see how it flies with the blades loose... kind of hard to advise without seeing how loose they are in person. I'll tell you this, there should be no up and down play at the base of the blade, where it screws into the blade grip. But they need to be loose enough (moving side to side) so that they straighten themselves out when you spool up.
Also, try to tighten each side about the same.
