    E-revo Drive Cup

    Ok, so I recently bought the E-revo 2.0 Limited and I have to say it is the most powerful RC I've ever driven nevertheless owned. Though with this power comes some unintended consequences. For example, I recently noticed that my drive cups (rear only) have started to get really worn out. Like I said, the car is fairly new and only has roughly 8 hours of drive time in it. I've been looking at these as they are the only actual CV joints I've seen for the E-revo (all other ones are just U joints in disguise). I want the axle to be light so it won't put a lot of stress on the drive train. Do you guys have any good Ideas? What do you use?

    The drive cups get chowdered no matter what you do. In my experience, And with the cost of them I don't bother with it

    When I check diffs. I'll swap the drive cups from right to left and then eventually put the rears to the front.

    Ok, Thanks for the advice. Do you think that the wear causes extra friction? I spray a WD40 dry lube formula on them basically every time I run to hopefully eliminate extra friction as my motor doesn't have a cooling fan or anything on it right now and it gets pretty hot to the touch. I always seem to have squeaking coming from the drive cups after about an hour of driving no matter what though.

    Got a feeling the ones your linked to are for the v1 brushless revo. Also, they still have a dog bone on the end your trying to minimize wear on, so it likely wouldn't help anyway.

    I did what Acidic01 does. I switch the left/right ones as they wear and get a new pair on order for when they are notched badly and need replaced. Been running mine for a year on 6S with the same set of cups on it. I got it used, so I did flip them once, just not sure when. I haven't replaced any of them with new cups yet though.

    The ones on the link I posted do use the cups but they are a better grade of stainless steel which should resist torture more. To be honest I was really interested in the fact that they were propper miniaturised CV joints which typically have way better properties over U joints.

    The noise may be from the a arm hinge pins they make a sqeek for me. Dry lube those and your pivot balls
