Very interesting mod, thanks for your replies.
I guess the only downside is the 212s are getting to be pretty old airframes by now.
Not UH-1 old but still long in the tooth.
Good to see Canada has had the balls not to allow ex-military helicopters to be operated on commercial work, which makes conversions like this economical.
The Bell 210 is a great idea but probably out of alot of operators price range.
