            As boaters suggested. Need a stronger boat bottom. Tested with one with the rear 55% of the bottom and transom made with double fiber layers, equivalent to 600g/m^2. Weight increased by 90g. Feel that the bottom is now very strong. The hull weight is now 850g.

            Believe that can make the whole bottom and transom with double fiber layers and can maintain the same shipping cost. Estimated hull weight should be 880g.

                Hello boaters,

                Since the bottom made with 600g/m^2 fiber. JetChopper30 hull specification changed to:
                Weight(new): 850g(1.87lbs)
                Bottom and transom shell thickness(new): 2mm
                Deck and hatch shell thickness: 1.4mm
                Length: 760mm(29.92inches)
                Width: 230mm(9.06inches)
                Height: 129.5mm(5.1inches)
                Deck to keel height: 100.6mm(3.96inches)
                Resin: polyester
                Fiber: MAT, 300g/m^2 for deck and hatch, 600g/m^2 for bottom and transom
                Surface material: gel coat

                The bottom and transom are now very strong. Yet, some sort of rails, connecting rods for the motor mount are still highly recommended.

                Happy rc boating,

                  Those are good improvements; even so the original hull I received was plenty strong. It's generally acceptable to install a transom doubler to better seat the rear hardware so that's not a problem. Using 3/32" plywood for the motor bed is also the simple solution to insure rigidity; also a simple operation. Mine's just about ready to compete in the P-Ltd Mono class at the NAMBA Nationals in two weeks. Should be a promising entry

                                We tested with different RUDDER SETUP. Found that this setup has pretty good stability to turn at full thottle:
