Pius Job, a Swiss engineer, worked for Esec USA when he fabricated this engine from aircraft grade aluminum and steel in 1993. The lightweight aluminum cylinders are lined with cast iron sleeves to support ringed pistons, and the crankshaft and cam ring ride in ball bearings. It burns methanol (with oil mixed in for lubrication) on glow ignition and turns a 24-10 propeller at 6,000 rpm. The external rocker arms require manual lubrication before operating the engine. The engine is 10”-long, 9”-wide, and 15”-high (on stand).
