1Unique powerful high performance processor, users can set the use of functions according to need, support brushless motor, unlimited RPM, support fixed speed function. 2Safety overload protection, superstable throttle linearity, low voltage cutoff, automatic throttle off when the signal is lost. Abnormal input voltage protection, low battery power protection, overheat protection, low power protection when throttle signal is lost. 3Fast throttle response speed is fast, stable linear speed, start mode can be set, can be used for fixedwing aircraft and helicopters. Low voltage protection threshold can be set, builtin SBEC, large working power when starting the steering gear, low power consumption. 4Good safety performance, no matter where the throttle lever is in the controller, the motor will not start when the power is on. The circuit design is exquisite and the antiinterference ability is strong. 5When the ESC is operating, the output power is halved when the temperature reaches 100 C. When the temperature is below 100, the output power automatically resumes.Support the operation setting of all controllers and the setting of the programming panel. After power on, set the alarm sound to judge the working situation. Item Type: ESC Material: Plastic, Electronic Components Color: Blue Type: 40A ESC Continuous Current: 40A Burst Current: 50A Battery: Nixx Lipo 5-12NC 2-4Lipo BEC: 5V / 3A Size: Approx. 27 x 52 x 11mm / 1.1 x 2 x 0.4in User Programming: Yes Applicable for C3536 engine Suitable: for Fixed wing remote-controlled aircraft Connection Cable: Can be welded directly or connected to the motor by a high-quality connector Always use new connectors, which must be carefully soldered to insulated cables using heat-shrinkable tubes The maximum length of the battery lead must be within 6 inches 1. Motor wire solder controller 2. Appropriate solder connector for battery conductors 3. Isolate all solder connectors from heat shrinkable tubes 4. Connect the connector "R" to the receiver 5. On the throttle channel, the red and black wires from the controller are connected to the red and black wires from the battery pack, respectively. 1 x 40A Brushless ESC 1 x Manual 1. Please allow 13mm error due to manual measurement. Thanks for your understanding.2. Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.3. Always put safety first when using the product.4. Connected to the battery electric motor and ESC may accidentally start, thus posing a serious hazard.5. We recommend that you remove the propeller while operating.6. When flying a remotecontrolled aircraft or other remotecontrolled vehicles, do not fly over other people or near people.
