    36'' Thames River Police Launch by Robbob
    After the successful build of the โ€˜Vintage Model Worksโ€™ 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 โ€˜Thames River Police Launchโ€™ and is based on the original design by Phil Smith for the Veron company, this was a very popular model kit in the late 50โ€™s and 60โ€™s and sold for the princely sum of 43 shillings and tuppence, approximately ยฃ2.15 in todayโ€™s money but an equivalent cost of ยฃ48.50 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 36โ€ in length where the original was 24โ€ which gives much more scope for detailing and provides more โ€˜hiding roomโ€™ 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 โ€˜strakesโ€™ 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 โ€˜off planโ€™ to any extent. The pictures show the model in itโ€™s present state (Nov 2018) and is ready for painting and finishing.

    Motor reversing
    Hi All potential submariners! Please consider this before you happily launch your latest creation! You're down at the lake on a nice warm sunny day for a bit of 'messing about in boats'. So far so good. BUT ... before you launch your sub into the deep consider that the water temperature will be considerably less than the air temperature. So what? you might say. This what! To help keep the wet stuff out of the sub and away from your sensitive electronics you need a little over-pressure within the pressure hull (WTC), to keep it WT! Outside in the warm air this will occur naturally. BUT .. as soon as you dunk your sub in the cool wet the air in the hull will also start to cool and reduce the pressure within the hull. This is often enough to create an 'under-pressure' within the hull which can cause ingress of water by literally sucking it in through the drive shaft and control rod glands. Glug glug glug glug๐Ÿ˜ญ๐Ÿ˜ญ Time to wish you'd worn your swimming trunks and brought some goggles with you! Solution? 1 Acclimatise your boat on the surface before you sail away and start diving; i.e. let the water cool the hull and contained air before final sealing of the pressure hull and sailing off. 2 Fit a cycle tyre valve and take a cycle pump with you so you can pressurise the hull slightly before sailing. Don't overdo it, one or two pumps should do, or you might blow the sealing glands from the inside ๐Ÿ˜ฎ๐Ÿ˜ญ 3 A rubber (or similar material) membrane fixed into the pressure hull is a useful indicator of over or under pressure within the hull (WTC). 4 Fit a Pressure switch and a Fail-safe device which will automatically surface the boat on loss of
    radio
    signal (some RXs can be programmed to do this; i.e. all servos and ESCs go to programmed settings) or on exceeding a preset depth; e.g. 1 metre. Happy sailing / diving / surfacing๐Ÿคž. Cheers, Doug ๐Ÿ˜Ž

    Hi John, Don't know quite what you mean by SMS 'Plan' but I can assure you (as a former programmer of the first automatic cellular
    radio
    test systems) that there is no way that SMS (= Short Message Service) could have the capacity for video streaming, or even audio for that matter. As the name suggests! "Trouble is, here (don't know how it works there) is that all internet is on some sort of usage plan" True, if you insist on using 'Dumbphones'. I use almost exclusively a PC/DSL connection and the only restriction I have is how much I can leave / archive in my Mail account which is stored on the provider server, 1GB max currently. Could buy some more, but what for? What I do on the Web is irrelevant. So all I need to do is occasionally clean out my Mailbox; deleted, sent, received etc. What I want to preserve I transfer to a hard drive, either as eml or pdf.. BTW: I wouldn't touch What's App with a 20 foot barge pole, or Facebook, Twitter and all the others for that matter. Given their misuse of personal data as well as all the hacker attacks they have suffered it simply confirms the impression I got while involved in the early days of the net and especially the various cellular systems. I also did some programming on UK Type Approval test systems and could recognise the expansion possibilities of the cellular
    radio
    systems; all the large data blocks labelled 'Reserved for future functions' and filled with zeroes! I had to first analyse the data exchange between mobile and cell site to then devise a suitable test protocol. With the increase in usable bandwidth this 'availability' has since expanded considerably, not always for the benefit of the user - ever more for the provider! This site is the only 'social site' I'm on, I trust Stephen (Fireboat) far more than Mr Sugarmountain and Co. Regarding some sort of 'Group chat', great idea by the way; perhaps a VPN? Maybe Ed (Figtree) could help us with setting up something like that? Cheers, Doug ๐Ÿ˜Ž

    Sounds a bit like me Martin except I'm fortunate to be able to drive mine around. Great shame you can't get your fine creations out to a lake to see them in action.

    Batteries in a DX5e
    Hi Doug, I was meaning more here in NZ, as I know you have some nice shops in the UK and Germany etc ( I have bought quite a bit from Cornwall Model Boats who give really good service) and a few years ago was buying IC engines and parts from Just Engines in Shaftsbury who were a great bunch with spot on service and advice. A list of good shops would be great Doug as if you are not in the country you quite often don't get to know good local shops. When I was working on Norfolk Island (SP) in the 70s there was a shop called the 'Mini Golf shop' owned by a lady named Agnes who was incredibly knowledgeable on all aspects of modeling ( it's where I bought all my models, motors and

The shop was tiny (about the size of a double garage and was packed to the roof with model stuff from all around the world,- a real modelers paradise and it was known worldwide . Sadly it has been gone for many years as the tax system changed due to Australian interference, (they have now taken over completely) and is now just Lego and other crap (although at one time they sold more Lego than any shop in the world from the new -1980s shop) . I doubt whether there would be many shops in the world as exciting to enter as that old one these days.

Since the first posting testing has shown the single "C" cell didn't have enough power to turn the prop while in the water. Experiments with other batteries has shown a combination of two 3.7v Li-po batteries in parallel should give up to one hour run time.

You can get a set for less than ยฃ50 - I have seen them for less than ยฃ20! But get one with more than 2 channels if you want to do extra light switching. The hull is a displacement one - I suggest a standard 7.2v NiMh battery pack (though I don't know your motor voltage?). Do you have a charger?

    Yorkshireman refit- rear deck
    No turning back now I thought this was going to be straight forward. I've decided to put the main bridge superstructure to one side of the work bench and forget it, for now. In the past I found its easy to try to do to much, you get bogged down,disheartened and loose interest. So the next job now the decks are off was to check the rudders operation. It did seem a bit vague,the boat came with a full set of working
    radio
    gear. 4x6volt batteries in banks of 2 that took a charge well. A steering servo and 2x decaperm geared 6v motors turning in opposite directions with handed 4 bladed screws. The rudder cranks were white metal that didn't grip the rudder shafts tight enough, hence the vagueness, 1 motor was loose on the mountings, the other had a cracked gear box cover. Is it me, this scenario seems so reminiscent of so many good looking cars and bikes I've bought over the last 40 years, only to find within a couple of weeks you've got "sucker" written across your forehead, and a lame dog on your hands. These to me are the type of challenge I like. There the only ones I know come to think of it. New kits are for pussies? Jokingly. Anyway if someone in the past has taken all that time and effort to turn a silk purse into a pigs ear, I look at it as a challenge to turn it back into its former glory. None of the hatch tops were square especially the covers for the rudder cranks, and as can be seen in the accompanying photos the deck holes weren't raised to stop water ingress. I re cut the holes to help fit new cranks and fitted 10mm up stands, made new sheet hatch covers then refitted the original hinges and handles. Also while cleaning the loose paint layers off the outer stern bulwark, I uncovered the original name of the boat. It was originally a "Yorkshireman" hence my goal to turn a Irishman into a Yorkshireman. Apparently after a bit of reading up they were sister ships in real time and were built not 20miles from me at Selby, Yorkshire around 1976.

    Turnigy Standard 9x transmitter
    Hello all. I hope you can help me before I lose all of my hair. I recently purchased a Turnigy 9x set which, according to all of the reviews I have seen, is good value for money. I am sure that they are all right but you need to be a genius to understand the instructions. Everything is in short hand. I am fairly new to the latest
    radio
    s but I can read. This is not good. The internet has been invaluable and I have found a good instruction book for the Flysky 9x which appears to be the same. I have now got through the basics but I am having a problem achieving what I bought it for in the first place. My latest build, a Pilot boat, has been wired such that I need to use three channels to operate rc switches. I would like to use channels 5, 6 and 7. I have found that I can set 5 to gear which gives me one switch, another can go to throttle something to give me two switches, but the other choices go to trimmers only. After reading bloggs it seems that I can get a third switch working on, say, channel 7, but have to alter mix settings. I am completely lost now and wondered if anybody could instruct me as to how to get this third switch to operate on channel seven. Thank you.๐Ÿ˜Š

    like the taranis. Each of your rudder servos can be on its own dedicated channel as can the ESC for each motor. Using the built in mixing functions you can "tune" the setup so as to get the effects your looking for plus you can do things like both rudders moving in opposite directions to give a brake effect.

    systems are computerised so you can do all the mixing you want from the transmitter. No need to buy mixers for the receiver end. Setting things up the first time you do it is confusing I agree but once you have a grip on things it becomes more simple. The good thing about using a modern system is that you can change things on the fly and even have different mixes selectable on the same model and change while your sailing. https://www.youtube.com/watch?v=Yq_H9vzCz8g there is a video so you can see what I am talking about.

    Bought this some years ago with a holed hull and no cabin. Made only those repairs needed to make it useable, fitted new 2.4Ghz
    radio
    gear and batteries, and have been using it ever since. I keep threatening to restore it properly but it's fun as it is and a rebuild is probably more realistic anyway. (5/10)

    Help with vintage rc.
    hi there I am in agreement with DodgyGeezer about the reliability of vintage
    radio
    gear. I believe the Digi4 servos were Linear movement, rather than rotary as in modern day servos and yes some of the old versions were 4 wire; with male plugs at the end. One of the main downfalls of these old sets was thing called 'black wire' its where the negative side wire in the electrical wiring system actually turns black and corrodes. The only way to repair it is to actually renew the wiring and once you have it in one part of your
    radio
    system, it inevitably works its way through the whole of your
    radio
    system. The transmitters do turn up on that popular auction site. I have often fancied purchasing one just to play around with it - but I wouldn't trust one operating a precious model on the lake, because I can remember the 27 mghz
    radio
    gear being very prone to interference from the slightest thing.๐Ÿ‘ john

    Help with vintage rc.
    I think the Digimax had interchangeable crystals - but didn't it also have 4-wire servos? if so, you will need a full Digimax set.... In general, it is not a good idea to use Vintage equipment unless you know what you are doing. The kit will be old, could need maintenance or repair (which may not be easy to source) and will have less range, reliability and interference rejection capability than modern sets. it will be 27Mhz. You may have to repair the electronics yourself. If you source a transmitter which SHOULD work with it, but doesn't, you will need expert attention to determine what is wrong - again, this will be hard to find. I assume that you do not know if that receiver works at the moment.... Running vintage
    radio
    s is rather like running vintage cars. They look great when they are operating properly, but need a lot of work to maintain, and do not perform as well as modern kit. One source of help might be the Single Channel and Vintage RC group here - http://www.singlechannel.co.uk . They have specialists in old equipment...

    1950s sea commander refurb.
    Good to see an early Sea Commander being restored. My first experience of seeing a Sea Commander was in early 1961 when I was eight years old. I was in Coronation Park in Crosby just outside Liverpool and dad got talking to the owner who said he had been a radar technician in WW2 and he built the

    BTW: I grew up with valves (or bottles as we Brits also call 'em) as well. I still have a box of several vintage 'bottles' in the cellar, many of them new still in the original boxes. if you ever run out of triodes, pentodes or tetrodes give me a buzz! Think I still have some pristine EL80s - collectors items these days - lots of Oomph ๐Ÿ˜ My next non-model boat electronic project is a pair of digital clocks in 'Art Deco' cases, using bottle decade counters. The forerunners of the fluorescent tubes and then the LED clocks, but much more fun๐Ÿ˜‰. About forty years ago I spent a year or so servicing and calibrating the radiation monitors around UK nuke power plants using these decade counters. One cosmic radiation click = one jump in the base counter and so on. Never ever saw anything above the basic cosmic radiation background count which is always there. A remnant of the 'Big Bang'. ๐Ÿ˜ฒ Funny where an interest in electronics and
    radio
    can getcha ๐Ÿ˜ Look forward to your chimney experiment report๐Ÿ‘ My destroyer has two funnels but I found that the little railway smokers were not man enough to feed two funnels via a branched tube. But two working in parallel off the one RC channel did the trick. Regarding the chimney effect; Works well at rest or at low speeds, but I also found that instead of a fan some traditional air vent scoops mounted forward of the smoker augmented the effect well at higher speeds. And my long thin destroyer with 2 x 540s on 12V made a lot of 'speed boats' look silly ๐Ÿ˜ Have fun, ciao, Doug ๐Ÿ˜Ž

    Wow Robbob, I have just seen the video of your Crash Tender. She is amazing. Looks great on the water. I just love the way these hulls sit on the water. Virtually no roll at all, it's as if they are glued to the waters surface. The Aerokits Crash Tender was my very first boat back int 1959, it was my 9th birthday present and my father and I started to a build. But he wasn't happy about building the original kit straight outright. As our first ever build, he brought home broken down tea chests and orange boxes and he got me to draw round all the parts and he went on to cut each piece out with a nice new fretsaw. So as the first one went together and it seemed to go well then the Aerokits one followed on. He then bought me a ED Hunter 3.46cc Diesel engine for my Christmas present that year. I say he I should say my parents both bought them for me. Sadly I never got to have
    radio
    control in it. I was weird as we went on to build another five in all. One was given to my younger brother, his had a Taycol Standard in it, and I had the job of taking the accumulator to the local model shop to have it charged up as we never had a charger for it. I think they used to charge something like a shilling each time it was done. The other five that we built he actually gave away to friends and one even went to the milkman. I still have a 34 and a 46 inch still new in boxes. The 34" is an original that Was Released in 1994 by Aerokits on the 50th Anniversary and the 46" is a VMW kit. I have a 46" to refurbish and have scaled one down and built a 28" in Balsa wood. As well as a 46" PT 109 with a 26cc in her that also sits on the water the same way. Sorry to waffle on it just brings back old memories. I'll leave it there. I just love your Build such detail.

    Hi Toby, that's exactly why I do not use a 'Dumbphone' for such things. I also have a Samsung so called smartphone, I use it for telephoning (now there's novel) and SMS and occasional snapshots if I don't have a real camera with me. First thing I do with a Smartphone is dump all the the bl***y pre installed Apps that I don't need and just take up memory space or constantly try to 'Call Home' and demand updates๐Ÿ˜ก As you have discovered; it's the Apps that are smart (or not๐Ÿ˜ฒ) and NOT the phone itself. Like any computer; 'Rubbish in = Rubbish out'! Before I left UK to work in Germany I worked for a year or so with the then Home Office
    radio
    Regulatory Department and the then 'start up' Vodafone on Acceptance Test systems for the phones and surveying for cell sites. it was pretty clear even then, reading between the operating software lines, where things were going! My first job here in Munich was reprogramming a test system for mobile phones so that it actually did what was needed to simulate the network and prove all functions of the mobiles. Searching for cell sites with two great guys from the Home Office labs was a lot more fun - but the Germans paid better ๐Ÿ˜ As you rightly noted 'Ich bin ein Nachteule'!

    I used to have a current single-engine flight license. The video shows the flying with my good friend John from Emilia Reed airport south from San Jose, CA to North Las Vegas north of Las Vegas, NV. On this flight leg we had clear skies. On the second leg we fly back to san Jase, CA. It was a rainy day and the clouds and sequences of the view do still fascinate me. https://youtu.be/0xcrbUhOkYs The video allows me to repeat that flight, seeing and listening to the

    My other hobby
    Hi. Mi private pilots license also does not include night flying. But interesting is to consider when they define what is included. When having a certain number of instructed night flights you are entitled to fly in the vicinity of an airport. Vicinity of an airport German definition is that you have to be able to see the traffic in the pattern of an airport. When I did my flight from San Jose, CA to Phoenix SkyHarbour, I was able to see the traffic being about 1.5 hours from the airport. The night definition is that the night begins 30 minutes after sunset. So was entitled to do this night approaches as you can see the traffic in the pattern, on a large airport like Sky Harbour, and in the Southwest of the USA from very far. But when doing these landing operations at a large international airport, shortly before touch-down you are flying into a black hole. Due to this on my first landing in Sky Harbour, I made an awful 3-point-landing making the plane jump 2 or 3 times. Fortunately, I was aware of how to react properly when this happens. The second special experience is when you are taxiing on the runway to get to its exit and report "runway vacated" in a small plane like a Cessna Cutlass the lights lose their structure. So I went to search for the yellow line on the left side of the runway until it curved into the exit. But this yellow line and the blue runway lights are hugely distant from each other so I had to focus my efforts to stay to the right of the blue lights but still being able to see the yellow line. Once I crossed the lines that mark that you are leaving the runway I could report back to the tower "runway vacated". My second-night landing was when I did try to fly to an airport next to the "Grand Canyon". As the report of the airport said expect gain or lose 40 knots of speed on final I decided not to land and flew back To Phoenix. What a wonderful experience. The landscape was already impressive on my flight to the Grand Canyon, but it was topped when I flew by night. First I was in contact with one center in charge while being above a certain altitude. Then this center passes you to one in charge below that altitude. Makes you feel like a professional pilot. Finally, this center did pass me to the tower of Sky Harbor. I was approaching from the north. Then, what controllers of large airports like they make you cross the airport midfield what ensures you stay away from the other traffic of the airport. You cannot imagine what a sight it is when you approach a large city like Phoenix by night. After he gave me its clear to land I was remembering my awful night landing earlier. When I did have the feeling that I was about to touch-down I did control the airplane so that all you felt on touch-down was the vibration of the wheels turning. A Geman friend of mine that was on the plane with me was so impressed that he said he would fly again with me at any time. One other fact I want to share is the importance to really dominate the phraseology of
    radio
    communication and what Americans call to know the system. On my first approach by night to Phoenix, I did confuse the last VOR with the ILS beacon. So when switching to what I thought to be the last VOR the needle got full to the right and stayed there. So I did a report I was not able to tune in the VOR and so tower did give me instructions for the further approach. When you fly in from the west you fly over a mountain full of antennas and the red lights on top of it. I felt very good being routed by the tower. Those of you familiar with night-flight and how to find the location of the airport know the rule of the black spot within the lights of the city is where the airport is. Well, Sky Harbor has the terminal building between its 2 runways and so Sky Harbor does not look like a black spot. So when the tower asked me if I had field in sight I did respond negative a couple of times until he reported that I was on the 45 for the runway. Then I finally saw the airport. Here is something that is the consequence of good
    radio
    training. My instructor always said to report negative until you are really enabled to say affirm. So Tower knows when you are really able to report affirm. Do not be shy, it is your and others life! The second time on that approach was when tower gave me the instruction: 3-60 to the right until further advice! My teacher played the role of the tower and one of the things he said to teach us the right behavior was to stay silent and fly as instructed until tower contacts you again. I do confess I had never done 3-60s neither by night nor during the day! So I put the plane into a standard curve, kept it there, watched my altitude and speed. Being so familiar with this instruction from the tower I felt "at home" and this being relaxed was very useful!
