Recently I’ve been really into modding XTs.I turned this one into a fixed axle and it plays really well!
There’s a hardware store right next to my house that I popped into and grabbed some plastic spacers that I cut just a hair shorter than a C bearing; About 1.5mm off. I used a zinc screw+bolt and added the rubber O-rings to add a bit of weight around the center and the rim.
It weighs about the same as a butterfly but plays much lighter. As soon as I want it to return I can just relax my play and the string gets caught nicely in it’s hang time.
