one of the reason is because of the parts support and local sevices. Actually hk ppl is strongly relied on the parts support from mk/kws instead of web order, however there is a lot of spare parts no matter from hpi or oem manufacturer can be ordered from web, as well as ABC, and i found a lot of foreign forum is still discussing cup racer because online shopping is their usual habit !
Not popular here I believed :
1. Part support (as discussed).
2. Not run as goods as the others out of the box.
(Building skill is an important elements for this chassis but sadly we here have many choice of
run-well-immediately chassis).
