Redbones,
Thats cool you made a slipper spool. I would like to see this as well. Good thinking
. I made a modified spool that uses 416 delrin cups and sleeves to help reduce chatter and to reduce weight. But it requires a modification to the diff housings to run. So I'm not going to use until after TCS races. I would like to try out what you made though, it could be like a tunable spool!
Here are some pics of the spool I made
