The RV-6 was the first aircraft in the popular Van's RV series to feature side-by-side seating and the first to offer a nosewheel option.
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.
Later kits had the option of a rearward sliding canopy that could more easily provide ventilation on the ground.

The Nigerian government's Aeronautical Industrial Engineering Project (AIEP)[4] searched for a suitable trainer that could be assembled in Nigeria using local labor and selected the RV-6A.
Three prototypes were constructed as a proof of concept using a combination of consultants (Peter Lewis from the USA and John Cook from Great Britain) and local labor, subsequently EXP-1 was the first Aircraft to have been assembled and flown in Nigeria.
