    36'' Thames River Police Launch by Robbob
    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.

    (Working Vessel) Northlight Clyde Puffer
    The Clyde Puffer is a Caldercraft kit of 1:32 scale. it is a representative model of a typical small coaster from the Western isles of Scotland, known to many ship lovers as a 'Clyde Puffer'. it has a GRP hull which has full external detail, riveting, strakes etc. and a plywood superstructure and decking plus over 200 white metal fittings. As usual for Caldercraft you need to have your thinking cap on as the A0 plan and the 'instruction book' do not match up but of course they do expect you to have a little bit of experience in model building. it has taken me about 6 months to build, but working on and off over this time. it has a large hull which is easy to house the
    motor
    , ESC, RC and batteries, etc. (I installed 2 lead acid 6 volt batteries, one on each side amidships) which gives stability and ballast. Being a large deep hull it needs a lot of ballast, even in its short length. I have only tested her in the big white test tank at home so do not know how it will perform on our lake. I have sailed her many times on our lake and she certainly sails well. I installed an electronic switch for the navigation lights and gives a good effect during the darker afternoons/evening. (

    Re: Enclosing the controls.
    Hi Alan. You are correct, I had tucked that leg of the aerial alongside the ESC and probably would have used that position but I'll take your advice and move it away as far as practical. I'll put it in a thin plastic tube at the front of the enclosure so it will be correctly distanced as you rightly suggest. I had not considered that any nasty RFI from the ESC (or any other acronyms 😉) would be an issue with 2.4G kit. The other leg of the aerial is passed through a hole in the side wall of the well deck into the hull cavity and extends forward, it's also above the waterline too so that should be OK. The aerial wires will be at 90 degrees to each other which I know is desirable too. BTW. I have developed the fan cooling of the

    The well deck floor & sides.
    The ‘box’ of the prototype I’m building is made of balsa wood, later production models are produced in ply and have the planking lines laser etched on the floor panels, and as balsa doesn’t take stain particularly well I have used separate obeche panels to line the box internally that can be finished with the Teak stain that I’m using. This does, however, mean that I can apply the deck lines using a black indelible marker pen and incorporate some detail lines around the
    motor
    housing. I started by cutting and shaping two obeche panels that join along the centre line of the deck and fit neatly around the
    motor
    mount and prop-shaft, then I used some tracing paper over the panels to make a test pattern for the planking lines. When I was happy with the layout of the lines I first applied two coat of Teak stain to the panels, and when that was dry I used a .8mm pen to mark the deck lines, the ink takes a while to dry fully and I found it all too easy to smudge some lines 😡 which had to be very quickly taken off with a dampened cotton bud and re-applied. After 24 hours the ink had fully dried and was impervious to smudging and resistant to removal by any means (except a solvent). The floor panels were then glued down to the balsa floor with an even spread of aliphatic glue and weighted down over all of the area as there was a tendency for the panels to curl and lift. Each side panel was made in one piece and then separated into two parts to make the fitting easier, the join will be covered with a vertical detail strip, and they were also stained before being glued and clamped in place. No lining detail was applied to the side panels as I’ll do this with other surface applied pieces later but only in the area outside of the cabin. All the panels were given a couple of coats of satin lacquer to enhance and protect the finish.

    Servo Mount
    Accidently deleted posts - Response by JOHN on the 6th Mar 2019 Modify ✓ Like This Post ( 3 ) hi there With regard the servo rudder linkages - I was advised that it is always best to use the 'push/pull method' of linkage - as this has two strong points in its favour. The first problem it alleviates is - sometimes if on a single connection between rudder and servo and it is not set up quite right - a servo movement can force the rudder tiller arm to come back on itself under certain circumstances - i.e. when the distance from the centre of the servo to the outer hole on the servo arm isn't equal to the centre of the rudder post - to the centre of the linkage arm on the rudder. The second problem - you can get an odd strain on the gearing in the servo, because on some models there is a fair bit of force on the rudder blade - whilst the model is in motion & turning to port or starboard. The way to think of this, you are riding a pushbike and holding the handlebars with one hand and you are trying to turn a sharp corner - think of how much strain and effort you have to put in. Now, if you have a double linkage to either side of the tiller arm from your servo - that strain now is balanced and is evening out the strain in the servo. Admittedly, this problem where you wear the servo out only happens on very rare occasions - but - as the old saying goes 'belts and braces/better be safe than sorry'. John Response by RNinMunich on the 6th Mar 2019 Modify ✓ Like This Post ( 1 ) In the wrong post but sensible stuff John.👍 Hadn't considered it before but it certainly makes sense to me that a dual linkage will help cancel the backlash from the rudder. And hence stop the servo
    motor
    having to fight it. That would reduce potential 'hunting' of the servo and also take the strain off the gearing. Probably not a noticeable problem for short term rudder commands or in small, light models. But could be in the heavyweights with big rudders I suppose. like Mike said (sort of); makes yer think!! More power to yer servos Gents. Cheers, Doug 😎 PS Dual linkage not possible in some situations, see pic of cramped space in my Sea Scout. Had to lay the servo on it's side.😲

    Cooling the
    motor
    – update.
    I’m grateful to mturpin013 for commenting that he considered using the propeller adaptor supplied with the Turnigy
    motor
    as it prompted me to retrieve mine from the box and adapt it to secure the fan on the end of the
    motor
    . I cut off the threaded shaft from the prop adaptor and the end was ground flat and then I placed it on the end of the
    motor
    stub and used a scriber through the bolt holes to mark the positions on the flange of the fan. The fan was then removed and the holes drilled through and opened up to 3mm and then it was a simple matter to put the fan back on the
    motor
    and attach the new piece to the
    motor
    using the three 2.5mm cap head screws which are supplied with the prop adaptor. I think this is a far better ‘engineering’ solution to securing the fan to the rotor than a spot of CA. Because the addition of the fan was so straightforward and effective I have decided to implement it on the model anyway so I cut an opening through the end panel of the
    motor
    cover and put some stainless steel mesh over that to finish it. The
    motor
    is now connected to the ESC and I have done some tests with the
    motor
    running and I’m delighted to report that there’s a very healthy airflow through the
    motor
    cover 😁👍. It turns out that my modification is not unique at all and credit is due to reilly4 who did something similar to the twin

    Canabus, Hope this helps, Rowen Using the FS-I6X instruction Manual, dated 8/10/2018. This Tx allows infinite experimenting with the various control functions and ultimately reverting to factory settings if dissatisfied with results. After several attempts at setting the ELEVON function (V-TAIL could be similar, but the Tx channels would be different), decided this works best for me. it puts both brushless ESCs on the RH control lever. Moving it up operates both screws in the forward direction and down into reverse. Going from side to side speeds up or slows down the
    motor
    s, so the boat goes in the direction the lever dictates. This was accomplished by: 1) Page 14/57 Establish the Tx Stick mode, mine was # 2. 2) Considering ELEVON, need to determine which layout allows the Aileron and Elevator controls to be operated by same lever. 3) Use Elevator for throttle (fwd & astern) and Aileron to “turn”. The Aileron will accelerate the
    motor
    on the outside of a turn. 4) Plug Port & Starboard
    motor
    ESCs into channels 1 & 2 respectively. 5) Refer to Para 5.10 and set Elevon mode on Tx. 6) Use channel 4 (LH lever side to side) for rudder and Channel 3 (LH lever up / down) for any other function needing proportional control. I am using it for the centre brushed
    motor
    . This means that my control levers, which had previously had throttle on the LH lever and rudder on the right are now totally changed. There is also an article in the March edition of Model Boats that explains the concept.

    During our protracted wait for Spring, have had chance to reflect on the earlier tribulations with the brushless
    motor
    installation. My enthusiasm was sparked by an article on getting the best from your Tx in a magazine and the advantages of using the Elevon or V Tail facilities if available. My Flysky Rx/Tx has this facility, so after some experiments, set the boat up to use the Elevon function. This puts both
    motor
    ESCs on the same control lever, so advancing the control accelerates both screws equally and moving to either side accelerates, or slows the appropriate
    motor
    . Think this will reduce the coordination previously required to sail in a straight line. Fresh from that success decided to experiment further. The Tx allows reducing Servo throw, so tried that too so could reduce the max. ESC output, it also seems to work. One problem with the original layout was that if the forward speed was reduced quickly it was very easy to move the lever through the neutral point, overshooting into reverse. This immediately reversed that
    motor
    causing erratic operation. The Tx also has a “Dual Rate” facility to adjust the lever response from linear to various alternate rates. This allows the neutral point zone to be increased, so the tendency to overshoot into reverse is reduced. Bench tests of these adjustments suggest the model will be easier to operate. Hope they will make controlling the models performance better in our closest pool, which is quite small. A further precaution to prevent inadvertent operation of the brushless
    motor
    s when using the centre, brushed one, was to add two small relays; one into each of the white ESC signal wires. This allows a another channel on the Tx to be used to select, or deselect the brushless
    motor
    s. Anticipate that by turning this channel and thus the brushless ESCs off, manoeuvring can be accomplished without the operation being overwhelmed by a brushed
    motor
    inadvertently being operated. My patience for Spring is getting thinner!

    Hi Stuart, At 23" your Huntsman is only a tad smaller than my 24" Sea Scout which I refurbished last year, look for the build blog 'Jessica - A Sea Scout restoration' on this site. I fitted a 1000kV 28mm Propdrive
    motor
    and Quicrun 16BL30 30A ESC from Hobbywing. including the ESC programming card the whole kit an' caboodle was just under 40 dollars from Hobbyking.com. With a 2S LiPo (7.4V) performance was sedate to adequate. With a 3S LiPo performance is 'twinkling' and a lot of fun to drive. Check out attached video links. Pt1: https://youtu.be/zPgYicA0yGw First run with a 3S LiPo. Pt2: https://youtu.be/oMUlSOaAREM 'The competition'! Pt3: https://youtu.be/b0BWJ3duzDw 'Final run', the Bier was getting warm Prop is a brass 30mm 3 blade from Raboesch. Hope this helps, Happy Sailing. Cheers, Doug 😎 PS Video is in HD 1080p, taken at the Ostpark Lake in Munich (adjacent to the Biergarten😉😁) May 2018.

    In the wrong post but sensible stuff John.👍 Hadn't considered it before but it certainly makes sense to me that a dual linkage will help cancel the backlash from the rudder. And hence stop the servo
    motor
    having to fight it. That would reduce potential 'hunting' of the servo and also take the strain off the gearing. Probably not a noticeable problem for short term rudder commands or in small, light models. But could be in the heavyweights with big rudders I suppose. like Mike said (sort of); makes yer think!! More power to yer servos Gents. Cheers, Doug 😎 PS Dual linkage not possible in some situations, see pic of cramped space in my Sea Scout. Had to lay the servo on it's side.😲

    I would have thought the
    motor
    size would be given in the build instructions or on the plans given Dave Milbourn's (the kit designer) attention to detail. Chris

    Servo Mount
    The servo mount on my Crash Tender came from China, unfortunately I don't have the machinery or skills that Mike has. I found the single linkage to be more than adequate. reilly4. I note that your
    motor
    s have fans attached (first 'photo), are they standard on those
    motor
    s ?

    Aziz, Westerriff, Assurance Envoy for sale
    Thank you for your kind comments, and yes, all of the ships have been built to a very fine standard. With the Aziz already fitted with two
    motor
    s and rudder servo, there is little to do in order to set sail. They have all sailed previously, and I think that some of the RC components may have been transferred from one to the other, dependant upon the flavour of the month at the time. I can't sing the praises of these craft enough, they are impressive in every respect. They aren't in the way yet, but I am fearful that constant working around them could result in damage, so they sooner they sail off into the distance, the better. :-) Don't be afraid to make an offer, I do need to sell them all. Many thanks, Dave ( the site will also benefit from a sale, as a suitable donation will be made ).

    What size brushless
    motor
    ?
    I'm building a new Fairey Hunstman 31 from a kit bought through SLEC. It has provision for a single prop shaft and I've bought a 2 bladed plastic x-shape prop, 25mm based on a recommendation from SLEC. What is the best/most efficient/most powerful brushless electric
    motor
    / battery combination I can fit? I'm a novice at this and my previous boat kit had all parts supplied. Thank you in anticipation....👍

    As far as brushless

    s go I wouldn't know. But I think that you would still need to experiment with various props sizes to get the best one.

    Hi Stuart I think Dave Milborne used a 1000 or 1200kv 28mm brushless. You can PM on the model boat forum site. He is the kingpin on Huntsman's and is Fairley helpful guy . Canabus

    Friday's Child Fairey Huntsman 31
    Hi Boatshed....How is our refurb going? I'm currently building a new Huntsman 31 from a kit bought from SLEC. I've just started so keen to get as much shared info on any "gotchas". I see yours has a single prop....what
    motor
    does it have? My kit is single prop and want to get the most economical/powerful brushless as I can, but as a novice, don't have much of an idea at present.

    Fairey Hunsman renovation part 6
    I'm following your Blog with interest as I'm currently building a Huntsman 31 from a kit bought from SLEC. I'm building the hull from ply and getting the curves right on the hull skins is proving challenging. Mine has only a single
    motor
    and rudder. Good luck with the renovation work👍

    (Working Vessel) Mowe 2
    I hadn't build a RC model for over 45 years, so as a 60th Birthday present my wife bought me this Aeronaut Mowe 2 kit, complete with all the RC equipment;
    motor
    , servo, transmitter and receiver, ESC unit etc. It was a great kit to build and took me about 3 months from start to finish. The hull was a bit tricky, but a tube of P38 and lots of sanding, re-filling with light balsa filler, re-sanding, finishing and painting and patience won through! Not a brilliant finish, but an ideal boat to get my hand back-in to modelling. When sailing, the boat needed a bit of ballast in the form of 2 old AA batteries in the bow to keep it stable and level in the water at speed! (ESC: Aeronaut) (8/10)

    Back to 12 volt Smoker!
    Well, I got back my 6 volt smoker. I had sent it to be looked at. Just wasn't smoking a lot. But, everything checks out OK! I like the 12 volt Smoker instead! So, I'm ordering another 12 volt smoker and a 12 volt
    motor
    ! The 12 volt smoker tends to smoke more. I figure I'll use the 6 volt smoker and
    motor
    . For my next build. Which will be the Tug Douglas Greg 1/25 scale! See the 6 volt smoker. Smokes like a diesel throttling up! I'm going to make the Douglas Greg a diesel Tug! Here is the 6 volt smoker compared to the 12 volt smoker! 6 volt smoker: https://youtu.be/hSWIXL0nuZE Versus 12 volt smoker: https://www.youtube.com/watch?v=FtVIb7IZJiw&t=21s

    I considered doing this on the crash tender using the supplied aircraft prop adapter that the
    motor
    came with so Ill be interested to see how it performs.

    That's a very interesting idea Rob and one I've not seen before. I've saved a photo in my PC folder of
    motor
    related items. I think that if you are going to keep it as a permanent feature a drop of cyano would be a good idea despite the tightness of the push fit. Alan

    Cooling the
    motor
    - an experiment.
    Whilst I don’t think I’m going to need to cool the
    motor
    it got me thinking that it may be a useful experiment to see if the ‘Stick A Fan Blade On The End Of The Rotor’ idea would actually work 🤔 So while waiting for some glue to set on another part of the build I decided to rummage through the junk PC bits box and find an old fan of a suitable size, and I did indeed have on that would fit the bill 😀. I broke away the outer fan casing to release the
    motor
    and blades and then set about separating the fan blade, which proved fairly simple. The fan blade has an overall diameter of 45mm which is ideal and there’s a moulded-in centre mark so I used a step cutter to open up a hole to 10mm and then a tapered hand reamer to carefully open up the hole to about 11mm which is the diameter of the end bearing stub on the rotor. The fan was then pushed onto this
    motor
    stub until it seated flush on the wide and end of the rotor can and is a very tight friction fit so it doesn’t need any more than that to hold it. I don’t have a dial gauge but I can tell by eye that the fan is perfectly centred and true and so it shouldn’t cause an imbalance 🤞. The
    motor
    turns clockwise when viewed at the fan end which means that the fan would be pulling air through the side vents , through the stator and around the rotor and would need to exhaust through a new panel cut into the end of the
    motor
    enclosure. The existing
    motor
    enclosure still fits perfectly over the
    motor
    and its fan and wouldn’t need any other modification than the extra opening and mesh. So in theory this arrangement will give forced ventilation and cooling of the
    motor
    in the event that there is a heat problem. In practice I’ve yet to wire up the
    motor
    to the ESC so I have not been able to run a proper test to check it actually works but I’m pretty confident of it. This
    motor
    cooling arrangement could prove useful to others when faced with a similar situation which I why I decided to conduct the experiment...... and validate my theory. Just keep your fingers away from the fan blades…..😨
