Hi Bigford,
Good suggestions - is the Smit Hunter a repainted version of the Happy Hunter? I did fancy doing a version of the "Mighty Servant" which is similar to the "Black Marlin". After the disaster with Fawkes, though, I am rather wary of doing anything that has the intention of sinking.
Seems I will end up doing something tugtastic, though Gry Maritha is still on the list. Looking at the cost of adding extra functionality to the RC system, though, is giving me a little pause for thought. The Robbe system is a nice idea but bl***y expensive and I really do not like the F14 transmitter. I am toying with knocking up my own expandable system to work alongside the main RC, possibly using the 433MHz license exempt modules and lots of PICs - advantage would be that you could have telemetry on the system as well. Cost I reckon, if I can do it would be about £100 including dev tools. I would then use the main RC for controlling the boat and the other system for all the accessories.
