Development
Van’s Aircraft designer, Richard VanGrunsven, designed the RV-6 series as a two seat side-by-side development of the RV-4, which was itself a development of the single seat RV-3.
Market demand motivated VanGrunsven to design the RV-6 and offer it as an optional nosewheel design. The original two seater RV-4 has been a remarkable success, but the tandem seating configuration was not considered ideal by many potential owners as it leaves the passenger isolated in the back seat. Many female spouses of builders especially favoured the side-by-side configuration over the tandem arrangement.
VanGrunsven worked diligently to create a side-by-side design with a generous 43-inch-wide (1,100 mm) cockpit that did not sacrifice the RV-4’s handling, STOL performance and especially its high cruise speed. In the end the RV-6 prototype produced cruise speeds that are only 3 mph slower that the RV-4 with the same engine.
The first RV-6s had a forward hinged canopy design. This was a simple one-piece arrangement, but it made taxiing the aircraft with the canopy open more difficult. Later kits had the option of a rearward sliding canopy that could more easily provide ventilation on the ground.
The RV-6A version features steel rod landing gear with the nosewheel strut attached to the engine mount. The nosewheel is friction castering and the aircraft is steered with differential braking. The brakes are mounted conventionally on the rudder pedal toes.

Famous quotes containing the word development:
“Dissonance between family and school, therefore, is not only inevitable in a changing society; it also helps to make children more malleable and responsive to a changing world. By the same token, one could say that absolute homogeneity between family and school would reflect a static, authoritarian society and discourage creative, adaptive development in children.”
—Sara Lawrence Lightfoot (20th century)
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“I’ve always been impressed by the different paths babies take in their physical development on the way to walking. It’s rare to see a behavior that starts out with such wide natural variation, yet becomes so uniform after only a few months.”
—Lawrence Kutner (20th century)
