I picked up a conversion kit on eBay a few months back that adapts T Maxx wheels to the Rusty. It was $25 shipped. Comes with way longer front spindles, a piece of tubing to slide over them to keep the hex's where they belong. It also came with pins and aluminum clamping hex's. I run 2.5 T Maxx tires on my Stampede with 12-87 gearing. Xl5/12t. It's slow and handles like crap. It drives like there's more unsprung weight then sprung. Probably is! Looks cool, though and my little cousins like it because it's almost as big as a Maxx. I modded some Duratrax Nitro Mt hubs for the back and some old megatech touring car hubs for the front. Aluminum. The kids hit more stuff with one pack then I have in the 10+ years I've had it. Nothing's broke yet. I also put T Maxx turnbuckles on 'er. I leave the slipper locked and tell them to hold it wide open off of jumps. It front flips if ya don't. I can't believe they haven't blown a driveshaft off or killed the diff or a spur. It's a vxl tranny, but I'm still amazed. It goes through mud pretty good. That was the main reason I built it. Just to get it wet.
