- Page 2 120A/150A ESC X-Car 120A/150A Series Sensored/Sensorless Brushless ESC for 1:8 scale Car or Truck Thank you for purchasing the X-Car Brushless Electronic Speed Controller (ESC). The X-Car 1:8 Scale 120A/150A Series ESC is specifically designed for operating 4 Pole Sensored/Sensorless brushless motors.
- Page 3 X-Car Series 1:8 ESC Specifications: Begin to Use The New ESC: Please attend to each connections and Model 1:8 Sensored 120A 1:8 Sensored 150A make sure each assignment is correct. PN#Model 4212030 4215030 Blue motor wire A Signal wire Cont.Current 120A 150A Yellow motor wire B...
- Page 4 120A/150A ESC Note: Please refer to the illustration and connect the wire accordingly, wrong connection may get your ESC fried. ● Sensored Mode When using a Sensored Brushless motor, the Blue motor wire A, Yellow motor wire B and Orange motor wire C of the ESC must be connected with the Sensored motor wire A,B,C respectively.
- Page 5 identify the motor type (Sensored/Sensorless) via LED lights * If the ESC works in Sensored Mode, remove the Sensor wire and the ESC will automatically change to Sensorless Mode.

Cutoff Voltage ● Automatically detect the number of the cells According to the type of your batteries , set up the type of the batteries and Low Voltage Cutoff Threshold via PC software or program card.
- Page 8 120A/150A ESC batteries. If you are using more than 6-cell NiMH or NiCd batteries, you must adjust the cutoff voltage, for example if you are using an 8-cell pack of NiMH batteries you would use a cutoff of 5.6V volts (8 x 0.7V = 5.6V). When the voltage of the batteries packs is within 8.4~12.6V, the ESC will automatically identify 3S LiPos.
- Page 9 to operate. Note: There is automatic protection within the X-Car ESC. Only after you have stopped and returned the trigger to neutral will reverse become available. If while traveling in reverse, pull the trigger to go forward. This is to help prevent serious damage to the drive train. ●...
- Page 10 120A/150A ESC ● Normal (Default) Good mix of power and efficiency using any motor ● High More power than efficiency so run time will reduce, and you should be monitoring motor heat. The higher KV or lower turn motors will generate heat quickly using this setting. A safe high temperature range is 165F to 180F (74°...
- Page 11 ● Medium Medium requires more from your batteries, and is good for low traction surfaces. ● High This option will provide full acceleration and requires stout batteries to supply the load required in this setting. ● Very high This option will provide full acceleration and requires stout batteries to supply the load required in this setting.

Percentage Drag Brake 0%( Default) 4%,8%,12%,15%,20%,25%,30% The drag brake function provides the driver a set percentage of brake when you have the transmitter resting in neutral. This will create the “feel” of a brushed motor. Drag brake are used in racing to slow a vehicle as you let off approaching a corner versus the driver having to push the brake at every corner.

BEC Output 6.0V (Default) , 8.4V X-Car LCD Program Card X-Car LCD Program card can be used to set up all brushless ESC for RC aircraft and car produced by X-Car except Turbo SS120A.
- Page 14 120A/150A ESC How to connect the LCD program card: 1. Disconnect the battery from the ESC; 2. Disconnect the signal cable of the ESC from the receiver; then plug it into the socket marked with ( 3. Connect the battery to the ESC and turn on the ESC. 4.
- Page 15 Plug the signal wire into the socket marked with( )first. Then connect an additional power (5-12V) to the socket marked with ( ). Then switch on the ESC. If the sequence is wrong, LCD will not work properly. Note3: The power supply should be lower than 12V, or the program card will be damaged. Operation: *Working as an individual device to program the ESC, the function of the buttons are as follows: “Menu”: Change the programmable items circularly;...
- Page 16 120A/150A ESC “OK”: Save the current parameters into the ESC. If you don't press “OK” button, the customized settings will not be saved and updated into the ESC. If you just press “Menu” button, the customized settings are just saved into the program card, not into the ESC. E.g.: Firstly, enter the interface of a customized programmable item (e.g.: cut-off voltage 3.2/cell);...
