I live in Korea. My first system was a mess. It’s very weak. But it starts again. We will replace all the parts again. So I ask for your help. Compare sss 500kv motor, 64m impeller water jet system, or sss 500kv motor and 100m impeller thrust direct thrust system. Which system has a strong propulsion? I want to hear it from experienced people. Also, which motor and ESC can produce the strongest thrust in the water for me? Please recommend including battery.
