N66UN is a Van's Aircraft RV-6, a single-engine piston aircraft operated by WILLIS ROBERT L. SkyMeter has tracked 40 flights totalling 44 hours of airtime via ADS-B. The most frequent segment is 2J9 to 2J9. Service window in our records spans 367 days. Of those flights, 6 (15.0%) carry at least one detected incident: a go-around, unstable approach, stall warning, or runway excursion. The Van's Aircraft RV-6 has a maximum takeoff weight of 1,600 lb, light wake category.

About the Van's Aircraft RV-6

The Van's RV-6 is the aircraft that proved homebuilts could outperform factory-built designs while remaining accessible to amateur builders. Introduced in 1986 as Van's first side-by-side two-seat model, the RV-6 became the best-selling kit aircraft of its era, with over 2,900 completed worldwide by the early 2000s. Designer Richard VanGrunsven created a low-wing aerobatic tourer that cruises at 200 mph on a modest 150-180 horsepower Lycoming engine, faster than most certified aircraft in its class, while retaining docile handling and short-field capability. The type's clean lines and constant-chord wing deliver a cruise efficiency that still impresses decades later.

Built primarily from aluminum using riveted construction, the RV-6 takes an experienced builder roughly 1,800 hours to complete from Van's full kit. The design is stressed for +6/-3 G aerobatics, making it equally at home practicing loops and rolls or flying cross-country trips at 75-percent power. Its 200-knot never-exceed speed and 165-knot max structural cruise speed give it a genuine performance envelope, while approach speeds around 65 knots keep it manageable on shorter runways. The RV-6A variant, introduced shortly after, features a tricycle landing gear instead of the original tailwheel configuration, accounting for roughly half of all RV-6 family builds.

The RV-6's success established Van's Aircraft as the dominant force in the kit-built market and spawned an entire family of RV designs that now includes over 10,000 completed aircraft across all models. Its combination of speed, economy, and builder-friendly construction made it the template for the modern high-performance homebuilt. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
