A paper airplane got to have wings that are slightly curved (convex) on the surface facing upwards and straight at the surface facing downwards, so that when chucked , the air flowing over the wing is faster than at the bottom.This creates a lift (because of low pressure above the wing – see Bernoulli’s theorem for the science and the math).
The airplane that you and i fly in has engines to generate thrust to move forward, and the wings to create the lift in the manner described above.
In a paper airplane, you provide the initial thrust when you chuck it.
Obviously various factors determine how high your airplane can fly including weight, wing span, air friction on the paper, shape of the plane,speed and angle to horizontal at which you chuck the plane, wind speed etc.

Im new, i would like to know what a good plane is to start… i know i can fly because when i was in bc my friends friend let me fly… it was amazing…..
Im willing to spend 500$ i want it to be nitro..only.. to fly longer pierods of time…. what do you guys recommand
I need to have every thing radio. gyro… i would like 4 chan controler…
A good place to start is with any kind of super-durable trainer plane.
I started with an Airmadillo, and then a Durastick. They both are both 4 channel trainers. I have a 6 channel in my Durastick, and added a camera to take aerial photography with it.
Both use corrugated plastic for wings, and have very strong bodies. The body of the Durastick is actually made from PVC eaves trough pipe.
The Airmadillo is probably one of the ugliest planes available. They arrive in a kit, and you can have them RTC (Ready to Crash) in about one evening. When you crash, and you will, you can usually just throw on a new propeller and wipe off the dirt and you’re ready to go. And they aren’t the worst planes for aerobatics either.
I started with this one:

And have flown this one as well:

Unfortunately I can’t find a link for where I purchased my Durastick, but I found a video on youtube of people flying one similar to mine:
With 2012 fast approaching, I have a plan to save tens of thousands of people. I need your help to write your Senators and Congressmen and ask them to fund my project.
My Plan
I have designed a new launch vehicle called the ‘Jocket’ because it uses both jet and rocket engines. Here are the numbers that show it will work.
1. Dimensions: 180 ft long, 180 ft wing span, fuselage is 30 ft wide by 30 ft tall. There are 3 sections: 20 ft long crew cabin, 60 ft long cargo bay and 100 ft long main engine
2. Made entirely from carbon and Kevlar composites requiring 9000 square yards of carbon weighing 6188 lbs, 1000 lbs of Kevlar plus 5700 lbs of Nomex and resin = total: 12,888 lbs.
3. Metal components, view ports, life support, computers, radar, radios & TV, controls, displays, crew seats, etc will weigh = 24,500 lbs.
4. The 2 jet engines, GE90-115Bs, produce a total thrust of 230,000 lbs to fly the Boeing 777-300 that weighs 775,000 lbs. total weight: 36,520 lbs.
5. Jet fuel will be carried in 2 wing drop tanks & 2 tanks inside the wings, the total fuel is 1800 gallons, weight = total: 12,312 lbs.
6. There are 2 model M-V-1 booster rockets strapped under the wings. Their combined thrust is 1,699,710 lbs. They weigh a total of 368,420 lbs.
The net thrust is 1,331,290 lbs which will accelerate the ‘Jocket’ to nearly 17,000 MPH and an altitude approaching 180 miles. After burn out, the boosters will be jettisoned to parachute to Earth for recovery and reuse.
7. The main engine is a nitrous oxide/HTPB hybrid (used in Space Ship One to win the X-Prize) that weighs: 200,000 lbs. It will boost the ‘Jocket’ into orbit and help bring her home.
The total launch weight of the ‘Jocket’ – less cargo – is 654,640 lbs. The 2 jet engines normally lift 775,000 lbs into the air, giving the ‘Jocket’ over 120,000 lbs of excess launch thrust that could be used for cargo. However, the ‘Jocket’ is designed to carry only 80,000 lbs of cargo, so there is a safety margin.
What do we do when we get into orbit?
I’ve designed the Inflatable Habitat Module. You’ve seen those inflatable structures kids get in and jump around in, well think of that but larger.
The Inflatable Habitat Modules are like very large double walled balloons. Instead of rubber, the outer wall is made of Kevlar, carbon, Mylar and netting, like a large bullet proof vest. The inner wall also uses Kevlar, carbon and netting with the addition of an airtight layer to keep the air in.
The 2 walls are spaced 4 ft apart. The netting helps the 2 walls keep their shape and maintains the space after they are inflated. After inflation, the 4 ft space will be filled with 2 part expanded foam insulation that will set up and harden to create a solid walled enclosure.
My plans call for rectangular box Modules that are 100 ft wide by 300 ft long by 50 ft tall with an interior space that is 92 ft wide by 292 ft long by 42 ft tall. Three interior divisions will create 4 floors that each have an area of 26,864 square ft for a total of 107,456 square ft.
The next step is to start connecting Modules end to end until you have a ring of 20 Modules. Then you make the ring 5 Modules wide and finally you stack them 5 Modules tall for a total of 500 Modules.
The plans call for 200 Modules to be used as living space for 50,000 people. There will be all of the amenities found in a small town – schools, hospital, recreation, entertainment, a library, parks with plants and so on. One or 2 Modules will house playing fields for football, softball, soccer and other games.
200 Modules will house both hydroponics and soil farms for growing food, raising livestock and everything else to feed the occupants and maintain a breathable atmosphere. Several of the Modules will house groves of fruit & nut trees, a ‘forest’, vineyards and even a lake/pond (for swimming, fishing, fish farming & water storage).
The remaining 100 Modules will be used for storage, life support, power, station maintenance, recycling and other things.
In order to accomplish all of this well in advance of 2012 we have to start now. It will take time to build the ‘Jockets’ and the rocket motors we need. Sewing together the Modules is the easy part, its setting them up and transporting all of the supplies, equipment and materials that will take time. But it can be done if we start now.
If you support me, believe in what I’m trying to do, then write your Senators and Congressmen now. Ask them to support my plan.
You all want to know who will be saved and how much willit cost me. I’ll start with the list of supporters – people whoworked to get me the money. There will be space for 50,000 people. One hundred positions will be for essential people: doctors, dentist, nurses, surgeons, veterinarians,teachers, astronauts/station builders, electricians, machinist, maintenance, farmers/hydroponics experts, etc.
The remaining 49,900 will be chosen by a lottery operated by an outside company. Money will not buy you a position on board the station. For the people chosen by lottery, the good news, it won’t cost you anything, except for the clothes and other things you want to bring with you. One last thing, pets are defiantly welcome, in fact you are encouraged to get a pet – anything but fish.

I am a power engineer. I’ve spent several years on the Jocket design and the idea for the Habitat Modules.
I believe something bad is going to happen on 2012, that is why I am asking for your help.
I am open to and ready to answer your questions. Please send them by Email: jocket@peoplepc.com Thank you.
