Very unlikely the -400 will be ready by Christmas. It has a crazy amount of programming involved. Not to mention a manual that will probably turn out to be about as thick as a Harry Potter book. The -200...I'm optimistic. Once Theo and I get through our current workload, we're going nuts with the -200. I've got my documentation from the UK, finally, and once the Saab is done (by the way, we're adding some custom programming to it using Gizmo!), we're rolling into the 747 and Hawker 4000 stuff.
