Hey guys

I ran my 44.1 for the first time as part of the first race of our indoor local series. Last time I ran 4wd electric was last millenium

The stock spur has an obvious high spot, but I can uld live with that. Typical AE spur junk

The rear gearbox started developing a "tight" spot at the end of the 5mns of practice i ran the car for. I didn't have time to wrench on that the whole day as I was running both 2wd and 4wd the whole day, so I ran it like that, knowing it was suboptimal but hoping it would hold. It did but I spent most of the day tightening the slipper run after run, as the nut would unscrew all the time. Again, I haven't checked what shape the o-ring is in, but I suspect it's gone. During the last round of the A, which I still managed to grab, the spur ended up letting go at the same time as the slipper which went completely loose (bye bye o-ring).

had one of the local top dogs help me set it up with the diffs early in the day but obviously I did sthing wrong about it. I can set up a diff/slipper combo pretty well in 2wd, but 4wd was a bit of a new thing to me.
HEre's my Q - is there something special to do to this slipper to make it work, or to actually prevent it to work at all like mine did?

Thanks
Paul
