Optional Brake Disks? - RC-Monster Forums

Mike, Any idea on timing for when the brake disks that fit the slipperential outdrives will be availble?

optional brake disk? Izzit for slipper diff? Need brake servo?

jhautz · 03.30.2009, 09:18 AM

OPTIONAL. For running mechanical brakes if you choose to.

I should have the optional brake discs in a week or so if all goes well. Timing will be pretty close on the 50t spur as well. :)

so wait, you mean the outdrives arent just like standard 1/8 stuff? shoot, i was hoping to get mine setup today when it gets here. are they similar? can my brake discs be modified to fit easily? how are the outdrives different?

btw, what type of brake discs will be avail for the slipperential? those rc8 style discs with the fiber coated aluminum are probably the best discs i have used.

Just about every different brand had different shape outdrives for the brake disks. They arent standard shapes.

The brake disc kits I will offer will fit the included out drives. Most 6mm diff out drives should work in the Slipperential anyways, so you could most likely install the diff out drives from your existing diff and use the disc brakes from the kit as well.
Note - "most likely" - I obviously haven't fitted all the major out drives to verify fit, but the diff out drive is a pretty standard diff out drive, so a HB, Kyosho, AE or Ofna diff out drive will most likely work. :)

sounds good. be sure to post when your discs are available? what type of discs will they be?

oh ok, i thought they were all the same. i use the same discs for my AE, Mugen and Losi and they all fit the same. i just figured there was like one popular main shape that was used by most of the manufacturers. i am pretty sure my slipper. will be here today so i will try some different thigns to work.

AE, Mugen, and losi outdrives do not fit in the slipperential. i got mine yesterday and it is quite the engineering feat. well actually the AE outdrives look identical but the hole location on the outdrive for the pin to go through is in a slightly different location on the slipper. outdrives and so when i tried to use the AE outdrives you cant get the pin thru. actually funny thing is it works on one side of the slipperential but not on the other so i guess technically i could have run just a single brake disc going this route. i decided to use my dremel and just make some brake discs which worked fine but then the slipperential didnt fit in my RC8T. the center diff top plate hits the adjusting ring about 1/8" before the top plate rests on the mounts so this didnt work. i looked at just cutting out a large hole in my carbon top plate to make it work but the size of the RC8T top plate is such that doing this would leave a very small amount of carbon for the sides of the top plate, if any at all, and i worry this will weaken the top plate too much to work.

does anyone have a solution to all this? has the slipperential been used in a RC8T with mech. brakes? what vehicles has it been used with a mech. brake setup? it appears that this will be the case with other vehicles too cuz my Mugen center diff top plate sits at the same height and the losi center diff setup is much shorter than the slipperential diff. just wondering what vehicles are others using where this is just a "drop in" fit? i really want to get this to work. in fact, it seemed the slipperential was probably gonna be easiest to make work with the RC8T so my plan was to just make all my other truggies able to use the RC8T center diff mounts and top plate with the slipperential. i figured this would be best since it was mentioned that to use brakes it has to be a brake setup where the linkage runs on top of the center top plate, as opposed to one over, one under. the RC8T has this type of linkage whereas my Mugen and Losi do not.

at this point i am planning to just make a larger top plate out of some carbon i just ordered but i am just wondering if there is any other approach to make this work that i am not seeing.

Pics might help if you can...

ok cool. i will try to take some tonight and post them.

I have the slipperential in a RC8T. I havent tried setting it up with mechanical brakes though. How would putting the disks on the outdrives effect where the slipperential contacts the top plate. if you go to the the first post in the "where does it work" thread you can see it installed in my RC8T. I did note that I had to take a small amount of material off of the top plate , but it was a very small amount. I didt even need the dremel, just used a hobby knife.

Yes, pictures would help. I read your post 5 times tryuing to figure out what you mean and I cant understand how the mechanical brakes would make a difference yet.

yeah, the brakes arent affecting the top plate issues. maybe i am doing something wrong. i will try it again and take some pics here in just a bit. did you take out material on the underneath of the top plate or did you just make the spur gear hole larger?
