I am currently trying to get the pivot ball mod working in my 120. I have tried it in my MSR and it has reduced the pendulum effect quite noticeably. I shortened the flybar arms as well. It now flies, I feel, the way it should have from the factory. The 120 has taken a little longer, I am using the ball out of my original SR swashplate. The main shaft size is the same as the 120. I need to find some small O rings to hold the ball in place without getting in the way of the movement of the flybar. I tried an old pair of dampeners out of my SR but they are to chunky. Need to locate some thinner ones. I also shortened the arms on a flybar but made the mistake of removing too much material from the center hole of the flybar. This has to be able to just fit over the pivot ball. I have a little too much play so I think I will pick up another flybar and give it another go. Hopefully will find some O rings this weekend. Will post back when and if i get it flying right.
Later
