I’m planning to run a bunch of these underwater without any further protection. Will let you know how that goes. The question is how long they last v. their very cheap cost.
Well, they don’t really need any special waterproofing. That’s why we use brushless motors instead of brushed. Just stick them right in the water and they should work. But putting some anti-corrosion stuff on couldn’t hurt!
