    34 inch Crash Tender refit
    I posted a some pictures of my Crash Tender a few months ago and it was suggested that I should do a blog. So here we go. This is my first blog, and my first boat. I am not going to provide a blow by blow account of the refit, as this would largely turn into a repeat of the excellent blogs by Rob (Robbob) and Mike (mturpin013). These two blogs have been a great inspiration and source of guidance for me over the past couple of months. I built the boat in the early 1970s, but haven't had it on the water for nearly 45 years. Until recently, it had been collecting dust in my garage for all that time. The first task, having given it a good was to remove most of the dust, was to remove the ED Racer diesel engine, fuel tank, exhaust, etc and to fill in the exhaust hole in the transom. The diesel had always been a challenge to start, and to keep running. That, together with the unreliable, home built 27MHz
    radio
    gear is the reason the boat had been in dry dock for 45 years. A new brushless motor, water cooled ESC and 3S LiPo battery were installed in place of the diesel. The propeller also needed replacing as the old one was too large. This identified the first problem. Times have changed since the 1970s and props now have metric threads, whereas my 1970s propshaft had a 4BA thread at both ends. A new 4mm silver steel shaft was fitted threaded M4 at each end. The new shaft diameter necessitated also replacing the plastic bushes in the shaft outer. Plastic bushes were probably not a good idea in any case. New phosphor bronze bushes were turned and fitted and it was then time to get it back on the water. The first trial was very encouraging. The modern
    radio
    worked well, the boat was easy to start, quiet, and performed better than it ever had with the old gear. When I originally built it, I did not fit chine strakes. I cannot remember now why. It may be I didn't realise they should be fitted, or perhaps I felt they would spoild the smooth lines of the hull! Even without them it did manage to plane a little. Being fired up with enthusiasm after this first trial, I decided it was time to get back into the workshop, fit the missing strakes and start the refit propper.

    This boat was recently purchased on-line from the grandson of the 1:1 boat in the photos. He built the boat from old photos and his memory. This is truly a "pond yacht" as the is no access to below deck for any
    radio
    control equipment. The plan is to keep the boat as shown but to up up grade the deck hardware and aft deck details. It is powered by a small electric motor running on one "C" cell battery. 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. in the interim I've added a few more photos of the update to the trim. You'll notice the companionway now has a door and hatchway. Unfortunately it blocks the view of the detailed interior the builder made. There are some additional items that have been added since these photos were taken including more detail to the control panel and a steaming light and stern light. I'm undecided about adding a small boat to the cabin top as a lifeboat/dingy. Time will tell...

    Exactamente Dodgy 👍 Martin is also correct. Point 2 was discussed a few days ago in a similar thread. The earth wire should be soldered or clamped to the prop tube of earth plate though. A loose connection like a croc clip can itself be a source of interference; so called "Metal to metal noise". That's also why I don't like all metal UJs for the prop shaft. Even 1:1 ships can suffer from problems with earthing plates! In the mid nineties I designed a COMMS system for a series of glass fibre minesweepers. Against my better judgement the yard decide to use vertical whip antennae for the HF

    s. A vertical monopole whip antenna needs a good earth to act as it's counterpoise. "No problem " said the yard "We'll let a copper earth plate into the keel." After launching and a few weeks of fitting out and trials they complained that the HF comm efficiency and range was deteriorating. We tested all our
    radio
    s, ATU and cabling and all was OK. Then we sent a diver down to inspect the earth plate. He came up and said "It looks like Chantilly lace!" Red faces at the yard and they coughed up for the Crossed Dipole antenna (with it's own built in counterpoise and ATU) which I wanted to fit in the first place 😉 Cheers, Doug 😎

    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.

    EeZeBilts From Keil Kraft
    "Perhaps DG is the best one to answer this -" Dunno why - my boats will sink like anyone else's if they fill up with water. Partly it's horses for courses - don't sail a boat with a low freeboard on the choppy side of the lake where the waves break over the bow. Fast boats which deflect water away might get away with it - slower displacement hulls where the water creeps up the side won't. Google 'Coandă effect' for a more technical description of the reason water sticks to surfaces. Tugs usually have heavy ballast and are more likely to have waves breaking over them than to ride up and over them. And sealing a deck effectively is going to depend very much on the way it's designed to fit on the hull... Adams of Adamcraft fame in the 1950s used to stretch clear plastic 'clingfilm' over the decks of his open boats (it was invented in '49!) to keep the water out, and you might find that trick useful if you have to have a removable deck. The clingfilm would go underneath the deck, of course... Sinking is less of a problem with EeZeBilts (though the Beaver with its heavy ballast would go down). They are made of many watertight compartments. If your boat doesn't have such flotation support, try using expanded foam in all the spare cavities. I do this in my boats, partly as a safety measure, partly to deaden the motor sound and stop the decks from 'drumming' and partly because I mount batteries and
    radio
    equipment in it. Here is a shot of a PT Boat with removable centre deck, which is happy in heavy waves - you can see the foam blocks...

    46'' RAF Crash Tender
    Ik, That's quite an easy set up compared to what I had to deal with on the 36" HSL as I had a lot to fit in a small space. The center of the boat is inaccessible due to the wheelhouse (which is removable) having a drop floor, (apart from 1 1/2"under it where the ESCs and one speaker sit) and the bow area originally having no large hatches. I had to make one to get the 2 sound units (plus speakers) and
    radio
    gear in. Rear deck behind the engine room is the same with only one lazarette and the dinghy on top. I didn't want to make another non standard hatch, so I managed with the space that I had. Had to do a similar thing to my 36" Thornycroft MTB. Thought about transfer boxes (see pics) but was too much work to get all the angles right, (although the one with a motor might be tempting on a future build) and motor space wasn't wide enough. Also the weight in the stern was another factor, (sits too deep in the water at the stern already but luckily runs nicely anyway.) It's fine if you don't have floors or interior detail, as you have a lot more room to play with, but I prefer to keep everything up off the bottom in case water gets in. Also the floors give you somewhere to place everything on a flat surface . John B

    s on 2.4 are way less susceptible to interference. None of my models have suffered with any form of electrical interference since I changed to 2.4 from FM and previous to that 27Mhz which was shocking!. As previously mentioned I have 18 aircraft -mostly out-runners up to 1100w , a few in-runners-(ducted fans) and at the moment 5 boats (1 with twin in-runners, 1 with twin non suppressed 380s, 1 with single suppressed 380, 1 with twin non suppressed 540s, and 1 with a worn out old Graupner monoperm. I have run 2 brushed boats together on 1 TX and a brushed and brushless on the same TX both with single wire RXs in each boat paired to the TX) with the boats 1ft apart at times with not a hint of a problem (RECs in the bow). I have always made sure the aerials are not in line with pushrods or near anything that might create any sort of magnetic field, and RXs as Doug said, on the opposite side to anything of that nature. Also as mentioned, any twin aerial RXs should have each leg at as near to 90deg as possible or at least 1 forward and 1 aft (planes and boats) Not sure If I'm doing something right or it's the
    radio
    s I'm using (5 different types- 2 are HK cheapo 2.4s- general lack of serious outside interference or if I'm just plain lucky, but I have enough of a variety of installations to show that in my opinion, if you are having a problem on a 2.4 set-up there must be something quite unusual happening. I'll bet it would be something easy to fix, (like first take your gear out and test it to make sure it's not that, then look at aerial/ REC placement, twisted/coiled wiring etc. I noticed that the REC aerial on your boat Ron, goes over the top of the steel rudder pushrod -could be something as simple as that. You just have to go through things step by step until you find what's causing the problem (obvious statement I know) Doug mentioned ferrite rings which are a good idea (I found some clip on ones on HK which you can put on leads easily) I also use UBECs on all my planes which have a ferrite ring fitted which are a good bit of insurance.

    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 glug😭😭 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 😮😭 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 / surfacing🤞. Cheers, Doug 😎

    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

"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

    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 😎

    if interference is the primary issue. To convert you need to obtain a
    radio
    module, and then find the position in your transmitter where the signal is passed to the RF section. You then connect Vcc, GND and Signal to the new 2.4Ghz module. Some
    radio
    s have a separate RF board, making this part easy, but if not you will need some way to find the bit to connect....

    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.

    Fiddly bits and lights
    Hi y’all. She’s almost there. I swear for a fairly easy boat to build I have almost as much time in the thing as my Neptun.😮 I keep adding a little here and there, but I need to finish her. Once I maiden her, I’m “done” I rarely go back to a project I’ve finished to modify or add details, with the exception of RC cars. The more I get into model boating however, the more I think that attitude might change. Anyway, I bought some detail pieces from Harbor models in California, and decided to add lights to the Acapulco too. The flying bridge now has a
    radio
    s and a fire extinguisher. I took braided wire, stripped off the insulation and used that inside a piece of heat shrink for the hose, it’s not perfect but looks ok. I shortened the radar mast that goes behind the seat because...well, I just didn’t like how it looked. I added 2 aft nav lights to it also, I’m waiting on lights and boards from Harbor, once those are installed I’ll tidy up the internals, pinstripe the water line and she will be ready for her maiden run. I need to get her done as I have another project in the wings,and I’m gonna have to do some engineering to accomplish what I want I have in mind....😁 Cash

    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.😊

    2.4Ghz TX/
    radio
    combo With the introduction of the 2.4 Ghz
    radio
    s the 27Mhz and the 40Mhz systems will soon become obsolete, they are however the only ones suitable for underwater submarine use as the 2.4Ghz will not transmit under water. With the 2.4Ghz system you can forget about wrong crystals; or is somebody on your frequency; dual conversion; incompatibility of some crystals on some
    radio
    s; interference etc etc. need I go on. The first 2.4Ghz systems were expensive but now a transmitter and
    radio
    can be bought for just under £30 there seems to be no point in hanging on to your old 27 and 40 Mhz
    radio
    s.... START to update for a hassle free life. Additional receivers are only £10. It seems that the Planet and
    radio
    Link are no longer readily available. FlySky are a suitable in-expensive alternative but are not compatible with Planet or
    radio
    Link. A simple,one off binding process for your first time use and your set is tuned to just your transmitter. You can use just one transmitter and have all your boats fitted with receivers which will only receive signals from your one transmitter. Should you for any reason want to add or change your transmitter for the same type you can simple re- bind your receivers again to match your new transmitter SIMPLE !!!! If you do have a rather expensive 40Mhz Transmitter it is possible to purchase an adaption kit to 2.4Ghz and still retain your transmitter, 2.4Ghz 4 to 6 channel receivers can be purchased for as little as £10 to match the modified transmitter.

    What type of antenna is this?
    The wire aerial running between the masts is what
    radio
    hams call an inverted L, it is tuned against the hull of the boat and the seawater and unlike a half wave dipole it only needs to be a quarter wave long, or less with a loading coil and an aerial tuning unit, often built into the transmitter. Common on many fishing boats in the days of the Trawler band, which is the frequency band a bit above medium wave. Trawler Band was also nicknamed FishFone.If you mean the loop aerial on the wheelhouse, that is a

    RC circuit
    Since your going to replace your Tx and Rx consider a computer
    radio
    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. Setting up the mixing looks difficult but once your into it, it follows a logic. https://www.youtube.com/watch?v=Yq_H9vzCz8g&t=21s

    Robbe Westerriff lotse pilot vessel
    This boat is understood to be a Robbe 1:25 kit, constructed to a very high standard, and is the pilot vessel Westerriff. The craft is finished to the most exacting of standards and, whilst fitted with a motor, bow thruster and lots of wiring, will need additions and finishing to perform, with, battery,
    radio
    gear etc required. ( I also note there is no servo for the rudder ). It has sailed previously, and is provided with many attractive features, including operating water cannon, rotating radar, operating mast lights ( numerous ). The length is 106 cms, or a tad under 42 inches in old money.( The craft is supplied without the stand that is shown in the images. I am presently looking for a suitable stand, so if there is one out there to be had, please do let me ( or the new purchaser ) know. If further info or images is/are required, please do let me know. Again, I am looking for a reasonable and realistic offer for the boat, and all offers will be considered. The craft is presently moored alongside the previously mentioned Assurance class armed tug in South Manchester. ( also, the least I can do is to ensure that a suitable donation is made to the site following the sale of any of the craft that I am offering for sale ).

    Receiver aerial
    The modern digital
    radio
    control Tx/Rx aerial is attached directly to the device. I assume, as normally is, that the Tx/Rx connection impedance is 50 ohms. A quarter-wave vertical aerial is also 50 ohms. Can one extend the aerial using 50 ohm co-axial cable so as to leave Tx/Tx in hull and place aerial on top of a mast?

    Receiver aerial
    Hi there, I presume that you are referring to 2.4ghz
    radio
    system. I have various models using 2.4ghz and have not had to extend the reciever aerial on any of them. Most only have about 50mm above the deck and I've been in full control up to 300 mtrs (28 acre lake) with the older 27mhz. Or 40mhz I have to have a fully extended aerial to get a good reception at distance. Hope that this will help you. Cheers Colin.

    hi ya Marky, judging by your building skills - it wont take you much to move right over to
    radio
    controlling a model - if you have the skill to master building, you have the skills to master
    radio
    control. Go for it :-) heres an idea, look on some of the websites who sell
    radio
    gear and buy yourself a reasonably priced 2.4 handset with the receiver then you can purchase a couple of servos to plug into the receiver along with a battery to power it all and then have a play around and find exactly what it does, and then programme if needs be. Golden rule, 27MHz 40 MHz &2.4 can be used on the land and on water only. 2.4 along with 35 MHz and be used for aircraft only. So 2.4 is the only one interchangeable between land and air. Basic rules for buying a transmitter in the UK anyway. amendment ,27MHz can also be used for aircraft👍 john

    Slightly confused newbie
    John, I followed the video exactly, using ch.3 instead of the ch.2 recommended with the
    radio
    gear, but then I could not get response from the esc. Mine is a 25amp; would that make any difference? I then switched it back to ch.2 (having already reversed the motor leads) and ran the setup again. The throttle now runs in the right direction, but if I switch the trim to normal, the motor runs at full speed forward. Switching it back to reverse, it functions normally. What am I doing wrong??

    Its really quite simple modern
    radio
    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.

    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.👍 john
