Started bending the provided drag links bracket to fit the contour of the rotor profile and to get the 2 brackets eactly parallel, where it attaches to the rod ends. Spent an easy 3 hours making very small adjustment to get the correct distance between the brackets. I ended up using a small washer, as shown in the picture, whch is perfectly fine. Once I was happy with the shape of the brackets, it was time to drill some holes to attach them to the rotor blades.
