I built the first Laser Chasers about ’61 or ’62. Over the next few years I cleaned up the design a bit (smoother lines and an auto-rudder) and eventually published it in Flying Models in 1970. I used the TD .049/.051 combo on a Taibi tank mount faired into the cowling. Added a disc to a “pinch-off” Tatone timer for the auto-rudder.
I also built a slightly smaller version with the same engines stuck to a fiberglas boom fuse to decrease frontal area. This version showed real promise but I had to put it aside when I started grad school. Now I would use one of Galbraith’s bad boy Cyclons, a folding prop, and lots of CF to take the loads.
Maybe someday…
