RTV silicon - as a tip, take extra time to shape the foam to fit closer to the hull, avoiding air pockets if possible when you make the final placement.

If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub. -

got the ballast kit for the gato from caswell. not for sure where the 6 pieces go. On bottom or sides. I'm thinking bottom and foam on the sides. All so not sure where pink foam goes. The 6 pieces are black with what looks like bird shot in it.
Please let me know. Thank youComment

Start with three of the weights, situated in the center. And, yes, they go in the bottom of the hull. The foam, is equally spaced longitudinally on the sides of the lower hull. The trick is to place the top of the foam even with the boats designed waterline.
Make your initial installation take pictures and we'll guide you in for a safe landing.

put foam in hull. the weights are just sitting ther for now. need to know if is alright to grind them down a little. wtc woun't fit all the way down the way they are. Here' picsComment

Got all my foam in and my weights epoxyed in. Hopefully weather permiting going to my sons house and use his pool to balance the sub.Will let you know how it turns out.Comment

would like to know the reason for balancing sub below surface instead of at the water line on surfaceComment

Because I said so, damit!
You people!
first you want to work out the amount and longitudinal location of the foam within the hull, with the ballast tank full, so that the boat at rest is on an even keel and just an inch of sail sticking out of the water. Proper submerged trim.
Then, with the ballast tank dry, you will move foam vertically to achieve the correct surfaced waterline.
Done! Happy trails! Kiss the girl. Go home happy.

Very nice job you've done on the model. neat and clean finish. Don't sweat the small stuff, adjustments to the weight and foam distribution may be needed from time to time anyway. It's not an easy task, but you've done good. Enjoy!Comment

David, Thanks for the reason on balancing.
Anuci, Thanks for the comments. Doing the best I can. Only have built warships and frieghters, subs are a hole different breed.Comment

been gone for a while. back working on sub again. got a little problem. when I turn everything on for the first time everything works fine. when I turn it off and then back on the elevator and ballast do not work. I leave it turned off for about 10 min then
turn it back on everything works again. Everything is hooked up right and full battery. It has the adf2 and lipo guard in it. any ideas.Comment
