Martin,
It is a difficult topic. I bought a copy of the mag containing the free plan and so I am free to use if for my own use in any way that I wish, provided I do not make any commercial gain from that use. However, publishing the plan on this website, or anywhere else, whilst not providing me with any commercial gain, does potentially deprive the original publisher of income, and that is the issue here. At least that is my understanding of the rules. Graham93 ▲

Just a thought Graham,
How do you stand copyright wise now that you have reduced the original plans to the scale that you wanted. Have you not already broken some copyright rules ? Is it still covered by the copyright.? As you can tell i know nothing about the subject of copyright. Martin555. ▲

There are no measurements on your plan, would you be kind enough to send me a private mail of the plan. I can redraw it on AutoCadLt adding measurements. Ron ▲

Martin,
"Can you give us some dimensions please." It is just over 6 inches long, 2 5/8" wide and 4 1/2" high (155 x 67 x 115). As for plans, I don't think I can publish these as the original plan is from the recent Model Boat Winter Special 2019 and I'm sure covered by copyright. All I did was reduce them to 50% size.

Hi Graham,
Can you give us some dimensions please. I will defiantly be following this as it could be just right for me to use in Big Blue. Maybe you could have a set of drawings that we could print out. I know it is a bit of a cheek asking. Martin555. ▲

Hi JB,
"how about a mini solenoid from a remote sw to make contact for motor on/off rather than a bulky ESC " I have several mini solenoids as well as RC switches, and together they are far bulkier than the titchy 'thumbnail' ESCs you can get nowadays. Or even the guts of a old servo. More than enough for midget boats😊 Alone the weight of the solenoid 🤔 bang goes your payload capacity☹️ Cheers, Doug😎 ▲

Going great guns there Graham. Was just thinking, how about a mini solenoid from a remote sw to make contact for motor on/off rather than a bulky ESC or are you going to come up with some electronic wizardry? A 2ch system would be useful for these small boats I guess, due to the smaller RX size. I still have my AM 2ch boat TX but not sure about a RX, think the last Acoms one was dud. Some of these cheap R/C toys have tiny simple RXs and servos, and solenoids for steering, maybe you can steal one from a local kid😂

So, it seems I am not the only one building a push tug in honor of the coronavirus.
This was a Tugster kit from Zippkits that was a raffle prize and at the Empire State Model Mariners meet some years ago. The kit sells for $29. It is pretty good, wood is O.K. and laser cut parts fit together easily. I am not a kit guy, so much, but I had nothing else going at the time so I thought I'd look at it. I am under house arrest because of the virus. It is meant to be a simple retriever for other boats so I looked at some pictures and started modifying it. I am making it up as I go along. Here's how it looks so far. It will have funnels, maybe a big winch, maybe a kort nozzle. It is 18 inches long, I decided the scale was 1/24 that makes it 36 feet. I will see how it develops. Any suggetions? ▲

Hi Graham,
Attached is a pic of my basic 'oils' kit for various colour rust streaks and black for the wash for dirt and to bring out small detailing more. The pointy brushes for the tiny detailing, useful for my 1/72 crew! Nos 2 and 8 for dry brushing, nos 8 and 10 for the 'wash'. Re acrylic weathering paints; I posted some links to LifeColor Weathering paint kits in Ed's Smit Nederland blog - under 'Re: Capstans'. Also includes some 'How To' links NB Practise on some scrap material first!!😉 ▲

Thanks all for the comments and feedback, especially on weathering. I will have a go at that, but will have to get some suitable paints and maybe a stiff brush or two. Time to have a look on-line. Royal Mail is still delivering although understandably the service is a bit erratic.

Good comments using waterbased paints on weathering. I scratch built hese two little 'O' scale locomotives out of metal, styrene and wood. Painted with acrylic paints and weathered with pastels. Both can be washed off within certain cure limits, about 12 hours. Washing becomes part of the weathering techniques as well. Once I like it, I put a light coat of matte or satin water based varnish over it.
Good luck with weathering and don't be afraid to experiment as Martin says it can be washed and redone. Joe 👍 ▲

Looks like fun Graham - particularity impressed with the way you made the Kort nozzle earlier - and all the other fittings . Tugs tend to have a rough finish anyway because of the life they lead - crew just give a quick touch up to hide the latest ding- so don't think you have too worry . The crew member wont notice anyway.......

May i suggest that if you do experiment then use water based paint and the dry brush method. Then if you don't like what you have done you can simply wash it off again. Martin555. ▲

Martin,
Weathering had crossed my mind. I have never done any, but I have seen some fantastic examples here on the site, including from you. As this little tug is just for fun, it would be a good opportunity to have a go because it wouldn't matter if I made a bit of a mess of it. Graham93 ▲

Ron,
Looking good. I’m confident it will work - eventually 😉. However, it isn’t ever going to be my first choice of boat to sail. I built it to have a challenge to distract from lockdown, and to have something to sail in my test tank as that is the only stretch of water I’m going to have access to while lockdown is in place 😆. I hope to have a progress update on the blog tomorrow. Graham93 ▲

Hi Ron,
If I found the right Traxxas battery on Google, at 3.7 x 1.3 x .67 (94 x 34 x 17) it is too big to fit. The 7.2v is also a problem as the receiver and servos are rated at 6V max. More importantly it needs to fit in the sump which is only just over an inch wide. As you can see, the access hatch is tiny. My new battery has just arrived. It only has 400mAh capacity, but it easily fits. I'll get it all back together over the weekend then it will be bathtime! Graham93 ▲

In my J-502 Billings Kit, see photos, the access area is 2”x 4-1/2” to measure the depth was not available unless I unpacked it all. The battery is a Traxxas power cell. 7.2v NiMH 1200 which takes up less bulk than a 4AA pack.
Would this set-up work well in a Micro Tug? ▲

I did use very fine enamelled copper wire for the LEDs down to the bottom of the wheelhouse. See my earlier post on the Wheelhouse with some ( not too clear) photos. At the bottom of the wheelhouse, I connected the enamelled wire to some thin flexible wires to bring the connections down into the hull. ▲

“Just a silly idea can you turn the receiver upside down and have the connectors facing down.” Not silly at all. 😀 I tried that but it didn’t solve the problem. Once I have the new battery, which is based on 2/3 AAA cells and hence shorter, there may just be enough space in the sump for the connectors on the inverted Rx to fit. Graham93 ▲

How about one of the little flat 4 or 6 channel pico RXs with the connectors at the end? They don't have a hard case to get in the way! It'd be lighter too 👍 Used one in the cramped 'Forward Radio Compartment' of my Type IA sub U25. RX battery slots in next to it - JUST!!😁 Cheers, Doug 😎 ▲

JB,
A mini barge to go with the tug is a possibility. It would make it more of a challenge to have something to pull or push round in the tub. I have been following your airboat blog. Made me wonder about a mini airboat as the next project 🤔 Might be able to escape the tub and ‘float’ round the garden. 😂🤣 Graham93 ▲

Success ! Well done Graham, you need a bigger tub to release the full potential! What's next, - matching mini barge?😁

Exactamente Graham👍
BTW: Got curious last night and went hunting! Found three unused ZN409s and two Microprop servo kits😀 Unfortunately the instructions for building the gearbox were missing🤔 A chap could go bonkers trying to work that out!! The whole shebang must be a good 30 years old. Thinks!! Now what if I .....🙄 Cheers, Doug 😎 ▲

Hi Red,
As Doug says, it shouldn't be too difficult to work out which red and green wires need to go where based on the pinouts for the chip. If there are 4 wires in addition to the throttle input from the receiver, then it will be two for battery and two for the motor. The battery wires will connect to pins 10 and 11 on the chip. Pin 10 for battery positive and pin 11 for negative. The other two wires will be for the motor. Graham93 ▲

Looks really sharp on the water! Reminds me of back in the 60’s, when Revell motorized some of their kits. I built a motorized Long Beach tug and Arizona. Sailed them in our bathtub. Still have them stashed away somewhere.
Of course, your build is way better, because you have full control, she looks great, and you did it on your own! ▲

I think you mean the ZN409 Red,
Data sheet attached. Might still be some around. Might even have some in my 'vintage stash' 😊 Typical ESC cct in the pic. Ref your 'Paddy-made' ESCS- Open one up and post some close up (sharp😉) photos of the insides, top and bottom. Either Graham or myself might be able to work out which wire is which. Cheers, Doug 😎 PS Whadda u know! Found some😁 '94 vintage. A good year😋 ▲

Always admire modellers who understand electronics, a friend made me 3 esc's using the ubiquitous 409Z ? chip used in old servos . Presume things have changed since then as the chip was getting difficult to find many years ago . Paddy has since moved to Oz and now for the life of me I cant remember how to connect them as he used red and green wire for everything which was all he had on hand. Cant work out which lead set is for the battery and which set for the motor - don't want to cook them.............

Well done Graham, electronics is obviously your expertise, a skill which is more and more part of model making.

Hi Graham,
That is great to see your micro tug in action. It did put a smile on my face watching it moving about in that little tub. Ref:- “I wasn't quite successful with the 'build it without buying anything' challenge” In my opinion I think you were successful. As i have discovered it is not easy making something so small fully rc controlled. Martin555. ▲
