I love an Aziz model, sadly got rid of mine many years ago and it does pain me to think of it even now.
Great to see your progress though and I love the concept of keeping it light above the waterline, I like a chunky fixture and fitting but always have been weary when I see others plonking masses of brass and white metal fittings up top.

Looking forward to seeing more.

Been looking for deck fittings made with injection mouldings but no luck. Shapeways have  cranes but winches are not right, made some more out of styrene .

What kind of thing are you after? they could be 3d printed I imagine if they are common enough.

Hi Have looked at printers, still thinking about the resin ones. Some parts are difficult using styrene. Another 2 deck fittings made.

Hi Tugcowboy  Tried casting , mixed results with JB weld perhaps tubes were not warm enough .  Will have another go to make the drums. More weight removed from above the waterline.

Hi
I made MV Celestine. She had all white metal fittings. I cleaned up one of each fitting to make a master. Then recast all in resign. Results over 1.5kg reduction in weight.
If I was you use what you have has a master.

Is cost the only reason why manufacturers haven't switched over to injection moulded plastics? White metal above the waterline to me is a disaster waiting to happen all that weight above the waterline.  I want to sail the boat in all weathers not just flat calm conditions. Been looking at Turkmodels, they appear to have done away with white metal. The next boat may be the Scottish fishery protection one.

Bought a resin moulding kit to see how it compares to Jb weld. Its clear, will see if it takes paint if not another try. Google search gives 2 options , spray primer into mould or mix a pigment into the resin. Fixed the cutouts in the rear deck , both sides are the same now. Some more white metal for melting down for ballast .

Test run in Loch Lomond, boat wants to sail in circles when both motors are set on 100% ( full stick via switches, no rudder input as i was not using the sticks) . Fitted a gps to check , rudder looks ok might be mismatched motors even if they are the same type. Flysky do rpm sensors , another issue is battery life is poor, after hour the telemetry was showing the boats battery at 9.6 v under load.

Going round in circles solved. Voltage to motors from the battery , one speed controller output 9.6v and the other 11.3 v.  Though my Radiomaster 16s had a faulty stick , or internal pc board. Going to look at a brushless set up.
