Surf used the same system in the AS 350 for many years. I think ELP ended up on the Sunshine coast & was sold to West Australia or was it Tassie. The 350 had a winch but this strop system was much quicker, easier & took 2 people unlike the winch. I can't recall any accidents with it.
Spent a lot of time in UHC when it was rigged up for bush work!
