RANS S-9 Chaos

The S-9 Chaos has been in production since 1986. A stock S-9 equipped with a Rotax 503 47hp engine is potent enough to compete in sportsman class aerobatics. S-9's have been equipped with up to 100 hp engines with spectacular results. With full inverted capability, a Chaos can achieve advanced aerobatics. As with all RANS kits, the Chaos comes welded and pre-fabricated, reducing assembly time and increasing precision.

The S9 Chaos powered by a Rotax 503 has wing and header fuel tanks, a four point harness plus lapstrap, and open cockpit with optional canopy.
