I`v race on a set of X-3000 pink
feel like Bk bar`s
good forward bite a bit less side bite (compared to taper pin`s)
X3000 now has a low profile taper pin carcass
This is the biggest change
Any driver can copy a great set up, a Champion however will steal it .
If Jesus returned as a Rc car he be a Rc10 B5M
