According to the Walmart sub posts, the Motorworks sub seems to be a fave, back in Ottawa where I used to live, it was hard to find those subs because the stores were at the other end of the city and I had to spend a few hours just to go there and come back, didn't really bother going anyways.... I am now converting a plastic sub kit to RC. RC crafts are my lifeblood, I don't know what I would you without them!
