Where does it work....
 

I was just thinking that it would be nice to have a place where people can list what vehicles they have installed the slipperential into, how it fit, and if any mods were needed to make it work. It should be pretty universal in size and drop right into a large majority of vehicles, but I'm sure it will take some minor mods to make it work well in others. So when you get one installed post up here with some pictures and any useful information that others running that same vehicle might want to know. An easy place for others to be able to look and see where it works and how.

I'll Start. :mdr: Installed it in my RC8T tonight. It dropped right in, no mods needed. It has a smaller 46T spur gear vs the 54T stock gear or the 50T optional RC8T gear I was running so I needed to drop a tooth in the pinion to get the overall gear ratio back to the same as it was before. I will probably be looking for the optional 50T slipperential gear once its available.

(Camera batteries are dead so I'll post some pics of it installed later tonight or tomorrow once I get it charged up.)

EDIT: Was just looking it over a little closer and saw that it actually was just slightly rubbing the center diff top plate. I just shaved the side of spur gear slot in the top plate down ever so slightly with a hobby knife and its no problem. Just something to look for if you put one of these in a RC8T.

Some quick speculation tells me it should fit in all Ofna Hyper series, Jammin cars/trucks, and Losi 1/8 should be fine. It likely won't fit in XTM stuff (XTM diffs are a tad longer), or the SH Z-Car (this buggy uses a shorter diff). Other than these, I dunno.

It won't fit in a Kyosho M9 either, it also uses a smaller diff.

Yep. Not a chance.

It should work in Mugen, AE, Xray (808 may requre raising the diff mounts since stock gearing is 42T,but any of the older ones and the XT8 No problem), Caster, Losi.

What about the ST RR? I know ofna hyper diffs have the same dimensions as the ST RR diff case.

See post #2 :smile:

I see two things. Is the front bearing fully seated in the diff mount? i tlooks like its is not.

Also there is some wear in the output cup to the front, you can see the Pin from the cvd sitting low in the slot.. Are the outputs hardened?

Yep the bearing is fully in. Nope, no wear on the outdrive. It hasnt even been run yet.

Mike will have to answer the hardedned outdrive question, but if I were a betting man Id say it is. Mike doesnt typically cut corners like that.

The AE(and many others) simply have their bearings protruding from the bulkhead - it will fit all the vehicles mentioned so far in this thread with some shimming needed for the Ofna and older Kyosho and HB stuff(which use larger diffs). It won't drop into the MP9, which has very small diffs - would need slight mods to make it work.

The out drives are hardened - if they weren't, they probably wouldn't make it through a single race. The cvd drive pin is what is worn in Jeff's picture.

Will it fit in my Matrix TR with out any big issues?

Will this fit the Traxxas E-revo?

It will not...

I better start saving.........that's $300+ including freight for me, damn exchange rates :whip:

damn hope it's worth it, it will save d motor n less heat?

Probably no difference in heat. but yes it will save the motor from hard impacts

It's not so much saving the motor (though this is more of a concern with 1/8" shafts), but rather saving the drivetrain from sudden stress like landing a jump under throttle or going over a bump that causes the wheels to spool up for a second before catching. Stuff the would normally cause a shock in the drivetrain get's absorbed.

This system does exactly what a slipper clutch does, but the slipper and differential are all in one, compact, strong, weight-saving unit. Usually, to get both a slipper clutch and a differential you end up with a transmission, which is much bulkier and heavier (and has more rotating mass) and has much more weak points and areas that can fail. Any number of the gears in the transmission failing = loss of power. Any of the pins holding the gears failing = loss of power. Transmission case flexing resulting in gear mesh failure (and stripping of gears) = loss of power.

Any of the above failures which could occur in a transmission just simply cannot occur on a slipperential since it doesn't have those parts to fail.

If I m not wrong it's with a 46 spur, my CRT is with 62 spur will it still work in my CRT? Wat spares shld I buy for the diff thx

You could use it in your CRT if you convert over to the CR buggy mount and center bulkhead, otherwise you might not get the pinion to mesh with the spur. In fact, I am using the CR buggy center diff unit on my CRT.

:yipi: GTP here I come!

So I must buy d cr center diff mount. Any other mod I need to do? So the slipper diff comes with 46 or 50t?

It comes with a 46T right now. 48T, 50T, others(?) will be available later.

should I wait for mike to make the 62t diff?

hes not going to. Just use the SPeed calculator to compensate with your gearing.

This is correct - no plans to make a spur this large. I have a 50t spur in the works now. 46t and 50t will be it for a bit - these should cover most applications well enough with the appropriate pinions.

Is the 50 in store now? I can't wait man

Any ETA for the 50T since it's in the works now?

It seems like everyone is asking will it work in this truck or this buggy. I'm not speaking for Mike here, but I think the truth is "theoretically" it should work in most 1/8 vehicles that use a converntional center diff. But I don't think its actually been installed in every vehicle on the market yet. That was the point of starting this thread. When you get one and install it, post up here with some pictures and some notes on what if anything you had to do to make it "fit" in your vehicle. There is bound to be some minor modification needed to make it fit in some vehicles and it will be a direct drop in for others. The intent of this thread was to start that database of what vehicles its been put into and what was needed to be done to make it work properly. An easy reference place for others to look.

People who have already ordered them or are ordering them soon will probably start getting them installed this week. Make sure you guys keep adding to this database of "Where does it work"

hi, the CR center diff holder is shorter can I still use d CRT motor mount?

Unfortunately not, unless you do heavy modifications to the motor mount (but even then it still might not work).

so if I understood wat I m reading I can't use this diff with rc monster conversion?

Hi Mike,

Need ur help here I m getting confused, it seems that I can't use this slipper diff in my converted CRT? I m ordering for a converted Losi8T too. So before I order now. Do u think it will work for these 2 cars?

You can use the Slipperential in the CRT, but you will need to buy the Jammin' X1-CR motor plate, and X1-CR center bulkhead. Then you will need to make sure you can gear your motor properly with whichever spur gear you choose (I would recommend you use the 50t).

Thx man, can this diff be used for losi8t?

Sorry guys, wats the exact model or link of the cr buggy mount? Btw I need to change d center diff mount not the bulkhead rite?

Btw does mike sell only d motor mount? I hv d servo plate already

Mike doesn't sell just the motor mount separately as far as I'm aware.
You will also need to change the steel posts that support the center bulkhead to the shorter CR ones:

this is quite a expensive convert, I need to change d center diff mount, motor mount n diff almost us$200 over :(

Alan,
The Slipperential will drop right into the RC-Monster X1CRT mount (mount was designed to accomodate smaller spurs as well as the large stock spur)and can be used - it will need to be shimmed to take up the extra space(Ofna diff is a little larger). There is no need to switch to the CR motor mount to use the Slipperential. Only the 46t spur is available at the moment, though - so this needs to be considered into the gearing equation. It is a good idea IMO to replace the ring and pinion gears on the front/rear diff to the newer truggy ratio, but with the appropriate motor, battery nad gearing it is not a necessity to use the slipperential (50t spur is suggested for this application, which is in the works). :)

thx Mike, I m looking forward to the 50T n spread the news to Singapore.

hi Mike, what rings I need to change?

Actually - the opposite of what Chris said - install the new truggy ring gear and matching pinion to the front and rear diffs (x1 has buggy ratio diffs and a large spur to make the overall reduction). Also, the buggy pinion won't work on the truggy ring gear and vise versa. You would need to swap both gears on both diffs.
