This video is from the late 80's/early 90's back when glow ducted fan was at its peak and the only practical means of propelling an RC jet around the sky.  The flight was at a US Scale Master's competition as you can tell from the Figure 8 flown early in the flight which is a required maneuver in the competition.  The airplane is a Mark Frankel designed F4D Skyray powered by a Dynamax glow ducted fan.  It was a hot day as you can tell from the takeoff, but I'd say for a 24 lb DF model, not bad!  Anyone who's flown glow ducted fan can relate!  Also, the dreaded dead stick landing...which in this case happened in a good spot for the pilot.
