TECHNICAL DATA: 1>Normal work current 30A, Max. current can reach 40A; 2>FET 15; 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?s mean the brake is off ∮- (one beeps) It?s mean the brake is on IF you want to change the break select, you can do step one to seven again. ATTENTION: 15A/30A 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
