The much anticipated RANS S-21 made its debut yesterday at Sun 'n Fun after being delayed by Tuesday's storm. The S-21 is a departure from RANS' standard practice in that it is all metal. The basic structure is a welded steel cage with an aluminum skin. Aluminum panels are attached to the cage and each other with pull rivets going into match-drilled holes.
The S-21 project started out with plans for the use of the Titan 340 engine, but there was so much clamor for a light sport version that the plane now has a Rotax 912 ULS engine. A version with the larger engine should be ready well before AirVenture.
