I made a 2 inch crossmember of 1/8 inch aluminum to fit right into the "Radio Stack" and screwed it into the stack screw holes. I just used an old Loran tray as the template, bent the ends at a 90 degree backwards and then matched the screw holes to the tray holes. That gave me the flat surface to mount the base plate to. I wanted it to be removeable and not alter the panel.
I'll probably go with the AirGizmo once they are released just because it will clean up even more. But I gotta tell you, I am spoiled with being able to swivel and tilt the iFly quickly and easily. I'll post pics if I change it. The AirGizmo should be in shortly. They said they should receive the final shot sample this week.
