Are any other helicopters the subject of a SFAR like the robbie? Do any other helicopters have such fatal vices (even when inside the flight envelope)? Are any other helicopters having unexplained breakups in mid-air?
I understand the appeal of a cheap trainer (not what it was designed for) but letting low-time pilots (post PPLH) out in this thing is inviting problems. How much flight at Vne or close to it is actually covered in the PPLH syllabus - is it one of those things that is just talked about all the way to CFI level as part of the SFAR 73 awareness training or is it physically taught?
