Features: 1. All devices are original, ensuring high quality and stable performance of electrical fit. 2. Multiple protection functions including abnormal input voltage protection, low-battery voltage protection, overheat protection, throttle signal loss protection, etc. 3. With three start modes: ordinary start, soft start and super soft start, compatible with fixed-wing aircraft and helicopters. 4. Throttle can be set, compatible with various remote controls. With smooth and exquisite sense of speed, first-class linear speed. 5. The maximum speed can reach 210,000 RPM (2-pole motor), 70,000 RPM (6-pole motor), and 35,000 RPM (12-pole motor). 6. Start protection: If the engine cannot normally be started within two seconds after the throttle is started, the electric adjustment will shut down the engine, and the throttle can only be restarted after it is put back to its lowest point. . (Causes of this may include: Poor electrical harmonic contact connection or disconnection of some motor output lines, propeller being blocked by other objects, and speed reducer teeth being clamped, etc.) 7.Temperature protection: When the working temperature of the electric setting exceeds 110 degrees Celsius, the electric setting will reduce the output power for self-protection, but will not turn off the output power, only for 40%. Full power on further to ensure the engine is powered to prevent the machine from falling. After the temperature drops, the electrical adjustment will gradually restore full power. 8. Accelerator signal loss protection: When the throttle remote control signal is detected to be continuously lost for 1 second, the electric setting begins to reduce the output power. If the remote control signal is restored during throttle power reduction, throttle control is restored immediately. Advantages: In case of instant throttle signal loss (less than 1 second), the output power will not be cut off immediately; If the signal from the remote control is really lose for a long time, it is protected, but also not immediately turn off the output, but there is a gradual reduction. The power out process gives the player some time to save the plane, taking into account safety and practicality. 9. Overload protection: When the load suddenly becomes too large, the power will be cut off, or restart automatically. The increase in load is usually motor jam. Specification: Condition: 100% Brand New Item Type: ESC Material: Electronic Components Color: As Shown Size: Approx. 13.5 x 10.3 x 1.7cm / 5.3 x 4.1 x 0.7in Package List: 1 x 80A ESC Programming Description: After powering up, the throttle hit the maximum, successively 2 hear didi sound, 3 didi sound drip, 4 sound didi cycle drip. To hear accelerator minimum on / off sounds 2 is to learn the accelerator; hear 4 minimum sounds on / off synchronous throttle on and off switch, and hear 4 minimum sounds on / off brake on and off throttle.
