Way back in the 70's I had a Kraft KP-7Z that had crossed trims. They were located at the top left and right top of the transmitter case. I thought it was a great feature and could never understand why no other manufacturer, except Pro Line, had the same feature.
With the Pro Line sticks and the electronic trims, not mechanical trims like most used, it was the smoothest, most comfortable TX I've ever owned.
