It's sad to see Enstrom closing its doors for good. I'm a geologist and in 1982 we used a 280C (from Les Hélicoptères Verreault, now defunct, I believe) for geological survey work between Baker Lake and Chantrey Inlet on the northern Canadian mainland. It worked fine and as I remember was well-liked by the pilots. As to the Robinson, one pilot I knew from another year recounted how he'd been invited to test fly a Robinson (model?), did so, and was so frightened swore he would never set foot in one again. Different strokes for different folks, I guess.
