Carter PAV

When the CarterCopter was damaged in 2005 due to a gear-up landing caused by pilot error, the cost of repair was deemed higher than the cost of making a new aircraft with the added benefit of incorporating lessons learned from the first aircraft. Design of the PAV was begun during 2005."{{usurped|1=[https://web.archive.org/web/20060311031802/http://www.cartercopters.com/weekly_update_archive_2006_1.html Archive 2006]}}" Carter Aviation, 2 January 2006. {{usurped|1=[https://web.archive.org/web/20120229051756/http://www.cartercopters.com/weekly_update_archive_2006_1.html Mirror.]}} Retrieved: 7 August 2010.

The PAV has flight characteristics similar to other Carter aircraft. When stationary on the ground, the engine powers up the flat pitch rotor to 370 RPM, and the engine is then disengaged from the rotor to provide full power to the propeller.
