Xcelorin 1/8th Scale Brushless System

[Xcelorin_Brian]

Post your questions, comments, and setups here for the Xcelorin 1/8th scale system.

[SlashWho]

What is the max temp. you want on a 2100 xcelorion? and is it possible to add a fan on the heat sink? thanks

[Xcelorin_Brian]

SlashWho - 160F is an optimal upper limit for the motor. Efficient power delivery and safe of the components. The motor can go higher a time or two, but you don't gain much and I wouldn't recommend continuous operation above this. Our heatsink fits well in the 8IGHT, but doesn't readily support a fan. There are several other heatsinks on the market that fit that motor and can support a fan.

[SlashWho]

thanks for the reply here's the thing now it doesn't run at all the good thing is it never got hotter than 150 but now after recalibration the blue light won't stay on steady. when i apply power the motor flutters and that's it

Hello, I'm the proud new owner of a 8ight E. It has the 1/8 Excelorin and 2100 kv motor. I have been experiencing a couple of problems. FYI, I bought this car on consignment from my LHS. The electronics were brand new and had just been turned in by the previous owner due to some defects beforehand.

1) In forward w/ reverse mode I can not get reverse to function properly. I have been through the calibration steps dozens of times. Tried the software setting the reverse rotation mode. Tried the card. I've tried to calibrate with the throttle reversed on the radio as well as in Normal mode. The reverse setting it won't even go into programming mode, only Normal. The problem is I will wait for the 2sec delay, then hit Reverse and it will go in reverse BUT it will now STAY in reverse and will NOT go forward any more. I have called Losi's support line and we basically tried everything I did to no avail.

2) The radio I'm using is an Airtronics mx-3 FM and I get some pretty bad glitching. I have upgraded firmware like Losi support told me to try but the glitching is still there. Would 2.4 ghz fix that?

Thanks, your help would be greatly appreciated.

[Xcelorin_Brian]

Chris - Have you tried changing the radio type setting to Legacy in the Setup Software?

Chris - Have you tried changing the radio type setting to Legacy in the Setup Software?

I did try that. ;)

[Xcelorin_Brian]

Chris - Darn; couldn't be that easy. The glitching that you mention is usually associated with the different operating frequencies of crystal radios versus DSM radios. Have you tried another radio and/or receiver?

I plan to buy a Spektrum DX3R in the near future so that is not as much of a concern at this point. That is unless the glitching continues when I try a 2.4ghz DSM2.... :eek:

I'm more concerned about the lack of reverse functionality at this point. I don't plan to race it much but I would like to have reverse for those practice sessions at the track and the occasional trip to the local construction site.

Here's a freaky one for you guys. Got the 2.0 e with the 2100kv motor, I have the latest software installed. Here's the thing, I want to limit the throttle to make it a little smoother to drive. When I adjust the throttle curve it freaks the brakes out, any adjustment on curve makes the brakes work almost as if they are ABS. It has strong brakes when you hit them, then within a second the brakes are almost gone... really makes it hard to drive into a turn at the track. If the throttle curve is not used the brakes work great. I called Horizon Tech and the guy said they were all like that and I needed to learn to live with it. I think I'm going to send it back in and see if I can get a new ESC... this can't be normal. Anyone else have this problem?

[Xcelorin_Brian]

Chris - Our system is very compatible with DSM and you shouldn't experience any glitching. The braking issue, however, seems to be unrelated to the radio. What LEDs are on when you turn the ESC on?

Deej - We are aware of this problem and working on a fix. Sorry for the aggravation. You shouldn't have to just learn to live with it; it should work and be enjoyable. I apologize for the feedback you previously received. We will shortly be releasing updated 1/8th scale firmware and Setup Software to allow you to select low and medium initial acceleration. This should help smooth the starts so that you can go back to a linear throttle profile. Nonetheless, we need to work this out so it's no longer a problem. Stay tuned.

Good to hear about DSM. When I turn it on the blue/yellow LEDs are on indicating Forward/Reverse operation right? When I pull the throttle back it goes forward fine and the green LED comes on at full throttle. Now, I wait 2-4 seconds and then try reverse. It reverses fine. I noticed the green LED never comes on when I hit full reverse. Now here is the strange part. After letting go of reverse the green light comes on and stays on when I am in neutral. And now I no longer have forward control at this point, only reverse. It's like it changed back to profile #2 because the yellow, blue and green LEDs are all on at this point. I have to turn the esc off and then back on to regain forward control. I am on profile #4 when I start this whole process and calibrated several times through my trial and error. Also I have it set to 4s lipo cutoff for my 4s Losi lipos that I run.

Is Reverse even known to work in these ESC's?

I also had the issue - but when i set the curve i could not get more then 50% throttle. I then used the computer to put the curve back to standard however it would not reprogram the ECU. 50% throttle and strange breaking was the best i could get.
A few days ago i update the firmware on the controller (to the same version) and this resolved my issue of getting it back to factory settings

Yeah, I had also re-installed the software several times and was able to get back to defaults. I'm able to run it no problems there, just can't "smooth" it out.

Check the Software/Downloads section or http://www.losi.com/Support/XcelorinDownloads.aspx to download the latest 8th scale firmware and setup software. Enables selection of low and medium initial acceleration for smoother starts and fixes a bug where changes to the throttle profile would affect the braking performance.

FYI, I am NOT having problems with braking. The issue is with Reverse. I don't think the new firmware will help my situation.

Ok I downloaded and installed the new firmware and gave it a quick run up and down my hall - all looked to work fine. Went to the track today (1hrs drive) and did one lap of the track when the car would not go at all, looking at the lights on the back the red one was blinking. I tried to us a different pre programed setting but still nothing.

At home now putting on the firmware again (F01.01.22) anyone else had this same issue?

After putting on the firmware still nothing the motor just gitters and does nothing - HELP

[Xcelorin_Brian]

Sounds like your ESC may be bad. I'd recommend contacting Horizon product support for repair or replacement.

[Xcelorin_Brian]

We have identified a problem with both the new firmware (2.2) and the previous firmware (2.0) and also both v3.0 and v2.0 of the PC Setup Software. There appears to be a bug associated with the throttle profile that affects the braking performance. Whenever a custom throttle profile is used with braking percentage of 0-10%, the brakes will lock up on initial application. We will continue to work to find a solution to this problem, but here are two potential workarounds in the meantime:

1. Use the standard linear throttle profile and low or mid initial acceleration to smooth out the bottom end. This will give you 100% brakes and you won't experience the brake lock up problem.

2. Set braking percent to 20%-50%. This will allow you to use a custom throttle curve, but will limit total braking.

For those using reverse and getting locked brakes, downgrading the firmware to v2.0 will resolve this issue. However, you will lose the ability to select low and mid initial acceleration provided in v2.2 of the firmware. If you are interested in receiving v2.0 of the firmware send me a PM with your e-mail address and I will send it to you.

[darmawaa]

Today when I play my 8E with excelorin, the LVC cut off (red light blinking) even with new charged battery (5000mAh 4S). Yesterday it's still OK. LVC set at 12.8V. I try with other new battery (tested 16.75V), same problem. Anybody experienced that?
I already upgrade to new 2.2 Excelorin 1/8 software, but yesterday the problem only locked brake after reverse, now LVC cutoff even with new battery.

News after 40 days ??? :confused:

[Xcelorin_Brian]

Skiev - I apologize that it has taken us a while to get to the bottom of this issue. Since this issue was reported to us on October 3 we have been working hard to find out exactly what the cause is. We have also been working to make sure that whatever fixes we have proposed did not introduce other problems. We are in the final stages of testing updated firmware to address the braking issues and hope to have the testing completed in the next week or two. I have sent an e-mail to you and would appreciate a reply when you have a moment.

Any update on this? It's been over 3 weeks since that post. I'm hoping to do a firmware update soon.

[chiro972b]

Ok, now four weeks. Is anyone looking at this forum? Seems awfully quiet around here. I'd love to update my firmware on mine. :mad:

[wiggit]

i'm also checking daily for updates as i'm sure they will be out as soon as tested thoughly.I would rather wait for a release that thas been tested than a quick fix or another one with an issue in it.Fingers crossed some final testing took place this past weekend with the race(1/8 electric championships) that took place.Adam's truggy seemed to run really well! Not sure about buggy results but i think i read Kevin and Todd's seem to also be working pretty good!

[wiggit]

From the sounds of it extensive testing is going on.Hopefully there will be a new release out in about 2 weeks.As you can guess trying endless combinations to test for glitches would be a daunting task.So keep your fingers crossed for good results and a hats off to those doing the testing not a fun job.

[chiro972b]

I have no problem with them trying to get it right. I would love to have this thing work like it is supposed to. So take whatever time needed, but an update now and then would be good. I went ahead with this car even though many of the people I race with tell me I'm nuts to use the stock ESC. Theirs have all fried the ESC. The last holdout had his go south this past weekend at the track.

I'd like mine to work and not emit the "magic smoke of death" :eek:

[GatorsRun]

I just bought a brand new losi 8ight E with Excelorin ESC. I have been trying to figure out all day why reverse doesn't stay. I set it up with pc to have forward and reverse. If I hit reverse first it is there. But then if I go forward reverse will not working any more even if I wait for delay. If I turn on car and go forward first then no reverse at all. I am running
2- 2cell lipos. I made a Y wire setup just like the E revo so it sees the batteries as one 4s.
When I setup using lights and tiny button next to power switch for car I setup for 3 lights Yellow, blue and green. But once I go forward it loses rev and lights go Yellow and blue.

**problem was caused by having esc set to Legacy, should have been set to 2.4ghz. This problem has been resolved.

[Farmer_John]

I gotta say that I am not impressed with the first Losi product that I have ever bought.

I downloaded updates, did set up and then headed out to my local track and made it through my first qualifier.

that was the end of the functionality of the Losi esc. 5 minutes, plus a little pre-run time.

Not happy. Want it back?

[GatorsRun]

Don't judge Losi by there ESC. I have had the Nitro Truggy 1.0 and 2.0 and as far as vehicles go they are top notch. This new ESC venture they have plunged into is just not what there used to doing. Get a Castle and you will be very happy. The Castle even recongnizes what cell battery you have and automatically sets the low voltage cut off. It is a much simpler system. I have it in my E revo.

The ESC. does not like two 2 cells in series. I had the same issue and then went to a 4cel and all was fine.

[Hitman]

My ESC. is making the motor kog really bad. It is fine with no load on the wheels. When you put it on the ground it kogs and will not move. I have updated to the latest ferm ware.

any ideas.

Thanks

[Farmer_John]

Anyone know who to get hold of at Horizon to get this thig fixed?

Ordered a MMM this morning. I was cautioned about the esc when I bought it. Now I know it's true.

[GatorsRun]

The ESC manual has the address to send it back to Horizon. Send a copy of your receipt with the part.

[wiggit]

There is a lot of reading in this thread.I haven't been into electric for long but running losi products for a few years.I wil say that there customer support is very good.I haven't had any issues with my esc so far.I'm running the original software it came with.I know they are testing a new release rite now.I have a couple of buddies that you can't count on both hands that have sent back castle,mmm with issues.This isn't about that though.Contact product support on the horizon site and they will get you sorted out.All esc have had issues.There is so much mixing and matching in this part of the hobby it only adds to the chance of error be it an oops i shouldn't have done that to a issue of some sort.Not saying it is all user error but it happens.I do know the losi team ran very well with there stuff at 1/8 roar championships just recently with no issues i heard of.So be patient as i'm being also and the release will be here before we know it.So with that being said they are working hard on the release and product support is very good so leaves me with a great outlook for thier products.The first few pages of this thread have a lot of great advise to follow leading up to the new release of software.

[Hitman]

Contact Bill Goldsmith at Losi bgoldsmith@horizonhobby.com
He should be able to direct you in the right direction.

[GatorsRun]

I hooked the car up with just 1- 3s lipo and it still has the same problem. No reverse after using forward throttle.

[GatorsRun]

Day 3- Trying to get this piece to work properly. I think the problem has to do with the Calibrating between the DX3 and the ESC. I followed the directions and did full throttle cal light went solid green ok, then I went full reverse and light went solid red ok, but when I went neutral it flasahed blue and never went solid. Now that I tried to calibrate now it has rev all the time and forward only until I use reverse. What am I missing on this calibration?
It says brown from esc to receiver is - and red is positive and that is how I have it connected. There may not be anything wrong with ESC I just need someones help.

**problem fixed, had to change from Legacy to 2.4ghz on esc

[Hitman]

Make sure you have the throttle and steering trims at 0.
including sub trims. Then calibrate the radio to the ESC.

Check the on/off wire and or the reciever wire to the ESC. there might be a broken wire.

[GatorsRun]

Ok, I figured it out. ESC was set to Legacy not 2.4ghz. I now have forward and reverse. Doesn't this ESC recognize what cell size battery you have in car? It seems like the directions are telling you to manually go into the esc everytime you change from say a 3S to a 4s to a 5s. If I was to forget to tell the ESC what size battery I am using it could allow the voltage to go to low if say you had it set for 3s and was running 4s. I guess the fix for that is only running 4s and changing all 3 profiles to 4s. At $200 a battery I wish it could auto set like the Castle.

[Xcelorin_Brian]

Firmware version 2.3 has been released for the Xcelorin 1/8th Scale Brushless ESC (LOSB9516). This version fixes braking problems linked to custom throttle profiles and running in reverse. Right click on the link below to save the file to your computer. Then use v3.0 of the Xcelorin Setup Software to update your ESC.

http://www.losi.com/Content/Support/Xcelorin%20files/LOSB9516%20firmware/F010123.LSC

[Xcelorin_Brian]

GatorsRun - Sorry you had problems calibrating your ESC to your radio. The Xcelorin ESC does not automatically determine the cell count. There are a number of reasons for this including safety. For example, a partially discharged 5S can have less voltage than a fully charged 4S lipo. If the ESC thinks this is a 4S lipo, it will allow it to be over discharged, possibly damaging the battery or worse. We are looking at ways of adding this functionality without putting out customer's safety or investment at risk.

[wiggit]

Had a chance too do some testing today with the new software.Worked flawlessly!
Hats off too Brian and the staff for putting in the hard work for this new release,it was worth the wait.
Thanks Guys.

Hi, i'm italian. I have a big problem with my xcelorin kit. this is the video of the problem. if the motor is running the is no problem but if is stopped it has difficult to start. please try to help me. bye

[GatorsRun]

Thats how it's supposed to work. Just kidding. Did you calibrate the end points on the radio. You have to sink the radio with the esc by pressing the button in next to switch while turning on it should turn yellow. Then follow the instruction which describe holding full throttle, rev then neutral in manual.

[chiro972b]

Can someone help me figure this thing out? I bought a new 8-e 2.0 and DX2S. I set up the ESC without messing with the radio defaults. Seemed to work fine but I was slow down the straights. Someone mentioned end point adjustment so I looked. I'm at 100% so that's not it. But wait! It goes to 150%! So I set it on 120 and WOW! lots of power now.

Am I overdriving the ESC? Or should I set the EPA to 150 and re-bind the thing? Will I go back to being slow? Or maybe even have more power?

BTW, the instructions for the ESC and radio are terrible. So many missing things. Certainly could be why this ESC has a reputation for being bad. Once I got mine figured out, it was absolutely competitive on the racetrack and seemed smooth enough. I just still want to have it completely right. Don't want to see any magic smoke coming from my car.

[GatorsRun]

Did you do the calibrations ESC/radio by pressing the button next to the switch and following the instructions? Also You should really do the trigger calibration. Three part cal full throttle, rev and neutral calibration. It's in the directions. I have my DX radio set at 100% and get plenty of full throttle.

[banana boat]

i just wished losi would not "force" you to buy the 8ight-e with the xcelorin system, its totaly unreliable to say the least ................i wish they would take $300 off the price and just sell it as a roller


at least if they are going to force you to get the car with the xcelorin system make it last more than 10 minutes before you need to send it back for repairs. i do not know one person who have not had there xcelorin 2100kv 1/8 scale system in there brand new 8ight-e stop working the very first time they ran the car.........the very first battery they all went bad are you kidding?***.............and they bought the cars at all different times over the last year or so

[Juan Valdez]

I guess I'll post a different opinion about the Losi 1/8th Xcelorin system.

I have had my 2100kv Xcelorin system for over a year now with no failures. It came in my 8IGHT-E 1.0 (the "Limited Edition" kit that was first released), so it is probably one of the older systems out there. The only issue I have had with it was a weird, inconsistent behavior in the brakes (locked up at low speed, weak at high speeds) when I first got it. After trying everything a buddy and I could think of with no luck, I reinstalled the ESC's firmware. No update, just reinstalled it. That solved the problem, and since then the system has run absolutely reliably. I ran 15 minute mains all summer with no temperature issues. This was on 4S batteries.

I guess I would suggest for those of you having issues with your Xcelorin ESC, try reinstalling the firmware and see if that helps. My electrical engineer friends say that errors can occur when flashing firmware onto a device (though its avoidable if the software is programed to check for errors), so I think reinstalling the firmware is a good thing to try if your having no luck with anything else. And if your having temperature issues, double check your gear ratio and gear mesh. I know these are obvious things, but we can all miss the obvious sometimes. I can't guarantee this will solve all your problems, but they are ideas that are free to try.

Just the opinion of someone who has found his Xcelorin system to be anything but "totally unreliable." Hope it proves usefull.

I belive you can do this.Buy a roller (LOSA0804 by Losi) and the electric conversion kit (LOSA0912 by Losi) and install your choice of electronics.So what your asking for is and has been availible for some time.
I haven't had any issues with 8 2.0E either.

[GatorsRun]

Is the conversion kit as good quality as the standard buggy chassis?

[wiggit]

Is the conversion kit as good quality as the standard buggy chassis?
Not sure what you mean.I belive it is the same parts that come on the 2.0e if you where to buy it.This kit allows you too use a nitro roller and make it electric.

[GatorsRun]

I had to go back to a previously saved configuration on my computer so I had to reload setup software but it can't find drivers for Losi usb. What do I do?

[chiro972b]

Did you do the calibrations ESC/radio by pressing the button next to the switch and following the instructions? Also You should really do the trigger calibration. Three part cal full throttle, rev and neutral calibration. It's in the directions. I have my DX radio set at 100% and get plenty of full throttle.

Yep, that is exactly how I did it, but with the radio at 100% it was a dog. Then I found out the EPA goes above 100, so I turned it to 120% (did not recalibrate, just turned up the epa) and the car came alive. Plenty of speed and power. Nothing got hot, but it was only 45 F outside.

I'd really like someone who knows to weigh in on this. I can re-do the calibration again with the EPA set to max, but honestly I won't be able to tell if it's working until I get to the track next time. Running on the street is hard to gauge. Felt strong, but couldn't make jumps and was getting pulled on the straight until I changed the epa.

at least if they are going to force you to get the car with the xcelorin system make it last more than 10 minutes before you need to send it back for repairs. i do not know one person who have not had there xcelorin 2100kv 1/8 scale system in there brand new 8ight-e stop working the very first time they ran the car.........the very first battery they all went bad are you kidding?***.............and they bought the cars at all different times over the last year or so

Well I think you might be exaggerating just a bit. I raced mine for the first time a week ago and three rounds of practice and three qualifiers and a 12 minute main and I didn't have the first problem with mine. I just have a little confusion on how to set it up properly, but even still, I had no problems with it working. I am knocking on wood as I type this because I have heard lots of stories like this, but so far mine seems ok. I am hoping to do the new download, but I want to hear some feedback before I do. The last update was a bit of a SNAFU, so I'll watch and wait. That's why I was happy to see it finally come out.

It would be better if we could se which profile the car is in by just looking at the lights. It seems it goes back to Yellow and blue no matter what profile you set it to. It does stay in the profile you set. It would just give piece of mind for people that would like to run different size lipos like 3,4, and 5 S. I wasn't comfortable siwtching profiles so I just ordered 3- 4s lipos. Just a suggestion to make it more user friendly.

P.S. the car and the system are fast with 4S and I am happy with performance.

Hello, I'm the proud new owner of a 8ight E. It has the 1/8 Excelorin and 2100 kv motor. I have been experiencing a couple of problems. FYI, I bought this car on consignment from my LHS. The electronics were brand new and had just been turned in by the previous owner due to some defects beforehand.

1) In forward w/ reverse mode I can not get reverse to function properly. I have been through the calibration steps dozens of times. Tried the software setting the reverse rotation mode. Tried the card. I've tried to calibrate with the throttle reversed on the radio as well as in Normal mode. The reverse setting it won't even go into programming mode, only Normal. The problem is I will wait for the 2sec delay, then hit Reverse and it will go in reverse BUT it will now STAY in reverse and will NOT go forward any more. I have called Losi's support line and we basically tried everything I did to no avail.

2) The radio I'm using is an Airtronics mx-3 FM and I get some pretty bad glitching. I have upgraded firmware like Losi support told me to try but the glitching is still there. Would 2.4 ghz fix that?

Thanks, your help would be greatly appreciated.

I have the same problem as Chris. I've installed latest firmware (F010123.LSC), tried 27 mHz am(traxxas), 2.4 gHz (airtronics). The same result.

[nirvanaman3636]

I just bought a brand new losi 8ight E with Excelorin ESC. I have been trying to figure out all day why reverse doesn't stay. I set it up with pc to have forward and reverse. If I hit reverse first it is there. But then if I go forward reverse will not working any more even if I wait for delay. If I turn on car and go forward first then no reverse at all. I am running
2- 2cell lipos. I made a Y wire setup just like the E revo so it sees the batteries as one 4s.
When I setup using lights and tiny button next to power switch for car I setup for 3 lights Yellow, blue and green. But once I go forward it loses rev and lights go Yellow and blue.

**problem was caused by having esc set to Legacy, should have been set to 2.4ghz. This problem has been resolved.


I tried switching it between legacy, and 2.4 but no reverse at all, not even once when I turn it on. It also hesitates, and acts like it doesn't want to go when I give it a bunch of power unless I stop completely, and hit the throttle 100%. If I give it a little bit of throttle, it won't speed up once it is rolling, it will just skip, and acts like it's out of range even when it's right in front of me.

[GatorsRun]

Have you tried downloading the newest software that came out this month?

Have Anyone solved problem with "no neutral" on Xelorin ESC LOSB9516?

[enzo thecat]

Just got 8ight 2.0 E from my wife for Christmas. Losi 5s battery. I installed the battery and tried programming esc to 3rd profile for 5s. Held down selector button and esc would not go out of blue. Could not change a thing. Tried forward and the esc would spin the motor.

Next I tried to get the esc to program using that card. Plugged in the esc receiver adapter and tires spun for .5 seconds. Now esc does NOTHING except, the blue light it still stuck on. So I thinks its completely blown now.

AARRRRGGGHHHH!!!!!! What do I do now? Exchange the whole buggy? Switch out the electronics? Call Losi? I have a feeling this will take several weeks either way to get this resolved.

Wait! You turn it on holding the button and the light should turn yellow. Then pull the throttle to full and wait for the green light to go solid. Then back to neutral and go full brake and wait for the light to go solid red then back to neutral. I think the manual says the light will go solid blue then but mine never does. I just wait a few seconds then turn the car off then back on and everything is golden. I haven't used the programming card, but the software that comes on that funky disc works great. Make SURE you don't have ANY spyware or virus checking or firewall on. Not windows built in or aftermarket. Make SURE you have FULL admin rights (getting all this done on my vista laptop was a PIA) and then the software should install properly and then you should be able to get it going. I do admit the instructions are HORRIBLE. It doesn't even really say how to hook up the USB nor how to hook up that card. ****, I didn't even realize at first that the setup button was that little dot on the on/off switch. I was looking all over the darn speed control. The manual I have doesn't ever say where the button is. Someone who knows how to write manuals needs to have a once over on that thing and totally re-write it.

Oh, and you should probably get familiar with the rctech dot com forums. Much better response over there. You have to wait days here for anyone to answer your questions and honestly, Brian has NEVER addressed my questions here that are VERY old. Randy from Tekin will answer questions on rctech within a day or so, so that is why I now have a Tekin in mine, even though the xcelorin is in my kid's car and does work acceptibly, I just wish I could get an answer to my questions regarding EPA's (which also aren't discussed in the *** manual)

[enzo thecat]

Lights wont turn yellow or even blue anymore. They are stuck on blue and yellow. Went to LHS and bout a Tekin rx8 2250kv setup. I had to tear apart and modify a brand new buggy. Not thrilled about that, but after all of this I still think its worth it. It is amazing machine.

BTW, waited on hold yesterday with Horizon hobby for 3 hours!!! (1 hour per call). No one ever answered. Thank God for speakerphones. I plan on calling them for warranty work on it.

[chiro972b]

Dear God a 2250?? What batteries you running? My 2050 on 4S is absolutely insane! Probably too much for the track. Good luck getting things sorted.

Its a Losi 5s. Can't wait to run it outside. Now I'm just trying to figure out what gear I should use.

[enzo thecat]

Called horizon and they are making me send in the esc and motor. They will examine the system.

[enzo thecat]

Update!

New motor and esc arrived. all installed and working perfectly.

[chiro972b]

Well after telling people mine was working fine, I went to the track yesterday and on my first lap of practice my ESC took a dump. Just sits there and stutters and won't move. Tried a different battery, different motor, rebound it to my receiver and reprogrammed it with the laptop. Nothing worked. Lights all work as they should but the motor just sits there and the pinion vibrates back and forth.

This was on it's fourth or fifth racing day since I got it. That's not real great life. I guess I'll be sending it back. I hope they have this stuff figured out and when I get it back it will actually last.....:mad:

[cul8tr]

What is the length and width of the 1300kv motor? My maximum length is 74 mm and maximum width is 44 mm. Working on a Revo rock crawler/racer. I don't think I really want a high kv motor. Thanks Duh, never mind I found it. I shouldn't have hit my head so hard at work. Thanks

[sabongi]

The shaft of my 2100kv motor broke and product support from horizon hobby says there´s no replacement rotor, is this possible???? Would i have to throw my motor out?

[cul8tr]

Man that stinks!!! I sure hope Losi can hook you with a new rotor. I just ordered a 1300kv for my LCC.

[Moto44]

I have a new Losi 2.0 e buggy coming next week. Anyone interested in the Motor & the speed control?

[enzo thecat]

I have a new Losi 2.0 e buggy coming next week. Anyone interested in the Motor & the speed control?

How much? I like having spares.

What are you putting in it instead? I have the Tekin RX8 with the 2230kv with the stock 15T pinion. Its so fast, its hard to keep the car from flipping end over end.

[Moto44]

How's $200.00 shipped, for motor & speed control combo. I have a extra Tekin RX-8 and 1700kv motor from my Associated Buggy I just sold. I figure it would be alot easier to sell the Losi speed control & motor due to the fact it is brand new. Let me know if your interested.

[Mr. Awsome]

hey everyone, i think i blew out a bearing on my 2100 kv xcelorin system and i dont know what to do... i can't open it up... am i not supposed to? should i jsut send it back? please help i am totally lost. t

thanks everyone

[baui]

Hello, i have a Losi 8ight 2.0 T.

Problem is 2 ESC i have killed....

Temperature on Motor is about 140 - 150 F when the weather is cold (about 60 F).
Problem is when the weather is warm, the i must stop temp is to high.

In Germany the batteries are limited to 4S hardcase lipos if you want make a race.

I want to know with parts i have to use i will down with the temperature.

Center Spur Gear is 46 and pinion gears 16

i have also center Spur Gear 48 and pinion gears 15, 14 13 and 12

Racetime is about 15 minute with the 5000 mAh 4S hardcase lipo
My last racetime was 6 minutes and the esc have no funktion.....

Sorry for my bad english... i am a german people.


thanks greets from bavaria....

I'm having a major issue with my 1/8 ESC.

I was doing a few runs up and down the grass when it suddenly didn't wanna move. Now it just sits there and stutters every time I apply throttle. I have tried re-installing the firmware(F010123), reset it back to factory settings, played around with timing, initial acceleration, dead band, radio type but nothing seems to help. It just stutters, like it doesn't know which way to turn, and yes I have tried reversing the rotation, same thing.

Without any load on the motor it will once in a while spin up, but less than one time out of ten it will just stutter. The motor and motor wires get quite warm after a few attempts to run the car, so does the battery wires up to the EC5 plug connecting it to the battery, the wires from the plug to the battery don't get hot and neither does the battery. There are no warning LED's showing something is wrong.

This is a 2100kv combo installed in a LST XXL with stock XXL gearing, so I know it's perfectly reasonably geared. The battery is a Turnigy 4s 35C 5000.

Any ideas?

[Neobart]

OK since I'm not getting any replies here I took it too my LHS where I bought it, I was reluctant to do so since they don't have a good reputation when it comes to warranty repairs/replacements. And sure enough, they didn't disappoint. :confused:

Basically the guy there tried to make it sound like it was my fault, and that if the middle wire from the ESC isn't on the middle tab on the motor the ESC will be damaged. Jeez, the manual clearly states that any two wires can be switched around to reverse the engine rotation. That was wednesday, I'm expecting them to get back to me early next week to learn what they've found. If they try and pin this on me, I will be very cross to say the least. This was the very reason I didn't wanna bring them into the mix, but I feel like I didn't have a lot of choice.

[Claypit]

How can I open Xcelorin 1/8 motors to replace ball bearings? Tried to do it, managed to get off the back plate and 8 screws on the can but thats it, nothing will become detached from that point on. I assume I should be able to get front side pulled ot from can, but couldn't manage to do it with conciderable force. Do not want to brake anything. Sending it back to losi for maintanance is not an option. BL motors should be constructed so they can be maintained by user...or am I wrong?
Any instructions welcome!

[Mr. Awsome]

i had the same problem too, i couldn't get the front off, and when i called losi they said that they couldn't do anything for me but that i could buy aftermarket parts, i told him i couldn't open it and he didn't have an answer...

[Mr. Awsome]

P.S. is anyone else having a problem when plugging in the battery to a new esc? my EC5 connectors melted together when i plugged them on

[BAM Motorsports]

i'd like to say what a bullet proof motor the 1700kv motor is

My Wife and i both run the Caster racing Fusion EX-1 with the stock esc that comes with the rtr ( hobbywing 80A esc) with the 1700 kv motor
During winter we run a 19T pinion (top temp of 10Deg C) off the motor giving heaps of acceleration and top end speed and during summer ( top temp of 40 deg C) we slide back to a 14 or 15 tooth pinion depending on the track

the motor's are *** bullet proof haven't hurt ( cant hurt) the motors in any way and are comming up to 12 months of racing under there belt

the lipo's are 2s2p 5000mah 35c x2 that we use and our run time is about 28-33 mins

i will be use the Xcelorin motors in all our 1/10th offroad and onroad cars in 2011 with Speedpassion GT2.1 esc's

if the 1/10th motors are half as good as the 1/8th motors i'll have to build a bigger trophy shelf

Has anyone used a Xcelorin in an lst xxl conversion? If so how does it compare to a mmm 2200 from castle creations?

[Ginjaroot]

Hey Guys,

Just wanted a little help from across the pond,

I have an old Losi 8E 1.0 with a new 2100kv combo, I decided recently to try out some different lipos, but have come up against some weird problems -

I was given 3x Thunder Power G6 65C 5300mah 4s packs to test out.

The problems are that I can't get traction as the buggy spins on the spot and the tyres start ballooning at mid to high throttle. If I use high throttle for more than 3 seconds then the tyres get shredded off the rims.

Here's the weird part, If I hold the throttle on full for 2 seconds, the buggy seems to find a power band or higher gear, which in turn causes the motor to whine loudly and surge forwards, When I brake, the brakes lock causing the buggy to slide across any surface.

I've got used to this now but it still poses a problem as I have to be careful when throttling down a straight, I have to brake 10-12 feet before the corner to stop me grip rolling when entering a corner.

I'm running a 17t pinion and 45t spur with a 4-5-3 diff set up.

Thanks for the help, if you can help me.

[Neobart]

Sounds like you're running old software in the ESC.

I remember there was problems with brakes locking up on an earlier release.

[Iikoo]

I had the following incident with my 1/8 xcelorin: after firmware update my car started to goc quite a bit. One one occasion when cogging occured, i tried to get the car moving with throttle. What followed was a puff of smoke from under the body. After inspection it looked like it came from the esc. Battery and motor are fine. After the incident the car/esc has following symptoms: car powers on normally, but when i start to drive the lvc kicks in allmost instantly. After a while i can drive for few moments, and then the lvc kicks in again. Battery is fine and full, have allso tried other batteries.

What could be the problem and can it be fixed? And the most important question, does Losi still fix these? I mean, esc worked just fine before the firmware update. Esc was allso barely warm when this happened. Battery was 5000mah 3s 35c.

[LARD]

Post your questions, comments, and setups here for the Xcelorin 1/8th scale system.

Hi Brian i have had my xcelorin for about two years with no issues untill i was racing in the South island champs here in new zealand the lipo cut out warning light flashes after 35 seconds of use the batterys are fully charged and are reedy 60c rated 5500mah 14.8 volt baterys (obviously only using one at a time) i have uptadted the firm were to latest changed the voltage cut to 12 volts but still no good. There is no Losi importer/ official retailor over here in new zealnd i emmigrated from the uk last year and am wondering if it is repairable or weather i have to buy a new one?? would appriciate your help wiyh this issue many thanks Steve Oyston

It sounds like something on the PCB board may have failed. We do not "repair" the ESC's but if your ESC is still in warranty, please contact our service department. I haven't seen any issues arise from the newest firmware upgrade, it was likely a coincidence.

Hi Steve - I would try to run the ESC with the LVC shutoff to see if the issue goes away. Be sure not to over discharge the batteries though, you should be able to feel them slowing a minute or two before they "dump."

Thanks for your reply! How can i tell if my ESC is still under warrenty? I dont have the receipt. Anyway to tell how old is my ESC? And how long is the warrenty in these controllers?

BTW. I purchased second hand 1/8 Xcelorin from Ebay, and i can't get the ESC working. Symptom is that it does not send any power to the motor! (2650kv Castle Creations). I have tried switching the motor wires order, but that did not help. Everything else works just fine: USB connection, link software and firmware upgrade (updated to F.01.01.23), calibration etc. After calibration ESC's light work as supposed to; green for full throttle and red for full brake. But still, motor is not "saying" anything!

Please any help would be very welcome!!

Thanks,

ESC warrranty is 120 days, but with a valid receipt. Without a receipt, it cannot be cover by warranty, sorry about that.

The new ESC is hard to diagnose without seeing it, but it sounds like you may have been sold a faulty ESC. If there are lights, and calibration is correct, the motor should spin. I would also try another motor to confirm.

[LARD]

Hi Frank will try that and update you thanks
