Hydro & Marine Maritimo Catamaran (Single motor build)
The inspiration for this layout was from a Maritimo Cat that was built by Ray Schrauwen, whose project puts mine to shame.
Design parameters.
My budget did not stretch to twin motors so decided on single motor set-up.
Motor is Feigao 14XL (but have options of using 10 or 8 winds)
Esc is CC 125, which I already had in my Syncron.
Rudder , I wanted to go with an in-line rudder, originally opting on a MHZ Hydro In-Line Rudder but was not able to get this due to stock availability.
So I decided on a speedmaster rudder which I then modified the bracket & strut to make almost in line (offset by 1/16 inch)
For the dive shaft I opted for 3/16 flex cable to cope with any increase power in the future.
Batteries
My original choice was to start with NIMH cells 18 or 20. But when I first tested the boat the Intellect 3000 cells I had would hardly get the boat up on the plane.
So next step was LIPO , I now have two 3S thunder power extreme packs that will be connected in series. (I can then run these in parallel in the Toysport Syncron should still be fairly fast but give long run times)
Step 1 - Built structure for mounting Motor, Servo receiver & reciever battteries
I liked Ray’s set-up for mounting the Motor and servo in a single framework, I was not able to get hold of any Carbon sheet or similar so opted for using Aluminium to build the frame (light weight was not a primary concern as I had read that this size Cat can suffer from flipping if to light)
Also it was easy to work with the Aluminium.
Step 2 - Modify Rudder and Strut
Modified the brackets holding the rudder so the strut was close to being in-line, it’s actually off set by 1/6 inch.
Step 3 - Battery placement.
I’m still working on the battery placement and how to secure them. I have made some fibreglass brackets, which are epoxied to the hull and am currently looping velcro though these.
So far from tests best performance is with the batteries as far back as they will go.
