Hi guys. New to this forum, but this looked like a good place to get a question answered.
I have just joined the Hobbywing ranks thanks partly to the info I found on this forum. I have a Xerun 120 & a Ezrun 25 amp, both V2.0. My first question is about the 120 esc. I ran it yesterday for the first time & it was sweet. Something that I noticed, though, was when I go to plug the battery to the esc connectors together, a spark would jump between the plugs. I'm using the Deans plugs. The 25 esc didn't do this. Any thoughts??? Question two is about the fans. The fan on the 120 esc seemed to do fine. But the one on the 25 esc sounded strange. Sounded like it was speeding up & slowing down. I ran it about 5 or 6 five minute runs with a cool down period between each run. When I got home & removed the body, it had a burning electrical smell to it. If you connect the fans to the receiver & run off the BEC, will the esc stay cool enough? If left alone, how long do the fans last before burning out? Thanks for any help. i've got a hobbywing 60A with 5.5T combo on my b4 and i've also noticed the spark when putting the plugs together and the weird sound that the fan makes. Any inputs regarding this would be a big help. thanks! |

What is the best esc and brushless combo to buy from hobbywing.com I want to put it in a team associated sc10 rtr truck. I run the truck with a dutratrax 7.2 volts 3000 nimh battery pack. I dont' want to use lipo. I have plan to race with the truck at my local track this summer... Please, give me good advise :) |
I ordered a ezrun/8.5t(4000kv) combo and another seperate esc and all I can say so far is WOW!! I installed the combo in my sons slash and it is SOOO smooth and powerful. I have heard the talk on here about how smooth they were and all, well so far it's the case. I cant wait to get mine in my 8ight and try it. And the foot print in tiny, you can put it anywhere.

caloiski- all my hobbywings (and old lrp's) - made a little spark when I connected the battery - I guess it shows there is a connected circuit.
Don't know about the fan noise. I run a 9.5 and up in my TQ car with the xerun 60 and I don't even use the fan. I did have an old LRP Comp that had a hyper active fan, you could hear that thing spinning from across the track. Maybe use an aircan or air compressor to blow the fan out to make sure no debris is inside. they are easy to unscrew and unplug from the hobbywings. |

How do you know what cell count the esc thinks is connected? I don't hear any beeps when the esc is turned on or anything. And how many cells will it recognize? I will be running 4S on my 8ight, don't want to ruin a batt. Anyone know??

The EZrun 10scale ESCs autodetects the cell count. So far its never been wrong. I tested on my 60A to make sure it cut off on a 4s correctly and it does. A couple of things about running the 60A on a 1/8 buggy:
1. Keep an eye on temps. That's a lot of load for a small ESC. You should be ok if you're not too heavy and gear conservatively. 2. When you can, upgrade or add 25V low ESR caps as 4s is very near the rated voltage of the stock caps. Let us know how it does in your 8ight. |

You know what, the new 60A have 25V 470 mfd caps already x2!! Is that enough capacity 940mfd? Hope to run it tomorrow on a smaller track, will let you know how it does. |
i want to know who is using the fan on there esc and who isnt. ive ran my both ways with a 7 cell and no heat issuses. Im loving my 120a I think im gonna stick with Hobbywing for a while. I havent found another product as good for the price.

I'm assuming you mean 470uF caps because mF caps are GINORMOUS! Wow, I'm surprised they have 25V 470uF. Those are the same caps that HW used in the EZRun 80A (except that had 3 of them). It would be nice to have 1 or 2 more of those caps in there, but it's good to see that you're not anywhere near the voltage limit on those when running at 4s. Even 5s would be ok for those caps as long as the FET rated voltage isn't exceeded (that's the questionable part). 940uF isn't too bad. The more, the better, but 940uF is ok. |

I was hoping you would chime in:nod::nod: I beat around the yard a little tonight and the temps were only about 78F. It is cool out this evening and its not a race environment but I was pleased so far. It is very smooth in my 8ight as well. I always gear conservatively as I run with nitros and doesn't have to be way fast:lol::lol:

Yeah, if it's a small to medium track, you can probably gear for 30-35mph. Try not to pull on the throttle too fast as the fast the voltage is applied (faster you apply throttle), the higher the voltage spikes. Smooth driving will help the ESC (and this is true for any ESC).

Must've had a pretty big current spike. What was your punch set at?...default? Was there any cogging or light jerking? Could be that Neu motors cog pretty hard (strong magnets I believe)...they're notchier than Tekins and Medusas. I've run the 60A with Medusa motors fine. Sorry to hear that. I had a Neu-Castle kill my 150A ESC before, but that was because my wife was driving is very slowly around the track and the cogging killed the ESC eventually.

hey jsr i had a quick question for ya about cogging..if your running a clutch set up such as tekin, does cogging take a toll on your esc..wouldnt the clutch just slip and all be good??

trickedout - the clutch smooths out power delivery to the drivetrain, but the motor will still cog creating voltage and current spikes that the ESC will see.
brofoe - yeah, I love how smooth the 60A is. Too bad it didn't work for you. If I had the funds, I'd pick up a 60A and try running it on 5s. If the FETs can handle the voltage and the firmware allows it to arm, that may be a better setup as it will draw less current. Come to think of it, since yours is dead, would you mind opening it up and checking out what FETs it has (should have a P/N on the FET package) and quantity of those FETs? Then we can look up the datasheet and take a look at the specs. |
