RE: What is this?
I don't care about being cheep. If I wanted to be cheep I wouldn't be in RC. What I asked is "are they recommended" not "are they worth it." Big difference. If I have to put $1000.00 to get something to perform the way I want it to, it's worth it, to me. To me it's not about money, it's about fun.
I'll get off my soap box now (wasn't trying to but now you know where I'm coming from) and I'll ask again are the ball diffs "recommended?"
