Xcelorin combo problems
 

Hello all.

I have the 4.5 combo and so far I have not had much luck. Had lots of interference and issues with a cogging affect. Anyway after moving everything around in the car and getting a Spektrum Receiver voltage protector I thought I was about there.

However 2 weeks ago it stopped working. Could not get the Speedo to work, when I powered the car on the servo for the wheels worked, but no joy from the ESC.

Tried another handset, different crystals, and a different 27mhz receiver. Still no joy. ( i had tried to sync it with the new receiver while holding down the red button when switching on until the yellow light appeared, but when I pulled the throttle, the light did not go green as it should. Also tried reversing the channel)

Tried a replacement sensor cable, no joy

I then tried the replacement receiver with my old brushed esc and motor, it worked fine!

So i flashed the Losi esc with the latest firmware, but still nothing. Could not sync it with my radio gear.

Sent it back to DMS (who were very polite and helpful) and they passed it on to losi. Losi advised no fault found to quote the job sheet " Tried everything to make it not work, but performed flawlessly!? Have re-loaded all the firmware and restored to factory settings and re-tested under extreme loading, no fault found. Returned".

Now it has not cost me for investigation by losi, but I have it back now with the same problem. It has already cost me £12 in p&P and i am not sure what else to try. I have a mate coming round tomorrow with his ZX5 RTR kit which has the same radio gear as me so was going to see if I could get it to see that. Failing that I will take it up the club Sunday and get some of the guys to try it with their radio gear, but i am not feeling confident.

Can anyone think of anything i may have missed? So far not overly impressed with the combo! If i do have to send it back again i will of spent so much on P&P that i may as well of go a Novak system :(

Thanks in advance

Dave, give Ryan a call at Horizon on monday morning since if they could not see the problem but for you it still exists then it must be somthing that is within the car/equipment. To be fiar as helpful asthe forum is you will only probably get lots of "possible ideas"etc but Ryam should be able to give you some clear and straight advice.. :)

As far as P and P making it as dear as a Novak, you have got a Loooonnnnggg way to go mate to catch that gap up, the Losi combo is £114.95, the Novaks are nearly £200 ;).......... (£85 in post, now thats a LOT of post :o)

Are you never off duty mate :) Cheers i will give him a bell.

Just going home now....spent an hour on the phone to Chazz at X-factory talking work stuff, have got bloody man flu and feel crap :cry:, so time to call it a night and head home for dinner and sleep ..........

have a good weekend

Just a thought are you running a fet servo if so check the choke is ok.

Hi, not sure what you mean?

Does your servo have a blue wire that you conect to the positive on the battery the choke (a little capacitor) goes between the servo and the battery. This is for 7.2 volt servos only.

hi, no i don't have this, just the red, white & black wires

I then tried the replacement receiver with my old brushed esc and motor, it worked fine!

could it be your other receiver have you tried your old brushed esc on the other receiver not the replacment.

Is the light on the speedo staying yellow even when you try to set it up?
Does it load up on the software on your computer?
Because mine stopped doing that and I sent it straight back to the inports and they said that I had blowen somthing inside the speedo. But I even had trouble with it sunday, but that was down to my handset because I had only brought the new ko handset. But if you are still having trouble look up tyreman on oople, he knows about losi products and he helped me last sunday with my speedo and it is working perfect

hi all

Thanks for the replies. Yes the light stays yellow and does go green when i try and sync it to the receiver. I can access the ESC via my laptop however. I tried the original receiver and had problems, but will try again to be sure.

Last ditch attempt!!
 

Hi,
Am after settings that have worked and are still working in a 6.5t combo. I am using 3200 lipo in a yokomo Bx. I need someone running simlar cars/ set up.

Altough on normal timing, medium acceleration, the car becomes hesitant after initial acceleration. The lipo cut off set at 6.2v.

Help me please...sloth

Hello All

Just to let you know i tried another reciever and it worked. 3rd time lucky :) Just got to buy one now as i used a mates to test!

PS - Sloth i am still learning myself so can't off much help yet, sorry

Thanks any way!

hey fella

ok if it was me i would set the acceleration to give maximum responce and increase the esc timing for it t be hesitant on acceleration the esc cant be seing the hall sensors in the motor at the correct point of timing ive yet to play myself with the losi esc but the princeple of the hall sensor and the three phase dc motor would sudjest there is some form of con flicting information.

2 mates had these both felt a lack of punch and other niggles, both now have nosram speedo and motor and no problems, looks like you pays your money and takes your choice.

There is no problem with "lack of punch" with the Losi system, it has as much or as little as you want (and set it to have)........

Settings please
 

I have given up. Re- caliberated transmitter. Downloaded firmware. Reduced this and that and still gets hesitant. The first minute or so all is well, on a fully charged battery. Then it drops off. The batteries still have plenty of ummf, in fact last another ten minutes from this time.

On advice i have knocked back lipo cut off as far as possible (6volts is lowest it will go). Now what....I am not that stupid but am feeling that way.
FYI is the same for med acceleration/timing and the quick 'higher settings'.

Help:(

darren
thay could not get it as good as the nosram systems, infact one had to turn his power ratings down. they tried all the recemended settings on the losi system

im not saying the losi system is no good,, we did not feel it was a full blown race spec, more of a club system, thats reflected in the price, and for that price its dam good value

I can only commetnon my own (I have three of them) one in my X6 which was "one" of the fastest/punchiest cars at our egionals this year (Mid South), another is in my T/C which has been on fire since I fitted it at our local club which gets a good turnout of drivers each week and everyone comment sthat it is one of the fastest cars on the track and the last oen is in my X5 which is equally as impressive. From my own experiences I have found them to be great and not just a "budget unit" but one that can mix it with the best.

totaly agree with darren the losi system is as good as the others on the market plus you can give it your own personel touch. we had a simular situation with the mrt tsx esc a couple of years ago people were saying they wer not as punch as the vfs1 ko units but it was proven on the bench they were pretty much identicaland the feel was down to the ko been brutal on throttle responce as the tsx had twice as many responce steps thru the trottle range hense making it feel smoother but stil had as good maybe better power.

Cutting off issues...
 

I have a 3.5T and a 4.5T combo.
I am running Lipo 5000mah with 20c max- Yuntung or something..
My problem is that the speedo is cutting off if I put the pedal to the metal..
I am very pleased with the system with regards to programming etc, and I have concluded that it must be the battery who cant deliver enough amps to the motor. Anybody else has the same experience?

If I put the throttle to 80% it happens some times, but at 60% throttle never.
Should I just switch off the Lipo cut off, or set it to Nimh?

does it happen more the further the car is away from you? This is the problem i had. this was improved with a spektrum voltage protector. The other thing is to check is your acceleration setting, make sure it is not set to high.

We leave the acceleration as medium, i don't personally like low, and high isn't needed, i was pulling wheelies in 4wd on this setting.

I'm suffering from the same problem, if got an pro x11 5.5 motor and when I gas it cuts out, you come off the throttle and it goes again? Seems like a voltage cut off coming in when your pulling some amps.

I was thinking of taking the lipo cut off off? I have the throttle at 80%

Any suggestions??

I've had this problem. I "fixed" it by reprograming with the "quick card".
It can happen whenever you try to reprogram the speedo, so sometimes
you have to reprogram it more than once. I sugest that when you program it give it a quick test before your next race.

Iv sorted my one out, I have it set up on nimh and it doesn't cut out when you gas it, just got to be a bit carefull I don't run my trakpowers down too much when I'm practicing

But shouldnt Losi fix this with some software updates or something??

I would have thought so, I'm glad it works!!!

I had this same problem of cutting out and it does seem to be the voltage cutoff. I was having the problem when I had it in the 1/5 scale bike with a 3.5t motor + lipo, it just cut all the time, but now Ive got it in my 501x with a 6.5t motor and lowish gearing +lipo and its fine on the same settings. I forgot to change the setting to Nimh when I swapped to 6cells which bloxed my race, but that was my fault :lol:

Hi guys, I've just installed an Xcelorin into my XXX-CR. (Hope it works fine after reading the comments posted on here...). Due to the height of the speedo (with fan), the bodyshell no longer fits onto the chassis very well (the holes in the rear of the shell no longer line up with the body pins on the chassis).

What do you suggest? Is there a replacement shell out there that will fit the XXX chassis better with this speedo installed?

Cheers,
Paul.

(Just answered this in your other thread if its any help)

Yep, got it, cheers. I race indoors off road on carpet so I'll try it with fan on first and then remove it if temps are OK.

Cheers.

I run without the fan in 2wd without any problems.

cut-out problem
 

your speedo has a cogging problem by the sound of it. try to speak to one of the lads with a GM speedo.

Hi All

Have another weird problem now. USB dongle has been replaced so that is sorted. My remaining problem is with Reverse! With the latest flash (D010128.LSC, it does not work. I have calibrated it many times, but when i have full reverse a red light appears on the ESC and occasionally it jerks forward. I have the Acoms 2.4 ghz wheel system, have tried the 2.4 setting and legacy. When i flashed the esc i reset to factory defaults and the read settings before making any changes. I even flashed it twice. Now here is the odd thing, i have reverted to the old flash (D110125.LSC) and after calibrating reverse works perfectly!:o

Any ideas?

I bought an Excelorin 6.5 for xmas, and it was working fine over the hols, then developed a fault with the esc all of A sudden. Would just judder when throttle opened, and all the lights went a bit crazy. I sent it off to Horizon on the Tuesday, and it was back with me on Thursday, with a new esc! Truly excellent service, and it's been running fine so far. I am well impressed with the service, so just thought I'd share for anyone deep in thought over which system to get (like I was a few weeks ago!).

:D

Is that you Lloyd?

known issue (now - me and snother oopler had a slog getting it recognised I can tell you). If you send it to horizon they can flash with 1.28 and it works, but the version on the website is borked somehow. Anyway they are looking into it.
