Recommendation to all owners of Saitek / Logitech yoke.
Thank you so much for providing the solution.
I followed the recommendations, purchased the board and cables.
I just finish the modifications which were easy to follow.
What a difference. not only eliminated the dead zones but it is so smooth and even in all axis. It is a pleasurer.
Real flying for 40 years, now gives me the pleasure to be much closer to the real thing.
For a small investment you get yourself a totally new yoke.
