Interesting that some of the drawings revert to a lower profile radome not much bigger that those fitted to the prototypes and initial production examples.  I suspect that Lockheed could package the radar in a significantly smaller volume than was required in the mid-1950's but that the Hercules' nose profile has become a trademark that's left unchanged for commercial reasons.
Also, does anyone know what a tiperon is?

Considering the picture this term appeared in, I would guess it's a combination "tip" and "aileron" and thus refers to the extensions at the wingtips...

That sounds right. The tiperon appears in only one picture, so maybe it wasn't that effective or worth the expense to test it out. Interesting concept though! Some other pictures mention an increased chord/span aileron, that's probably the easiest/cheapest way of increasing slow speed roll authority.

As a side note, the tiperon reminds me of something seen on the Martin Kitten III of 1918-1919. I attached a picture from the aerofiles website. NOtice partially retractable landing gear. The only Kitten remaining is hanging from the ceiling in one of the Garber hangars.

I found this illustration of a C-130 gyrodyne some years ago.  I don't know a thing about it.

I think it's a Groen Gyrolifter thing (as in Groen bros. gyroplane)

Can you imagine the engine needed to lift the C-130 and how much Cargo area the Engine and gear box would use up?

Amazing to think about. I like the idea.

The main rotor is unpowered (this being a gyroplane), so there would be no engine and no gearbox. I can't remember if it's supposed to have tipjets of prespin the rotor for a jumpstart.

The concept is the re-incarnation of the Fairey Rotodyne (and that's told by Groen
Brothers Aviation, too) and it uses tipjets, as is mentioned on the companies website,
too (http://www.groenbros.com/).

Oh I see it like an Auto Gyro, with rockets or jet engines on the rotor tips.

Out of the Box thinking.

Is the real world ready for it yet?

It is part of the renaissance of Blimps / Zeppelins and other aeronautical ideas.

The Stretch STOL Article can be found in the issue of Air International October 1977 pg 209,210.
