I'm presenting here my aircraft - The P180 Avanti II. This is an upgrade of the original XP9's Avanti.
Main features:
Flight model within 10% of the real aircraft (as per manual)
Real autopilot operations
Many SASL-driven functions
Full compatible with X-Plane 10 64-bit
Full modeled 3D cockpit with lot of maniplulators
