Best bang for the buck. This a great combo, It includes everything you need, Motor, ESC, Program card and High Torque Servo.
Servo is High Voltage, it should operate at 7.4 V, so you may connect it directly to 2S lipo battery, and orange cable (signal) connected to receiver.
ESC has Deans connector to battery with a 15 cm long cable, and it has cables with soldered connectors for the motor with good length (22 cm)
It is recommended to upgrade firmware for ESC and program card before anything else.
