    @Cristian,

    You might want to look at how I installed brushed 540 motors in my RSV catamaran hull.

      @Cristian,

      The gearbox reduced the motor speed range to the speed range required by the size of the propeller.

    I like this hull, where did you get it?

      Hello, and thank you for your comment.

      I purchased the Jabo bait boat 5CG, you can find this on google.

      I like hull, but not the electronic parts and motors.

      Regards

      Mike,

      Short cut to the hull should be below.  I stretched the hull about 5 inches but other than that the drawings are accurate.  No keel as the design is meant for a sailboat not a powered boat.

    You are exactly right.

    Just install gearbox free, direct drive motors + 2 controllers for brush motors

    Motors should be water cooled (heat exchanger made of pipe )

    My 2 racing catamarans look great ( just enter catamaran rc into Google search)

    "RC racing catamaran"  40 km/h max. speed

      Sorry, regarding propellers what are the best?

      Thank you

      Cristian,

      With that hull design and weight you may be wasting your time trying to make a fast boat out of it.  Naval architecture is a very complicated science.  What kind of run time are you looking to accomplish?  Look at the link below.
