That is a cool video. This is one of the early 90's NATS at Lawrenceville, IL. I'm thinking either '92 or '93? I think I was there that night. Lots of "notables" in there also. Bill Rich, I think, and I think that's Gary Hajek launching for Randy. I have it in my head that the engine was a one off bar stock engine randy built for the experiment, and not a ST.60??? It was not a true contra-rotating prop but the second prop acted as a stator to help with the air flow down the fuselage. it had a really neat sound when it spooled up at start and wound down on landing. Might do a search on the site as I think Randy has discussed this before, or maybe he'll see this and fill in the blanks. I remember the airplane having a really nice corner, probably the best I had seen to that point in time. I would love to see and hear it in the air again!
Type at you later,

PS to add that I see a real young Allen Brickhaus also.
