I have enough Robinson time to not be a super fan of the helicopter. I will note that the company has not fixed the mast bumping issue, they have simply changed the basic training to routine to better teach students how to avoid it. While I agree with your earlier note that the teetering cyclic is easy enough to learn, it isn’t very comfortable for an instructor. For example, a short pilot has the stick pulled way down and the instructor has to have his hand up around his chest to be within safe “oh crap” reach. I get that Robinson’s are very popular world wide for many uses, but never as a military training helicopter - I think the primary reason is the extremely low weight (the same thing that makes them less expensive) is not a positive thing for military students.What's the right aircraft? Bell no longer supports the 206 and a 407 GXi costs around $5 Million.
My recommendations (as if anyone cared🤣), in order, would be the Enstrom 480B, MD 530F, the Leonardo AW09, or the TH-73.
