Van's unveiled their first-ever high wing aircraft a EAA AirVenture Oshkosh 2022. It drew huge crowds all week. Portrayed, at least for now, as an outback flying machine with big tundra tires, RV-15 has a very large interior. Could it be a four seater one day? It sure looks like it. With more than 200 horsepower up front and a voluminous capacity, RV-15 definitely breaks new ground for the world's largest kit aircraft producer.
