Questions?? 2wd Slash slipper clutch question

Howdy, I have a 2wd slash that I recently converted for racing in open class. Run a 4600kv Castle motor w/ Momba ESC. Having difficulties with the slipper tho, no matter how I set it (tight/loose) it seems to be slipping nearly all the time. To keep the motor temps down I use a 17t pinion and 90t spur combo, is this a good combo? The pads get glazed no matter how the slipper is set. I have the top speed to keep up with everbody else. I've checked into Robinson clutch but the largest gear I've seen with that is a 72tooth spur, is there any others? Any advise would be appreciated, Thanks.

I had the same kind of issue. What I did was mildly scrape the clutch pads to get the finish off them before you install. I also run mine w15/90 to keep the heat down; it still gets "warm" though after about 8-10 min.

Sounds familar, I installed a fan on my motor also. I've tried lightly sanding the pads also, but get the same results.

Oh yea!! The fan knocked down the temps about 20-30 degrees!! Purchased an Integy fan and it did the trick. You might have to trim some of the cooling fins to get it to fit under the trans case tho.

Here are some more pics, it's an Integy fan set-up with a "cowling" that I made with 10mil lexan. Both might be available at your LHS, if not I got the fan off ebay.

Another option would be to ditch the entire Traxxas slipper and get the STRC layshaft that allows you to use the Associated slipper/spur assembly. A lot more consistent. I also got the STRC motor plate which was another big plus as the heat generated from brushless motors (especially Castle ones) can quickly warp the plastic motor plate; hence stripping your spur. If you're racing Mod, these two things will help.
