Once I was done with the battery boxes, I worked a bit on the tranny. I wanted to set up the slipper even though I still don't have the motor plate and mount.
I will try this Hot Racing double slipper with 6 stock slipper pads at first to see if it works. If it doesn't then I will make an aluminum slipper disk like what I am using on the E-Revo. The Hot Racing slipper looks very nice, fits extremely well and has less wobbling than the stock slipper assembly.
I took 4 Traxxas screw pins and grinded them down to use with the RC Monster drive cups. The Traxxas output shaft has two flat spots and a hole and I wanted to use that to secure the drive cups which have two threaded holes for grub screws.
So the screw pins will go in the drive cups and rest against the flat spots of the output shaft with the small pin part I left in the hole. It should be very strong.
One last pic.
