I was wondering the same thing? I'm also trying to figure out how you're snapping axel stubs? I realize stuff can just happen, but you said its happened 3 times. That's just too coincidental. I've had 3 Redcats with those same stubs and a friend also has one. We've never snapped an axel stub. I ran my Tornado S30 on the street with low profile street tires and did some serious cart wheeling due to the short wheelbase. Is it possible something is not right in your front end. Is everything tight when you replace them? How are the bearings, are the axel stubs moving in and out? I just can't imagine 3 of them just snapping off without something else going on that your not seeing.
