You can use the "USB Programming Adapter for Hobbyking X-Car 120A & 60A ESC", which works great.

Hola hoy me dejo de funcionar el combo... pero no se si es problema del variador o del motor. Cuando se le da gas o freno se le enciende una luz roja en el variador. GRACIAS y un saludo

Help! I am running this esc with a trackstar 10.5T motor and it is faster in reverse. I have tried everything I can think of without a programmer. I have calibrated it in reverse according to both the hobbyking and hobbywing directions to no avail. The wires are soldered proper a-a, b-b, c-c. Really at a loss here, even tried calibrating not in reverse on the transmitter. Every way I try this it is always way faster in reverse and is driving around like a slash in training mode going forward. I even attempted to adjust the timing to see if that did anything and it is still faster in reverse.

only solution is programmer reverse mode maybe your can reverse your gearbox miss the sensor cable and try to reverse 2 wires

If you don't have the programmer card, change the transmitter throttle to reverse (if it is normal) or to normal (if it is reverse). The swap any 2 wires (out of 3) to the motor.

Sorry pecky but swap wires ok but must remove sensor wire....however the motor will turn in the other direction *)

Mine worked Really good at first. But since yesterday, it stopped responding to throttle. And now it doesnt even connect to the programming card and the transmiter doesnt work neither, (yesterday I could steer when it didnt throttle.) sorry for my bad english. If there is a way I can repair it please let me know, its a great ESC!!

I received today.
This is copy of XERUN120A ver2.1.
Beware:The HobbyKing HKSS programming card for HK 150A ESC is not suitable for this ESC.

I love this ESC. it's small and light and handles 3s easily. To program you will need an older Turnigy programming card, it works perfect and gives you 10 different settings to adjust (check out my video on programming). Overall i would buy another X-car 120 amp ESC.

This is a very nice overall ESC for the 1/10 class, identical with the Hobbywing XERUN V2.1 version. Tested with almost all the suitable Hobbywing's firware and is working fine, the only thing i have to mention is that you have not an option to change rotation on a sensored motor with any of the firmware and the HKSS programming card is NOT working regardless of Hobbyking's statement on suitable accessories. So, although it is a very good ESC for the price , i will give only 4 stars as it came without user manual as well. I have already uploaded Hobbywing's manual,for anyone interested,you can find it on the "files" tab as: "HOBBYWING 60/120A v2.1 manual".
