WARNING! Losi conversion KIT
 
Warning do not buy the junk ARSE losi electric conversion kit. the plastic spur gear rubs against the rear center diff mount big time. JUNK JUNK JUNK not to mention that u can only use the plastic spur gear unless u want to cut up you losi race roller chassis and sand down the plastic part of the 45t spur gear, so glad my Tekno is coming. Others have reported this at other forums. Save your self $10 bucks and get the Tekno!

Pics? You say "others" have had the same problem. Why not everyone, if they are such junk? I think you installed it wrong just like the "others".

Look here are some pics, i may be new to brushless, but i am not new to RC. I know how to build and mount my stuff. I have taken apart and rebuilt my race roller countless time. this is an issue with the losi electric conversion kit. Its been a problem. The plastic 45t spur gear is wider then other spurs, and once u put it all together it rubs the side if the cnc'c mount PEROID. do you own the kit? if so are u using the 45t gear? The gear has to be sanded down a "little". there are others on here that have had the same issue. Look on rctech its all over that site. anyway im just telling others because this kit is a waste of money. you can get the tekno kit which comes with a chassis for $69.99. Dude dont be so rude next time. you are quick to insult someone. geesh!

Are you using the flanged 8x14 bearings with the plastic spur? If so I cannot see how the plastic spur can get close enough to the motor mount to rub.

And What's Nitro? is just a whiny baby, pay no attention to him, maybe he will go away!!!

we tried that with you and it didnt work :lol:



Just put the stock spur on.. its a bit excessive that your complaining about one peice on a car that was not originally intended to be electric. save your self the hassle and put the stock spur on..

Mentat 06.21.2009 08:18 PM

STOCK 48T spur does not fit, have u been paying attention? i am using the stock flanged and have the upgraded flang bearing insert that is aluminum. I sanded the outter part of the spur gear and its fine now, its just because the spur is wider

brushlessboy16 06.21.2009 08:32 PM

Apparently not, i misread the post.

This made me laugh, just thought you guys would like to know that.

Just wondering if you can flip the plastic spur over and have it sit closer to the diff cup? I know it has a metal reinforcement plate, does that go between the diff cup and the spur, or outside the spur?

Mentat 06.21.2009 08:47 PM

the metal is on the inside of the spur the side that sits right up against the cup., its mounted and i do not feel like taking it all back apart until my tekno arrives

Ryu James 06.21.2009 09:07 PM

hmm,
my buddy used to run a losi conversion on his 8t but he used the 45t metal spur that the kits used to come with. not sure if they still do but his worked. one thing i was gonna tell you though. dont use that little plastic half-moon thing that is designed to rest under the rear of your motor. when your chassis flexes that pushes up against your motor and will either cause your shaft to break, bearing to go bad, etc.

just ignore all that losi stuff and put your tekno together when you get it. and if you have any bild questions when it arrives you can pm me directly or post obviously. but that losi conversion is a waste of time like you say

DwightSchrute 06.21.2009 09:21 PM

i think the losi mount is junk but for a different reason. i like to go fast and i couldn't gear it as high i wanted to so i used the rcm mount. that thing ROCKS! I do like the losi battery box and the servo/reciever box and center diff cover so i buy them seperately at impaktrc.

i do have a couple of questions for you if you don't mind though...

1. did you put the center diff cover on and screw it down before you sanded the gear?

http://www.impaktrc.com/product_info...oducts_id=3196

(the oval looking thing that goes over the center diff.)

the reason i ask is if it's not screwed down evenly or at all yet, the mount and the mount on the other side can sometimes be mis-aligned and cause the binding. it's happend to me before i put it on.

2. you said you've re-built your roller many times, so this one might sound dumb, but sometimes i forget about it too....did you tighten the diff screws that hold on the gear in a star pattern like it says in the manual? i've done it in the wrong order before and it had rubbed against the mount too. after i re-did it the correct way, it was fine.

Bondonutz 06.21.2009 09:23 PM

Good to know, I was thinking about a 8ightE but now I may go the RC8 and Tekno chassis and save some $$$. Still confused ?????

Mentat 06.21.2009 09:34 PM

Yeah i have done everything, had the mount top on etc... the spur gear is alot wider then a steel spur

out of the 4 8ights i have, i've had to sand a couple of the plastic gears which is no biggie for me, but they do make a 45t steel one that does come with some of the kits.

it's weird, mine came with a plastic one, but my friend's came with the steel one. i ended up buying a steel one just for back-up, but i wonder if they may be slowly changing the kits.

i'd love to get a tekno kit, but they don't make a long shafted 23-25t pinion, so i'm sticking with the RCM mount. it's fabrication is amazing, and worth every penny imo.

the plate goes on the diff cup first then the gear goes over it, the op may have put it together wrong

its a nice set up because you dont have to open the diff to change the gear, and on a side note they seem to last as long as kyosho nylon gears, as long as you mesh them right they will last years

Mentat 06.21.2009 09:45 PM

OH and this kit doesnt come with mounting screws for your motor either

Ok, NOW I see it. Yes, I am quick to insult anybody if they make rash judgements without evidence to back them up. If you come out of the gate with the attitude you had in your original post then I don't see why my reply was insulting to you. That attitude does not fly very far here, particularly not with me. I'm actually surprised noone else said anything. You completely bashed a product made by a very reputable company without any proof except for some vague indication that some others had the same problem. Only after I questioned you (2 hours later) did you actually put up some pictures to reinforce your claim.

My point is that if you had posted the pictures initially, (not 2 hours later) that would have avoided this argument entirely. I would have seen the problem and your tone would have been justified.

himalaya 06.22.2009 06:02 AM

I have the same problem. I replaced the steel 45T spur with a plastic to have a quiter enjoyment. I spent 2 hours trying to get the center diff spin freely, after countless assemble and disassemble the spur was still touching something. I finally figure it was the chassis! dremeled a tiny bit(0.1mm depth I guess) of chassis off right under the spur, the problem goes away. and like Mentat's picture shows, the spur was so close to the mount that I can't insert a piece of paper into the gap.

Now my center diff spins freely, but new problem comes up. This time it's the pinion's turn to touch the mount. I have to pull the pinion 1mm farther away from the motor to let it run free. WTF do they design it this way. I coundn't use the plastic spur's full teeth width, only 4/5 width is contacting the pinion.

The fact is, Losi designed the plastic spur so wide that it almost get conflict with the mount, but that extra width can NOT touch the pinion, it does not work together with the pinion, which is what it was designed so wide for. Is that logical ?

Yesterday I managed to run my 8ight 2.0 E conv, finally. It did run great but I just can't say it was a perfect design.

littlejohn 06.22.2009 08:09 AM

I must be plain lucky, but I had the 45T metal spur but got the plastic one for a quieter ride and have had zero probs... no rubbing or anything..

after reading your post, i just went and looked at a couple of my plastic spurs.....they don't all seem to be exactly the same width. I wonder why this is?

Still, if you get the RCM mount, you'll have zero issues with rubbing on the chassis as it raises the center diff a few mm and i don't get any rubbing on the mount from the spur either. I run 45T with no problems at all. Not only that, it's an awsome mount that allows you to gear as high or low as you want. that's one thing that no other 8ight conversion seems to offer right now.

Edumakated 06.22.2009 11:33 AM

The plastic spur definitely does not fit. It is too wide and the only way to get it to fit is to shim it away from the mount or sand it down.

However, if you set your mesh correctly, the metal 45 tooth losi spur works GREAT. It is nearly as quiet as the plastic. I have found that the metal to metal is loud if you set your mesh too tight, but just fine if you loosen it a bit.

You also have to dremel out the plastic hole covering a little bit as the spur may rub.

Other than that, the Losi kit is pretty nice. I like it in my 8t 2.0. Very simple to install and pretty solid.

i have to use them because i run my center diff almost locked....basically with putty in it.

when you have that much pressure in there, geared the way i do, i blew a dime sized hole in the stock one. these are incredibly strong. I got one for all 4 of my 8ights. a good investment imo.

I run those cups in the front and rear diffs of my 6s powered lst. I have not had issues with them. Nova rc makes a pretty good product.

It depends on what you're doing. i'm all about high speed, high acceleration street runnin' so 50K weight didn't do anything but make my front differential "diff" out constantly. it felt like i was running a loose slipper is the best way i can describe it.

i went all the way up to 350,000wt and it still wasn't doing crap for my front diff, so i started using playdough in the center and leaving the front and back at the stock weight...that got me the results i wanted.

if you're gonna be doing alot of dirt track/off-road racing, just follow what the manual says and you'll be fine. if yomu're gonna be doing alot of parking lot stuff, i recommend using putty or playdough in the center or it's gonna feel like you're just spinning your wheels with no power.

stum 06.22.2009 10:15 PM

I think the trick to getting this part to set right is in how you get the bearing on the spur side to fit.. what I mean is there is play on the bearing so it moves back and forth just a little bit, if you don't get it perfect into the CNC mount and then kind of pull it out slightly and into the front mount it will not fit properly as you described. I have an 8ight-e 2.0 sitting next to me and it fits just fine using the losi kit and it doesn't rub at all. I would suggest investigating how that bearing is setting (even or not) and you will find that it will work ok for you when you install it correctly. Now I do know you can't use the plastic bearing w/ the tekno kit as the spur rubs into the bottom so you would need to cut out an even bigger spur drop which really isn't worth doing. I really wanted to swap to the plastic spur, but I decided to just hold out w/ the stock steel 48t. I absolutely love how the 8ight-e 2.0's sound w/ the plastic spur gear installed (my brother has one) :)

Yes, the RCM mount is what I am planning to invest.

Losi's mount is so thick that I can NEVER install my pinion like the way you did in you picture.
the Losi mount's center hole is so small that most of my mod 1 pinions can not be used because they have bigger bore(the untoothed section), like this one:
http://www.rc-monster.com/forum/atta...1&d=1245736253
Also, the RCM mount allows the motor to move horizontally when adjusting mesh, making it much easier to make a motor rear end brace.

DwightSchrute from this pic it looks like you are using the Losi motor brace, how did you make it work together with RCM mount when adjusting mesh ? the mount moves the motor horizontally but the brace supposes the motor to move in a slope according to the losi mount ?

medusa'd maxx 06.23.2009 06:11 AM

can you run the heavy duty steel supports in the nova cups or are the spider gear axles supported in the right place?
I've got Nova bits on my maxx and they are bullet proof - hard to order from OZ though

i'm not sure i'm understanding your question. are you asking how the top brace that is over the spur gear still fits with the RCM mount?

if so, the rcm mount has a spacer that goes under the front mount so it levels out the front and rear mounts to be the same height so it really dosen't have any effect on how the motor is moved when meshing. it also raises the center diff some because the rcm mount is a bit taller than the losi mount. i hope that answered your question.

or are you referring to the black "L" shaped plastic that goes under the losi mount? if so, you don't need that piece anymore when you use the rcm mount because their taller and allow for more clearance for the gear. i have since taken them all out of my 8ights. I imagine if you used both you might manage a 48t spur, but i'm not sure.

i haven't tried the HD supports in the nova cups so i'm not sure if they would fit or not, but the cups are machined to perfectly hold the spider gear axles in place. as long as you regularly change your diff fluid, they ought to last just short of forever.

Playing with fire here... Losi has good products, but I would not say they are the best available. You might be able to say that if you have owned everything out there... I will say that the rcm mounts are the best I have tried, better than the losi mount I have.

i just don't get the losi mount at all. it was a poor poor design imo. that huge bump severely limited any pinion over something like 16t or so. i even modded it so i could use bigger pinions, but even then it was severely limiting.

here's the before and after:

http://i247.photobucket.com/albums/g...t/HPIM5871.jpg

RCM mounts rule! :party: :yes:

SpEEdyBL 06.23.2009 06:03 PM

If the rcm mount would allow you to keep the same center diff height as stock, requiring you to add your own spacers for spur clearance or dremel the chassis (right now it forces you to raise the diff about 5 mm from stock and the motor 5 mm higher than it needs to be) then i would reinvest! Lower CG rules! I like to have a competitive edge to my stuff!
