Is the 66 now approved for G- registration?
I would not be so sure that there is no market for leaseback. True tat until recently a PPL wanting turbin etime / hire would most likely end up with a 206 or MD500. That's what it was like when I decided that I could get more hire time with a 120 - there were no 120's in the south of England, no competition but no market. It took a couple of years to build a base, and even over winter I have been getting 20 hrs / month average.
A lot of my hires are public transport work and I suspect the R66 is a less attractive option - to rich punters the look of arriving in a 120, 206, 350 is way above a Robinson.
I do think there could be a "big" market for PPLs who have trained 22/44 - less of a shock to go 66 than another route.
Worth doing the homework before writing-off the rental angle, including checking the insurance restrictions (if hayward want 150hrs / 100 turbine / 50 on type before allowing someon to rent the machine bang goes your PPL hire market!
