hi ya J that looks like an Mtroniks speed controller in the pic - does this one have the button on that you press to set it up? because I know what you would need to do is set your trim in the neutral position for the throttle and then go through the procedure of switching on the transmitter and then the receiver and then pressing the button on the speed controller so it recognises where neutral is. I believe some of these Mtroniks are something like 100% rpm forward and something like 75% rpm in reverse. If this idea doesn't work you could always swap the wires over on the motor. (NOT ON THE BATTERY) 🤓 Chinee smokey come out of speed controller if you do dat 😲 John
Whilst I am not new to boat modelling, I am new to r/c and I’m confused about an issue I have. You can see the setup in the images. Everything works fine, and testing the boat on the pond; I was very pleased how she ran. The issue is this: if I set the trim switch (bottom right on transmitter image) to reverse, the rudder works normally. If I set it to Normal, it is reversed. If I set the throttle trim switch to normal, the throttle is reversed, and if I switch it reverse, the motor runs a full throttle, with the joystick in the neutral position! All the other trim controls are in the neutral position, as in the image. I have double checked all the wiring, and would really appreciate some help on what I am doing wrong.
Building the paddle boxes was remarkably easy, once the 1mm ply had been steamed for bending. I decided to build the boxes first and make sure the paddles fitted inside later, the idea being that all this would come apart for maintenance should it be necessary. (it usually is!). There are few models to be found on the internet to use as reference and hardly any images of the original tug. And to confuse matters, PS Iona also existed as a passenger ship, as well as tug, and looked a bit different. The superstructure is really simple and quick to build, with some more planking! Am liking planking small areas now. The funnels came from some scrap plastic tubing in the garage... just the right diameter too, a lucky find. These will screwed in place from below once I have the other funnel parts made. I plan to run the tug on batteries rather than steam, as I am a relative novice to model boat building. The whole deck will be fitted with 1mm ply as a base before... more planking! Before all this is glued in place, I thought it best to water test the ship first and see how much ballast I am likely to need.
Today I did a full test of current smoker build, it went very well, nice consistent smoke, very visible. I used just straight a mineral Oil, type sold in Pharmacies. I chose not to use the baby oil again because it had too much of an odor. See video attached. I ran it for one hour, it stays consistent and there was no build up of heat, tin stayed cool. Check of the heating element and wick showed no damage, no build up of any kind, very clean. When I get a chance, I will put a multimeter on it and test the draw so I can fuse it properly. Thanks for you interest. Joe
Michael, Anything can be done but I strive to keep things simple. Like a dipstick for level and fuses to protect the electronics from getting out of control. I generally end up with double fuse protection as well. Best to just get in the habit of keeping an eye on things. The fluid drain is very slow so I don't foresee a real issue with that. If an alarm was used, you still need to get it back to shore before it .......... Cheers, Joe
Hello, Could not resist starting an experiment with an all metal container. This is a small tomato sauce tin can out of the pantry. First time I tried soldering tin to brass and it is very easy, with flux, to do. Will run test on both smokers and publish photos. As noted, it is a good idea to add a fuse between the batteries and the powers switch as these heaters tend to draw 2 amps or more, be careful with wire gauge as well. Danger of fire.... Joe
The navigational lights and the smoker still need to be final wired with a power switch for each. The amp draw on the smoker is about 2.2 Amps as measured with my meter, so I intend to use a 2 1/2 Amp Fuse. Will probably just use manual switch rather than remote just to keep it simple, we will see..... Cheers, Joe Joe
My batteries arrived, could not find locally so ordered through Walmart online. Two - 6volt 4.5AH, wired in parallel to give me 6v @ 9AH. Used inline fuse, prior to switch, then on to the esc, a Dynamite Tazar 15 T marine type. On/off switch will operate from outside so hatch will not have to be removed. Had some real nightmares trying to program this esc! Setup lights would not come on, went through all procedures, slept on it tried ecpvery website, tried again today, nothing. I was about to look into a new purchase, THEN LIKE MAGIC.... I mistakenly switched it to my zBrooklyn Tug mod on th TX which uses the same esc, and it startled me with the motor running and rudder moving. Everything worked great. So I just copied all of the settings into this build on the TX. HAPPY NOW Photo shows the mass of wires that allows me to shift the batteries for final ballasting, they will be tucked away neatly as build is finalized. Regards, Joe
The HobbyKing ESC I’m using has the facility for water cooling and as it will be in an enclosed location without any free ventilation it seems sensible to utilise this feature. To keep the water circuit as short as possible I will put the pickup just behind the propeller and the exhaust on the stern but as the boat has a bulkhead just in front of the stern skin I need to make an access hole through it to allow me to secure the nut on the stern skin. I made a hole through the bulkhead large enough to get a socket on the nut and reinforced the hole with a ply plate, similarly I reinforced the inside of the stern skin where the outlet passes through it. When I was happy that the arrangement worked and I could attach the hoses and securing clips easily I glued and pinned the stern skin to the hull. The water pickup is a standard one that is readily available but it’s supplied with overly large and ugly fixing nuts, the inside one is of no consequence but I thought that the outer one needed smartening up so I put it on a threaded rod and locked it in place with another nut and put that into the chuck of a drill and used a file to re-shape the nut to a pleasing taper….who needs a lathe......😜 I had to reduce the height of the inner keel former as the pickup tube is not long enough to get a good fixing with the internal nut, as the inner keel is balsa I fitted a ply reinforcing plate to spread the load. The last ‘photo shows the location of the ESC, main battery fuse and receiver. The hoses will be secured to the ESC with spring clips throughout. I found that the silicone tube I use tends to kink rather easily if the radius of a bend is too small and I found it necessary to form a tight spring coil around the piece that loops the water back through the ESC to prevent this happening.
Put together a pilot house based on some tugs I've seen. Just freelanced it as I went. I build a lot with styrene so I am used to just cutting and building. I use liquid styrene cement that fuses the materials together. See photo, will trim it out as I mount it, need to add some detail at roof and some Navigational lighting. Put on on 3mm plywood deck, same as hull bottom. The deck is also curved (proper term is SHEAR) and I started to build up some wood edge at the opening. Will sand everything well, then start sealing and priming all surfaces. Made a bracket for the rudder servo mount and an adjacent platform for the ESC and RX. Ordered two 6v 5ah SLA batteries. I will wire in parallel to stay with 6v and get 10ah. I like to stay with 6 volts as I want the motor to run slow like a tug should. Will wire in an in-line fuse. Haven't decided where I will put switch, up high somewhere to avoid water. I will show the wiring once I get to it. This build is going fast because it's a simple design, just what I was looking for. I work on it late afternoons and into the evening while I watch basketball games. About 4 hrs a day. Looking forward to building the hatch and getting some primer started tomorrow. Regards, Joe 👍
Thanks Doug and Donnie tried the 15 amp fuses all went well the boat is ready for the lake. and thank you all for the help and advise during this build over the past year I really don't think I could have managed it without your input. the next stage is going to be replacement of the brass rudders and some work on weight saving and some pic on the RC system. and making a suitable box for transportation. that will kept me occupied till the better weather. So thank you all and have a merry Christmas and happy new year and a good hangover cure and may your god be with you in all your sailing
