    Amazing collection! That’s my 43 MB and the event was held in the Southern California foothills.

      Tub test went great. I got the motor control dialed in with the ability to pivot and hold position in a small space. Electronics box was bone dry so on to foam placement and ballasting. I plan to place the foam on the upper hull to keep things clean. She is currently a sinker but should be an easy job using a plastic tub in the garage.

        Were the propellers useful?

          They will be. Currently testing with the printed versions. I just had to see how efficient they were.
          I need to sleeve the shafts since I have 1/8” in the design and the props are 3/32. Simple step down using brass.

            Last bit of work on the electronics box. Going with a 2s 5000 to start and will add a cell if performance is too low. Foam is placed in the upper hull so time for a float test and ballasting.

              You could bore out the props David sent to 1/8. White metal is relatively soft. You could do it by hand using a new 1/8 drill bit.

              Make it simple, make strong, make it work!

                I don’t think there is enough meat but will do a test on 1. Easy to sleeve, just waiting on an EBay order to get started.
                They look to be a nice fit.

                  Final tub float test. I have 1/8” of roof above the water for a good starting trim. Using Velcro in the corners to do the fine tuning. Radio box is complete and I was able to get the 900mhz antenna pretty vertical and the 2.4 at the highest point of the pressure box.
                  Lake test this weekend.

                    The prototype Wet Nellie was printed in 1:12, cast and layed up in fiberglass. If the 1/8 printed model is a success, I’m going to make a single engine hot rod out of the fiberglass hull.

                      As Q would say, "Do try to bring her back in one piece."

                        Fantastic work. Love the Corgi toys too. I still have mine from when the movie was new. So you made a mold of the 1/12 scale and then made a glassfibre body/hull? But the 1/8 you are using the 3D printed hull directly? In the last photo with the Corgis and the carpenters square on the large model the back window looks more curved. Did you change it?

                        Looking forward to the lake test!

                          That is correct. The 1/12 is glass and 1/8 is resin printed. You could drive a truck over the glass boat. The hope is to make a high power ultra hydrobatic model for the pool. Rolls and surface breaching kind of stuff.
