At close to 2500 aircraft produced since its first flight in 1954, this model (which the US Army designated as “H-34” and nicknamed “Choctaw”) is second only to the UH-60 “Black Hawk” model as Sikorsky’s most-produced (@4000) and ranks about 15th in overall world production. Designed as an anti-submarine platform, the military used the H-34 until the early 1970s, yet to this day the model still sees some civilian uses. On a visit to Chicago in the 1960’s, my parents indulged me in a ride in this helicopter as operated by Chicago Helicopter Airways.
Like the S-55 model (for which I also have a MOC posted on these boards), the S-58 front end has a distinctive pilot cabin sitting above and behind the engine compartment “nose” which is covered by a bulbous gull-wing cover. Two Lego pieces (#45406 windscreen cab with hinge and #30083 windscreen canopy half-sphere) positioned together enabled me to envision the front end of this helicopter. As shown in a rendering, in my MOC the half-sphere swings up to reveal the engine. Just like the real thing, in my MOC a part of the tail is hinged to swing forward for efficient storage when shipping it. About a year ago I sold a couple of this MOC on eBay as kits. The model has 195 Lego elements.
