R/C Naval Combat

I plan to pick up the graf spee hull from Bob on Thurs. This will give me my old cruiser back as thats what i started with was Tommy's old Lutzow. I will be in need of a 3.5oz bottle but all other parts are here. This boat will be built over the winter and will battle in 2009 built to treaty rules. This will give me two treaty ships and two iirc ships so i can battle either way.

John, Mack found a source for small bottles and light regs too.

Hey Jay the Lutzow does not need a lightweight Craig is having problems getting her to weight with its gear, I plan to use my heavy just to add the extra weight.

OK, who knew??

I sure did not until Craig started to put the gear just sitting in the hull and it came up light, he will most likely hve to add ballast to get its weight right.

So, mine ought to be just about right, wieght wise, seeing as i will probably bui;ld heavy, having little idea of what to do. Do you guys suggest that concrete crack filler for waterchanneling?

I used the self leveling concrete sealer in my Lutzow. Worked great! It kept the weight down low in the hull. I think it only used around 14 ounces, so weight isn't a factor. My ship ended up at 13 lbs even. The ship barely rocks in a turn. :)

Here is some pics of the concrete waterchanneling ...

There was a little leakage under the wooden waterchannel rails, but the fix to that was to stick the wood into the hull and seal the gaps with RTV.

very cool, i look into this.

***Edit: i might just do like 3/4 length of the ship, so that i dont get into the complex bow and stern.***

Boomer, just make sure you get the right stuff!!! I bought some up here in the Great White North but it wasn't the stuff that was used down there in the South. Well, I did a test to check the drying time and after 2 1/2 months, it wasn't solid yet!!! I couldn't find the same stuff here that was used by other guys. Just thought you might want to know,

Look 3/4 of the way down this page Visit this site and you will see a few pictures of self leveling concrete sealant being put into a wood ship. The third picture shows the sealant tube itself which may help you find some where you guys are at. :)

Concrete sealer da! working in a chemical supply warehouse you would think i would have seen it. ok. lets see, second shelf in from the door third from to top marked concrete sealers.
Thanks for the news and I'll see whats there.

Yeah, I saw that tube in another post but was unable to find it here in Nova Scotia. The stuff I bought at Home Depot was made by Stone Mason and is called Concrete Flex. I hoped it would work better than it did, but it took soooooooooooooooooooooooooooooooooooooooooooooooooooooo long to get even a thick enough skin on top that it would not break, I just don't think there is enough time in the off season to have a boat put into one spot and one position so the stuff dries and then do the other side ( I planned on having it sloped into the centre ) and then still have time to finish the boat for next season. Sucks though cause it would work real well I think, rubber water channeling.

I now have a supply of epoxy concrete sealer that cures fast and is easy to work with. I'll do some tests on the old river class hull so i don't right off the good hulls.

thanks mike, that helps. Ill look into it.

i bought 2 tubes of DAP self-leveling concrete crack sealer for the hull, but its gonna sit until i can get the hardware kit, and pump from BC.

Took the Lutzow off the shelf and dusted her off on Thurs. Installed the armour and the water channel as well as the shafts and rudders are in place, made the deck (again) and will have it on by the weekend. ship will be hopfully ready to display at the show in Apr. and will make a good bakup for Roberts this year.

Back up to a monitor, really? Not the other way around?

Boomerboy: The Roberts is a nice ship to run and can out turn almost any ship on the water. I have run this ship before and this is the second one and I think in treaty this is a tough little boat to sink. The lutzow is a nice ship as well but it seems like there is a lot of them around, so rare is a good thing.

Thats cool, just wondering. Im doing a graf Spee right now too, seems popular. Did you make your own hull, or did you buy one?

Hey all a question of about speed. How fast is the Lutzow? I can find several different speeds online although the most frequent is 28.5 knots. When transferring to treaty speed, (ok 2 questions), do you use 31.5 sec, 31 or 32 sec?? Thanks
