Hello Bob!
Thanks a lot for your comments and for the photos!
The first one - is a twin engine variant of the Seasprite (the early ones only had one engine - I read that they seriously needed more power). As written on the fuselage it's from a HSL squadron - that would be a light anti-submarine squadron. Now the HC-7 was a support squadron and some its detachments only did search and rescue work. I would be interested in building a one-engine search and rescue helo.
BUT there is one story about Navy "renting" one of their MAD (Magnetic Anomaly Detector) equiped helos to look for a weapons cache in the jungle (lots of steel, eh?). Maybe you just photographed this very helo?
The second photo is a H-3 Sea King. Those were also used by the HC-7 for SAR work - one of these days I'd love to build one, too, but now I would like to concentrate on the Seasprite.
Thanks again and have a nice day
