M197 Cobra Gatling gun

Sharing my deep fascination with helicopter weaponry, especially the Cobra's M197 Gatling Gun. To me, this gun has the greatest potential to come alive as a scale model, primarily due to its rotating barrels. I have designed and built many versions and sizes of this gun for different customers over the years, for 1/6 Len Mount and Alterbaum, 1/7 Vario and 1/9 Roban, static and animated. The latest version is a fully auto-run, multimedia experience featuring motion, sound and smoke. Here are all the different gun and TSU variations.
Edited: I've just added the final completed version of the gun and TSU.
