    Very nice indeed sir. Are the ballast tank and dry sections built by you?
    IT TAKES GREAT INTELLIGENCE TO FAKE SUCH STUPIDITY!

        Very nice! If you have room, I'd recommend some foam up top and ballast down low to try and counter that torque roll that you have. The 31" Nautilus models are pretty heavy so there's not much room for foam, but put as much as you can as high as you can with some ballast in the keel in order to keep it stable...

          You can also try a little less pitch on the prop, moving the torque curve higher up the RPM band.

            Unfortunately, I know, but I've never built propeller........ I'll try (although I do not know where to start)


            The problem with foam/ballast is solved

              You start with a pair of pliers (sorry, Romel). That things white-metal, right? Twist away.

                Go with Bob's suggestion of adding foam and weight first, though.

                  No, it isn't in white metal.
                  the prop is brass (raboesch)

                  I've already reduced the diameter but it isn't sufficient.

                    Can you retro-fit the white metal propeller?

                      Raboesch props are already quite low in pitch (roughly 1:1) so I wouldn't tweak that any more. Sounds like it's just too much top weight.

                        No I can't.

                          Well, before all that, do as Andy said: more weight low, more foam high. That will increase the metacentric height of the beast, making it more stable about the roll and pitch axis.

                          I have spoken, so let it be written! (crack of thunder)

                            If you're out of room inside (its a bit of a tight fit for some people), you could also try putting some clear plastic fins on the side of your rudder. Your video makes it look like the model lists to starboard under power. If you have a horizontal fin on each side of your rudder, have the port side one pointed downward and the starboard upward. In that way they may help to fight the twisting moment generated by the prop torque. The good news is that the action will also be proportional to the propeller thrust, as is your torque roll, so it may work well!
