This Airplane is the LX7a It is basically a Lancair 4P pressure vessel with completely redesigned wings and tail, and a modified belly. They cruised at 277 Knots with three men, gear and over 200 gallons of usable fuel on board, flying lean of peak at 23,000 feet.
This is our friend Eric's design. His company was promoting their new Lancair 4P modification but didn't have any models to attract a crowd. We happily offered our services.
