Success!
Apart from managing to connect the ESC to the motor the wrong way so the throttle controls were reversed (easily rectified!) the first trip out was a great success.
The water cooling outlet needs to be moved to the stern, the water pump is very efficient but the outlet from the side of the hull looks ridiculous. I need to move the ESC to the port side as there is a slight list to starboard. Now I know everything works I'll experiment with different props and will try a 3S LiPo as I think the hull can go faster.
She looks great on the water, manoeuvres easily, so very happy with the boat.
