Want more trivia? The Antoinette engines all were in a 90-degree V configuration, were the first to use fuel injection, had aluminum crankcases and individual water-cooled cylinders. And hemispherical combustion chambers too! Engine tolerances were 0.01 mm, or 0.0004 inches. Wow. Wild West Showman Samuel Franklin Cody made the first powered flight in the UK with you guessed it, an Antoinette engine. Antoinette also made the first flight simulator, a rather crude device of a seat on a half barrel, curved side down, with “instructors” rocking the barrel.
Other records included altitude (155 m in 1909), speed (77.5 km/h in 1910), and first successful landing in a body of water (it didn’t sink), namely, the English Channel. Bleriot, who made the first successful channel crossing, was a former Antoinette vice president.
Personally, I’d love to have an old Antoinette or Hispano-Suiza V-8 engine from that era, or a Liberty engine, which came in configurations from four to 12 cylinders. No idea what I’d do with one, though… living room isn’t big enough.

Cruise speed is also nice at about 150 mph, not fast enough for cross-continent trips but enough to go north to south in a day, with a little luck. I would, of course, get mine IFR with the same avionics as in the RV-9A.

Getting back to reality, if I dare, the RV-9A with the Garmin G3X Touch avionics has given me amazing capabilities, especially for the E3 research. I made a much better decision than I knew when I bought it.
