HW81020350 - XERUN - V3.1 BL-ESC - Black 120A

XERUN - V3.1 BL-ESC - Black 120A

Strongest:  Most advanced software functions
Simplest:  Built-in electronic switch saves chassis space
Easiest:  10 Pre-set profiles for Plug and Play
Most Reliable:  Innovative heat dissipation structure

XERUN-120A-V3.1 has 3 color options:
Blue edition: PN=81020340
Black edition: PN=81020350
Red edition: PN=81020360

Advantages of XERUN-120A-V3.1 speedo
-Aluminum bottom case improves the heat dissipation (The previous V3 speedo uses plastic bottom case);
-Improved heat-sink with 1mm gap between the cooling fan allows more air flow to reduce the temperature of speedo;
-Improved dust-proof design. Rubber rings are applied at the sensor port and the program port;
-Aluminum screws of cooling fan look better and more professional;
-Improved electronic switch has stronger current endurance to be more reliable;
-New firmware allows driver to adjust the throttle neutral range, and solves the "turbo lost in high temperature" problem in the previous version firmware.

Note #1
For 4-6 cells NiMH/NiCd or 2S LiPo, the standard cooling fan needn't be changed.
For 7-9 cells NiMH/NiCd or 3S LiPo, the standard cooling fan needs to be changed to 12V high voltage fan.


2.1 All in One. 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, Offroad mode, Drift mode, Crawler mode.
2.2 Built-in Electronic Switch, long life and high reliability, also saves space on the chassis. 
2.3 Aluminum Upper and Bottom Cases with optional colors, giving better heat dissipation, and allowing higher current.
2.4 External Programming Port (EPP), easy to connect and also a power port for additional fan.
