If R-22 production ends for some reason then I think Enstrom might return to trainer production with a lower cost non-turbo version. Just my guess.
Schweizer (now owned by Sikorsky) is likely to just increase in cost under the management of the giant company. Just my opinion.
Both are three seaters and therefor not ideal as trainers but they have a better fatal accident history than the R-22 according to NTSB records I have seen. Again just my opinion.
A new company is needed for a fresh start without crash lawsuits.
