Interesting Boat.

Are you open to suggestions? For US Style racing - I am not to sure about a coupe of issues with your design.

Is this a tested hull or just a computer mock up???

Hello,

Intended to adopt the NAVIGA rules. One mentioned that with the RIDE PAD, it is not legal NAMBA mono class. But SD3 and DF33 do have this kind of RIDE PAD.

It is now a CAD model. Will become a real product later.

Best regards,


Leo

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,


Leo
