The König SC 430 is a compact, three-cylinder, two-stroke radial engine featuring single ignition, primarily intended for use in powered paragliders and single-seat ultralight trike aircraft.[1] [2]
Initially engineered and manufactured by Dieter König in Berlin, Germany, this engine design was subsequently transferred to Zanzottera Technologies based in Italy. Later, the entire two-stroke ultralight engine lineup, including the SC 430, was acquired by Compact Radial Engines located in Surrey, British Columbia, Canada.[1][2] In August 2017, Fiate Aviation Co., Ltd. from Hefei, Anhui, China purchased Compact Radial Engines. As of 2021, Fiate Aviation did not list the SC 430 among its actively marketed products.[3]
Development
The SC 430 stands out as a distinctive three-cylinder radial powerplant that combines a very small footprint with a lightweight construction, weighing just 17 kg (37 lb). It incorporates a single capacitor discharge ignition system alongside a Bing 49 diaphragm-type carburetor and utilizes rotary valve induction. During its last production phase under Compact Radial Engines, it was supplied without a reduction drive; however, the earlier Zanzottera version offered an optional cog belt reduction drive with a ratio of 1.75:1. The engine is started exclusively with an electric starter; no recoil starter option is provided.[1][2][4]
Previous models delivered 24 hp (18 kW) at 4200 rpm, equipped with a slide-type carburetor and reduction drive. The Compact Radial Engines variant is rated at 20 hp (15 kW) at the same rpm. The recommended time between overhauls is specified as 300 hours.[1][2][4]
The SC 430 shares identical bore and stroke dimensions with the larger four-cylinder König SD 570 radial engine.[2][4]
