Generally, it is optimal to make a paper airplane symmetrical. I am not sure I understand what you mean by type of symmetry. However, some paper airplanes can be designed to be asymmetric and remain straight flying.

The answer to this question is a matter of some fairly simple physics which I will try to explain to you.

First, you need to understand that most paper airplanes are not really airplanes. Airplanes fly because the shape of the wing produces lift; paper airplanes mostly fly as projectiles, meaning that they fly because you throw them.

The first reason that the lighter airplane might not fly as far is in the design. Typically, the lighter paper airplane will have larger wings, and therefore, more drag. Since it is virtually impossible to make the paper airplane perfectly symmetrical, one of the wings has more drag which causes the airplane to spin and crash short of its maximum possible distance.

The second reason is also related to the design. If you have a light airplane with more drag and a heavy airplane with less drag, the heavy airplane can fly much more easily. This is because the heavier airplane has less drag as well as more momentum to "push" through the air. On this note, a piece of paper crumpled into a ball will fly further than most paper airplanes I have seen just because is has lots of mass for the level of drag it induces. The crumpled piece of paper also will probably fly much straighter that the paper airplane too, just because it is fairly uniform in shape. At this point, we are completely ignoring lift; but at such a small scale with such light material, it works better that way due to the reasons above. Of course, if you put engines and control surfaces on the paper structure, you change the game entirely. Now it has to fly with lift instead of as a projectile otherwise it will crash because it has no control. This explains why real airplanes are not just big balls of metal.

The weight of the paper. If you accumulate a lot of paper at one place (depending on the design) it could bring the airplane down faster than if you didn't accumulate so much paper in one place.

An airplane flies in a state of balance of many forces that act upon it, mainly its flying surfaces. Due to such factors as weight distribution on board, wind direction and velocity, spin of propellers, if any, etc. the plane can tend to fly off course unless the pilot makes an input to the air control surfaces to counteract these forces which are usually very mild. So instead of the pilot having to constantly correct for a constant force trying to set the plane off course, like a mild wind coming from the side, the pilot manually corrects for the mild side wind and then sets the trim controls to do it for him so he, or she, doesn't have to constantly monitor this steady force.
You trim the control surfaces of the airplane such as the elevator so you don't have to keep applying pressure on the yoke and thereby keeping your arms from tiring.

They are used to propel the airplane forward to get air moving across the wings. When air moves across the wings lift is created and you take off. Another interesting note: A propeller is an airfoil just like a wing is.

They make the airplane more versatile, less expensive, or both. A similar question is, "now that they have jet airplanes, why do they make propeller planes at all?" First, a propeller plane is less expensive than a jet. Let's give you six million dollars to buy an airplane, and make you buy new. $6 million gets you an entry-level jet. It will carry four executives if they restrict themselves to one suitcase each. The same $6 million will get you a Pilatus PC-12 or a Beech King Air B200, which are basically small airliners, or it will get you two EADS Socata TBM 850s, three Cessna Caravans, or three Piper Meridians. And that's just turboprops--$6 million will get you about a dozen piston planes. The other reason, and this is more important for a lot of operators, is that the propeller plane is more versatile than a jet. You can land on unimproved airstrips. You can land on top of mountains. In Mel Gibson's movie Air America there's a scene where he lands a Pilatus Porter on the side of a mountain--the real Air America pilots in Southeast Asia did that a lot. Jets, unless they're built for the military and equipped for rough airfield service, have to fly onto paved airstrips. Airbus is busy designing the A400 military transport. It has four turboprops. The drawback of a prop plane is that it can't be very fast--if you need a plane that flies faster than 400 knots, you need a jet. Prop planes don't fly as high as jets do; a King Air will fly up to 31,000 feet above sea level, while business jets routinely ply the skies above 41,000 feet. Propellers are not used to force air across the wing. they are used to create motion. In other word make the plane move and it's the resultant forward movement that moves air across the wing to create lift and get the plane off the ground

To make a Trebuchet like Yesteryears, they used more then one component, wood, rope, metal, to make a trebuchet out of one component would be difficult if not impossible. BUT: your 2 fingers, a rubber-band, and a tight raped piece of paper is one way. If you want to mimic Trebuchet"s of old, spread glue on paper and roll it real tight for your up-rights, braces and arms, use string and glue to bind together, use a rubber-band for your resistance. You should have a picture to guide you. (I hope this helps)

Aerodynamics teaches us that the heavier an object, the faster (more energy) is required across the wings to achieve lift. Moreso, the material that a plane is made out of has a limit to the amount of force it can handle. There will come a point where the plane can no longer overcome the force of gravity on it's mass.

it is heavier and fly lower it is heavier and fly lower it is heavier and fly lower it is heavier and fly lower more weght at the nose is better

I was an Radio/Radar repaiman in the Air Force and trained on the "Q-13" Radar, then worked on them at the AF Depot, Tinker AFB, Okla. It was the primary airborne radar system in the early - mid 50s. They were used on the B-17, B-36, XC-199 (Cargo version of the B-36), C-54, KC 97, C-119 and C-124 among others. The antenna was a parabolic dish that was mounted in the nose of the plane and swept back and forth, scanning 45 degrees in front of the plane. It could be switched to make a full rotation. At Tinker we used a bench mounted set to track Sputnic. We had to do a slight mod to extend the tracking distance from the normal 200 miles.

Because the air gets thinner with more altitude, and at some point the thin air can no longer give enough lift for airplanes to stay aloft.

Start by crumpling all the paper into a big ball. Use the tape to help you keep the crumpled papers together as best you can. You may have to experiment with varying degrees of paper compression. You may have more control of rigidity and landing if you fold the paper like an accordion bellows and layer them criss-cross. The tape could help you control rigidity. The more even surface may help keep the egg from breaking by bouncing or rolling off. Feet are also on your leg. You also walk with feet!!!!!

There are two methods for weighing airplanes. The first is to actually put the airplane on a set of scales, one under each wheel, and determine the weight that way. The other, common for large aircraft, is to calculate the weight. When a new aircraft is certified by the FAA, it is actually weighed at the factory and an empty weight is determined for each model. The aircraft weight is then recalculated for any changes made to that model. When an airline buys a fleet of the same model aircraft, it determines a basic operating weight (BOW) for the fleet. BOW is the empty weight of the aircraft with the weight of normal operational stores added. These include such items oil and other fluids, spare parts, galley stores, emergency equipment, normal crew, etc...basically, everything except fuel, passengers and cargo. When an aircraft is ready for a flight, its weight is determined by starting with the BOW and adding the actual weight of everything that has been added to the aircraft for that flight. These normally include the actual fuel load, the weight of the passengers (either actual weights if the flight is critical, or average weights if not), the actual or average weight of bags, and the actual weight of the cargo. The end result is the aircraft take-off gross weight (TOGW), which is then used to determine the expected performance of the aircraft (how high it will be able to fly, how fast, etc.). The en route fuel burn is calculated and then subtracted from the TOGW to get landing weight which is used to determine landing performance (how much runway will be needed, stopping distance, etc). Hope that helps.
