For my Bancroft Fletcher Class Destroyer (U.S.S. Kidd) that I have converted to the U.S.S. Hoel DD-533, I used a combination of shot bags made with #6 birdshot that I already had on my bench and paste on tire weights. I used a 2 lb shot bag in the bow, 1 lb shot bag in the stern and a total of 3 lbs of tire weights in the mid hull. I have converted my destroyer to run on 2S 4.0 Lipos in parallel mounted on a battery tray that I installed in the mid hull, which accounts for an extra 12 ozs of of ballast down low to get the metacentric height correct. Destroyers tend to be tippy so getting the port/starboard balance is critical. I had to use about 14 ozs on the starboard side to get the list out. Now the boat is extremely stable at Flank Speed and she rights herself immediately in high speed turns!
My solution: I go to local home depot store and buy steel plates of different sizes - widths and lengths (used mainly for wood beams connections or similar). I stack them then from the bottom of the ship model on each other and connect them with small pieces of double sided tape (Advantage: you can detach them then any time as you need). I use from 1-3 layers of steel plates depending from model and space. I always try to place on first most lower layer as many plates as I can - for lowerest CG as possible. It's also important to level the ship, so it's needed to place plates at the front or at the back depending where are they needed.
I have the 1/150 USS Missouri. It sits higher in the back. I put about 12 pounds close to the motors without touching them. It s good in the front half but sits high in the back
Hey there.. I built my battleship out of cardboard, she's about 1.18m long motors are in the rear i added a straightened tyre iron underneath and add a metal shelf bracket for the keel and some metal bolts to the small fin keels on the side.. Shes air tight waterproofed but can get her to stay upright. Do I need more weight to keep her upright? The hull has 3 trianglar keels.. Plz help me...
I personally just taped them down. But you can glue them in if you never plan to remove them. Since the ships in these videos aren't personally mine, I didn't do a permanent fix
