I am new to this forum and have a few questions about an ROV that I will be building this summer. So my first question is about thrusters. I was wondering if I need to waterproof dc motors in order for them to work underwater? If I need to what would be a good way to waterproof them? My final question for now is if use dc motors in my project how many Rpm’s would they need to spin at and how much torque I would need in grams. The ROV I am building will use the same frame as the seafox. It will roughly weigh between 5 and ten pounds.
Thats all for now,
