Hi Bruce,
First of all, WOW! you got me with that missile launch, amazing! :mad_2: I would love to see that in action.
And is that the HMAS Sydney (AWD destroyer)?! Is she your model, she looks awesome!?
Regards,
Phil

Hi CAG-1NUT,
Looking great, can't wait to see more and with a working missile launcher! Wow!
Regards,
Phil

[quote="DavidP"]I presume these missiles actually launch? in what way do the 2 stage rockets not work right?[/quote]
Well, that depends on which shot. With the first, the 2nd never fired. Another, the 2nd stage blew up like 4 feet from the ship and so on, lol. I also can't find any rocket motors under 1/2 dia. and will likely just stick with my modified mini bottle rockets as they work, most of the time anyway. :-)

i'll be building the floatation device holders for the 8" guns soon and want to get them right; thus what color are the floatation units?

What with all the aerials other items to be added, I decided to build a dolly/boat railer of sorts and a folding ramp to get it into my van without breaking anything or getting poked in an eye by an aerial. Such is the downside of building big.

I now have most of the working features ready. The radars turn, main 8" guns & terrier missiles train, my terrier fire control is also working and ready for Sea-- umm Lake trails. The search lights work fine and the ship's fog horn sounds great. I just need to program chanal 5. It's not a completed model yet; it still needs a working RC helicopter, lots of detailing and what not.

BTW my terrier missiles are still single-stage. My 2 stage rockets have not worked very well yet!
If the weather complies this weekend, videos will follow.
IF you live in Northern Va, and want to see it on the lake, let me know.

Maybe this video will work? nope had to delete

Here's where I'm at with the build and conversion to CAG-2. btw the helo pad came in very handy whereas I was to recess and hide a 3" speaker [ship's fog + other sounds] under it along with 4 mini toggle switches for the radars, search lights, RC radio, cooling fan. I will add a video later.

Neither the Boston nor Canberra had AN/SPG-49 directors. These were Terrier ships and the SPG-49s were a Talos system radar.

Some of the Terrier radars had a base assembly very similar to the 49s but the antenna was drastically different.

This photo shows the Boston and Canberra side by side:

The Boston carried Mk 25 Mod 7 radars initially and the Canberra had the SPQ-5.

Looks like I screwed up! I built and installed two SPG-49 units on my Boston-yup the ones used on the Canbera CAG2 and not CAG1! Thing is I like them better and may redo my ship as the Canberra instead. Whereas doing so will also let me operate a helo from it. I read somewhere that majore difs between the two ships was the deletion of either one 5"DP or one 3"AA. From the photos
(http://en.wikipedia.org/wiki/USS_Boston_(CA-\69)#mediaviewer/File:USS_Boston_Cruiser.jpg) and (http://www.navsource.org/archives/04/070/04070.htm)
I've seen they both had the same number of 5" & 3" mounts? Also how accrate is the 1:700 model of the CAG-2 -as seen in a recent What's New here?
Thanks and will post some photod tonight.

You need to know the length of the specific boat(s) you want to model. There are many similar boats of different lengths.

If you want blueprints of the boat(s) see this link:

Here's were I'm at with the build:
I just put the last deck plank down. Yeah, it's not very correct and needs more stain work and whatnot, but it looks good.

I had to make the wacky looking superstructure platform to hold it -it can do so upside down also- so I can work on the motors for the 8" main guns, missiles and radars. The upper bridge is almost done; it's just not in place. As you can see, I still have much to do! Although it's what I call a [i]working model[/i], IE, RC with working missiles, I intend to add a lots more detail.

BTW: in addition to her lifeboats, I want add a motor launch or whatever it's called - the one with the small cabin, but I cannot seem to find any specs or good close-up photos. Any help here would be much appreciated.

I'm still at it; haven't posted any photo lately, whereas , I've been trying to work the bugs out of my electronics. If my problems persist, I may post my schematic for help.

The flotation test went quite well. When tilted until her deck was almost awash, it quickly righted itself.
BTW that test was conducted with a temp heavy and high CG battery, plus 2 6v 7AH batteries. I have since removed the high CG battery and replaced it with 2 6v 12Ah batteries. We were also amazed at how well our DIY props/screws worked. I now have a few servos installed and will, weather permitting, put in the lake again Tuesday and see how it does at full power -12vdc- whereas, the test was at only 6vdc. Photos to come.

Thanks for the concern.
LOL, my first scratch build -in 1/120 scale- was the IJN Yukikaze. It was so top heavy, I had to hang a 5 lb steel bar off the bottom! It almost sank once with my father-in-law at the controls when he crossed the bow of my USS Alaska -no contest here- and almost rolled over! Her decks were awash when it reached the beach.
Thus, I plan to do so floatation test real soon. Whereas the model now has 2 6 volt 7AH gel cells and may get another and much heavier 12 volt gel cell:all 3 are/will be mounted at the bottom of the hull. If our displacement calculations are right, it should be quite stable. Else will I'll be building new 5"DPs, 8" mains and whatnot! I'll try to remember to take some photos of it afloat, perhaps this weekend,

Be careful that you don't put too much weight topside or the ship won't float upright. Your solid wood gun mounts will be much heavier than hollow assemblies made of plastic.

There was one beautiful build a few years ago that was made with solid wood components like your gun mounts. When it was finally put in the water it wanted to turn turtle and that couldn't be corrected. Very disappointing!

Phil

Well it's almost ready for a hull/screws/motors test. I just need to put some 8/32 threads on the propeller shafts and an receiver in it. It still needs much detailing, and the terrier missiles firing system workout, which should be fun. More photos to come soon.

I lost the list of where to buy screws/props for model warships, and haven't had much luck searching the web. I made my own brass 4 blade screws, and thus far, my first 4 are not looking very effective.

Thanks

Ops, found it............

HERE ARE A FEW MORE PICTURES. Adding some bulkheads and deck -less planking- and checking fit here. Still have much to add to the superstructure. I plan on attaching on the related gear such as: motors for turrets, radars, terrier firing systems mounted to the underside of the superstructure and left out as one unit. I may also add a pump and float switch to motor compartment if I can't get the ends of the screw shafts above the waterline. Stuffing box suggestions welcomed. More photos to come.
