just ordered the hull from R2Hobbies In Hong Kong, with postage It came out at A£42. The hull has a number of holes In both the top and the bottom on the port side, these go Into a chamber that Is sealed off from the remainder of the boat, and vents through the back. Allegedly, this makes It self righting If you capsize It. the plan Is to fit a 115mm strudder with a 4mm shaft, and a Hobbywing 3600kv through a Hobbywing Seaking 60A ESC, culminating In an X345 or an X438 by Octura. I will also use a Water cooled motor mount. It Is a case of awaitng delivery now.
