New World Record RC Airplane Speed 548mph

Strong Santa Ana conditions on Jan 19 2021 provided enough wind for Spencer Lisenby to bring the dynamic soaring speed record back to its birthplace of Parker Mountain, CA. Wind gusted to 65mph and temps were 45-50F. This flight beat the previous record set in 2018 at Bird Spring Pass by only 3mph. Filmed with a Gopro on my head while flying. Best viewed on a large screen with high resolution. Max acceleration estimated around 90-100G.
