I'm sitting here with a pile of avionics boxes and the completed upper forward fuselage (not attached to the plane) trying to figure out the best way to locate each (G3X system with blind com2, VP-X, and blind transponder). It seems clear that I'll have to cut an opening for the GTN650 in the sub panel due to length of the box with connectors. The actual panel faced instruments are not a problem but the ADAHRS, engine monitor box, various other components look like a jigsaw puzzle. Any photos showing where others have placed these or similar? Advice?
