No need to make more. They are still modernizing and reselling existing ones.
While a refurbished Huey would be good, I’m thinking more along the lines of a consumer Huey. Though it’s easy to compare it to a passenger minivan, probably a better comparison would be to a panel van.
A utility helicopter to transfer van sized cargo over terrain faster than it could be done on the ground. Say, in mountainous, swampy, or rocky terrain with few roads.
The design emphasis would be on a more efficient engine and lower maintenance. Maybe even adding fanwing props (centrifugal fans) in pods for much better lift and stabilization.
