Experience extreme 3-D flying at its best! On low rates, she's smooth, graceful and precise, capable of performing a FAI pattern sequence with finesse. With a flip of the duel rate switch, she transforms into a fire-breathing 3-D monster performing an entire range of full-stall thrust vectored maneuvers with authority. Torque rolls, Waterfalls, Harriers, and High Alpha Rolls, the Obsession 3-D ARF™does it all!

The Obsession 3-D ARF is a 120 size 3-D airplane that is a thrill to fly. Its oversized double beveled control surfaces deliver precision response, and the extreme throws you need for even the most difficult maneuvers. The Obsession 3-D is jig built with laser cut parts for accuracy & precision. Its lightweight all wood built up wing and airframe help the Obsession 3-D with its agility and ensures you're flying unlimited in any direction. Inside you'll find a fiberglass cowl and wheel pants, swept aluminum landing gear, and a complete hardware package. We've topped it all off with premium covering for a sharp looking finish.

Like every Goldberg ARF, The Obsession 3-D ARF is 90% prebuilt and quality hardware components are provided to make assembly a breeze. We believe you'll agree, the Obsession 3D ARF is one of the most responsive, in-the-groove aircraft available!
