4-9 Cells NiMH or 2-3 Cells Li-Po
1) For 4-6 cells NiMH or 2 cells Lipo: You needn’t change the fan combined with the ESC;
2) For 7-9 cell NiMH or 3 cells Lipo: You must change the fan combined with the controller because
it cannot work with such a high voltage, so please choose a high voltage fan or supply the fan
from the receiver (+5V); (*Note1)

[BEGIN TO USE THE NEW ESC]
1. Connect the ESC, motor, receiver, battery and servo according
to the following diagram
“+” and “-” wires of the ESC are connected with the battery pack, and
#A, #B and #C are connected with the motor wires. The “SET” button
is used for programming the ESC.
The control cable of the ESC (trio wires with black, red and white color)
is connected with the throttle channel of the receiver (Usually CH2).
The #A, #B, #C wires of the ESC can be connected with the motor wires
freely (without any order). If the motor runs in the opposite direction,
please swap any two wire connections.
Note: You can use the transmitter to set the throttle channel to the
“Reverse” direction, and then the motor will run oppositely. Please
calibrate the throttle range again after changing the direction of
throttle channel.
