why no slipper clutches??

[mk351e]

Doesn't anybody want to protect their $300 motors with a slipper clutch? Does anybody make one for a 1/8 vehicle? Or does anybody know of a way to make one?? I was looking through RCCA mag last night, and noticed there was a 4wd RC10 ad (w/ a BL) that had one on the center diff. Why can't I have a bigger one for 1/8??

Probably because most b/truggies use a center diff. There was talk of a "slipperdiff" a while back (IIRC, Cadima was doing something with it), but not much lately.

Besides, I always thought a slipper was there more to protect the drivetrain/gears rather than the motor.

It may be more for the gears, I dunno. I never really quite "got" the concept of a slipper anyway, and by the time I was old enough to get it, I didn't care about rc anymore. Then I got older, married, became a dad, and now I play with 1/8 scale stuff. WOW am I cool!

I'm waiting for Mike to make his. I know my MBX5T with the Mr. C conversions uses a slipper clutch. I took it out though to go with a higher tooth count on the spur.

Speking of protecting the drivetrain what ever happened to the "Slipperential" that Mike produced? From what I have read he made only one or two, but nothing since. I also read about it in one of the RCAction Mags, but have never seen it since. Was it not a good idea? Or was it just too much for production? Just curious what happened to it?

I hope Mike can make his slipper system soon. Here are some links that shows Mr. C's slipper: http://www.radiocontrolzone.com/show...3&postcount=95, http://www.radiocontrolzone.com/show...&postcount=150

I hate slippers. I glue my pads to my spurs and tighten the bejeesus out of the slipper for no slip, any time I have the slightest amount of slip it just melts my spur gears. As for protecting the drivetrain- if it needs protection it's time to upgrade.

Yo Brian, been awhile. Love the avatar by the way. Slipper is coming, and so is a bunch of other sweet surprises.

Anyone who wants to know what's taking so long needs to try and make a one first, then you'll get it. you also need to do it when you're not working which is all day everyday, and keep the ole lady and kids happy at the same time! Alas, the design is complete.

You dial this slipperential in (note Mr C's little toy looks more like a slipper or ball differential, not a slipperential), and you will see what it is like to have control of extreme power. I have more hours on the track with the slipperential than anyone alive and I can confirm the following benefits:
1) life of the driveline including motor and diff gears are extended by attenuating impacts on the driveline. Everyone who puts a hating on their truggy or buggy has experienced the dreaded snapped bone, busted or stripped spider gears, bend cvd shafts, popped motor rotor, etc. Slip from any slipper heps this. But this one can take the pain and not melt down or give in like others. And it packs it all tightly in a single rotating mass that offsets the rotational forces the motor puts on the chassis when it spins. This also keeps everything low down on the chassis and makes room the other accessories.

2) Picture yourself at the track and the conditions are packed and dusty. You can only lay down so much power. The faster you're going, the more throttle you can lay down. But out of a corner or a sharp turn you must hold back on the juice or she'll break loose. A dialed slipperential takes just enough bite off of the torque to smooth out the low speed launches, and when exiting a turn power-on. Sure you can screw around with programming the ESC and try and soften up the launches but the consequence of this is you soften up the throttle at all speeds. That can make for some ugly landings when you a trying to clear a triple. Also, you lose speed and time on straights since your power is blindly being trimmed regardless of the traction. If you don't take the time to dial it in just right, you won't see the light.

In short, it gives more durability and that missing degree of freedom in adjustment you don't have on a brushless conversion.

Cheers all.
