Well here go's. I built this e-revo from the ground up. It is the third that I have built and all the parts are brand new. I have a brushless system running a 16 tooth pinion and a 65 tooth spur. The problem is that even at half throttle the slipper clutch is screaming. If I tighten it down all the way it is still slipping like crazy, and kills the bearing. Because it is slipping so bad it is not even as quick as my brushed revo.
 
slipper pads good? i'm assuming that they run the same slipper set up as the 3.3....
 
Ya the pads are brand new and I even changed them just in case and it didn't make a difference.:\
 
The disc may be shot. It would have to be really shot to not lock up though. Your not supposed to tighten the new slipper setup all the way. If you did once, you'll have to leave it locked because the pressure plates are probably crushed. It would either slip like crazy, or be locked. Did you sand the disk clean before installing the new pads?
 
I've tried a lot of different thing and nothing seemed to work. So I just ordered a e-maxx double disk. A little modding and I think that will be a better setup.
 
Try taking the spring off and using the two spring washers that the nitro has. If that doesn't work then maybe you should gear up. 16/65 is really low gearing. Maybe 18/56 or 17/56 will allow your clutch to hold all that juice. A double disc system sounds cool but your driveline will pay for it.
 
Not sure how much higher gearing will help as that will just make the torque->forward momentum ratio worse. I had a similar issue on my savage and had to gear down to keep the slipper from slipping. Even though the engine has the power to gear taller, the extra torque required caused the slipper to slip constantly.

On a side note, I just picked up a slayer roller and it had a busted slipper pad. Even my 2.5R was causing it to slip excessively. My LHS didn't have a rebuild kit, so I kind of sat there and tried to figure out what I could use until the parts show up.

I had an old t-maxx brake disk laying around. Oddly enough, it's almost a perfect fit in place of the slipper pads. I had to round out the holes a hair for the little locator pegs on the pad holder to fit. I roughed up the pad and cleaned it with DA (had old oil/gunk on it), drilled out the little holes a hair and rounded out the inner hex a bit (even though it fit as it was) and threw it together.

Without really tightening it down, I was attempting to gauge the grab factor of it in my hands (had the trans out). I locked the spur shaft with an allen and tried to twist the spur to get it to slip. It grabs very very well. I took it out and ran it and now my slayer will pull a wheelie!
 
You make a good point on the gearing Olds. I remember driving my real car with a burnt clutch. I was ok till I hit 4th gear, then would slip excessively. No wonder you got guru of the year.
 
I bought a e max double slipper and bored it out to accept the stock traxxas e revo slipper clutch bearing. I over cut the slot to lock it to the transmission and it pulled through lucky there is two sides to try, will let you know how it go's.
