The RV-14 is the most recent design from Van's Aircraft, and is essentially a slightly larger RV-7. It is intended to be a little more suitable for cross-country, while still retaining some of the sport aerobatic elements of the RV-7. The aircraft is a traditional all-aluminum construction and available in both tricycle gear or taildragger configurations.

Van's is one of the largest kit manufacturers, and you see RV's everywhere. Furthermore, they have an almost cult-like following of builders and pilots, which is one of the main attractors to building one. The Van's Air Force forums is generally very active, and a great source of feedback and information.
