As my handle implies I did my ab initio training on the Grob G109b Vigilant with the VGS.
I know some people think it was the wrong aircraft for the job but I am confident when I say learning in a taildragger with a 57’ wingspan and no glass cockpit meant it was easy to fly but hard to master.
Adverse yaw meant you needed plenty of rudder co ordination, good lookout was drilled in naturally and it had real but safe stall characteristics such as clean breakaway and wing drop.
i found any other type easy afterwards and agree a trainer should be just that with enough bite to keep you on your toes.
