    Your "Jimmy Carter" is really an awesome build Steve! Wish I could make SubFest and see it in person!

      Thanks Rob. It is turning out good so far. Very impressive to see in person for sure. Sorry you can't make Subfest. Once I get the mechanical fit and function of the hull sorted out there will be a significant amount of sanding and filling to do mainly because of its size but it will come together. Last year at Subfest I had my Thresher with nothing more than primer on it and now it's done.

          Seawolf runs split stern planes in a tips and flaps configuration. The inners are the smaller flaps like the original and with the outers, the whole tip of the chord rotated. The Trumpeter model in
          s inaccurate in that the planes go full length.

            Good to know. Not quite sure I am following you though. Do you mean like this or something different?

                Are the flap and the tip actuated separately? Do they move differently?

                  Thank you for the diagram. That is what I thought you meant but something in my brain was saying NO! For real?!? Did the flap and the tip work in unison?

                    As far as I know, yes. I never got to drive a Seawolf, so I am not familiar with if they could be operated independently or not. I suspect they are similar to how the split planes work on a Virginia.

                        I don't know this for sure. But, if you want to dampen out foil-roll and snap-roll induced banking (sexy looking but a big ship control issue), differential use of those outboards would be of some assistance, even though their moment arms are short. Such use would put a hell of a 'knuckle' in the water -- so much for stealth.

                          Ok. Decision time... I gotta noodle on this one a bit.

                            Dave with the win on pics.

                            The newer ship control systems could handle it, but i do know that the dihedral surfaces do dampen out the roll and snap phenomena so no need to operate the split planes as such.

                              David, did you use a single pivot rod for the surfaces or two? I see what looks like both ways in your pics. The finished model has two but one pic of the raw parts appears to show just one and a support 'tooth' or whatever it's called extending from the fixed horizontal plane?

                                You're spot on, sir. The larger 1/96 model had the room for independently operated stern planes -- one set inboard, the other set the full-flying outboards, each set with their own operating shafts. The smaller 1/144 model only had room for a simplified arrangement which ganged the inboard and outboard control surfaces on a single operating shaft -- a cheat.
