I just finished my XV-02 build last week, and ran my first race with it on Thursday. I hadn't really looked online for replacement or hop-up parts until after I built it, but I noticed that there's really not much available for the chassis compared to my TT-02 and that makes me a little bit scared to race it in case I break something. Tamiya doesn't even offer an aluminum steering upgrade, which seems weird since the steering parts seem like the weakest link. Why is that? Is it just because it's a relatively new chassis? Or have sales been lower than expected? Should I be worried? Makes me wonder if I should have gone with the XV-01 instead.
