Feature: 1. 2‑In‑1 Brushless thruster, one ESC can carry two brushless motors, suitable for RC boat. 2. Can drive two motors at the same time. There are two modes. The first mode is that the two motors move at the same speed, and the second mode is that the two motors turn at different speeds for mixed control. 3. The ESC forward throttle and back throttle speed is 1:1, forward 100 percent throttle, the back is 100 percent throttle. 4. Electrically adjusted waterproof level IP‑X8, up to 100 meters of water depth. 5. Wonderful and practical replacement accessory for RC boat, directly fitment.
