 Stan,
 
 I waited until I had run the engine on the airframe before designing the
 panel.  I am very glad I waited.
 I highly recommend waiting.
 
 After considering Dynon, Advanced Flight Systems, Grand Rapids, etc. I ended
 up deciding to go with dual-screen Garmin G3X.
 I actually flew out to Steinair and spent several hours playing with the
 various systems side by side before deciding.
 
 I eliminated all vacuum instruments and instead installed a "z-14" dual
 electrical system.
 
 I used three 2.25 inch round gauges in addition to the two glass screens.
 
 Of course the airspeed and altimeter are mechanical.
 The attitude indicator is electronic (tru-track), but has its own backup
 battery.
 Spend $3k more and you can get a mechanical AI, but I chose the less
 expensive route.
 
 I did my own layout in turbo-cad, which is attached.
 
 I bought the entire package from Steinair and had them wire the entire
 system.  They also
 cut the panel inserts on their NC router and did the lettering for me. Took
 about six months from
 initial discussions to delivery.
