RANS S-12 Airaile

The S-12XL Airaile went into production in March of 1990 and has enjoyed a progressive evolution. Improvements to cabin comfort, durability, and performance are the direct result of working with user input. The Airaile was designed to fulfill requests for a two-place pusher with side-by-side seating that was economical to buy, quick to build, easy to fly, and rugged enough to withstand the rigors of training. The Airaile only requires a two-car garage and common shop tools and skills to complete from start to finish.
 
The S-12S, "Super Airaile" is based on the S-12XL series. Changes made to the S-12S include a lower cabin and engine mount height. The result is less frontal area and a lower thrust line. Headroom is still more than adequate and will accommodate pilots up to 6ft 6in. Dacron coverings were replaced with traditional dope and fabric. To adapt the new covering system, mods to the wing and tail included new ribs all around, plus leading edge wraps for the wing. The total effect of the mods brought about an increase in cruise, climb, glide ratio, and a lower stall. In the air the handling is improved in both roll and yaw.

Build time for the Super Airaile will be on the average 200 to 300 hours more than the XL, but still within reason. Most builders should complete the plane in 6 to 12 months. This is due to the tremendous amount of pre-fabrication and precise fit of our parts. Quality airtime is built around a kit that is designed to be built by the first time builder. A good manual is at the center of fast build times.
