I have a castle 2650KV motor will this esc work with this motor or do i need something bigger ?
 Gustavo 32 points
i'd not reccomend this ESC for this motor. You should look for and ESC that also support 6S. than you can enjoy the beast motor at the top... HOpe i've helped

depends on the rc you have the motor size and weight ,6s lipo may tear the car apart or be uncontrolable a 3s is good for most rcers watch your gearing and temps

Hello Hobbyking users Does somebody know whats wrong with my esc?! Always when I drive it with a 3 cell lipo and then whant to put a 2 cell lipo in it starts doing a pip noise. It also does that noise when I first put a 2cell lipo in and then a 3 cell lipo. Then I have to wait ca 1 hour and then it works again. Sometimes it starts to do that noise when I first drive it with a 2 or 3 cell lipo and then turn the esc off and then turn it on again. The esc or the motor never get hot when it does that noise. Can someone please help me? Thanks.

Are the bullet connecters already soldered?
 Dave 8 points
When I got mine a while back, it did not come with bullet connectors pre-attached. The wires were pre-tinned and ready to be soldered to whatever connectors or motor tabs I wanted to use.

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".
