Slide the balancing clip on the trailing edge of any blade, halfway between the holder and tip. They actually work like an oar which is used to row a boat. Simply add products to your 'My project' & submit a project request. Repeat with each blade, noting which one most reduced the wobble, then slide the clip in small increments away from the center of that blade. Adjust the blade pitch to the left to pull air up.
