Right here the very first thing I wrote:
Spoke of a modified EVA - even then made no mention, or even any intention, of baseing this assestment on the inner workings of the design. In short if you want a mecha to perform like a human, be able to navigate a wide variety of terrain, jump, climb, pick itself up unassisted from a fall, carry a variety of weapons ... well its going to have to be basied on a humans joint, mobility and weight bias structure...
Votoms, Labors and Heavy Gear fail because the legs shift weight bias tword the feet...and togther with Gasaraki, they all overlook the drastic importance of our backbone and flexable shoulders...EVA takes most all of that into consideration, and thus if you scaled them way, WAY down and took off those fin things on thier shoulders you end up with a very plauseable design able to mimic most human motion and flexability.
And if the human basied mecha can't run through an obstical course like soldiers do...includeing crawling around on its hands and knees, climbing rock walls, balanceing on beams, and picking itself up from a fall...then the mecha is far to specialized to be of much good especialy in combat
...
it was a guy in a suit, held up with wires and support beam out the back...it was not real, wasn't even made of metal...and the design, speaking for itself, has lots of problems - number one is that it could not lift the cargo containers without some form of counter balance to offset the additional wieght placed on the design...additionaly it doesn't have the physical mobility in the legs to carry such loads...
I did read it. Even at the height you give, it's still incredibly far-fetched. Much more so than most mechanical robots. In the real world, people who suffer from gigantism are incredibly frail. The Evas, especially with their thin proportions, are just going to be that much more so, even at only 20' tall.
