XERUN V2.0 Brushless ESC discussion thread.
 

I've been running this esc in my Xray 009 with SP 11.5T (Stock motor for this part of the world) and I have to admit that it can keep up with whatever esc thats out there. All it needs is a little more speed.

And also, the optional LCD program box is great for fine tuning and software updates. This makes the XERUN a great option for racers on a budget.

However, there's no discussion or tests done on this esc for the available software versions. Lets share what we know....

The available softwares, with the top being the latest are:

V1.10_090323a_m
V1.10_090323a_T
V1.10_090312a_T
V1.10_090205g_T
V1.10_090205c_T
V1.10_090205b_T
V1.10_090205a_T
V1.10_090115a_T
V1.10_090105a_U
V1.10_081025a_U
V1.10_080926a_U

I think this esc is very similar to SP GT ver2/ Much More Fleta ver3...

Yep, they are very similar and in fact I helped tweak my mates SP esc with my programmer card. But I don't think the internal hardware are the same coz both feels a little different. Not necessarily faster though.

Just loaded my esc with the latest software. Haven't tested it yet. Will see how it feels this tuesday.

Which sofware? the 323a-m? Let me know the difference.

yup the 323a-m. but couldn't run yet today. track is closed for night practice this week. bummer....

I'd like to try one of the 2.0 60A versions. I'm guessing they perform very similar to the other 2 previously mentioned. I really like my SP 1.1 and think this would better and for the price point, a real easy decision.

I just picked up the 120A v2.0 Blue version for $101 shipped. I think I got a good deal. Haven't even installed it yet into my TC5. Does anyone know what differences there are in the software versions?

Where did you get yours from? Thats a very good deal. Can you provide a link?

I bid for it on ebay:

There's a blue version!?... Darn!

As for the software versions, I still haven't had the chance to try them out. But so far all I noticed was the reverse function option is not available on a couple of them.

i have a v2 120A XERUN combo with the 3.5t motor in my schumacher!the problem is that when i conect the esc with the program card somes times the screen lights and some other not!i cant understand why that hapens.the contact wires is ok .do anyone else have a broblem like this?

are these sensored?

that is not a problem just the cap charging/discharging .
you will have that with most any esc.

They are sensored but can also be use in sensorless mode, it will switch automatically.

Where we can find these softwares?

You'll need a pc, an lcd program box and the latest software downloaded from hobbywing.com

Btw, raced the Xerun last weekend and it performed flawlessly. It was smooth on the infield but lacked speed on the straights, losing out to the latest "turbo timing" esc's like spx, rb50, ko bmc and so on. Hopefully hobbywing will have this feature in their latest softwares soon.

It sould more clear if you were talking about the USB link setup v.1.5_090704 :):):) Anyway,i have already install the latest software.In my case the Xerun is not as smooth as the mamba max i was running before.Its more aggressive on start even with punch on level 1 and throttle neutral range on 12% and throttle expo on my transmitter on
-50%.Maybe because im running sensorless?

If you're going sensorless, their ezrun system is smoother. Xerun works best with sensored motors.

note different firmware changes the feel of the motor and brakes.

Maybe .But EZRun is from 25 to 60A only. :-(

From your sig, I'm guessing you're running 7t. the 60A ezrun will handle it easily.

It's a 7T delta wound (7700 Kv and 575 W) equivalent a 4T star.Nothing to do with a normal 7T brushless :nod:

Which one do you recommend for mod 4.0t motor?

i use 323a-T

Havent tried 323a-m yet.
The mid to top speed is a noticeable different to 205g and feels smoother for a open, long track.

Has anyone tried the new USB link setup v.1.5_090820 ?

No updates for the Xerun 120 on this .V1.10_090323a_m is the latest one :confused:

i run with this 120A xerun and 3.5 t motor my shcumacher mi3.5 .when the outside temperature is 30 or more the heat protection stop the motor every 3 to 5 min ,in afternoon when the temperature is droop no problem at all without any overheat at motor.my spur is 89 and pinion 23 do you thing with a lower pinion would be better?in the instruction manual says that tha gear rate should be from 9.6 to 11 what does mean?

What are you running? 6v or 7.2-7.4v?If you're running on lipo try with a smaller pinion like 18T-20T to lower gearing.With 23T gearing is very high for a 3.5T motor.

9.6-11 is the recommended ratio for that motor. Right now your ratio is 6.96 which is too low for a motor that fast. You should be starting around 10 which means you need a pinion with 16T (89/16x1.8). Just make sure the motor can be adjusted enough to reach the spur with a pinion that small.

By the way, what on earth is someone who doesn't understand gear ratios doing with a 3.5t motor??!! That's waaay to fast for you I think... LOL :eek:

i didnt know how the gear ratio is calculating mister,i undertand very well what gear ratio doing ...read carefuly my post and try to be less ironic mister perfect!

xerun v.2 for brushed
 

i have the xerun 60A ver.2 Esc, and like it very much, but cannot race using my B.L motor coz in here they still not allowed brushless. So can i want to use this Esc with brushed motor?? (stock.23T),how?
i think the old version can run brushed, maybe i need to change the firmware?

No brushed mode regardless of firmware for V2.0

koval, I'm no mister perfect. But you stated that you knew the recommended ratio and what you were running is obviously very far off. Please understand that running a motor that fast and hot can be dangerous if you don't know how to harness it correctly. Sorry if I offended you...

Hobbywing_USB_Link_setup_V1.5_090820.rar software is out. Download at hobbywing.com to update your usb link software. However there are no changes for Xerun software. I hope they're working on adding turbo!!

xerun v.2 EZrun v.2 for brushed
 

What firmware version is still have Brushed mode ?

is Firmware 1.5 had Brushed Mode ?
Have you tried that ?

.
.

No changes to esc firmware so still no brushed mode.

brushed mode
 

the software version 1.5 had firmware changer
so if the firmware v2.0
changed into ex:
V1.2 or v1.1
there is possible to use old firmware to do brushed mode.

is this correct ?
