In this case I was mistaken, thought it was a Ringmaster and Dan McEntee is correct, builder and pilot is Dan Banjock. (Older I get, seems the less brain cells I retain.

) Couldn't find the particular video Ken pointed out (that I video captured), but found another one that is similar, posted only two weeks ago.
It is a short video, 3 minutes 42 seconds long. In the other video I just mentioned, with a closer view of the pit crew powering it up, aircraft appears to be based on a Sig Skyray with an A-10 like profile fuselage and tricycle landing gear. Pulse jet is mounted to the bottom of the fuselage with a portion of the lower fuselage cut away for ground clearance. It has a single rudder conventionally mounted.
With this type of arrangement, it would be possible to come up with a Ringmaster variant done is similar fashion. (Or, Flitestreak, may be even an SU-25 Frogfoot, etc.)
