It is hard to enough to get parts and engineers to look after machines still in production let alone a Hiller !

Probably the best Hiller engineer in the country, Roy H died a couple of years ago and those who worked Hillers in the crop spraying days are all into their 60's plus now.
Simpler times a lot less legislation. The 47's seem to be enjoying a resurgence. There are a couple of Hillers in the U.K awaiting a rebuild. Finding the time is the problem.
It would be nice to see a flying 12E over here again.
