Feature:1. Product Features: This 50A brushless ESC for model airplane features a customizable startup mode, ensuring rapid throttle response and linear, stable speed control, meeting more needs2. Multiple Guards: Equipped with abnormal startup guard, overheat guard, throttle signal loss guard, and low voltage cutoff guard, this ESC protects your model against potential hazards3. Safe Performance: Regardless of the throttle position, the motor will not start immediately, enhancing the security and reliability of RC airplane work, and you can use it with confidence4. Versatile Programming Options: Support various programming methods and remote control function, this RC brushless ESC caters to your diverse operational needs and preferences5. User Friendly: Easy to operate both indoors and during fly, this RC airplane ESC is a practical and convenient choice for model enthusiasts seeking seamless control and performanceSpecification:Item Type: RC Brushless ESCProduct Material: ABSInput: 3-6S LiPoContinuous Current: 50APeak Current: 70ABEC Output: 5V 4A (Switching Mode)1. Braking Force:When you move the throttle stick to the bottom position, the braking function will be activated. In this mode, the amount of braking equals to your preset braking force.2. Voltage Cut Off Type2.1 Soft Cut Off:After the low voltage cut off guard is activated, the ESC will gradually reduce the output to 60% of full power within 3 seconds.2.2 Hard Cut Off:After selecting this option, when the low voltage cut off guard is activated, the ESC will immediately cut off the output.3. LiPo Battery:If Automatic Calculation is selected, the ESC will automatically calculate the number of LiPo battery you have inserted based on the 3.7V/Cell rule, or you can manually set this item.Note: For 15A, 20A, you can choose from the following parameters: Automatic Calculation, 2S, 3S.4. Cut Off Voltage:When triggered, the low voltage guard function will be disabled. In addition, the guard voltage values for low, medium, high modes are approximately 2.8V/cell, 3.0V/cell, 3.4V/cell. This value is the voltage of a single battery multiplied by the number of LiPo battery automatically recognized by the ESC, or the number of LiPo battery manually set, which is the guard voltage value of the battery. (For example, if the low voltage guard threshold for a 3 cell LiPo battery is medium, then the battery guard voltage is 3 x 3.0 = 9.0V)5. Start Up Mode:This is served to adjust the throttle response time of the ESC from 0% to 100 %. Normal, Soft, Very Soft correspond to approximately 200ms, 500ms, 800ms.6. Timing Schedule:You can adjust the positive timing value of the drive motor. Low, Medium, High are respectively 5, 15, 25.7. Drag Brake (DEO):This can be adjusted between Enable and Disable, default is Enable. With this enabled, you can achieve better throttle linearity or smoother throttle response.8. Search Mode:After selecting this option, when the throttle remains at 0% for a set time, the ESC will drive the motor to beep as a reminder..Package List:1 x Brushless ESC1 x Programming Card2 x Protective Sleeves1 x User ManualNote:The default throttle range of this ESC is 1100s to 2000s (double propeller standard); calibration of the throttle range is required when users start using a new brushless ESC or other transmitters.
