Put one pair of clips onto the center tube. They should drop all the way to the bottom. Pay special attention to the direction of the q-p holes, they must match the photo.
Put the servo mounting plate onto the tube, servo side down, on top of the pair of clips.
Put the tensioner onto the tube with the nub locking into the matching hole on the servo mounting plate.
Turn the center tube until the hole in the tube lines up with the tensioner screw. Turn the tensioner screw into the hole of the center tube.
Add the other pair of clips, making sure the q-p holes are in the same order as the first pair of clips.
Snap the retaining ring on to the end of the assembly.
Attach the arms to the clips. They are turned 180 from each other.
