many street lamps. The measurements you sent me indicated that the switch on voltage (Vf) of the searchlight was 3V and all the others 2V. So I based my final calc on that. If any of your LEDs don't 'strike' with 150Ohm just reduce the resistor to 120 to give it a 'shove'😁 I don't expect that though. I have a box of 300 various LEDs and 1000 various resistors in front of me (and the mast from my Southampton tug😉) so will do some practical tests. Cheers, Doug 😎 BTW: I can strongly recommend that you buy a simple LED Tester, like one of these- https://www.ebay.com/bhp/led-tester I'll help you get the LEDs the right way round in your circuits and tell you how much current they need for a decent brightness, and at what voltage they will turn on! Only a few bucks and saves a lot of aggro. It'll also tell you what colour a 'clear or white' one will be when it turns on😊

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 4 months ago
Hi Pete, Hope the eyeballs are better 👍 Think I've now got the ultimate configuration 😊 (or the possible, tentative, subject to committee approval and board resolution, potential penultimate configuration 😲) See attached pdf. All new stuff is in red. Thinking is as follows, according to the mast diagram you sent me- L3; NAV & Towing in parallel 2 ccts; one for the port & stbd in the cabin roof, one for the white rear NAV & Towing, yellow, on the mast pointing aft. L4; 2 white deck working lights plus new LED for the cabin light - white or yellow/amber. Your choice. I might be inclined to go for yellow as bridge lighting tends to be not too bright so it doesn't impair the night vision of the watch. Could be why it was a bulb in the first place - softer light ? R2; Anchor light at mast top only. Makes no sense to combine with running (NAV) lights etc. R3; The three new white running lights on the mast pointing forward. L2 and R4 remain as they are for searchlight and horn. Now working on the corresponding wiring sketch. More tomorrow. Cheers, Doug 😎

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 4 months ago
Evenin' Pete, first instalment coming shortly in pdf format. A table, based on your excellent sketches of what you want to do, showing control element on the TX, function, number of LEDs in the cct or ccts, resistor(s) needed, current consumed, for various battery voltages. Example attached as jpg pic. Based on your measurements I am assuming that the searchlight is a 3V high brightness LED and all the others are 2V LEDs, and nominal current 20mA. This means that with a nominal 7.2V supply (Vs) for some circuits with 3 or 4 LEDs two parallel ccts will be needed. All will shortly be revealed 😉 I have optimised the resistors so that a) the LEDs don't fry when the batt is fully charged, 8V, b) that the LEDs can still turn on when the batt voltage dips to the 7.2V nominal. c) Only 2 or 3 values will be needed. Now have to convert my Excel file to pdf. Will follow this up with wiring suggestions, including the little Distribution Board with the resistors. I've tried to combine the lights you want logically considering how they would be used on the real ship. Stay tuned! Cheers, Doug 😎 BTW; the mods and resistors suggested in the table mean that the existing SMD resistors on the ccts board must be shorted / replaced with wire. Your wrapping wire (stripped of course!) will be ideal for this😉 Hope you have a small soldering bit!

Spektrum, new, useless... by RNinMunich Fleet Admiral!   Posted: 5 months ago
Hi Martin, First your last question😉 "What DO you do with a 3rd channel?" Example: 5 foot destroyer! 1 Throttle. 2 Rudder 3 Gun rotation, servo and pulleys 4 Torpedo tube rotation, servo and pulleys 5 Smoke switch, servo and microswitch (Smoke could be linked to the ESC to free this channel for the ASDIC pinger!) 6 Split into four functions (by misusing the gear down lever on my Graupner MC-10😉) for Whoop whoop, Fog horn, searchlights and signal lights, NAV lights. All switched via a home brew decoder / switch board and 5V relays! Alles klar? 😉 Re the DX5e; If I were you I'd let a (supposedly?) Spektum trained guy look at it first. With luck he'll have a service manual or at least a circuit diagram, which I don't 🤔 and should know the binding procedure backwards. I could only do some rudimentary tests without the circuit diagram, and make some educated guesses. I could at least try binding it with a variety of Rxs, including my Spektrun RXs which all work faultlessly with my DX6. Up to you, will PM my address anyway. I could at least check, with a simple RF meter, if the damn thing is transmitting at all! Just thought - if you're going to smash it anyway ........ 😉😁 Cheers, Doug 😎 PS: 4th attempt at the prop shaft for the cutter also failed 😡 She just does not want to get her bum wet!! Too long 'on the shelf' 🤔

Happy Hunter by liamduck Sub-Lieutenant   Posted: 5 months ago
[Score: 8/10] 44"/7300g Happy Hunter Twin Propellors (4 Blade 50mm) Direct Drive to a MFA Torpedo 800 (4 Blade) Powered by Lead Acid (12v) 7Amp/h Batteries Controlled Through Action P94 ESC - Comments: Found this kit on a well-known auction site and bought it for £100. It is the original Robbe kit and fittings included. There was no command module and so I have devised a way of having working anchors, tow, crane and warning beacon, bow thruster, nav lights and searchlight. It was a bit of a struggle to balance her properly and she needs quite a lot of ballast. A real handful, you might say but she looks really well on the pond.
