Thanks HC! This one has been fun to work on. been working on my painting skills haha!

We need an ice maker here too!!
The weatehr has been way out of wack this year, I am on an icebreaker on ice stand-by, and we havent seen ice in four days. normally this time of year we are working 24/7 breaking out ice jams to keep the St. Clair River from flooding. Thats why i got work done on the model!!
I painted the hull, and did some more float testing. apparently paint and glue added enough weight to this little thing that I have to start trimming the inside of the super structure to maintain enough float! The Hull is flat black and the bull warks are gloss, I am going to leave the hull flat black to conserve the few grams that i can!

I did also start building the barge shown on an earlier post. the barge itself is made, now I have to make the house and masts/frames. I think it will look really neat when done!

Cheers, and enjoy those #25's! I am gonna have to make my way down there some time in my life and try one or two of those!

Thanks for looking guys!
The little Losi pack I have powers the micro trucks for a good 15 minutes or so, I think it should do the trick for this little thing (I hope!)
I'll keep posting when I can, I have to get pics of teh barge I am working on for it.

Cheers

I have used onlybatterypacks.com because they are local to me and supply the hobby shop I frequent. I'm sure the same can be found all over.

Well I went to my buddies place and tried it out in the tub. unfortunatelt I can't seal the deck until; i get hiome and link it to my controller there. As it turns out, that open deck edge got submerged and we had a near catastrophic leak!! Luckily i just reached out and grabbed the little thing out before any electronics got damaged...
but i did learn that the servo motor is WAY too slow on 4.8 volts. So I am thinking about alternatives for this now. Either a Team Losi brick, or up the voltage. the problem is the servo is only rated for 6 volts, and the Lipo i want to put in it is 7.4, so I don't know if it will handle the voltage. and I don't want to be changing motors in this thing....

stay tuned

Cheers

Very near completion!!

So big progress!
I have finished all the inner workings and have sealed the decks on. I decided that i didnt want to worry about deck hatches and leaking water into my little project, so i opted to have a nearly sealed unit. The superstructure was siliconed to the deck, and the gear was place in the hull. when i had everything just right, I placed it in the hull and sealed the deck on with silicone. this way I can use an exacto knife and peel it open if anything fails. Where is the charge jack you say?? I consealed it in the stack and wired in a switch using Losi connections. I can turn the gear on and off, and charge it without having to open her up!
I used a nice little Losi Brick with 2.4 Ghz Rx and esc unit from the trail trekker, and a starndard three wire servo. The motor is a high speed unit from the Losi micro trucks. So i cant use it wide open, Maybe some ways down the road I will change that. but it works pretty good for now.

Cheers!!

Thanks Boz,
I did screw the horn down before sealing it. but the ballast is a little off, and the steering trim isnt as nice as i want, So i will peel it up and make some adjustments on it. Took it for a test run, aside from the ballast and steering trim, it works like a charm! now to finish the barge for it and I can start practicing my tug and barge handling!

Cheers

Superb job on this little tug. I really admire your solutions and how you progressed from servo power to an actual high speed hobby motor. Fine work on the paint and detailing too.

I would love to know your typical run-time duration since you are said to be operating it at tug speeds.

Well thank you all for the comments, I was pretty fond of this little tug, but unfortunately, disiater struck!!
I think because the water i was running it in was so cold, the hull must have contracted and seperated from the deck. allowing lots of water in, and it sank faster than anything I have ever seen!!!
I will be going back t the location with goggles and try to get the tug back. but no gaurantees how deep the water is. I am pretty un happy with the loss. it was such a neat little tug!! And it was the very first model of mine that sunk!!!
So If i dont recover the original, I will be possibly making another one. this time a little more water tight...

Cheers

Oh no, what a horrible loss!

I can only live vicariously through you builders who are able to not just dream but make your dreams reality. I mean to say that I'm away from my work bench on a business assignment and can only observe other's build threads.

Here's to success in your recovery efforts or starting over, whichever the case may be.

The Hull and deck separating is all i can imagine that caused it. Now that I built the tug once, I can make it again fairly quick, but thats plenty of money to throw at a project again!!

It has been under water now for four weeks. its probably all rusted and toast... but hey! the recovery will be entertaining on its own!
