Check this page out for detailed info on the sticky collective issue on the blade. Be aware that horizon has released an upgrade to the blade around the middle of september that introduced a 3 ball bearing blade grip that helped to remove the issue. If your manual has an insert in it that includes info on this upgrade then you don't have "the" sticky collective. It could be something else.
