Delta Dance
William C. "Bill" Doran ([email protected]) submitted this photo of Next Dance, one of seven Deltas piloted by Southern Air R/C Club member Jarred Esau. Bill scratch-built the Delta wings over several years.
Bill wrote: "Next Dance is the sequel to 10 Cents A Dance, which was lost because of an electronic failure in 2012. Next Dance was at first powered by an O.S. .77‑converted ducted‑fan engine in 2012 and it reached a radar‑clocked speed of 163 mph.
An O.S. .91‑converted ducted‑fan engine replaced the O.S. .77 this year and the new speed has not been instrument‑checked so far. We guess that it has to be quite a bit faster with the more powerful O.S. .91 engine. The prop being used is a 10 x 10."
