When I took over the management and maintenance of the 172 I used to fly,
the original turn coordinator installed in the panel in 1976 was still in
the plane. By the time I stopped flying five years later, we had put two
new ones in. Same design from the same company. Workmanship is as important
as design.

Much of the resdesign you talk about is intended to make workmanship less
important in the quality of the final product. It certainly does that. No
matter how good or bad the workmanship is, the product is still a piece of
crap!
