GENIOUS!

I love it!

One thing to note with the G50 is that it is very sensitive to the twisting motion required to go across the gate (left/right)

In the standard setup, if the rods are not aligned, they can tend to slightly twist when being pushed forwards>backwards, which makes the H uneven and shifting difficult.

You have 2 arms attached to the selector shaft on the trans, one for in/out, and one for left/right....(the left right one being the one with the tie rod) Im not sure if you pinned the left/right to the shaft, or used a key. If you pinned it, there is a possibility that you may get a very small force on the "tied rod" as the in/out lever moves the shaft in/out, which might affect the shifting.

Perhaps look at keying this connection so that the in/out movement is completely isolated from the left/right (i.e. so that the left/right arms stays still and the shaft moves in/out of the end of the arm)

I keep thinking about this concept, and cant wait to see one in action.

If you can make it work, I want one.

Have you thought about making the selector levers like a yoke, with a bearing?. Firstly, to reduce friction, but also centralize the forces on the lever and avoid any flexing that may be encountered with a pin system + lever on the side.

Obviously the paths milled into the wheels would have to go all the way through, and may need to be modified slightly so there is enough meat left...
