TECHNICAL DATA: 1>Normal work current 15A, Max. current can reach 25A; 2>FET 12; 3>BEC 5V/2A; 4>Auto timing mode; 5>PWM 8K; 6>With function brake on/off; 7>Suitable to work with 2/3 cells Li-polymer, or 4/12 cells Ni-MH. BEC work under 3LIPO 3LIPO or 12 cells NIMh/NiCd MAX with BEC disabled STEP 1: Connect the motor and receiver to the speed controller. 2: Remove battery power from the speed controller. 3: Move throttle stick on full power position (UP Position) 4: Turn on the transmitter. 5: Reconnect battery power to the speed controller 6: After 3 sec you can hear (all sound is 3 times) 6 beeps （It means you are in the programming menu） BRAKE: Brake off / Brake on 7: Move throttle stick on full down position, then you can hear (two beeps) It means the brake is off (one beeps) It means the brake is on If you want to change the break select, you can do step one to seven again. ATTENTION: The 15A/30A brushless ESC is 2cells or 3cell LI-PO auto setting (You can force to select 2 Li-Po by push the selector switch jumper, or pull out jumper select 3 Li-Po) Cutoff Voltage is 5.4V/2Li-Po, 8.2V/3Li-Po The number of servo is converse to the battery voltage, when the battery voltage is high, we use less servos When the voltage is under 7.4V, we can use 4 micro servos or 4 Mini servos. When the voltage reach 11.1V, we can only use 3 micro servos, to prevent the BEC system to be too hot. Price Condition FOB Shenzhen Origin China
