A friend invited me to his radio-controlled ("RC") airplane club's monthly race. The club members race their bright red, battery-powered, "Pitts" model biplanes. These RC model airplanes are made of foam (3.2 ounces), have a 17-inch wingspan, and are about 15 inches long. They have to complete 5 laps around a 2-pylon course, about 40-yards in length from pylon to pylon. It is a blast to watch them fly, and sometimes crash!
I have a whole new appreciation for BIF! I had a D750 with a Nikkor 24-70mm 2.8 VR lens (woefully inadequate reach, I know) and it was tough to zoom in on them, let alone track them through the air (at speeds of 30-35 miles per hour), and get them in focus. I was in Shutter priority mode at 1/1000 ss, continuous shooting (6.5 fps) and continuous focus but very, very few of the approx. 500 shots ended up in focus! I was mostly panning which of course blurred the backgrounds on low-flying shots, which I'm not sure I like.
Anyway, it was a ton of fun, great clouds after a rainy morning, and I thought you might enjoy some of precious few that turned out in focus. CC requested! Thanks.
