What would it look like to have two G5s and a portrait G3X? I have a backup G5 in my -14 with 10" G3X and it works well but I never use the G5. In the -8 I was thinking of having a pair of G5's, upper for attitude, lower for HSI. I want the G3X though for the engine and charts. So what if I put a stack on the right of autopilot control, audio panel, and GNX375, two G5 in the middle, and the portrait g3x on the left (or vice versa stack left, G3X on the right). How does that G3X look in portrait for showing engine monitoring and charts without having the attitude indicator showing? Has anybody done this?
