Don built three Fury's
Fury 1 mimicked the color scheme in the Profile Publications book on the FJ Fury. Had a built in tank - and tank trouble. This one was quickly replaced by...
Fury 2 had a different fin/rudder, 2 fences on each wing and a different fuselage stripe. Tank was removable this time. This one got 39 points (out of 40) at the 1966 NATs. Also was published in Flying Models, looking for the issue, thinking it was late 1966 or early 1967.
Fury's 1 & 2 were candy blue with red & white trim. The candy was many coats of blue over a serious metal flake silver, looked spectacular in the sun. Both powered by Fox 35. Fury 2 also used a "Spin-a-Flow" Muffler
Fury 3 switched to a muffled McCoy 40. White with green & black trim. The lightest and most powerful of the 3 Fury's, naturally it flew the best too. Later refinished in light blue (misplaced the picture).
While not a Fury. Don's Ultrasonic was at its core a Fury with a couple inches more wing span. A slightly more raked Fury 3 fin, the tall canopy was replaced by a long low one. One of my favorite things about this one was the way the paint stripes on the wing and tail connected with the fuselage stripe. Very skinny rear fuse, about 1/2" wide at the elevator hinge line. Don flew this at the 1968 & 1969 NATs
