Hi, CLR - Center of lateral resistance - its size is given by the lateral surface of the submerged part of the ship. Lateral. [Latina], surface area - total submerged surface of the side elevation of the vessel-- Center of lateral is important for determining the balance of sailing considering wind pressure. Please forgive me some minor translation problems .. Tom
Hi, some next words yet.. Let me quote some comments from Kimosuby here too.. Still, with out resort to complicated calculations etc most model bargees decide to add a keel. Note; not a fin as this implies a thin item, but a good area of keel. Its position is most usual, on a 1/24 scale barge, with it’s leading edge 3 inches behind the front edge of the mast. It’s purpose is to inhibit leeway, which on such a small flat bottomed hull, is quite large. Visual examination of the barge profile (all scales) shows that this is also the position that the leeboards occupy when lowered, so if it was a good position for the full size barge builders, then it’s probably good for us modellers too. ............ I asked Ivor Bittle too, and he gave me the same advice. he wrote in short ... The location of the CLR should be located approximately on the vertical axis at a location corresponding to the center of the wetted surface of the leeboard located downward approximately at an angle of 45 °- 60° .. if something looks good, then it's good ... Before all --as I can see .. you have to use rule of thumb .. 😊 The Universe in which we live is supremely untrustworthy (Douglas Adams) Greetrings 😉 Tom
Hi, I can reccommend articles by Ivor Bittle too ... late - but still... 2.12 How to locate the fin and the mast of a model yacht on Ivor B.pages ( http://www.ivorbittle.co.uk/ ) On his pages you can find very helpfull articles about Thames sailing barges.. Wishing success Tom
I like Douglas Adams books. ..(and Terry Pratchett too) But I was most attracted to Gusty Cat ... So.. Model of thames barge , build according to modified plans of sb Lady Daphne in scale 1:28 (length cca 1 meter ). it will be again a model with an auxiliary motor, staysail class. I am currently grinding the laminate hull with several layers of putty. It is an ungrateful job.

Hi, do not forget to ask Uncle Google > russian Osa class missile boat .. ..and Wiki, of course. There are two versions of AA armament. For further questions I will answer. Of course, there are some better drawings, unfortunately I do not have these . Wishing success Tom
Hi, very nice model, indeed!! I would greatly appreciate if you put photos your models, also on our website, designed for modellers and enthusiasts of Thames sailing barges .. => modelbarge.info < or > http://barge.homeunix.org/index.php/home I wish you much success in modeling !!! Tom
Hi, sorely I can not put the wiring diagram here, so please look at my album on Rajce , where I placed the wiring diagram!!! > http://tomarack.rajce.idnes.cz/RC_model_Lulonga/ I do not think you got the wrong V-tail mixer, you just need it put to wiring and properly involve. Therefore, I do not use internal mix at transmitter, and even and cannot program it ( therefore, I chose a simple mixer - it performed only simple mixing of signals, in my case Ail and Throttle , no damned programming!!) when connecting of engines because you have to program the transmitter to function properly. (Thr forward - backward) and canal -1 ("Ailerons" - adjust the direction of rotation so that when tilting the control stick left, right engine had more speed than the left engine, and vice versa) I have on Lulonga the rudder separately on channel 4 (on my model has a lousy efficiency), but it can be connected via a Y cable to output Ail, where one branch goes to the servo, the second branch to the V-tail mixer, or you can engage Mix, which lead the canal 1 Ail, a slave can 4 - Rudder - wants this just to try. Of course you can try a mix of programming of the transmitter, but I wanted first and foremost a simple electrical connection that works. Then, if you know how that works, then it is easier to try and programming of the transmitter. This I then used my second model, Thames sailing barge Capricorn > http://tomarack.rajce.idnes.cz/TSB_Capricorn/ At the end of this album I gave examples of wiring and mixes too. I made a simple table, and then tried what and how it works. But it is a control model sailboats. For your model table would look different. It depends on what type of transmitter you have. wishing success ! Tom
Hi, in my model quarterwheeler Lulonga I am using a simple V-tail mixer from HK , each motor has it´s own ESC ,I mix canal 1(Ail) and canal 3 (throttle). the direction of movement I drive with one stick Thr - forward and backward .Ail - left and right. Thr if it is set in the middle position and tilting the control stick to left or right to the maximum to ensure that the motor is rotating against each other, and the ship that turns virtually in one place. wiring diagram > please look here > RC model Lulonga river tug - Posted: 5th Jan 2014 by tomarack http://mdlbt.com/12361https://www.youtube.com/watch?v=iS6F8y60BAUhttps://www.youtube.com/watch?v=tr59Ipalx9g
Hi, I´m back . As I can see .. two-pole socket is designed for insertion of a crystal, ( quartz oscillator prism 35 MHz) not as a supply battery - this also may cause misunderstandings. This arrangement was customary for facilities of 80 and 90 years of the last century with interchangeable crystals. wishing success Tom
Hi, Unfortunately, I do not know this type, and at the net is a range of products from Sanwa - can you write which number sanwa type Rx you have,please? for 2,4 Mhz sanwa Rx has - minus at outer pin, plus at the middle , and signal at inner pin ,(see picture) I think, it is possible for 35MHz too , but it can be a question. As there are some more RX ´s .. so seek the answers for your type. Try Uncle Google with proper question ( e,g, > sanwa receiver compatibility )
Hi, because it is a ship model forum , I would like to add , that after a general agreement the frequency of 35MHz is primarily intended for model aircraft and for ship models this is 40 MHz. Modeler with his boat model to 35MHz in our country considers to be a reckless pirate. If by chance your transmitter operates on the same frequencies, and close air modeler accidentally tuned to your channel, you can cause air model disaster , which is several times more expensive than your ship model.

Hi, this is my last model, thames siling barge on its maiden voyage,October 2, 2016. Preparation for construction of barges - Fall 2013. I have not chosen according to what plans I will build. I bought plans for TSB Lady Daphne, finally I chose but I have other plans. On the Internet I found an information plan barge "Champion class" from H.I.Chapelle. Even though I had prepared and cut out the ribs on the LD (1:28, Loa 98 cm), I finally began to build a "Champion". Loa 110 cm. More photos and a description to> http://barge.homeunix.org/index.php/home < It still remains to be done many details - winches, dinghy, and more. Also, set the the sails just sewn just for a test.Everything I wanted to finish through the winter Tom
As I have this elder transmitter , I needed to set new parameters using t6config. This program worked well on older versions of Windows, up to WinXP. Now I have Win 7, and there were problems connecting to a PC, lacked the necessary drivers. I solved the problem installing CP210x USB to UART Bridge VCP Drivers the address for download > http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpd... (Windows 7/8/8.1/10 Download VCP (5.3 MB) (Default) ) wishing success Tom
well .. I do not use practically the rudder, because in this configuration on my model is practically ineffective, even though is still working on can 4 - Rudder. Due to difficulties in setting internal mixer of the transmitter for 2 motors, I chose an external V-tail mixer; it struck me as easier to adjust.I had always had constant problems with the engines, it turned out at the end that it was defective ESC on one of the two engines.I had to buy two new esc, but from a different manufacturer. The system then worked ok, so I did not need to change the settings.
I have on my model Lulonga quarterwheeler control the direction by changing the speed of individual motors. I use an external V-tail mixer and mix Throttle (can 3) and ailerons (CAN 1). Without problems, one control stick. I think it's more convenient, than mix rudder and throttle.(Rx = HK6A 6 can.) > https://www.youtube.com/watch?v=iS6F8y60BAU if I thr. stick in neutral and lean it to the left or right, the motors have a reverse operation, and the model turns nearly in one place. I use sound mixer module connecting before steam sound unit , on the water just as big a difference can not be heard. You can of course use connecting the sound module with Y cable. This is in my sailing model boat with "iron topsail". I switch it over relay, thus imitating the sound of starting. Tom
I have to say, my first live steam model (sorely the last steam model)was Ned Kelly, aussie type paddleboat model. Aussie paddleboats have as a rule open engine room, it is very convenient for access and control of the steam engine and boiler tuning. When I choose the type Wilesco D52, I chose LPG heater instead of using the tablets for heating. More infos about this model you can find at > paddleducks.co.uk < where are plenty next informations about models of paddleboats. Tom
As to Wilesco steam engine.. What concerns the steam engine,it is but rather a toy. I had a machine equipped with a double geared (total of about 8: 1) , simple paddlewheels about 150 mm dia. and the model sailed fairly quickly, I could not complain. Great pain but steam boiler, which corresponds to more use in toys than the RC model. It has useful content to about 0.2 liters of water, which lasts a maximum of 8 to 10 minutes, with risk of bursting welds. Must then be LPG and the water replenish. The little gas cartouche got heat during operation and it can not be fulfilled again quickly. So I replaced original LPG tank with a large cartouche with a valve of a camping stove, and used the nozzle of a small gas solder. This brought next troubles.. My Wilesco D 52 used a Bunsen burner type, and therefore it is difficult to adjust the unit with new nozzle , and may then fire model. It also happened to me. So it happened... Fortunately, I was expecting a similar opportunity, so I entire engine room and above the ceiling of the superstructure capped with aluminum foil. (This would also recommend to other modelers) I fire quickly extinguished and that there are no damages. It was not a perfect solution, I'd recommend a more professional boiler containing at least 0.5 to 0.8 liters with integrated LPG heating... but think instead about the new steam engine, although the actual steam engine by Wilesco as an introduction to the steam community suits well... It is nearly all.. wishing success! Tom
hi, as I have already answered a similar question on paddleducks, splush the sound of blades, hiss sound is generated electronically steam unit, connected in series with ESC engines (another Lulonga model page 4 there)
Hi, according to my experience (the last time with model Lulonga River steamboat) I would recommend a geared motors with the maximum speed of around 150 rpm for Graupner paddle wheels Ø 140 mm. I use a simple external V Tail mixer - throttle for speed, and mix ailerons for ESC. I can so with a single stick to control both speed and direction. The rudder for my Lulonga model is inapplicable , as to classical the steamer ,the rudder will surely have better efficacy. On my first live steamer Ned Kelly(australian type, wheels mounted on a common fixed axis), I had only controlled the rudder, the model was quite handy;rudder but was somewhat larger.On a boating exam, I used substitute wheel from plywood (graupner wheels I got up later).The model was 115 cm long (o.a) Wishing success Tom
RC model Lulonga , control with V-tail mixer (1.channel -Ailerons and 3.channnel - Throttle) with only one stick (thr) Model of quarterwheeler Lulonga.Smilar ships sailed along African rivers, were built in the UK, France and Germany.Usually they used to be smaller paddle steamers with a little draught.
