What is a fair estimate for the high-end of avionics on a future build, $50k?

With the 750 you'd be pretty close to budget 40K for equipment, extras like servos and install kits, lights, alt/reg, switches, breakers, antennas, harnesses, coax/connectors etc. etc. do add up, so a 45K budget should cover most everything if you do all the labor yourself.

Of course not everyone goes for the full enchilida up front, provisions for the second screen and a GTN650 would save you over 8K initially.

I placed too much emphasis on the 750 being able to control the transponder, though this is convenient since my 750 is com1, nav1, and to a degree, communications control central. The more pertinant point is that the panel mount GTX345 is itself fully available and controllable in the event that the G3X OR the GTN750 are lost. When everything is working traffic and weather can be displayed onthe G3X, the 750, the iPad,and even the iPhone.

The best redundant systems are those that lose the least functionallity after a single point failure. I?m comfortable with the remote com unit as com2 controlled by the G3X because com1 IS the 750. I was less comfortable with the remote transponder because, with a single G3X, control of it would be lost with a G3X failure. Walt?s panel, with dual G3X?s and backup battery, has added redundancy, but at the cost of considerable weight, panel space, and $$. The G5 is essential to redundancy in my setup, but it is a real gem.- Otis
