Hi Green
Your picc prompted me to do some further research. It seems that Tinker Toy was flown with a T-tail, with a cruciform tailplane and (finallty?) with low-set tail plane.
N5DT was purely for R&D work and used to test the GM (Chevrolet) Monza car engine. She was grounded in 1978 after an accident.
Next challenge will be up in a few moments.
