An Idea

An 18-cylinder double-row radial engine with 700 ccm

We have been flying our 9-cylinder radial engine with 350 ccm in our Boeing Stearman PT17 since 2007. The engine is completely matured and runs very reliably in harsh everyday use.

Mario Seidel from Seidel Props finally encouraged us to approach the project “18 cylinder double-row radial engine” with 700 ccm – on the basis of our 9-cylinder radial engine. He had the idea of a four-bladed variable pitch propeller, for which he needed an engine with transmission. No test object is more suitable than our 18-cylinder double-row radial engine.
