Yes it will work for a 3.5T motor, but whether it's a good idea or not depends on the car/truck it's going into. if it's an on road car or a very light buggy mostly used on road, 3.5T can work (though I'm not sure why you would "bash" an on road car). For a heavier buggy, stadium truck, or short course truck....3.5T is way too hot of a motor. I doubt you could gear it down enough to even work.
hello, looking at it for a onroad car not off road buggy.. bashing is probably the wrong term but definately not for racing ...just toying with the idea of doing a drag type car.. i have a 5.5 turn in a sct run from a 120amp esc that is now a basher.. trying to work out if a 4pole is more suitable geared up.. just thoughts at the moment..
thanks for your advice either way...cant have too many cars can i...???
Well, I tried my 3.5T with this ESC and seemed like the ESC could not switch that quickly, the top speed wasn't very high and finally on 2nd full throttle the ESC melt down. Don't know if I got the faulty ESC or it just can't switch that fast. I now have another company ESC and the 3.5T is flying.
Try resetting your throttle range. If that doesn't work, try changing the dead zone at your neutral throttle point (it's a programmable option in the ESC). To engage reverse, you must apply reverse and return to neutral twice, and on the third time, reverse works. I suspect if it's taking 10-15 tries, perhaps your ESC Isn't registering a neutral throttle input between reverse inputs. Re-calibrate, make sure to release the throttle fully between throttle inputs, and your problems may go away.
Is it ok to use reverse with this ESC while in sensored mode? I have heard that this causes issues in the BrushlessHobbies 120a esc's which if I am not mistaken is also a Hobbywing xerun 120a v2.1 clone.. Wondering if using the for/rev/brk mode while in sensored mode with a Tenshock sc411 4000kv will hurt it? I have had this ESC for a while now works great in my Hyper 10sc with the aforementioned motor. Also I treated it with CorrosionX for waterproofing purposes. I cannot believe the value of this ESC!!. A bargain at this price. Currently I have it set up as an xerun 120a v2.1 with running V3.0_110930STOCK firmware also I use the hobbywing usb link v3.42
I've had no issues with mine so far, running it with a Turnigy 4 pole 4250kv sensored motor. I don't know what you've heard or read, but I'm going to guess the issues you have heard of are in regards to running the motor in the opposite direction in sensored mode. With a typical unsensored motor, you can simply swap wires to make it run in the opposite direction, but that isn't an option with a sensored motor. Some ESCs include a reversing function built into the firmware, but this one (as far as I know) does not. So again, the issue (or at least, the issue I'm assuming you're referring to) isn't with reversing your vehicle briefly in normal operation, the issue is with forcing the motor to run the opposite direction during normal "forward" operation.
If you look into the brushless hobbies LT4 you will see it is the exact same ESC as the x-car120 or hobbywing v2.1. Although the Brushless hobbies esc has a higher burst amperage then the Hobbyking, internally the mosfets and boards are virtually IDENTICAL. Brushless hobbies says specifically on their site not to run sensored motors in reverse with their ESCs. Only fwd/brk is recommended when running in sensored mode. I have heard several reports of this killing the ESC's. The Brushless Hobbies esc costs twice as much as the x-car as well. The motor you are running is nowhere near the power of the Tenshock SC411 4600kv my x-car esc is powering.. Look around people.. I can't be the first person to wonder about this. The other ESC's that this one is copied off of has the problem, why woudn't this one?
All I can say is that after 20 battery packs or so, I've had no problems with mine. I'm not sure what else you want to hear. Since you seem to be an expert on the subject, maybe you should find your own answers instead of asking for help, and then being a smart alec when someone responds.
The user manual is under the "files" tab. It's necessary to decipher the programming sequence. The short version though, is that you hold down the "set" button, and switch on the ESC (continue holding the button). the ESC blinks and beeps for several seconds enters the programming mode. You wait for the number of beeps that correspond to your desired function, and then release the "set" button. you selected your desired value by pressing the set button until the corresponding number of beeps/flashes occurs, then shut off the ESC to save your value.
my truck is very glitchy after installing this. goes half the distance as it use to and wigs out. ran straignt into a curb. fantastic. anyone know why that is? also, reverse doesnt work. installed on the nitro circus sct basher. replaced the 35 amp esc the truck came with.
this is not a plun and play system, you need to do the initial setup. use the instruction in Files: www.link page 4 is the first step. Then you might also need the programing tool to do advanced setup (page 5-6)
If it still behave strange, put back the 35a ESC and test the range again. there can be several issiues why it dont run correctly.
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.

Ottima esc. credo che ne prenderò altre. qualita' prezzo inconcepibile.
La consiglio a chiunque.
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".
