    How To R/C the Scott Brodeen Disney NAUTILUS

    This first video finds a customer -- under my kind and thoughtful direction -- being taught how to drive his RTR Disney NAUTILUS model.



    As time permits I'll post a bunch more video that chronicles the kit assembly, propeller gimbal mechanism, and how it all went together.

    I would love to see that David. This will be my next build sometime in the future:)

      Dave, is there any way to make the original design planes function to control the submarine?

        You can make them work mechanically, of course. However, Mr. Goff, as well as Cheney Bonestell (two very influential production designers specializing in SF related hardware illustration) had the mistaken idea that hydro/aero surfaces surrounded by a strake would effect useful lifting forces.

        However, in a very turbulent fluid flow -- which an exceptionally low aspect ratio surface (such as a strake or rocket stabilizing fin) is subject to -- you can't get any useful moments out of a control surface in that environment. Only with the most modest of angular displacements between centerline and fluid flow will surfaces embedded within the strake produce forces that are predictable and of significant magnitude.

        Bottom line with a control surface surrounded by a strake: The greater the angle of attack; the sloppier the fluid stream becomes; the less effective becomes the control surface.

        Goff's planes won't work in the real world.

        However, changing the thrust vector (gimbaled propeller) does.

        (Note that Simon Lake's planes, from which Goff got the suggestion, are in the open slip-stream, not hidden within strakes or other fixed structures).

          Oh , its obvious, from watching the video, that your gimble design works well. Nice! I was just wondering, so that, If one of those "Design Purists" shows up and says, HEY.....................................

                Speaking of which, I saw a movie the other night called, "Grey Lady Down". Charleston Heston and David Carradine(kung fu dude). Anyway, they showed the DSRV rescuing the good guys. I couldn't help but notice that the prop was fixed but the thin nozzle surrounding the prop tips was itself on a gimble and thats how its steered, pitch and yaw. I wouldnt think that such a narrow Cort Nozzle, for lack of the correct term could steer it, but I guess it does.

                  Ill review the movie tonight and get the names of the real subs used to make the movie. The underwater scenes must have been filming a model sub that looked like the Skate class, just like in Ice Station Zebra. Charleston Heston certainly wasnt a Moses in this picture. He barely made it out of that sub with his skin. Thanks to the DSRV and the Kung Fu Guy. LOL!

                    What an awful, awful, movie!
