Align Linkage Ball Set - Trex700E/ Nitro Pro.

I bought this set of ball linkage to improve the pitch geometry for the BeastX. At step J, pitch geometry, I was getting a red light. Used the smallest linkage at the blade pitch link to improve it, but I am still at the red light. But before the light was turning blue at 7.5 deg, but now it is going blue at 6,7deg. I think it is a improvement at a low cost.
