    The hull is SUPER light. I don't have a scale that can weigh this light, but my Renegade rigger with motor and CC Phoenix 25 ESC, & RX weighs roughly the same as this hull & HW.

      Cool, that's a good reference, I had one myself some time ago...
      Do you think it needs some reinforcement somewhere?

        The XL will not fit because of the angle of the motor mount, but an S will, maybe an L, but I don't have one to test fit.

        The hull will not flex anywhere near as much as the blizzard, renegade, and Graupner silver bullet. I may want to pad the nose a bit, just because I may hit something with her.

          Sorry for the dark pic!

          The coupler set screws are mm. the wire? I don't know the size, but I'll find out tomorrow when I get my caliper.
          I have both dial and digital calipers ... you can borrow the digital or the dial type (as this is is better - Brown & Sharpe) top of the line for calipers! Or if you want I also have Starrett mics to get a more precise measurement.

              how wide is the inside of the tub? will it fit most lipos?
              How about the coupler and the screws, are they mm or imperial?
              Is the shaft a .68 or one of the german sizes?
              The wire is a .56
              the boat hull w/ HW weighs in at a whopping 18.2oz

                You might want to change that .056" to a .078" if you are going to be running 4s through the hull.

                  Danny, what are you power schemes...ESC..LI-PO etc. Any of the XL motors are a bad choice for that hull size The S and L are better dependant on prop and your final power scheme. Neat looking rigger

                      Should be a screamer on the lenher. Too much power?? What prop and ESC ?

                        I don't have an ESC planned yet, but I plan on the V937/3 prop

                          What is this "too much power" you speak of?

                          Diego, I was getting worried about you posting the 4s packs in your boat.

                          Good thing you decided to go with 2s.

                            Gunnar had the record (93+mph) now Brian has it with a 1512
                            w/ the 1920/4 or 5.
                            just an FYI

                            J.M. I think he was planning in using the packs in parallel...

                              The 1512's are cheaper than the 1930's
