Alan Mann and Fast Helicopters both have Bell 47s.
AM's own machine is a G5A but that's offline and won't be available until some time later this year but they have access to a customer's machine, a G5.
Fast will have a B47 available at Shoreham in a few weeks. I don't know which model it is.
Check prices - Fast will probably be cheaper than AM.
Worth a try?
Definitely.
The Bell 47 is a wonderful helicopter.
If I had my time over and money was no object, I'd do my training in a B47.
