The RV series of airplanes has been extremely successful, and as of November 2019, about 10,600 RV kits had been completed and flown, and thousands more are under construction. Completion rates currently average about 1.5 per day,[2] making the series the most numerous of all homebuilt aircraft. They feature responsive controls plus good speed and fuel economy.[3][4][5] In 2013, the company announced it would begin selling assembled RV-12 model aircraft as well on a limited basis.[6]
