GoolRC 2-4S 30A Brushless ESC Motor Speed Controller Remote Control BEC ESC for Fixed Wing Aircraft 450 V2 Helicopter Boat FPV F450 Mini Quadcopter Drone Without Plug

Specifications: Item Name: Brushless ESC Color: Black Type: Without Plug Voltage Range: 4V-16V Batteries Quantity: 2-4LIPO (4LIPO does not allow BEC output) 2LIPO: 4-5 Miniature steering engine 3LIPO: 3-4 Miniature steering engine Size: 45*24*11mm Weight: 27g Setting Method: 1. Turn on the transmitter and push the throttle to the highest (FUTABA series transmitters need to use the throttle channel to select REV). 2. Connect the receiver and motor. 3. Turn on the ESC power supply. If the transmitter is normal, the following sounds are available: (If is a long B sound and then without sound again, please check the transmitter throttle channel reverse setting.) B B: indicates LIPO automatic protection BB BB: Indicates NIMH/ NICD automatic protection BBB BBB: Indicates brake selection (When there is no operation, all sounds will continue to loop until there is an operation request.) During the sound loop, when you hear the settings sound you want, pull the throttle to the lowest position quickly at the first syllable that prompts the sound. At the same time, the motor will make a very sharp sound to confirm. At this point, if there is another setting, quickly push the throttle to the maximum, and you can make the next choice. If the setting you want is complete, wait 2 seconds, the motor again emits the appropriate battery protection to determine the sound, and confirm the throttle position, then you can use. LIPO automatic protection has only two protection voltage protection points, 6V and 9V, which can be used without a fully charged battery. NIMH automatic protection is calculated according to the actual number of batteries. Each battery is set to 0.8V. In order to accurately determine the battery voltage, please fill the battery. Package List: 1 * 30A Brushless ESC

• Safe Power On Function: When the power is on, the motor will not be started immediately no matter the throttle rocker is in any position to avoid personal injury.
• Throttle Stroke Calibration Function: Adapt to the difference of throttle stroke of different remote control, and improve the linearity of throttle response, with smooth, delicate speed control feel and first-class speed regulation linearity.
• Strong Anti-Interference Capability: The power input terminal adopts the ultra-low impedance large-capacity electrolytic capacitor, which greatly improves the anti-interference ability.
• Temperature Reduction Function: The output MOSFET power tube is equipped with an independent heat sink to reduce the temperature rise of the device and improve the system's high current working capacity.
• Independent Voltage-Stabilizing Chip: The single-chip microcomputer adopts an independent voltage-stabilizing chip to avoid power supply interference caused by BEC load change and improve the working stability of the single-chip microcomputer.
