And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Welded a lot of parts on those Allisons, my wife welded and brazed the fuel manifolds, they called them The Beasts, something like 65 braze, and 12 orbital weld joints, all joints got a 6 view radiographic inspection, Allison has about the tightest weld specs in aerospace, in fact where I worked they tested welders and brazers to Allison specifications, which qualified you to near all the other engine manufacturers metal joining spec's, we made components for. RocketAreoDyne and PrattFlorida, and the rocket division of Lockheed, had pretty tight spec's, they where zero defect requirements because the parts where for rocket engines. Best job I ever had, awesome work, it was the company that invented the mandrel bending system, we most made "ridged tube assemblies" for everyone.
There’s a mod that drops that little thing into a Cessna 206, if memory serves. Sounds funny when it starts…you expect to hear the rattling nightmare that is a Continental but instead you get whirrrr…tickticktickwhoosh…
In the OH-6, two guys could disconnect the engine, lower it with a pulley system and carry the engine (it only weighed about 150lbs) out of the way and put in a new engine in about 3 hours. Easier to sling it back to the shop but easy enough in the field with good conditions. It was far superior to the Bell OH-58 in my opinion.
Aerospatiale TwinStar, I think. The engines are Allison (now Rolls-Royce) 250s which were first used in the Bell 206 and Hughes 300.

Proven platforms.
