Design and produce thruster first

It's always the first to design the thruster. We all know the ordinary RC brushless motor can operate underwater, but once you get into seawater, there will be serious damage. So a special manufacturing processes are designed to protect all parts of motor. However, it is a regular process to clean with water after launching, everybody should do with seawater used equipment.

Thruster are completely protected, and we've already brought the thruster into mess production. Esc is located in part of the aluminum part of the installation, and sealed by resin, which can quickly dissipate heat.

 2kg power,  350kv,  30a ESC,  12N/14P,  5600rpm，3s-6s,  10A max . 

We used NI PXI to build a test platform.The ESC in thruster:
