  The Rio Claro Araponga (Brazilian Portuguese name for the Neotropical bellbird), was a single-seat sailplane of high-wing.
  
  ## Design and development
  
  In 1983, a group of aviators from the Rio Claro aero club decided to hire Sílvio de Oliveira, an aeronautical engineer, to develop a high performance monoplace glider. Initially it was planned to build two copies, the resources were pooled among the members. With classic lines and entirely built in native wood, with a plywood outer cover, it had conventional landing gear flaps formed by a fixed skid and a fixed roller, semi-embedded on the fuselage and fixed skid under the tail.
