Hi everybody,

I think one can build a complete glass cokpit avionics system starting at 1
000 $ and not more than 3 000 $ for a fully doubled complete version.

I've started an open source project :
http://openavionics.sourceforge.net/
http://sourceforge.net/projects/openavionics/ (downloads)
so every body can take plans and build his own system.

The bad news is it won't be ready until 2/3 years.
