If you are referring to the "ears" on the cuirass (breast & back), then that was the first set of suits they built, and yes, inaccurate. These "ears" came from scans were apparently sent by the company who made the film suits. I was told, in an attempt to sabotage the ANOVOS suits.
The tooling we made was from studying about a thousand photos (I'm not kidding) of the full suit, and each part in full 360. Again, as I stated earlier, the originals are cast urethane, the ANOVOS kits are vacuumformed plastic. So details are unavoidably affected by this change.
In the ANOVOS kit we developed, the only parts we cast were the "gaskets and the "detonator" on the back. The original kit detonator was a disaster of about 6 vacuumformed parts that required a few hours of cutting, fitting, gluing seaming and painting. The slush cast parts were good to go out of the box.
Like my earlier note about Starship Trooper armor, the film armors, being cast rubber, were reportedly heavy, pron to tearing and hard to move in. A friend who was on the set told me the actors couldn't lift their legs high enough to walk up a normal flight of stairs and even running down ramps took some coordination. In studying the photos of the film suits, I saw two contributing factors; While the gaskets are ribbed, the ribs are solid. In order for a ribbed "Bellows" to function correctly, the ribs need to be hollow to allow for compression. We did this on the ANOVOS kits. The other issue, is the legs on the film suits are suspended in a less efficient manner. The design they used of a single strap suspension, allows the cuisse (thigh piece) to slide down, and rotate. When it rotates just a little, the back of the knee will get bound up. In combination with the solid gaskets, this limits the wearers leg movement significantly. We incorporated a "two strap" (really one strap but secured in two locations) suspension. This helps self center the cuisse and keep it from riding down. Something one of the ANOVOS owners vigorously fought with us about, until, the ANOVOS test guy wore the new suit and raved about how much more comfortable it was. It would be interesting to see if the kits they are "selling" now keep this change.
These changes are they type I was referring to in my earlier post. Changing something to improve the customers experience over the ill designed movie version.
