Good points, megazone. The g-maxx chassis is near bulletproof, and aluminum bulks are highly recommended. If you are bashing and will likely sustain some hard hits, the Proline maxx suspension is the toughest I have seen. If you hit any aluminum arm at full speed from the wrong angle, it will bend or break. For bashing, the Proline is the toughest suspension I have seen (I have broken a few rpm arms, but never a proline arm). I run aluminum on my trucks, but I seldom bash (mostly a racer). Aluminum arms can take quite a hit, but you will likely bend the hingepins often!
