I think Goldberg airplanes are WAY too overlooked by most fliers.
I agree. I hope the Tower conglomerate buy-out won't or hasn't already killed them.
I have a Goldberg Hot Stik and it's a fantastic flier (NOT a trainer, though). I always liked the Falcon 56 and Sr. Falcon. From back when there were trainers and THEN you moved up to aileron trainers, then low wing trainers. Folks had more patience in the past.
