I had an idea they were fixed at the beginning, not sure.
On matters Robinson;
I note in the latest 'Robinson News' an article honouring the late Barbara Robinson. I think she was a marketing genius and although I never knew her she was always mentioned in high regard to me by those who did. Please add my sympathies.
I also see that there is an article honouring Simon Spencer-Bower, an instructor of high experience from New Zealand. in fact they mention that he may evn be the highest R22 driver around. remarkable!!
I know of at least one gentleman who had logged 18,000 hours by 2003, every one of 'em in R22's (mustering, or going there to muster) and since then has been probably not been doing much less than 6-900 hours per year.
Of particular interest is that I do not think that he has had a single emergency requiring immediate landing.
Yep terrible aircraft these robbo turnouts eh?
