Here’s another cool little trick from friend Leon Luke for a 700n DFC. You can center the elevator A-arm perfectly by rotating it upward and resting it on the upper bearing block. The inside of the “A” will rest on the outside of the upper block and automatically shift the arm into a centered position. From there just insert your allen driver down through the upper main bearing hole and tighten the set screw down. Good to go. Thanks Leon! – Nick
