The Cabrinha RC-412 Free Spirit is a light aircraft produced by the Cabrinha Aircraft Corporation of the United States. Within the International Civil Aviation Organization (ICAO) documentation, the aircraft is assigned the type designator FREE and is classified under the L1P category, which identifies it as a single-engine, piston-powered landplane. Due to its size and classification, it is categorized within the light wake turbulence category (L/G).
Technical data provided by ICAO Doc 8643 establishes the basic physical dimensions of the RC-412 Free Spirit, noting a wingspan of 8.2 meters and a total length of 6.1 meters. While the ICAO documentation includes a field for the maximum takeoff weight (MTOW), no numerical value is provided in the publicly available summary for this specific model. Beyond these dimensions and its general engine class, further technical specifications—including cruise speed, service ceiling, and fuel capacity—remain undocumented in available aviation reference materials.
Information regarding the production history of the RC-412 Free Spirit is extremely limited. There are no verifiable records concerning the specific years of manufacture, the total number of units produced, or the exact location of the production plant. While some records associate the "Free Spirit Aircraft Co Inc" with Huntington Beach, California, in relation to RC-412D and RC-412-II variants, there is no explicit confirmation linking this specific entity or location to the Cabrinha Aircraft Corporation and the RC-412 Free Spirit model.
Regarding its design, the identity of the lead designer or design team for the RC-412 Free Spirit is unknown. It is important to distinguish this model from the CEI Free Spirit Mk II (also known as the Cabrinha Model 423), a three-seat homebuilt aircraft designed by Richard Cabrinha. There is no documented evidence to confirm that the RC-412 Free Spirit is a variant of the Model 423. Consequently, the first flight date and specific design innovations for the RC-412 remain unrecorded. The aircraft saw no documented military service and operated exclusively within the civil general aviation sector, though specific operator lists are unavailable.
