The Ultimate 10-300, designed in the mid-1980s and flown in the 1988 World Aerobatic Championships by aerobatic legend Gordon Price, quickly became one of the most recognizable and respected biplanes in aviation history. Its bold design, compact proportions, and unmatched agility set a new standard for high-performance aerobatic aircraft—inspiring both full-scale and R/C pilots around the world.

Building on the success of the Ultimate 70cc, World Champion Quique Somenzini has taken everything that made the 70cc extraordinary and elevated it to a breathtaking new scale. The Ultimate 120cc brings the spirit of Gordon Price’s original design into a new era—combining the unmistakable presence of the Ultimate 10-300 with modern aerodynamics, advanced construction, and unmatched convenience.

The Ultimate 120cc features Flex Innovations’ proprietary Speed-Lock system on the top and bottom wings, stabilizers, and canopy—allowing for quick, screw-free assembly without the need for tools. Whether you’re assembling at the field or preparing for transport, Speed-Locks make setup effortless, secure, and precise. Constructed from the top down to withstand extreme G loads, the Ultimate 120cc is constructed with carbon fiber and laminated plywood that makes the airframe extremely lightweight yet rigid. On top of the modern construction, the Ultimate 120cc features bold Clint Sweet Designs color scheme providing the Ultimate 120cc with standout presence.
The Ultimate 120cc embodies the essence of Flex Innovations — authentic scale looks, modern innovation, and Quique Somenzini’s visionary design unite for the ultimate expression of Power, Precision, and the Purity of Flight
