    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.

      Really nice job with your catamaran, i like this...

    • Cristian Rougier > David Boulanger August 21, 2015 at 7:57pm

      Hello David, and thank you for your answer.

      Catamaran is a bait boat, and i only need for this use; from coast to 500 meters sea in to leave the hooks.

      I don't think to run a race with this.


      I really like the hull, durable molding plastic, i need to fix some filtration, but i don't like the electronic and motors (check the motor on attached files). I can't trust on this.

      For this i'm trying to rescue this.

      Because i'm starting from coast, and the waves are a little big, i'need more speed.

      I work with quads and fixed wings, px4, mission, etc, but never with a boat, for this i'm asking about 
      good practices.


      Thank you for your comment and i wait your news,

      Regards

      Cristian

      Water cooled brushless motors would be a good start.  It will be a bit of work.  I think when you refer to needing more speed you mean more power.  That hull is going to just push a lot of water at speeds over 1.5m/s.  Mine will do almost 3m/s but at a very high amp draw.  I can run at 1m/s for probably 7 hours and it just glides through the water with very little wake.

      Regards,
