The thing is, Lu's report in engineering terms proves or at least puts a very strong case forward for the non-certification of R22's/44's.
Joe on the other hand has a valid point in that he has flown the machine and is still alive to tell the tale.
As an independant and unbigoted witness I will always take the the side of someone who looks at the past AND the future and can consolidate a reasonable point of view from both as opposed to all of the Robbie ex-trainees I spoke to who merely reiterated their instructors retoric.
For info, one of the guys I spoke to, now a twin turbine IFR Captain who learned on the Robbie, said that he, "was demonstrated and taught low G, out of trim and sideslip manouevers" as part of his basic training.
If this doesn't count as disreputable behaviour (ie. conradicting the flight manual) I don't know what does.
