Of interest, the article mentions that he once leased a Jet Commander, but before that, and more importantly to us, he owned a 560 Commander. There are three black and white photos of the 560, including one interior shot with Arnie sitting in the pilot's seat. The caption that accompanies the photos mis-identifies the 560 as "the hefty Rockwell Jet Commander"(!) What became of that 560? Regards, Stan N681SP ________________________________ Message 6 _____________________________________ Time: 06:36:23 PM PST US From: "Don" Subject: Re: Commander-List: GREAT SOUND Aren't all OR most round engines geared?

There were a very few 985s that had gearing. Not sure if they were certificated or not, but at least one 985 with gearing for the propellor was used in a racing version of the Beechcraft Model 17. A high percentage of the 1340s were geared. Many of them were used in the Boeing 247 and the Nordyn Norseman, but the 1340s in all the production Harvards and Texans were all direct drive though many have had geared versions installed. That nice little Russian engine is built both ways! As Always, It All Depends!

Was: Pressure Carburetor? That's very nice, Milt. Did you notice how far BTDC the ignition fires? I was looking for valve overlap but the footage cuts at the precise moment that it should happen. Although there is one frame where the inlet valve starts to open while the exhaust valve is completely closed, indicating that his particular engine doesn't have valve overlap. That technique to increase power without any penalty somewhere else, has been developed in the late 60's or so and then only in very exclusive high-performance engines. My guess is that this engine is of a pre-1960's design; it is probably an aircraft engine.
