Personality:
Appearance:
Mobile Weapon: Sachmis (pronounced ‘sek-met’).
Weapons:

Sachmis was originally designed as a testbed for a number of revolutionary technologies that would later be incorporated into next generation MBTs, AMP harnesses and battle suits:

General design

Sachmis’ designers first experimented with the concept of the bipedial walker, initially planning for Sachmis to be a digitgrade, reverse-jointed walker complete with an armored canopy, fully and a conventional cockpit. Further physical trials and simulations found this design to be inherently flawed, with its established height, high center of gravity and inability to mount heavy weaponry counterproductive to the general battlefield Sachmis was expected to satisfy. Looking to real-life examples found in nature, it was instead decided that Sachmis would be a quadruped platform, with its overall shape fashioned in the likeness of a lioness.

CNTs—or carbon nanotubes as they are typically known as—were used extensively to reinforce the internal and external components of Sachmis’ body, while an advanced composite armor sleeve protects the machine from damage. The composite material consists of spaced-armor sections shaped from boron carbide plates, titanium alloy layering and aerogel textiles, with the outerskin wrapped in a hexagonal blanket of ablative coating supplemented by a lower skin of superconductive and refractory aluminum-like metals.

Sachmis’ pilot, Maxwell O’Niel, is stationed deep within the machie’s center, and is surrounded by a cacoon filled with a gel-like substance similar in function but stronger in composition to D30, a ‘liquid armor’ material that hardens upon being subjected to suitable amounts of pressure.

Sachmis’ is controlled through a series of neurological interfacing technologies, which allows Maxwell to literally become his machine, feeling its every motion and each blow upon its body. The entire machine is powered by a fusion reactor, while its movements are made possible by servomotors and synthetic carbon-based muscle fibers that also afford considerable running speeds and jumping capability.

Weaponry

Sachmis, unlike other types of mechanized walkers, was not designed with hardpoints (or ‘weapons stations’ as they are officially christened) in mind, limiting the vehicle’s overall modularity and capacity to efficiently acquire (and engage) targets whilst on the move. Instead, Sachmis’ main weapons have been buried deep within her hull, allowing the vehicle to sport a smaller profile while granting the systems the protective benefits of Sachmis’ armor.

Two (2) MTX-98 Autocannons: The MTX-98 is a revolver-based autocannon that—rather than using conventional solid propellants to launch its projectiles—instead uses a plasma cartridge to ignite a set amount of space-confined fuel to propel a solid projectile. As the pressure seals employed in the gun’s creation need to be sufficiently tight and strong to prevent accidental leakage (and with ample homage paid to the very nature of ETC weaponry), the MTX-98 outperforms traditional cannons, though at the expense of the barrel’s operational life and the need for a constant source of actual liquid propellant.

The rounds fired by the MTX-98 are a throw-back to the early days of the gyrojet, a 1960s-era technology that stressed the battlefield significance of rocket-propelled bullets similar in size to .45 ACP rounds, with the 57mm rounds of the MTX-98 capable of maintaining their trajectories and velocities without being effected by drag or air resistance for a considerable distance using petite rocket motors built directly within the rounds themselves. Additionally, other ammunition types—such as sabot-discarding ammunition, armor piercing high explosive ammunition and canister shot— are made use of.

Particle accelerator: Mounted along Sachmis’ spine is a particle accelerator that uses powerful electromagnetic fields (which allows for plasma acceleration to be used) to fire a stream of neutralized particles at a target. Like other beam weapons, Sachmis’ weapon is negatively affected by environmental factors such as dust storms or artificial defenses like IR smoke or dust casters. Altering the power of the beam, Sachmis’ particle accelerator can induce an EMP-like effect when hitting a target.

Additional defenses

Electromagnetic field: Self explanatory. Reduces the speed of incoming shells, but does not stop them. When increased to shell-stopping levels, the field can kill nearby organic creatures that are unshielded from its harmful effects.

Height: 2.6 meters (can retract to lower heights on account of ability to crouch)
Weight: 45 tons

Three things:
First, Increase the height, that's about a man's height plus a bit. Comparatively, if it weighted that much in such a small area it'd fall through the metal most of the time rather than being mobile.

Second, make a better physical description or find some sort of suitable picture.

Thirdly, even with all that stuff in, no defense is perfect against everything.

Other than that looking good.

1) Modern MBTs are around that height. In fact, the M1 Abrams is about 8 feet tall (http://en.wikipedia.org/wiki/M1_Abrams), which is about a foot less than what Sachmis is currently stated to be at. Older vehicles, such as the M4 Sherman,(http://en.wikipedia.org/wiki/M4_Sherman), pushed 9 feet. Additionally, the pilot of Sachmis is actually lying down in the machine, his posture mimicking that of a light cycle rider's:



When it comes to weigh distribution, four legs technically beat out two, as the pressure can be expressed across four surfaces rather than a simple duo. This means less pressure focused in one area. If it's too much, I can widen Sachmis' paws, which would make sense given the terrain she and her controller will be navigating through, with the paw-widening further decreasing her weight's impact on the surface (by increasing the paw's surface area) that she is walking upon. In all technical sense, this isn't even needed.

For a frame of reference, the M1 Abrams actually exerts less pressure on the ground than a civilian car, like a Ford Focus or even an H1 Hummer. This is a 60-70 ton MBT mind you.

Four-legged creations, by default, are going to be shorter than two-legged ones. It's why you don't see tigers that are six feet tall, yet they weigh hundreds of pounds.

And for the record, having a 50 foot machine that only weighs 60 tons makes little sense. The internal structure of that mech alone is going to be rather hefty; add on the armor and the weapons, and the weight increases. You may want to checked out this wikipedia article on the square-cube law: http://en.wikipedia.org/wiki/Square-cube_law, since it will explain in detail what I'm getting at.

In terms of the defenses, I know the limits and capabilities of what I put into my sheet. I wouldn't do that if I didn't know what this stuff does.

Not exactly only for show, but to put all the pertinent information right out there so it's a bit easier to get yardsticks for various statistics about a mech. I highly doubt the exact amount of wattage August's mech will ever be a fact you need to know, but I added it in the character sheet anyways to help establish various (but vague) lines of can/can't do. I just pulled the numbers out of thin air, but I wanted a number that was higher than modern-day fission reactions to show that it was high-tech and high quality. It's just stuff like that; you don't need to worry about making sure that all of your subsystems'll be optimally placed or any crap like that, it's just to help flesh out the capabilities of your mech; I suppose an offhanded way to put it would be flavor text++.

Yeah, mostly this.

However, I had no idea people were trying to pull machines that tall into the RP. I just went with a basic height of a modern tank since that's what the mechs are supposed to be, I guess? Equivalents of tanks?

The lightweight can be explained by the fact that it's set in the far future, tech's gonna be improved and lightweight enough to support such things while not losing out on integrity. The height is because you'll have arm-sized stubby legs either directly underneath or splayed out to the sides, making it improbable to support it's own weight anyway.

...if it's made out of lightweight material, why is weight an issue?

The bolded point sort of contradicts your paragraph's first statement/argument.

The idea I've always had in my head was that mechs and mecha were to fill in a niche that couldn't be filled by wheeled/treaded vehicles at all; something with the firepower (at least) of an MBT, but with the mobility and maneuverability of, well, something with legs.
I've been talking with Tentacle and he hashed out that that's why mechs, weapons systems that are a good deal more expensive and fiddly than (relatively) simple tanks, have become the premier fighting vehicle in the Junkyard; although tanks, APCs, IFVs, and other conventional vehicles are still used, mechs rose to the forefront due to their utility in getting around the Junkyard. They have the ability to get through places that, before the advent of mecha, were limited to infantry (which seems to be what ninety percent of the Junkyard consists of; assorted wreckage so thick it'd be a guerilla fighter's wet dream), while still being able to bring to bear the devastating power of a conventional tank.

Because your vehicle weighs eighty tonnes, thus contradicting the use of your claim of lightweight materials, and your subsequent use of an MBT as an example. Things that are splayed out to the side don't work, with spiders being a premiere example. They can't get bigger than they already are, due to, as you already mentioned, the square-cube law.

Splayed out legs do not work, simply due to how weight gets distributed. Like, something the size of a man would be acceptable, but nothing larger than that.

you contradict your own point. your mech weighs 80 tonnes. That is nearly twice the weight of any other mech created so far. Piles of junk are unstable and assuming each of your feet are a square meter (which would be quite large), each foot is putting the weight of 7 full size H2s(to use your Hummer example) on a space smaller than a kitchen table. You would be buried in junk before you could even take a second step.

Most of that weight comes from the mech's internal machinery, however I could reduce its weight to 45 tons to make it more plausible and more in line with my overall description. Even still, it shouldn't matter given how the machine in general doesn't exert more pressure on the ground than, say, some of the other mechs in the RP (especially when you factor in their dimensions and sheer scale). Physics isn't really in your favor with something that tall, even if you're using ultra-light materials.

Keeping in line with overall theme RP, I suggest we get away from the whole 'science thing', like I initially stated a page back. This is a mech RP, after all.

Also, the legs aren't splayed out. Sachism looks like this if anything:



I think you're describing a hexapod mech, which is an entirely different shape (though, mechs of this design would probably be uncontested when it came to moving about the Junkyward).

Reducing it to forty-five tons works nicely. That wraps up about everything. Accepted.

And now for a change of pace:

Name: Ian hart

Age: 28

Gender: Male

Looks:
Shoulder length black hair, light blue eyes. Wears black coveralls and black boots with bright green laces. He carries a Falchion outside of his aircraft.

Mobile Weapon:

CK157 Blasthammer
Crew: 1 or 2
Mass: 12 tons
Powerplant: 9600kWh Capacitor bank (3 hour flight time)
The CK157 Blasthammer was conceived as a fast response strike craft for hitting targets that would take far too long for conventional mechanised forces to reach. While lightly armoured, it is nimble enough to survive combat and packs enough of a punch to knock out a medium sized mech.

Weapons:
12.7mm gatling gun - for 'soft' targets
2 x 23mm autocannons - for slightly less soft targets
2 x 16 x 57mm rocket pods - for pains in the rear
2 x 240mm 'Nova' Wire Guided rockets - pre charged capacitors power beam emitters that trigger at close range.

Personality: Ian is selfish and greedy but cares far too much about what others think of him. He chooses his actions to benefit himself before others and carefully tailors other peoples impressions of him.

Short Biography: Once a part of a larger force, Ian decided that he would make more of a profit on his own. Not content to leave with just his earnings to that point, he stole an attack aircraft and was never seen in the area again. Knowing better than to operate in his old area, he headed for the centre of the Junkyard.

He flies out of a cave system that acts as his base of operations, housing rearming facilities, a reactor for charging his aircraft and spare battery packs.

I took the weight of the mech and divided it by 4, the number of legs. Divide the weight by the area of each foot to give the ground pressure. I divided that number by the weight of an H2 to have something to compare it to.

Truth be told, the weight of your mech still bothers me. 45 tons of titanium (ignoring the aerogel for now) made into a solid block would take up more space than your mech does. Adding it the aerogel makes the size of your mech physically impossible regarding the weight. It's like trying to fit a gallon of water into a quart sized bottle.

You obviously can't read, bro.

What part of 'composite' don't you understand? I mean, really, do you even know how much Aerogels even weigh? Anything about their density? Anything at all?

I mean, let's be honest: I could rag on the implausibility of your 12 ton Super-Apache and its power plant (which amounts to nothing more than 3 capacitors of unknown type that only provide 3 hours of flight time, which is laughable considering the nature and the intended role of your aircraft). Is this 12 tons unloaded or loaded?

I think you're nitpicking for 0 reason.

That, or you're asshurt over something.

So which is it?

Also, try reading over the other sheets, if you will.

EDIT: If it's the overall height to size ratio, take a gander at modern MBTs and other AFVs.

Aerographene weighs in at about 160 grams per cubic meter. This is pretty damn light, weighing even less than its volume in air. Assuming the aerogel is conservatively just 10% of your volume, that would put your overall density at just over 4000kg per cubic meter. 45 tons at this density would take up 10 cubic meters, this is just under the volume of an average sized elephant which, strangely enough, is about the height of your mech. Take out space for the pilot and the other lighter objects like computer systems and it is absolutely impossible for that abount of material to fit in that small of a space.

Less of an Apache, and more of a super Hind. Now a fully loaded Hind weighs in at about the same weight as my helicopter and as far as firepower goes can carry three times as much firepower as an apache as well as a squad of infantry and is also faster.

Addressing the flight endurance, an Apache only has a flight endurance of three hours.

This would be the maximum takeoff weight of course. As a dedicated attack helicopter I can do away with the troop transport capabilities and add more weapons. Honestly, I probably lowballed the weapons capacity but i decided to err on the side of not being seen as overpowered.

An Abrams is 10 meters long. add in some height to account for that the mechs are standing on legs and it about matches the height of the other mechs abeit that a tank has more space inside of the crew.
