I know there's many views centred on the (un) airworthiness of the Robbo product, but having attended their safety course in 2016, I think it is a great forum for building awareness.
As suggested, it does spend a fair bit of time showing the fatal consequences of operating outside the approved limits, and helps with an understanding of the obvious deficiencies in the rotor system, along with strategies to manage those shortcomings (my words, not theirs).
For me it was money extremely well spent. I wonder whether insurers should begin to insist that PPLs insuring Robinson machines must have attended the safety course, or face challenging premiums?
Sounds eminently sensible. Neither of the incidents under discussion here was related to a flaw with the aircraft (and could have happened on any type). Both episodes stemmed from woeful ignorance in the seat-stick interface which a safety course might improve.
