Ok, so I guess the lipos are fine, huh!!!

Yep, they seem quite happy in there.

So Mike, could you make it work for us with E-Maxx 3905 and FLM chassi?:yipi::party:

I am sure i could and I will- but it won't happen tomorrow. :)

That OK mike Friday's fine - we're not impatient ;)

but in the future, sweet Mike

Thursday would be better for me...

I keep coming into this thread to look at that mount. That is RC pr0n pure and simple.
That mount, slipperential + Savage= sexy goodness lol

Seriously tho... still holdin onto the nitro in my XL as I piece things together to convert. I really don't want a locked tranny, don't want to go full flm, and a slipdiff would be perfect. Put the motor going forward, and stuff the back w/ batts. Booyaa.

So this will drop into my SC8?And will it work in my GTP?

It will work fine in the SC8 - the GTP uses a funky 19mm bearing, so finding an 8x19mm bearing will be the challange. I think using an 8x16 bearing with a 3mm press-in delrin ring (bearing spacer basically) would be the easiest plan of action for the GTP. The GTP will likely ned some shimming as well, nbut this could be done in one shot by building the shim into the bearing spacer. :)

I was just going to replace the diff braces in my GTP... If I can find some with a similar bolt pattern it would be nice, otherwise a little drilling doesn't bother me. Does anyone have an idea what would be a suitable replacement?

Post up the hole spacing but maybe close to ofna lx

The front is 18mm wide, the rear is 11mm, and the holes are centered L/R. *Edit* Would this bearing work? It's 6mm wide, is that extra 2mm going to be a problem or is there a need for lateral shimming?

Easier to just get these.

Are those 5mm width? Do you know the end-to-end length of the slipperential (inside the bearings)? I swear I've seen it mentioned but I cant find it again...

Mike

I just don't want to be a pain in the...., but

Do you think you will have the mount for the FLM 3905 E-maxx chassi in this summer?

Best Regards

Fits XT8!
 

The slipperential fits the XRay XT8 truck perfectly, no mods required at all, direct drop-in (mikes chassis brace installed)

i just destroyed the stock tranny in my twin force. I think I am going to try and install this in there. I will post the results. Any foreseen problems?

Cool, it is a good news for me. I ordered one.
Now just to wait the rx8

just installed mine in a rc8t and street tested it.......niiiiiiiice!!!!!!!!!!!!!!!!!!
can't wait fir practice this weekend

Anyone race with it in a jamming CRT x1?any review?:)

I have been trying to figure out how to get shorter outdrives on the slipperential because they hit the steering servo mount in my 808. Mike mentioned that he thought the HB outdrives might work, but I ust tried them and they didnt. They work on the small cover side, but not on the large cover side. Its just a little to tight to get the cross pin in the hole. Strange that it works on one side but not the other.

What I did make work was the xray diff outdrives, but I had to replace all of the gears inside with the xray gears to make the outdrives work because it uses a different size cross pin thru the outdrive shaft for putting the crown gear on. It also needed to have a bunch of extra shims added to make it work.

I used all of the metal washers/shims that came with the slipperential, and then used all of the washers/shims that were in the xray diff too. So basically 2 shims behind each of the 4 satelite gears (1 xray washer and one slipperential washer) and then I put both of the xray washers that go behind the 2 larger crown gears behind the crown gear that went on the small slipperential cover side allong with the washer from the slipperential. (1 slipperential washer behind the crown gear inside the large cover, 2 xray washers and 1 slipperential washer behind the crown gear on the small cover side) I hope all of that makes sense. It seems to be a perfect smooth mesh now. I tried adding more washers to see when it got to tight and if I put more than this in there anywhere the mesh got to tight inside.

Heres a quick pic with the shorter xray diff outdrives and the xray internal gears installed. I think it should be good. Not exactly a cheap change to get shorter diff cups, but if you already have an xray then you have all of the parts from the xray diff to make the change. In the 808 you basically need the shorter outdrives because if you use the longer ones the outdrive hits the steering servo mount and you need to take quite a bit off just make enough clearance.

Anyway, just though Id post what I found to work.

Xray outdrives insatlled with xray gears shimmed up. Slipperential outdrives sitting next to it for length comparison.

Mike, do you have any schedule on when you can have a bracket for the 3905 FLM chassis to work with the Slipperential:party::yes:

Best Regards
E-Maxx Sweden

or for the 3905 stock chassis?

Thanks a lot for the info!

BCE MBX5T chassis - had to slightly dremel the spur gear hole, and the nut on the slipperential collar . both by about 0.5mm. 1 minute with dremel.

why the diff has those pesky o-rings inside like mugen diffs do? Most people dont use them anyway :)

Hey mike.
 

I hope you are still planning to make more mounts for the 3906 as well. I need a few of them for my projects. One for the new Maxxler chassis that Matt is producing, one for my extended FLM Maxx, and one for the extended UE Lightning SuperMaxx that I have setup for high speed testing.

what diff oil do you use in truggies for racing? in nitro i used 10k, in my center diff max I had 20k so I put about 17k in mugen and it seem too much. i am bit afraid to go down to 10k.

Ok, installed it in my Losi 8eight-T and it's almost a drop in.
Only thing that has to be taken care of, at least if you're using Mike's motormount is the fact that the spurgear will be touching the motormount.
3X 0.3mm shimms on the side of the spurgear will solve that problem.:yipi:

@Mike: My packaging was not damaged in anyway but the 3rd pressure plate was missing. If I understand your instructions right you need 1 pressure plate under the thrustbearing, 1 above, and 1 on the slipper side which need to be roughened a bit to allow for more grip. Used one from my stock but I was wondering if this happened to more packages...:neutral:

Anyway, it works now and I promptly killed my Castle MMM again....grrr:whip:

Sorry about the missing pressure plate, Steeni. I am glad you had something similar layong around. The slipper side must be scuffed up a bit and also must be one that is included(they have cutouts that engage the slipper side endcap to prevent it from spinning). The 2 plates on either side of the thrust bearing are to provide a surface for the bearings - any washer in this size is fine here. :)

Np, as I said it's working now.
But I would say that the scuffing of the pressureplate on the slipperside is a must, the slipperential did overheat badly after roughly 3 minutes on the track before I actually read the instructions again :oops: and saw the remark about the scuffing.

Yep - the pressure plate is pretty slippery before the scuff procedure. When properly assembled, it works very well and has good adjustemnt resolution. :)

BTW, anybody seen the slipperential on rccaraction.com?

It's even in the forum under the "hot news"!

Well done, Mike, congratulations. It came a long way, I remember when we first statred to talk about a thing like this, must be a good 4 or 5 years ago now...

Daf

Has anyone used it on a Caster F8T?

Has anyone here tried the slipper on a D8? If so what did it take to do so? Pics would be nice:yes:

Mike?

It fits the Caster truggy - I will let people know what is needed to install it into the D8T when I return from IHobby next week.

just an example of shimming needed for an RC8b with RC-M conversion kit.

Could someone please give me the Diameter of the adjusting ring and the distance from outside to outside of the bearings? With this info I could determine whether or not it will work in my application!
Thanks in advance.

32.75mm from outside to outside of 8x16 bearings. About 41mm OD on the adjusting ring, including the slight protrusion of the adjustment screw. :)
