Video. Sorry about the quality, tried many different ways to get it HD onto Youtube like the original but I couldn't.
Finally finished my boat. Thanks sergey for the great model and thanks to Rav3n87 for giving me some great tips to get the boat running good. Final build for all the parts none 3D Printed (except for parts on the back of the boat) ended up being roughly $350. I managed to print my boat (full size 850mm) in two halfs as I've extended my Z axis on my ender 3. I'm running 2 x 3s 4500mah 50c Zeee batteries. I made up a mount for my esc so it's not on the bottom of the boat, where water can get to it. I found the motor mount on here and just edited the size and middle piece where the motor screws on too. All my parts except for ESC came from RC Boat Bitz here in Australia. I also like to use sticky tape on my prints that are over a day long, just in case haha.
