It's not the syllabus that needs changing - it is the aircraft being used for training that needs replacing... Remember that Frank R. never designed this aircraft to be a "trainer".
Low inertia blades and skinny skids just make margins that much thinner.
At least it was only a 22 and not a helicopter
I appreciate the sarcasm in that but IMHO the R22 should be in the same class as a Rotorway, never mind what the FAA says (it's a well known export item for the US).
