Features:
1. Adopting high performance and powerful MCU, more convenient to control and easy to set different functions.
2. Unique circuit design with strong anti-interference.
3. Water-proof and dust-proof, suitable for all-weather condition races.
4. Start mode can be set, with fast throttle response and very smooth speed control linearity. Suitable for all kinds of racing boat.
5. Low voltage protection threshold value can be set.
6. Built-in SBEC, with large power load ans low power consumption.
7. With multiple protection functions, input voltage abnormal protection, low voltage cut off protection, over-thermal protection and throttle signal loss protection, which make the electronic speed controller more reliable.
8. With good high power safety performance, the motor will not start immediately wherever the throttle lever is.
9. The output power will automatically reduced when the temperature of electronic speed controller is over 100℃, and the output power will return to normal when the temperature lower than 80℃.
10. With cycle menu setting, easy and simple to operate. Supporting for remote controller setting and programming setting.

Package Include:
1 x RC Boat Electronic Speed Controller

Note:
1. Please check if the battery polarity connect are right before using in case of the electronic speed controller being damaged. 
2. Please disconnect the battery and the electronic speed controller if not use for a long time.
3. Please don't remove or modify any components on ESC, or it may cause permanent damage or data losing.
4. First time to test speed controller and motor, please don't install propeller and driving gear if not sure the setting of receiver is correct or not.
5. Please do not use broken, short-circuited and over-heated battery pack.
6. Please do not use substandard cables, cord and connectors.
7. Battery cells and servos number can not be exceed ESC standard.
8. Please do not put speed controller in a moist and glare place.
9. Please do not remove the battery when motor is rotating, it will cause huge peak current and speed controller burning.
10. Please install the speed controller in the ventilated place, do not wrap anything around it.
