König SC 430

Compact Radial Engines SC 430

 

The König SC 430 is a three-cylinder, two-stroke, single ignition radial aircraft engine designed for powered paragliders and single place ultralight trikes. The SC 430 is a unique three cylinder radial engine that is very compact and light weight at only 17 kg (37 lb). The engine features single capacitor discharge ignition, a single Bing 49 diaphragm type carburetor and rotary valve induction. 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.

Earlier versions produced 24 hp (18 kW) at 4200 rpm with a slide-type carburetor and reduction drive. The later version is rated at 20 hp (15 kW) at 4200 rpm. Time between overhaul is rated as 300 hours.

The SC 430 shares the same bore and stroke as the larger four cylinder König SD 570 radial engine.

The engine was originally designed and produced by Dieter König of Berlin, Germany. The design was sold to Zanzottera Technologies of Italy and then sold again, along with the rest of Zanzottera's two-stroke ultralight aircraft engine line to Compact Radial Engines of Surrey, British Columbia, Canada.

Unit cost from Compact Radial Engines in 2001 was US$3600
