convert Losi 8B 1.0
 

What all do I need to convert a losi 8 1.0 buggy to brushless? I already have the roller, MMM combo (2200), so I would assume all I would need would be the RCM motor mount, a standard mod 1 5mm pinion (how many teeth?) an some straps for the battery right?

You need the motor mount battery tray and straps.

try a 13t pinion

if you're interested, here's how i did my conversion:

will the 45t plastic spur for the 2.0 ft the 1.0? will a standard 5mm bore mod 1 pinio work?

none of the plastic spurs fit. they're too thick. you need to sand like 1/8" off of the face for them to work in the center diff. why losi used these thick spurs, i'll never understand.

the other alternative is to buy the steel 45T spur. that'll fit with no mods.

yes, a standard 5mm bore pinion will work.

EDIT: losa3552 is the part # for the steel spur.

what is the stock spur with the losi 1.0? Will it work with the RCM? It looks like you are using the RCM and the plastic spur?...

i think the stock spur on the nitro rtr is 47 or 48. but in the conversion, you have to turn the diff around and run it from the other side and that limits the size of the spur unless yopu cut a slot in your chassis. so basically without modding the chassis, 45 is as tall as you can go.

i started out with the 45T plastic spur. i just sanded it down to make it as slim as the steel one. the next 5 8ights i bought, i just went with steel spurs to save me the headache of having to sand the plastic spurs down.

EDIT: i use the RCM mount on all my 8ights.

Look into the Tekno and Losi conversion kits too. Makes everything much easier since they just mount right in.

if you go with the tekno conversion you'll have to use long bore pinions and you can't really gear for super high speed as i think the tallest i've seen was a 17 or 18.

also: even the losi conversion comes with the ultra thick plastic 45t spur and their mount is horrible imo. the rcm mount just allows for a much wider use of pinions.

so with the RCM the biggest I can use without mod is 45t. Ok. Does it come with instructions? LOL

also, what gearing would be good for racing (offroad) with the 2200 on 4s?

you won't need any instructions. once you get everything it's really self explanatory. as far as gearing, a good place to start seems to be right around 45/12-13.

you could also use Brian's speed parameter solver to determine it as well:(depending on the size of the track most gear it from 37-42mph

so the center diff is mounted in reverse?

not to be redundant, but I want to make sure I have everything. I need:

-motor mount
-battery tray and velcro straps
- kyosho 45t plastic spur
- 13t mod 1 5mm bore pinion

anything else?

the kyosho spur does not fit
it is also too thick.


I tried...

stick with the steel one, and get an rc-monster pinion and its not loud at all

yeah, but what is the biggest spur I can use? The stock one (i.e. the one that is on it now, I think a 48 will work with the RCM mount?

The stock steel 48 spur WILL work with the RCM Mount.
Direct drop in. NO MODDING or GRINDING. I dont know why the dwite guy said it wouldnt. I am running it right now...:whip:

sweet. thanks. I was wondering why it wouldn't

can anyone confirm that the stock spur does or does not work?

Since i've never tried to fit a 48 on there and have only gone on the word of dozens of other menbers who've said 45 is the biggest on a stock chassis.......here's a close up photo of my 45t spur. look at the chassis and the gear. do you really think i can get 3 more teeth?

what spur are you using? THe kyosho will fit? I want to order now but am getting confused...

Kyosho has a 45T? I always thought it came only in 44T and 46T.

ok, 46t. I was confused. Do you know if the stock metal spur works, as you can see, we have conflicting opinions, also, will either of the kyosho spurs work?

I am saying YES because I HAVE it INSTALLED and have run it like 10 times no problems....

Did you add the metal spacer under the plastic diff brace? it raises the center diff by 1/4" or so and now clears chassis prefectly

yeah, i put the spacer under the plastic brace. if you say a 48 fits, then i guess it fits. i just wouldn't have thought so after running a 45. i guess most other people who did the conversion just stuck with the 45 the conversion provided.

I am wondering, are there any instructions or tutorials for the RCM conversion? I a unsure how everything mounts up...:neutral:

4 screws on the bottom 4 on top....it's that simple. really. this conversion is as easy as easy can get. are you the same brushless moose from the traxxas boards?

yep. So it just directly replaces the center diff mount?

i'm vxlrocket from the traxxas boards...i hung out mostly in the rusty forum, but i remember you from the revo forum.

to answer your question...yeah. exactly. you'll see once you get everything. any issues, and any of these guys will walk you through it. i'll even take one apart and do a pictorial of the build if you need it, just let me know.

i know you had a revo, right? weren't you the original thread starter of the fastest revo contest?...the 8ight is 1000 times easier to work on. i literally needed no instructions.
any questions, just ask away moose! :yes:

cool. Yeah, I traded my revo roller for this 8ight roller. And yes, I was the starter of the biggest traxxas thread to date, the fastest revo challenge. a pictorial would be great. I also heard that on the 1.0 people were tearing up diffs like crazy. Is that true?

only the diff cups. the insides are fine. if you get the 2.0 diff cups they will last just short of forever. nova-rc also used to make aluminum diff cups, that i run in all of mine but the 2.0.

I havn't heard of that problem b4. My diffs have been truckin for 6 months now and i havn't seen any signs of wear on the gears. altho if want to upgrade anyway u can get heavy duty housings but the stock ones should hold up fine.

1. do the losi 2.0 diffs drop right in?

2. Does the RCM mount come with screws to mount the motor in the mount?

3. Do have to drill my chassis at all?

4. Do I cut the radio tray?

1. yes

2. yes

3. no

4. yes...it'll take about 10 seconds with a dremel. 3 minutes with a micro-saw

the 1.0 diff cups are a little weak over 90. i blew a dime sized hole in mine after abnout 4 runs.

Oh, thats understandable :lol: yeah i've never been over 90 b4 :whistle:

I dont think i'll be going that fast unless my 8ight gets hit in the a$$ by a jet.


so, there is nobody who has a writeup on how to install this?

here's what i did:

http://www.rc-monster.com/forum/showthread.php?t=20559

to install the RCM mount just replace the rear plastic nitro mount with the RCM mount. then, place the small bar looking aluminum spacer under the front plastic nitro mount to make the mounts even. everything else is self explanatory. this build dosen't take any more than about 30-45 minutes, max.

this is literally all you'll need to know....the diff goes in between. you can see the spacer in the front mount. that's it for the motor mount/diff. don't worry about it dude, it's an easy build. :yes:

match that with my pictures and it should all make sense.
