That is Yvonne DeFrancesco with Tony (if memory serves). I saw Tony fly his Troublemaker back in the late ‘70s. He was flying an EU1-A before he left the east coast to work for Circus Hobbies in Las Vegas.
Yes, the Aurora is a terrific airplane and I really liked the Arrow. The post ballistic era 60 sized designs (early turnaround) all flew very well, though they were not really any slower, just bigger or at least longer. I always wanted to build a stretched Brushfire for turnaround, maybe someday.
