The Ship Model Forum

[quote="Anonymous"][quote="Dave Wooley"]Hi Geoff what you say is partly right. To reduce the prospect of having a "STIFF" ship ballast for trimming is best placed up the side of the hull at a point below the centre of gravity and above the centre of buoyancy the purpose being to reduce the distance between the C of G and the metacentric height. Although the ship is easily inclined it returns to the up right slowly with an easy motion, as a full size ship would do and performes more realistically on the water. All my models are trimmed in this way.

Thank's for explaining this Dave, I will bear this in mind when trimming Marlborough and the Big Victorious :thumbs_up_1:[/quote]

Forgot I was logged out :heh: Victorious

There are rules for building model ships for sailing purposes, and one of them is to keep the superstructure lightweight. That's why most model ships are stable when sailing. The weight needs to be low down, not high up in the model, otherwise it will be top heavy. As long as you keep the weight below the centre of gravity, it will be very stable in the water.

[quote="Neptune"]Agree with Dave, a reason why I'm getting away from the 1/700 and looking for R/C stuff now!

Looks like you guys had fun there![/quote]


We R/C Guys always have fun, and give lots of pleasure to people with out it costing them anything, its like the two young lads when I launched NC for the first time, all there christmass,s came at once, there was no problems, never been in the water and sailed perfect, see the pictures in my artical in feature articals , chapt 14. :woo_hoo: :woo_hoo: :jump_1: :jump_1: :wave_1: :thumbs_up_1: ARH

I also agree with Dave. What's the point of building a 1/96 scale model ship, if it,s just going to be placed on a shelf.

It's like the US or the British Navy, building a ship and keeping it in Dry Dock.

Sorry Les but I have to comment on what you say?. My reaction would be if its got wings then it's ment to fly , if it's got a hull then it's ment to sail.
It's like owning a car with no wheels . you can still tinker with it but it aint going anywere.
Dave Wooley

Sorry for your misfortune. But, I'm a firm believer of static models. If it flys, it will crash. If it floats, it will sink. But, have fun guys!

Hi Guys,
Tim,
Thanks, and you're quite welcome!
MechTech,
I hope you find what/whom you're looking for. Without the folks that love this stuff as much as I do, "this hobby would not be much fun"!
Lee,
Get well, and we'll see you in March!
ARH,
It was fun!
Kenny,
There is indeed more than one way to have fun with RC ship models, and I might be tempted your way. For now, this will do, (including my static "small scale" projects), and that's the way..uh huh, uh huh I like it! :thumbs_up_1:
Steve,
Thanks! Good to hear from you.
Kapitan Joe,
That's the enemy for you! Always stretching the truth! But seriously, you are a very pleasant and accomodating person. A true modeler's friend! Thanks once more for getting me into some dry clothes! I was hoping to get my DDG going for the March 25th run, but I don't see how; with my current TamiyaCon project. Maybe....but...
Klein,
Jolly roger? Roger!

So, There I was 4 feet deep in very murky water. Couldn't see down 2 feet. I was in my shorts, no socks, but with borrowed sandals, (from Kevin), and my favorite BB shirt. I did'nt want to remove it; just because. Each person coaching me from the shore said, "No! It's over there more!", and they'd point six feet to my right, and then 8 feet to my left. I was soaked, and determined, but had no luck. Enter Joe...you know the rest.
Marty e-mailed a motion picture file taken from his cell phone of the Kidd's roll-over. In this 28 second motion picture, there she was maneuvering with a heavy list, then to the opposite heading she would turn...then heel...then more and more...then....over. There was sound with this, "moving picture e-mail", but decorum prohibits the posting of this colorful, but expletive scarred live action, "action scene". After watching this thing over and over, I actually started to laugh histerically. The action was one thing, but the dialog in the background was sooo soo funny. The ship starts heeling hard over, and you hears this, "NASCAR", in the background and then..."Whoa...Oh"......."get it, get it, get it"...and then...F :censored_2: xx!
We'll get back out on the water again. We have to! Like Lee said, they need escorts!
faithfully submitted, Tony Bunch

yes, he was a VERY nice guy and he went way out of his way to help but......As you said Dave; there were many things wrong and Im the one that paid the price. This will be a sore spot for awhile but I will get over it, it only cost me 1100 dollars and his lack of experience cost me. I paid for a running ship and got the Posiden Advneture.... :mad_1:

We will have to give the Americans a taste of our Warship Sailing on July2nd Ron, with a pair of Dukes. What do you say? :thumbs_up_1:[/quote]


THEY WILL CATCH UP ONE DAY GEOFF, :lol_3: :lol_3: :lol_spit_1: :lol_spit_1: :rolf_3: :rolf_3: :rolf_3:

There,s nothing wrong with wood in models, built enough of them over the years , Never had a sinking yet, yes theres always a first time, but if its built right , ballasted right, there should never be a problem, from what you discribe that model was an accident waiting to happen. ARH :lol_spit_1: :lol_spit_1: :wave_1: :thumbs_up_1:

It was a good day for running the fleet, my new 1/96 scale Hatsuzuki ran very well and all the ships had plenty of lake to run in as the water level was very high!
It is always great to see all my friends from the Los Angelis area!
Im afraid it was me at the con of Marty�s new USS Kid when it rolled over, I have a 1/96 USS Johnston myself and it has been running well for over 15 years now so I was not prepared for such a non seaworthy model!
The boat was built to look good and was worth the price paid by Marty but absolutely no attempt was made to make the model stable.
Here is a list of wrongs in the models construction�

1. 2 big r/c car 540 size motors were used making the model too fast and limiting the runtime to only 30 min, this model should run for at least 2 hrs on the batteries we have available to us these days!
I recommend two 380-400 size motors in the 5000 rpm range not the 15000-rpm range of the r/c car motors!

2. A �� or 6mm thick plywood deck was used in the hull making the hull it self a bit top heavy! (I really hate wood on models that go in the water!)
I recommend 1/16� Perspex or polycarbonate or fiberglass or abs plastic deck for replacement, did I mention I hate wood on models that go in water?

3. A fiberglass superstructure was used for the deckhouses and it weighed a ton! About three times as much as you would want and then it very nicely skinned in styrene sheet.

I would both cut out all the walls, decks in the fiberglass, and then cover it in thin sheet or I would just toss the heavy fiberglass and make the structure out of plastics like ABS or polycarbonate sheet.

4. The final and most painful addition of weight to the model was the addition of solid resin cast stacks and 5� gun mounts.
For these things you must do your best to remove as much material as possible from the core of each casting trying to create a 2-3 mm wall thickness, this hard work will be rewarded with a stable model!

The builder of this model is a super nice guy and a very promising ship modeler, I belive that this will be a learning experience for him and in the future, his models will not just look good but will run very well too!
I look forward to sailing with his fleet someday!

Dave

P.S. I do like wood plainking on the decks of warships just not as the deck or any structure for that matter. :thumbs_up_1:

Is that a Jolly Roger on the sunken Fletcher? Hehe, pirates, even with a Fletcher they can't win!! :woo_hoo:
Nice builds, all of them!! :thumbs_up_1:
The cargo ship, is it a Graupner Neptune? I collegue of mine will be building one real soon!


Greetz from Belgium, Johan :wave_1:

YER, TRY PUTTING IT IN REVERSE, :lol_3: :lol_3:

I hope the builder of this kit learns something from this potential disaster. Thanks again guys
MB :heh:

Who said it Capsized? Let me tell you what really happen.

It was an amazing morning on the high seas when my look out yelled. "Schiff gesichtet links vom Bug" (ship off the Port bow). I was called to the bridge and could just make out the top of a ship coming over the horizon. "Mannschaf auf Gefechtsstation! Volle Fahrt voraus! (Crew to battle stations! All ahead flank!) I turned the Z-13 to port 5 degrees and took course 218. We could see soon it was a Flecher class. Hmmm strange to have one way over here? But she did not see us so she was a sitting duck. I closed to 5,000 meters and let go with all Eight torpedos. The Flecher saw them coming and she tryed to turn. First she turned hard to port. Then hard to starboard. I turned Z-13 hard to starboard at this point and orderd."Alle Geschuetze Feuer frei!"(open fire all mounts!) Z-13 shook with the shock as all five mounts fired as one. The Flecher was in a hard to stardboard turn when all five rounds slamed her just above the water line. The skipper of the Flecher then made his second mistake. He turned again hard to port causing the holes I just put in his ship to now be below water. It was to much flodding and she turned turtel.

Well that is how I remember it. Look at the Video I think you will see that is what happen. You can also see the picture above taking from a spotter plane with the flecher up side down and my ship in the background coming around to pick up survivors.

Tony, what a great post! All those fine models, some folks having a great time, and a dramatic and successful ship rescue. Reading this post was better than watching Fox news.
