Here's the video I talked about in the video: https://youtu.be/Dx8P-MDDVEM

In today's video I 3d printed a radio controlled boat using the Creality CR-10s 3d printer. The boat was printed in 5 body sections and an additional 3 hatch sections. I glued the part together using epoxy that seemed to work fairly well, though you really need to install some reinforcement brackets in order to have a solid construction.

The boat is powered by a massive brushless motor (2650kv), that I salvaged from one of my RC cars. With a 120A electric speed controller and a 4S 6Ah battery (16V), it would have all the power in the world!

Almost immediately after testing the boat for the first time I noticed several major flaws. The 5 body sections is only held together by glue, you would greatly benefit with some cross-going spars that would reinforce the structure. As I explained in the video, even though it was no immediate leakage, the water creeps through the PLA. It has mostly likely something to do with the settings used to print all the sections.

There were also a situation with the propeller surfacing too much and not pushing the boat forward. It was unclear if the boat was too heavy or too light and the glue was less than optimal in water.
