Vanguard Helicopters flight school, train on the Enstrom, but we do also have a UH12C.
We are in the UK, at Henstridge on the Somerset/Dorset borders.
You would need to get an FAA ppl to fly the Hiller, as all European based Hillers are on the N reg. But you can do that in the UK,
and does not present a problem.
Call us at the above telephone number, or call in and see us and have a chat.
