Today I finally got the RC8 Center diff today. It came brand new in package and just like everything thing else 1/8th I was surprised by the size. After a few minutes of just messing around and building it I decided to try something that I had heard may work for the Center drive shafts. This is one of the only issues that I was worrying about with this project was finding some center drive shafts that would fit.I got the tip from brushlessboy16 (Who is now my new best friend
)that I can cut down Revo axles to replace the input shafts on the center diff so that I could use sliders. I was curious and realized that I had some Revo axles on the buggy already since the Revo and Slayer use the same axles. I figured out it would actually work and started hacking away. They ended up fitting perfectly with some modification . I know that sliders don't show up in the racing dictionary but they are cheap, more "Traxxas" like, and they fix my problem of trying to find correct length Cva's that fit on the Revo diffs. Here is how I made the modifications to make the sliders work on the Rc8 Center diff.
1.First I had to shave about 1/8th inch off of the black plastic part where the axle hooks on to the sliders.
2.Then I spent about an hour and half using my hand saw to cut down the axles so that they where the same length as the Rc8 inputs.
3. That's about all there is to it after that I just started putting it back together.
(Right is stock, Center is cut-down, Left is the completed one)
4. Once you have it put all together it should look like this.
The diff mounts fit perfectly around the axle coupling so that the pin doesn't fall out.
And the diff in the mounts with the top plate..
Over all I was very surprise how well everything to fit together.As far as shafts go I just used the Slayer Sliders off of the front of the buggy. I figured I can get a set to replace them off of ebay because the Slayer sliders fit perfectly.
