What is a Slipperential?

Teflon bushings
gaskets(possibly o-rings as well)
diff out drives(pending new out drives will fit typical bones better and last longer, but this is still a wear item)
Slipper pads
End caps(increased shaft angle will accelerate wear here - Losi 8 front for example)

The current outdrives accomodate a 9mm dogbone ball - this allows them to be used on the HPI Savage bones(and a few 1/8 truggies) and also "works" on the more typical 8mm bone. We are working on a harder, lightened out drive version with an 8mm outdrive bore for the more typical 1/8 center shafts. "one size fits all" was the intention initially. We are working on tweaks and will continue to do so. We are working on shimming scenarios for fitment in some larger diff openings, as well as other enhancements. The product will be tweaked and updated throughout is life, as every product is. :)

thx Mike

hi, do i need to loosen the screw wen i tighten the slip diff? It seems that i strip the screw holding the adjusting ring

If you are stripping the retaining screw on the adjustment nut, you are probably tightening it too much. The thrust bearing removes the twisting force from the nut in use, so it will keep its adjustment pretty well(tested it without a cinching nut, actually). You only need to "snug" the adjustment nut screw to retain the setting. If you use threadlock on it, use a very small amount. You must loosen this screw to make adjustments, and snug it back down when adjustment is complete(this is in the instructions that came with the unit and linked by brushlessboy16). :)

Yes but now I must figure a way how to remove d screw:(

Looks good Mike, bet you are glad to finally get it in the store...

The slipperdiff is between 30-40 grams more than a plastic diff/metal spur depending on the size of the spur.

The HandyRacing crew made the trek to the iHobby Expo in Chicago two weeks ago, and we were very lucky to find Monster Mike himself manning the booth at the show. Mike is really "the MAN" - he even let us film an on-the-spot no practice or planning interview to tell us and our viewers about the Slipperential.

THANKS MUCH, Mike!

Hmmm, I dunno how to make the YouTube block quote work I guess.

If your gearing, batteries and motor are correct for your vehicle can having the slipperential too loose and slipping too much cause the battery wires to overheat and melt a little?

Definitely not!

The only thing that will overheat in that case is the actual slipper on the slipperential.
Slippers should slip then grip. If it slips too much, it will heat up rapidly & cause the slipper to fail & require replacement.

I don't believe your set up is correct.

Wire heat generally indicates that there is too much load on the motor & it's drawing a lot of amps.
Keep that going & you could potentially have a massive failure of both motor & ESC.

What motor are you running with, what gearing & in what car?

Also, are you running on grass that is half the height of your wheels? My mate did this with his MT & fried a motor & MM ESC. Initially we thought the motor wires had just gotten hot & melted the solder enough to separate, but, after fixing that & trying to run again we discovered everything was shot.

my setup is a 40 x 82 mm 2000kv motor, 4 cell A123 batteries and 14T pinion in a Muggy.

Is it a Leopard motor by chance?

You're right about your set up, it sounds just fine.

If I were you, I would try a different motor.
I heard from a guy that bought a Leopard motor (not saying yours is) & it heated up the wires & was running well within it's limit, but, it ended up frying his ESC for some reason. He has never discovered why nor has had the opportunity to run a different motor for testing on his now toasted ESC's.

Just some ideas I thought I should throw out there.

It is a leopard motor but the motor doesn't really get hot at all. I dont have the money for another motor but can possibly try it sometime in the future.

Well, funny you mention the motor never heats up, this guy's motor never did either. Just the wires.

Perhaps you have a mate that could let you try one of his motors?

If you use it & the wires don't heat up, you know where the problem lies.

Good luck with it.

Hot wires could also be caused by other issues as well. Bad solder joint, lose connection, or maybe you have a nearly invisible short some place. Make youself a list of possible causes and go through your entire system one by one (simplest first) until you run into the likely culprit. Swapping out equipment may not always be the most viable solution, but it is the easiest way to eliminate components one by one as the problem. If you try another motor and things still heat up, than the motor is likely not your faulty link in the chain.

I dont have the money for another motor :( I can go through and look for bad solder joints though.
