A few years ago, that was called C fan, not AC fan. What did i miss, what does that "A" stand for?
Whenever i enter the fan it tilts and goes crooked almost immediately... how do i stop this? ~Jammy7797
Your string is probably rubbing viciously on one side of the cup during the entry, which causes the diabolo to tilt. More speed to the diabolo will help slightly, but the best is to figure out why (and where) the diabolo tilts and work to fix that problem.
