    Hi,
    As for the old plan on the sb Kitty, I think it's quality only suitable for building a small toy for fun. So - I am also building it for this purpose. The plan is simple, practically without the necessary details.
    In addition to her, I have scratch- built 2 large models in 1:24 scale - the Capricorn model, according to the modified plan of H.I.Chapelle, very similar to the sb Giralda, and another model according to the Lady Daphne plan (1:28).
    I am attaching a copy of my plan for Capricorn here.
    I can recommend here pls>

    Hi,
    I use the wiring with V-Tail mixer according to figure 1 on my Lulonga quarterwheeler model.
    Even though I have the option of mixing in the transmitter, this connection seemed simpler to me. In addition, the options and method of mixing in the transmitter did not suit me.

    Hi,
    I am giving some examples here.

    here (fig 1) you can control the model with only one stick too(e.g. put throttle to channel 3 , rudder to channel1(ailerons)
    I really don't remember where I found this on the net
    I finally managed to find a comment, probably from RC Groups
    I found it interesting,but there were difficulties in placing the document on these pages.
    Tom
    Due to several people asking similar questions, some diagrams to help make things easy to understand.

    image 2, having a BEC enabled ESC and a seperate battery pack,
    you will notice here that the red wire in the tri-color servo lead falls short of the rx, this is to symbilize its removal from the plug.Β don't snip the wire carefully remove it and tape it back, that way you can still use it if you have to.

    using a seperare battery on a bec esc can be used if your rx happens not to have BEC ability because its old, or you need to add a touch of ballast, why add lead when your ballast can be made to work for you.

    Image 3, full BEC system one esc one motor.
    BEC means Battery Eliminating Circuit, this means that the main battery that feeds your Electronic speed controller, (ESC), also feeds power to the rx though some in-built step-down regulator circuit. again this diagram depicts one propeller, this is usually used where space is an issue, such as in a converted lindberg trawler or other small model. Another issue is weight, such as racing boats where the additional weight of an rx pack may cost a second or two a lap because your boat is hauling a few more ounces than it needs to.

    Image 4 Full BEC system with twin motors, one esc.
    one esc and two motors, wired in parrallel, with a fuse off each motor. not everyone has multi channel boats, some people still have 2 channel AM systems but may want to run more than one motor in their boats, this is the easist way to do it. wiring in parrallel means that should one engine stop working because of binding and so blow the fuse, (fishing line wrapped around the propeller is a usual cause), the iother motor should still be able to bring the boat home, though the operator will probably suffer some handling issues. using series wired, where the electricity flows through one motor then through the other would have just one fuse, one stalled motor would pop that sole fuse and so leave the boat in need of rescue.

    Image 5, twin escs with bec esc's and rx battery.
    This sort of layout is often found where the transmitter has on-board mixing, and usually found on larger models where space isnt an issue, such as 1/35th scale tugs and bigger boats, up to something like a 1/96th scale tico or burke type warship. the single battery may be because you want the physical space inside for fitting of working features, gas powered bb guns for the RC combat people, or things like working sirens, or your battery may be quite large to start with anyway.

    Image 6Β is identical in laypout except it has two batteries in parrallel to double the run time or the main battery supply is also being used for lights etc

    As with any BEC equipped ESC, if you are using a seperate battery packΒ remove the red wire to prevent damage to reciever

    image 7, mechanical esc, one motor
    yes mechanical type speed controllers, or relay type like those by Electronize may not have a BEC system, so need to have a seperate battery supply for the RX to work,
    image 1, twin esc's with a mixer
    if you have no on board mixing on your radio and wish to make your twin screw boat perform like its real counterpart, you can do this by adding a V-tail mixer, this device normally found on aircraft links the two esc's, in this case BEC type such as Proboat tornado 50 or Viper15's with their bec wire removed from the servo plug because you are using a seperate power source.
    to do this, you are best having more than 4 channels on your radio set, both tx and rx, a typical set suitable for this is the Futaba 6EXA or Hitec Optic 6, or a Skysport 4, though you may have other preferences.

    Fusing
    You may notice on the diagrams, there are more than 1 fuse, the one on the motor side of the esc protects the electronics within the esc, so should your motor start to over-amp the esc, it will fail before the esc gets damaged. however should your esc develop a fault, the fuse between the esc and battery should pop, protecting the battery,Β especially useful if lithium polymer type batteries are your power source

    Hi,
    not worth talking about - I wish you a quick recovery.
    I have been a member there for many years, and I must say that you can find there almost anything you can think of.
    I have my Lulonga quarterwheeler model there and several articles about the construction of paddlewheels. On my model, I tried using slanting padllewheel leaves. It has perhaps a little better maneuverability. But I see their use mainly only with quarterwheelers. I don't think it's useful for classic paddlewheelers and sternwheelers...I control the model with one stick - both speed and turning using the V-tail mixer (+ another stick for the rudder, which has low efficiency due to its location between the wheels)Β¨
    I added some pictures of my Lulonga
    I modified the transport trolley from the skeleton of a shopping bag.

    On the other hand, there is a simple program for calculating the load, which I have used several times. It can of course be used for materials other than lead. It is possible to select a suitable bulb shape in it, the output is possible as a drawing in 1: 1 scale.

    Hi Nerys,
    I must say that I am fine, even though the situation around me is quite tense, the number of patients is increasing sharply from day to day. I haven't been to the water with the model since that first sailing in June.
    Over the summer, my wife employs me in the garden, and when I had relatively time for models, the wind didn't blow at all.
    To be honest, I didn't want to drive a sailboat model just by using an engine.
    I was looking forward to a nice autumn, but now it's been raining in one piece with us for a week now ... and in 14 days the pond in the park will be emptied.Then the bell and the end of the fun..
    The article I wrote for our RC Revue about Gundalow was happily published - at least something positive.
    greetings

    Hi,
    It is also due to drought and high temperatures, the trees have little sap and cannot defend themselves.
    Now I'm just waiting for better weather so I can go with the models to the water.
    It is said that it is a normal summer, but we are somehow not used for such summer, that it also rains in the summer here...

    Hi,
    the problem with the RC gear solved himself,the device works..
    Martin, gundalow is a working ship before all,sailing with the tides, similar to Thames sailing barges in London.
    It can be seen from the pictures that a rather reduced area of the mainsail is used on the original of the vessel, no possibility to use next sails.(pictures are from the internet ).

    Hi,
    I have a permanent problem with the wind - there are tall trees around the lake in the park. Now I do not have the opportunity to go with the models to more suitable water. When I was at the dam Vyrovice in South Moravia with Capricorn, there was a large body of water, but the wind still didn't blow...
    The river Bečva, which flows through the city, usually has little water, so it is not possible to let a sailboat with a keel there.
    As for the steamer Ned Kelly, unfortunately, I have no video from its operation. After a long break, when I tried to get a more suitable boiler (the original boiler from Wilesco is really only for toys), I finally sold the model to my friend. For such models, it is necessary to have at least a lathe in the workshop equipment, which I do not have, and I will not buy it anymore ... it is a bit too late for me.
    Originally, it was supposed to be just a model for testing a steam engine. But when the money spent began to exceed a reasonable limit, it was more advantageous for me to build a straight model of an Australian steamer. That's when I got books and plans from Australia from penfriends. The only question was the name of the steamer - my friend Dick wrote to me ... why it couldn't be Ned Kelly (a well-known Australian robber). I thought ... why not, in the end ... so the steamer was named Ned Kelly.
    The last pictures - this is our river Bečva, when it doesn't rain, there is little water in it, and a very strong current after the rain.
    It is not suitable for launching models ...

    Hi,
    The meteorological forecast said today that the sun will shine here for 3 hours after lunch. So I took the model with confidence, loaded it on the cart and drove to the park. The wind was very weak, so I had to help the engine several times. As usual, every first ride of my model ends in disaster. It ended with a jammed rudder and the RC equipment terminated service. Fortunately, it was by the shore, so I didn't have to go into the water.
    On the other hand, the model sailed quite well even in such a weak wind.
    Next time, maybe it will be better ...

    Hi,
    thanks for the rating. I really like the older sailboats and steamers with high smoking stacks , from a time, when the ships looked like ships and not shoeboxes.
    I do not dare to build complex models of ships, rather I am looking for - from today's point of view - some unusual or generally unknown constructions - as in this case Piscataqua river gundalow. I just hope I can still build some models of ships..time flies very fast for me ..
    In addition, the translator from Uncle Google is still correcting my writing, and if I don't pay attention for a while, he writes nonsense.

    Hi,

    There is finally enough water in the lake in the park, but I have to wait again.

    Yesterday I was preparing my model Caprice (Piscataqua river gundalow) for her first maiden voyage. It's raining and the weather is damned cold, almost like March, not the end of May.

    Nicer weather should appear hopefully next week. I'm quite curious how the model will behave on the water... hopefully I will finally see.

    Pictured all my models - Caprice, tsb Gusty Cat and tsb Capricorn (all in scale 1:24)
    at the back on the shelf is my quarter wheeler Lulonga.

    Greetings

    Tom

    P.S.
    In the end, I replaced the purple foresail on the Gusty Cat model ..

    If you have any links to the modeling site, I recommend - please browse through the offer of their topics .. yourself best know what you are interested. Excuse me .. you can also find many articles here too , on Modelboats => How to .. and this is where you should start.
    I also recommend the reverse procedure .. enter the topic you are interested in - and Uncle Google will print a series of links ... search and answer ... if that's not what you're interested in - try to ask in another way .. when I started, it took me at least 3 days before I got the right answer to my specific question ..
    Beware - you always have to take into account that Uncle Google has a "classic" education, and its technical knowledge is ... in many cases - say - minimal or curious.

    I think those articles will certainly be of interest to experienced modelers - you can always find something interesting..
    Ahoy !
    Tom
