2 Features

2.1 Specially designed for 1/12 scale on-road competition. The eletronic switch, capacitor module and DC-DC booster are all built-in, save space on chassis.
2.2 Same Factory Pre-set Profiles as XERUN-120A-V3.1 (2-3S version). Up to ten profiles can be stored in the memory and imported or exported easily. Factory pre-set profiles include:
Blinky mode, Modify Mode, Stock mode, Practice mode, etc.
2.3 Aluminum Upper and Bottom Case, giving better heat dissipation, and allowing higher current.
2.4 External Programming Port (EPP), easy to connect and also a power port for external cooling fan. 
2.5 Advanced Dynamic Timing technology, providing more customization possibilities for highest level competitions.
2.6 Precise throttle and brake control, setting of drag brake and brake strength with more options, new punch and brake rate control functions, and throttle and brake curves through the PC client. 
2.7 Integrated Data logger, recording the maximum temperature of ESC and motor as well as the maximum RPM, using LCD Programming box to check easily in the pits.
2.8 Multi Protection Functions, making your running safe with ESC and Motor overheat protection, low voltage cutoff and throttle signal loss protection. 
Easily programmed with the Multifunction LCD Program Box and USB Link Software
 (Note: The V3.2_121204 or later version USB Link Softwarer is stongly recommended for XERUN-120A-1S V3.1 ESC)
2.10 New USB LINK Software graphic interface, providing extra parameters for advanced settings. 
ESC firmware can be updated through the USB adapter in the LCD Program Box.

Advantage of 
V3.1 vs. V2.1

1. Electronic switch, long life.

2. Aluminum upper and bottom case, giving better heat dissipation, and allowing higher current.

3. External Programming Port (EPP), easy to connect Program Box and also act as a power port for external cooling fan.

4. Switch mode BEC, powerful output.

5. Capacitor module and DC-DC booster are all built-in to save space on chassis.

FirmwareGeneration2nd Generation (2G) Firmware3rd Generation (3G) Firmware

Advantage of 
new firmware

1. The 3G firmware has 10 factory preset profiles such as MODIFI, STOCK, ZERO TIMING, etc, one firmware is suitable for different applications.

2. The 3G firmware has more programmable items for extreme precise adjustments.

3. The 3G firmware has running data log function for performance analysis.
