I accidentally burned the capacitors that are out of the ESC. Now, the ESC lights on, respond when connecting to PC etc, and to the receiver, but when I press the throttle, red lights flashes with my commands, but no power gets to the motor. Motor tested, it works. I just wanna ask if I replace the capacitors, will the ESC work, or its dead? The capacitors burned when I stuck the buggy in a tree and pressed full throttle. My mistake, but just wondering if I can repair it, its a great ESC! Any ideas?

After about 15 minutes of running, the esc starts beeping once throttle input has been applied - steering works(L/R). This is the second time this has happened, it came right after a couple of days last time, freshly charged battery makes no difference. Any Idea's?

Check your temperatures, make sure it's not shutting down. I don't know where you live, but if it's sitting in the sun for a while before you run it...

I purchased this ESC along with a TrackStar 3.5T motor and my issue is that the motor barley turns when power is turned on. Do I need to purchase a programming card and program it or is there something wrong with my ESC?

have you set the throttle limits up when you first installed it? is the sensor cable in tight and have you wired the 3 power wires correctly?

Will this run a brushed motor

No. You could do firmware changes to make it do so, but..

to change direction of motor rotation, you must use usb adapter and go in software to change forward rotation direction. Sensored won't work the way sensorless will, but in sensored the brakes are more sure and throttle is smooth.

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".
