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.
