    Futaba F14 Dual Thottle Installed!
    The F14 is quite a nice controller. It's extremely expandable from 8ch to I believe 32ch's! I'm going to expand mine to another 12ch's! For a total of 18ch''s maybe! The controller doesn't come with well written instructions. But, You can make out what to do to the controller! The modification from double
    stick
    to dual throttle and
    stick
    . Was fairly easy to do! It's all plug and play! It's some what intimidating. To look into the controller. And see all those wires. But if you take your time. it can be worked on with no difficulties! It took me about half an hour. To do the modification! But, I can't test the controller. Because it comes without batteries! I was trying to source them form. Cornwall model boats but they're out of them! So, I'm going to have to wait. To see who I can order from! Patients is a Virtue!!!!๐Ÿ‘

    Krick and Hobbyking
    Hi guys and Gals. I do not blow the trumpet for suppliers too often but I just have to mention the superb customer service I have received from both Krick and Hobbyking. 1) Krick. The Dusseldorf model from Krick I am currently building has a superstructure mainly formed by one piece of blow moulded clear Lexan which incorporates all of the windows also. The windows are covered by preformed
    stick
    on masks which are supplied on a pre-cut sheet. Just peel and fix. Well, I peeled and fixed a few a little out of place. They were so difficult to remove that I damaged the corners. Not much good for spraying. I wrote a note on their web site asking if they could give me a price for a replacement sheet. They wrote back the next day saying they would replace it f.o.c. True to their word, it arrived today, three days after my request. Well done Krick. Good products too I might add. 2) Hobbyking. I like Hobbyking. The products are good but their customer service is excellent. Over the last couple of years I have made many purchases and two have gone wrong.The first was a Li-Po battery. One cell was down when it arrived. I went to customer service on the web site and it asked me to take two pictures, one of the battery serial code and one of the battery connected to a monitor showing total voltage. I did this at 2pm. At 4pm I had an email approving the claim and a replacement was sent the next day. The second claim was this week. My relatively new Frsky Taranis X9D Plus (six months old), strangely started turning itself on, beeping, and the screen flashing and then off again repeating this every 30 seconds. The only way to stop it was to remove the battery. I wrote to Hobbyking on Sunday advising them of the error. On Monday I had an email asking for a video of the problem. I sent this on Tuesday. On wednesday they responded by saying that they had not seen this problem before and to send the unit back to them for replacement. They sent three emails over two hours today. The first said that they had received the faulty unit and that it would take around two weeks to assess and respond. Well that became one hour. They wrote again and said that the claim was valid and passed on to sales for replacement. Sales wrote one hour saying that a replacement was not immediately available and a full cash refund would be made. Five days and sorted. I can now buy a replacement. It would be good to hear of others good outcome supplier stories, or in fact the horror stories too.

    Re - I still don't understand why JB needs two RXs in his boat either. I'm supplying a free shovel Doug (shovel-Doug- get it.๐Ÿ˜‚) The reason I have 2 RXs is that the new compact sound unit has a main power in and a 'throttle' lead to the RX (self contained module with speaker). The 'throttle' lead is Siamesed with the ESC throttle lead then to the RX. The other unit is a multi function module with a separate speaker, and for the throttle, it has a port for the throttle lead from the RX which then goes out a port in the other end for the ESC throttle lead. I am using a converted Mode 2 TX (twin throttles) so 1 ESC/sound for STBD is on r/h

    (ex elev) and the Port side is on the left hand

    (ex Thro). If you plug the new unit into port no 3 (throttle ) and the other into the elev channel you get some sort of feedback (even took out the Pos wire,- still does it. Solved by using ch3 on the second RX, Can you dig it? I didn't get where I am today by not confusing people!!๐Ÿ˜ JB

    Hi Red, Now that you have explained what a "

There is nothing worse than trying to understand some of the more complex stuff when you can't understand the simple stuff first.

    Iโ€™ll buy what I need, but I am a CASO at heart (Cheap *** Studebaker Owner) so I will recycle things such as pushrods and clevises. When I flew RC combat I built models en masse, so once I was done with that I found myself with a lot of cut down pushrods around 5-6 inches long. Iโ€™ll take those, cut them in half and use small carbon fiber or fiberglass tube cut to length and ca the cut pushrod halves into the tube, making a very stiff, strong light pushrod. If the pushrod halfโ€™s slip too much in the tube, then before gluing, Iโ€™ll tweak a slight bend or nick the metal so it gets a good purchase inside the tube then run thin ca into the joint. Never had one fail. Also, baking soda and thin ca acts like concrete, makes a decent filler but can be ugly if over done. Donโ€™t breath the fumes!!! Sometimes Iโ€™ll have small parts that need to be painted, and my lack of patience makes want to paint the thing in one shot. If itโ€™s a part where the bottom is glued down and wonโ€™t be seen, Iโ€™ll tack glue a scrap piece of balsa
    stick
    to the bottom, paint the part then gently put the
    stick
    in the vise to keep the assembly upright while the paint dries, then break off the
    stick
    and glue the painted part in place.

    I agree with CPO, soon to be Warrant Officer, Rooky that the show was not up to standard. I heard someone saying how disappointed he was a couple of minutes after arriving. I did not think there were as many models on display, I didn't think there were as many trade stands and I heard several people say that the 'Bring and Buy' was far below what it normally is. Attendance looked as if it was down too. In fact getting around with a wheelchair was quite easy. On the positive side I thought there were some excellent models on display though as a '

    and string' lover I thought there was quite a lack of sailing craft. At any show, there is always a preponderance of motorised craft but I do regret seeing less and less scale sail around. To me, the best sailing exhibit was a model of an Albert Strange yawl and by the same builder, three models of Thames A Raters showing how they developed around 1900 under the influence of Linton Hope and Dixon Kemp. However, to me the show was not entirely lost as I picked up a moulded hull from Dave Watts, 'Mastman' for my next project a 1/24 Thames Sailing Barge. Altogether, I'm glad I went, I was a bit disappointed, but whether that will influence my decision to go or not go next year, I'll have to see. Happy show going, Nerys

    Re: 40'' Seaplane Tender, new build Y
    Yes, all channels are as they would be normally and both RXs operate identically. You could have a servo plugged into Ch2 on one RX and a pump on Ch 2 on the other, and when you moved the
    stick
    they would operate as one (probably not a lot of use) RXs need to be independently powered also, not linked in any way. As I previously mentioned, you still only have the same No of channels as your TX. You might use it for eg where you have run out of channels but want to have a crewman steering a fake wheel or tiller at the same time as you operate the rudder, or anywhere you might want 2 things operating from one
    stick
    (or switch) simultaneously . Could save a bit of complicated wiring or running 2 boats (one from each

    ), you can park 1 and run the other and vice versa or if you have good coordination, run 2 together (might put a clip up to demo, - have one of the MTB and Maiami running together). JB

    Mixing throttle and rudder
    I did this, well sort of, by using the settings in my transmitter, which at the time was a spektrum DX6i. You use dual rates, and exponential settings, I would imagine most modern 2.4 sets have this feature. In simple language, dual rates (D/R) will limit the throw, so by experimenting you flick the switch, and all of a sudden you have limited the throw of the rudder, flick it back for slower speeds and you have full movement. Exponential (expo) nulls the centre
    stick
    movement, and is generally on the same switch, so it makes the

    (rudder) in your case less sensitive, so easier to use at higher speed. Just remember though, most transmitters and receiver have aeroplane terminology, so, if your rudder is right

    quite a while since last update
    it been quite a while since the last update, holidays, work, sun shine etc all got in the way we have done some amount of work on the model in past few months mostly around the running gear and some electrics Made up a platform on which all of the main electric components will sit on, these include the 2 batteries (6 volt for the steam and lighting) 7.2v for the motor. also on the platform will be the smoke/steam generator, motor, ESC, receiver and at the back the Servo for the rudder. platform made out of MDF and sealed up and then re-enforced with wood strips before fixing the platform inside the huil (permanent fixing) did a "Bath" test to add ballast to the hull as you would imagine that it rides high without anything expect for the platform/batteries and paddles. used Car wheel weights as ballast as you can go done to the nearest gram with those as well as
    stick
    on on where needed. once ballasted (not fully as need to put superstructure and deck fittings on before the final a ballast glues (epoxy) the platform, into place (with the ballast under it) we can still put extra to the sides and bow/stern worked out where the Servo is going to go, fitted that to the rear of the platform and used 2 rods to goto the rudder arm added 3 switches to a small shelf on the platform, these will be the main ESC/Motor Power switch, one switch for the steam and 1 for the lights. Also ensured we can get to the 2 battery leads fore charging Added the Navigation lights (and wiring) to the wheel boxes as well as wiring up the small set of lights we have in the engine cover. as we are looking at a removable deck (so the whole thing comes off rather then just sections of the deck)on it if we need to get to the stuff like battery/motor etc we can. looking for a solution pointed me to look at the metal clips that are used to hold car speakers into place in car doors etc, basically a slide on spring clip with a hole one side and a grooved hole the other to screw into. drilled the hole in the deck where needed (8 holes in the main deck and 2 in the stern for the rudder area.) drilled holes in the GRP platform on which the deck rests, clipped the metal clips to the hull/desk rest, i have glued some small metal washers to the top of the deck to protect it then we can basically screw the deck to the hull (and remove) without damaging the deck or hull and we are screwing into metal clips and and pulling the deck to the metal clips next thing to do is look at fixing the wheel boxes to the deck, the a way of fixing (but being ale to remove) the house house if needed. then lights and wiring of as we are looking at getting lights to the wheel house as well as a few other places at the same time putting other the deck fittings (Mast, work/life boats) etc once all that done a final ballast, tighten all of the various bolts/screens, charge battery and test sailing (could take a while as working on this slowly)

    Hi Pete, "I have wired them the same polarity because I use a dual ESC so I can just swap the wires over for one of the motors." Hmmm!

    Fitting shafts and motors
    I have spent the last couple of sessions preparing and fitting the prop shafts, mounts and pump plate. First was to prepare the wood profiles, paint with sanding sealer and then prime them. They look a lot neater sprayed grey than just plain ply wood. I checked the two motors and found that the suppressor was not of the correct value. I removed it and replaced with the normal 47nf capacitor across the terminals and 10nf from each terminal to the casing. I then connected the wires to the terminals. I built the assemblies, fitted the motors and placed then in the hull. I then inserted the shafts and connected them to the motors via solid connectors. I prefer solid drive connectors where possible as I believe this should reduce vibration which is often introduced through universal joints. When I was happy with the alignment, I glued the shafts in place with Acrylate. I then fitted and glued the water intake pipe also with Acrylate. Next came the pump plate. This plate also has the rudder servo secured to it. After assembly, this was also glued to the hull. Next job was to fit the rear deck support and the bead on the outside which will eventually hold the rubber fender strip. The pencil taped to the flat
    stick
    at a distance of 12mm was used to mark the outside of the hull similar to marking the deck support line before. It was now time to prepare the two deck levels. Strengthening braces of ply wood were fitted all around. This has resulted in quite a strong unit. The instructions say that the fitting of the decks is next. I think they have forgotten all of the working features of this build. If the decks are glued now, there is no room for fitting in all of the gadgets. I will wait until I know what is required. Next time I will start the preparation of the cabin. This part contains most of the fire monitor servos and piping, radar and search lights plus general lighting. Very busy.

    Fitting the Rudders
    There are four rudders on this boat. The design for these is a vast improvement on the Aeronauts Pilot Boat I recently completed. The first stage was to drill all of the required holes in the hull. These include two for the anchors, two for the prop shafts, one for the water inlet tube and four for the rudders. As this is an ABS hull moulding, drilling is not usually too much of a problem but due to the cost of the model, I decided to protect the insides around the holes with tape to decrease the possibility of cracking. I start the holes off with a 3mm drill and then increase to the final size which in this case was 4mm, 6mm, 7mm and 4mm respectively. I gently filed around the holes to get a nice slide fit and correct alignment of the tubes. The deck lies on a support rib which will later be glued around the inside of the hull. The instructions highlight the build of a simple device which will hold a pencil at a height of 7.5mm. A pencil is taped to a straight piece of wood of about 30cm long with a suitable spacer in between which was 3mm in this case. You can then place the
    stick
    to contact both sides of the hull and then draw a constant line at exactly 7.5mm down. Simple but effective. This will form the height guide for the deck support. This line was also continued around the bow of the ship which will form the bulwark later. The next job was to prepare and glue the side supports inside the hull for the rudder tube support board. Next job was to glue the support board in place. I did not notice at this time that the support board had quite a bad bend in it. The bow was upwards which resulted in the two centre tube alignment inserts being above the end of the tubes. The solution was to glue the two middle alignment inserts under the support board instead. A little awkward but the result is good. The rudder tubes were now fitted and glued to be water tight with Stabilit Express glue. This is good for water tightness. I painted the four rudders matt black and then protected with Lacquer. Although the instructions state that the rudders should be fitted and set up at this stage, I have decided to leave this for as long as possible to avoid damage. The next job is to fit the twin motors and prop shafts. This is a job for next week.

    Nice work, looks great and runs really well. Have you thought of using twin ESCs on the outboard motors and converting the left
    stick
    (elevator - mode 1 set or vice versa for mode 2 ) to twin throttles. Most TXs are easy to convert, just a matter of removing the centering spring and making another ratchet plate for throttle use, - then plug your second ESC into the previous elevator plug on your RX . Would make your maneuvering easier in tight spots with a long narrow boat (plus adds to the scale effect.)

    Brushed to Brushless upgrade
    ".....brushless motors the main question is speed controller as I would need forward and reverse...." Simple answer. You can get reversible brushless ESCs. However, watch out, as boats are a minority interest and many cheap reversible brushless ESCs are designed for car use. These may have a 'braking' feature, which means that the controls work like this: forward
    stick
    = forward backward
    stick
    = motor braked quick forward and backward again = motor goes in reverse which is optimum for cars, but cumbersome for boats. A proper boat designed brushless ESC will be fine, as will be a cheap car one where you can turn off the 'brake'. RNinMunich recommends the Quicrun series of Chinese brushless ESCs, but of course products change all the time. So check that the ESC you are after is reversible, and has a 'no-brake' setting.... Rather more complex background explanation. This is my understanding of how one particular 'brushless' system works - there may well be other technologies out there... : 'Commutation' is the process of switching each coil in an electric motor on at the right time to get attracted to the nearest magnet and off when it passes the magnet, so that the armature will rotate in one direction. In a brushed motor this happens mechanically, and we don't need to worry about it. If you want to know a bit more, get a Taycol motor and start reading papers like this: http://what-when-how.com/electric-motors/commutation-electric-motors/ In a brushless motor, commutation is done by software inside the ESC. So the ESC is essential to a brushless motor - it won't run without one. What the software in a brushless ESC does is start the motor with a pre-programmed series of activations of coils. Once spinning, the software detects the generated back-emf as a magnet passes each coil, and uses this to work out the motor speed, timing, and hence which coils to activate next, depending on the throttle signal. Obviously, this happens very fast. If the motor went round slowly, the generated back-emf would be very low, and the ESC would have difficulty detecting it. So a typical brushless motor has a minimum speed which is quite high compared to a brushed motor. In a sensor motor, the ESC can be much more precise about timing because it reads it off the Hall-effect sensor. It can also run at much slower speeds. But the extra kit, and the low production levels mean that these are going to be more expensive motors. For a brushless ESC the starting process, and the reversing process, are much more complicated than they are in a brushed motor. In each case the software has to try to detect what the motor is doing and adjust the timing to get it running in the right direction 'blind', with possibly odd feedback from the coil back EMF. For a brushed motor, the ESC just reverses the polarity and the mechanical commutation automatically applies a force in the direction you want. The result is that brushless starts can be a bit jerky, and brushless reverses need 'setting up' with a process of signalling from your transmitter or using a program card. Since cheap brushless ESCs are often turned out with little documentation, making them reverse can sometimes be difficult for an inexperienced purchaser.

FPV Mini Digital Video Camera - about ยฃ6 Eachine RC832 Boscam 5.8G 48CH FPV Receiver Combo - 5.8Ghz Tx and Rx - about ยฃ14.80 7 inch Professional FPV Aerial Photography Monitor For Ground Station - about ยฃ17.50 FPV-Pro-DVR-Mini-Video-Audio-Recorder - about ยฃ11.30 Plastic-FPV-PT-Pan-Tilt-Camera-Platform - 99p! I also got an extra
    stick
    - about ยฃ10, a nice plastic box - about ยฃ25(!), and various connectors, switches, etc. The box contains a gel battery for the video, which can power the main R/C transmitter down the connector line - that's what the buttons and voltmeter on the panel are for... Note that the video transmitter runs hot - most of them seem to - which is fine on a drone, but thermal control needs some consideration on a boat. You can see a little heat-sink that I added.... P.S. Oh, and you'll need to arrange a 180 deg servo for the panning... P.P.S. You might want to consider a clover-leaf aerial. That enables what they call 'circular polarity' transmission, which is really useful for drones when the transmitting aerial is performing contortions in the air. For boats, a vertical aerial pumping out vertically-polarised waves may suffer from 'bounce' off the water surface, which turns the reflected waves horizontal. But these are very cheap anyway, and can be experimented with - a bit like different propellers...

    Transmitter Mode 2
    Hi Doug. I have the centre brushed motor on the LH
    stick
    , separate from the brushless which are on the RH. The LH side to side is now the rudder. The article is by Glynn Guest and is in one of this years magazines. It is called something like Modes. Sorry cannot be more specific as the mag has been passed on to other enthusiasts. Enjoy Malaga, should be ice free by now!

    Transmitter Mode 2
    Hi Doug, I have now introduced the ELEVON function on my twin, independently controlled screw models. That puts both motors on the RH
    stick
    (up/down) for simultaneous speed control and LH/RH differential operation for side to side. Tried to explain it in more detail in a recent Brave Borderer blog update. It is also covered in a recent Model Boats mag article. With twin, independent motors find it so intuitive that I like it. Previously had one motor on LH
    stick
    and the other on the right. Found them difficult to synchronize and then steer accurately. Pity my only tests are on the bench as no sign of ice free water here yet. Will report water tests in due course Rowen

    Transmitter Mode 2
    Hi JK, Mode 1, Mode 2? Pooh pooh! I have the German branded version of the i6, also a Spektrum D6 and a Graupner MC-10 40Meg set (for my subs๐Ÿ˜‰). I use a simple convention on all of them. Throttle and rudder are both on the right
    stick
    , channels 1 and 2 respectively. ALL aircraft special functions and mixers are switched OFF. Connect ESC and rudder servo to the corresponding outputs at the RX and away you go. Regardless of which Mode the TX thinks it is. This means that I can control the boat with one thumb. Leaving the other hand free for the special function pots and switches, or the Bierkrug๐Ÿ˜‹ I sail at the Ostpark Lake here in Munich, sitting at the edge of the Biergarten on the bank of the lake ๐Ÿ˜ See pic of my usual corner. My TX can be set to either Mode 1 or 2. I left in Mode 1. Mode 1 or mode 2 doesn't matter, unless some sets have the self centring
    stick
    built in on the left. Even these can be swapped over to the right. Or use the left thumb for navigating! Only minor irritation with this setup; on all the modern 2.4Gig sets designed for the fly boys, is that on switch-on the TX still demands that the throttle,which it 'thinks' is left

    , is pulled down or it won't boot โ˜น๏ธ Safety feature for aircraft motors! No chopped fingers๐Ÿ˜ฎ Haven't found a way to switch this off yet. It's embedded in the firmware.๐Ÿค” Cheers, Doug๐Ÿ˜Ž

    Transmitter Mode 2
    Which mode you use is purely personal. I use mode 2 for aircraft use and mode 1 for marine. Normally there will be one
    stick
    with a ratchet for throttle, this can easily be modified to spring loaded.

    I think your Tx is the same as my Turnigy i6 and they only have spring loading on one

    Wheel Boxes and deck holes
    Forgot an item on the last update, I fitted the pipes and ladder to the 2 funnels. This week:- My dad did a load more work on the wheel boxes, mainly adding the "steps" and portholes to the boxes. Cutting thin steps, a touch of Gel superglue to pin in place and then wood glue to secure it in place. found an issue with the 2 boxes not being 100% matching and "straight" so to speak so a bit of messing around to get each step to fit. Once all the steps fitted and glue dry, the undercoated and painted with a number of top coats of a cream colour. we did not fancy trying to cut/drill holes in the 4 side boxes for the portholes, so purchased some plastic
    stick
    on portholes, painted them a brass colour, painted the glass black and then stuck them onto the side boxes. we cut the 3 holes in the deck for the engine cover, and both the front and rear funnel mounts. lined the holes with wood so that the mounts and engine cover fits over the raised ridges snugly thus giving us a form of waterproofing as well as access holes for the battery and smoke generator. Made up the rear Capstan and front anchor winch (not pictured). also cutout the remaining rear deck section to go over the servo and rudder area. finally dry fitted all bits thus far to give us an item as to how its going to look.

    Turnigy Standard 9x transmitter
    hi what mode do you have the radio set ie glider /heli/prop? as it is this that sets the use of the switches, i have a 9x my self and purchased mine for the same reason as you as was using 12 channels for one of my tugs using all 8 channels plus a 4 channel switcher on the right
    stick
    . you are best setting the mode to prop (will see plane icon on screen) to give you best use of all the switches and then you will have use of three switches as i had lights on one, radar on second and water pump on third. hope this helps
