standard hyper 7, 46 tooth, 13 bell. the screws in the front were loose the first time then i rushed the second set in there not knowing how much time i had before the main, which wasn't much. i got it put together, slapped on some tires and was next to run, i had the buggy qualifier a bit before then, marshaling duties and then starter box hunting for the mains. i was gonna redo the diffs this week anyways to try something lighter for the next state race next month. if you look at my profile in rcsignup you'll see my race days always end in dnf's. poor maintenance on my part. the funny part is when i take the truck out to practice i can run all day. when race day comes and i check and recheck everything i can't get 10 minutes out of it. coincidence?
