Hi everyone,
I have a simple question with regards to the Exec Glass instrument panel which is listed for $31,490 as part of the EX-3 kit.

My understanding that a builder can either choose from existing 2 options on the web site (20k and 31.5k) or build his own panel from readily available components.
The Executive Glass panel by Cubcrafters includes G3X-$4000),Probes (pitot/AOA)-$450,GTR200-$1450,GTX335-$3625 and intercom -$300, harness, switches, breakers.
The total cost of the components above is around $11,000.

My question is - what constitutes the difference (~$20,000) between cost of the components I listed above and the final price of the panel? Is that labor/margin or I missed something?
