I built Deans Solebay and had no problems with the way she sits on the water, mind you I did pack a lot into it. I have two Astec ESC, two 7.2v NiCad packs side by side, a mylar speaker under the funnel, three Astec sound generators fwd, plus an amp, and all the rc gear as well. Even then I put extra weight into her to ride at the proper waterline. As an original Battle class she does not have the top hamper that Aisne has, especially the 965 so far above cg.
Lovely model I congratulate you.
As an aside I got thrown off the Aisne, whilst I was an inquisitive apprentice in HM Dockyard Portsmouth, while she and Barrosa were awaiting disposal me and my made went on a self-guided tour, it wasn't approved of by the officer standing by the ships. Grumpy s*d, lol!
