Development
The SC 430 is a unique three cylinder radial engine that is very compact and lightweight at only . The engine features single
capacitor discharge ignition, a single Bing 49 diaphragm type carburetor and rotary valve induction. When last built by Compact Radial Engines it was currently offered without a reduction drive, although when Zanzottera built it a 1.75:1 cog belt reduction drive was available. Starting is electric starter only and a
recoil starter is not an option.
