I just had a great Idea last night. Okay, I think we've all seen those $250,000 homemade flight simulators built by people with just a wee bit too much time on their hands (like anyone who goes on instructables). One of the main reasons these are expensive, other than the computer themselves, is the fact that there are multiple LCD screens surrounding the pilot. These things cost a few pretty pennies, so this is where my idea comes in. The first thing you would need to do, would be to arrange some semi-opaque plastic panels where you would usually have the LCD displays. They need to be opaque enough that you can't see through them, but clear enough to let a good bit of light through. In other words, they need to be translucent, not transparent. The second thing would be computer software. It needs to be able to totally invert your desktop display. You could do this with hardware, but it would be a waste of time and materials. Connected to your computer would be a digital projector, which is where all of the magic of this project comes together. You run the projector through a prism (what kind, anyone?), to slightly warp the projected image. You need this warpage (is that a word?), to counteract the different angles of the plastic panels. The projector is set up in front of the "cockpit," projecting its inverted, warped image at it. You can see the images on the inside, because you chose the correct opacity, right? The hope behind this idea, is that it is much cheaper to have 1 digital projector, than it is to have multiple LCDs. Thanks! MDJ

All of us have seen humans fly in those triangle shaped gliders. How about creating wings that will do the job? Understood that it requires more than wind to propel it so flapping power could be harnessed. I need designs and the physics(i.e How much area of wing is required to lift what mass of body and etc.) Please suggest solutions ASAP! My e-mail id is email@example.com Thank You :D

If you download the most recent version of Google Earth and press Ctrl+Alt+A it will open up a flight simulator. You can select from two different planes and take off from several locations including San Francisco, Switzerland, and the Himalayas. You can also start your flight at a specific location if you go there in Google Earth outside of the flight simulator, and then select the "start at current view" button which is above the airport selection box. The controls can be found by going to help and then clicking on keyboard shortcuts. It's a lot of fun and has pretty good resolution. The pics are of the Himalayas.

Seeing as knex is light, strong and flexible, and most importantly, using rods, I beleive it would be feesable to build a Knex 'glider'. After seeing how gliders are made, it could be possible to build a lightweight spacframe wing out of knex, and make it fly using clingfilm as its 'skin'. An extra boost of gliding power would come from a clingfilm propeller, powered by the very fast and smal, solar motor. Do you think it is possible to make something like this glide 10 metres? Ideas welcome.

Have you seen the videos for Flugtag? It looks like a great excuse to build something fun and jump in the water, and maybe fly a few feet too.Most of them look like this: And here's the US record holder, at a whopping 155 feet: I bet we could do better than that, especially with a drop. ;) Anyone have a proposal for Team Instructables? They hold these things around the world, so it's not just US. I bet we could pick up on style points as well.From the official page:The first Red Bull Flugtag took place in Vienna, Austria, in 1991. Since then, more than 35 Flugtags have been held around the world -- from Ireland to San Francisco -- attracting up to 300,000 spectators. The record for the farthest flight-to-date currently stands at 195 feet set in 2000 at Flugtag Austria. The U.S. record stands at 155 feet set in Nashville, TN in 2007.Teams are judged on three criteria: distance, creativity and showmanship. What constitutes a craft is purely up to the imagination of the participating teams. Past Red Bull Flugtag entries have included a pregnant cow, a diaper-delivering stork, a pimped-out Cadillac, a giant Oompa Loompa, and yes folks -- a lobster named Larry.

After the success of the last contest, Gmjhowe, =SMART= and myself decided we'd go for it and launch a second contest.The first we really enjoyed and saw some awesome entries. This time we've decided to make the guidelines a wee bit looser so you can use your imagination more. We'll be setting a category for you to design and build within and then provide you with some example ideas to get you started. And this category is....FLIGHTAnything plane, helicopter, glider, flight related is allowed. Please read the rules carefully.Rules:Your entry must do something. It can't just be a model of a plane or a helicopter. We want them to move or glide or have spinning parts or be functional for something else around the house but be aircraft themed.Entries must be over 50% knex. The remaining can be paper, glue, card, tissue paper.... anything!To enter, write up a full instructable of your construction process with clear pictures and descriptions. Post the link here.Please steer clear of guns. That's not what this is about.Starting and closing dates are GMT.What the judges say goes!Have fun!Judging - 12th Sept - 18th SeptSuggestions:A propellor. Small and compact, if you design a good one you might get extra kudos if your design's then used in loads of other entries.A ceiling plane. With a plastic propeller on the front and the top attached to a string to the ceiling, this plane will fly itself around in circles on a string.Paper plane launcher. Probably the closest you'll get to a gun.A vertical launch rocket. Rocket being a rocket model not a meagre collection of rods.While knex by itself might not be light enough to fly.... perhaps you could run some string through the middle to make it appear to glide.... Mum's washing line might be of great help.Prizes:There will be patches for prizes. Gmjhowe will be uploading them soon.

I am making a quadcopter and I am in some confusion. I am planing to get a KKv3 Flight Control Board from Hobby King. The question is, if I get the board then what is the need of getting a seperate IMU6050 as I have seen in some projects that people have used the 6050 sensor along with the Flight Control Board. Is it necessary to use that? As the flight control already have sensors on them. Also, does the flight control board gets connected to the arduino? and if so then how?

I was thinking about building a flying car that would have most wingspan hidden under the car (pops out when activated) and the doors would be the tips. (What used to be the back doors would roll over van-style, and the back would otherwise be covered by sheet metal) In the back, there would be two vertical rudders and the spoiler would be cut into flaps for horizontal rudders. The thing would overall be powered by two helicopter jet engines. Once the flight system is activated, the gear shift (auto trans) would turn into the throttle, and the gas/brake pedals would turn into the rudder pedals. The idea is to make a flying car that still (when wings are stowed and trunk cover is closed) looks like a normal car. The question: is this possible?

Ok, so I have another idea that will most likely never get anywhere due to my lack of funds/it not being possible. What if I made a magnetic track somewhat like a maglev and had a robotic pegasus with electromagnets in its feet. It would also be an ornithopter to get it farther than a few inches off the ground. I would have the magnetic track to have it hover a few inches off the ground for about a minute before and after takeoff to make it less likely to crash on landing and give a minute to text the mayor to not worry about any upcoming pegasus sightings above or around town before taking off. What kind of horsepower engine would I need to power the wings enough to get sufficient lift (at least 15-20 feet)? And would the electromagnet buffer before landing be significant enough to at least lessen the impact so it doesn't maim/kill you if you crash? The electromagnets don't seem to me like they would work, but it would still be fun just to hover it to show it off without flying up 20-30 feet and worry about falling. Also, would it make it too heavy to fly if I put in an extra motor to make it walk/run so it doesn't have to be flying to move? I don't really expect this to be within my budget, but it would still be cool.

I know I will not be able to completely rely on solar power to power the blades of my quadcopter but I would like to extend the flight time as much as possible. I was looking at this url and started getting interested in trying to create a small panel array on the arms of my quadcopter to help replace some of the power in the battery (trickle) while using the battery for flight. Doug Paradis had some helpful insight to the OP's question but some of it went over my head. That's what lead me to ask my own question to make sure I'm talking about quadcopters instead. So currently I have a light weight POS starter quadcopter that has the following battery being used... - FB752540 - 136 Li-Po - 500mAh 3.7v - 4K07 1.9Wh I have some internal space to mount small items but I would try to keep the weight down as much as possible. I was hoping to start my own DIY project to learn more about solar power and the entire process. I'm guessing I would need at least one solar panel (small), something to convert the power, and some type of regulator to trickle the power into the battery. Any ideas as to how I would do this? Thanks! Arvo

The Martin Jetpack made its first public flight while at EAA AirVenture Oshkosh 2008 on Tuesday. The actual flight lasted seconds and was confined to a few feet off the ground, with handlers gripping the device even as 16-year-old Harrison Martin manipulated the controls. The Martin Jetpack team is scheduled to conclude Thursday's air show with another flight at the mouth of AeroShell Square. More air show flights may take place later in the week as well.Today this jetpack was demonstrated at EAA AirVenture. It seems like the closest thing yet to one that is actually marketable: it has flown a demonstration flight in public, and a CNN reporter was able to handle it after minimal training. Rather than a finicky rocket that burns hydrogen peroxide, it uses a gasoline V-4. It's also considered an ultralight, which means very minimal regulations.Darn it, I could have gone to AirVenture, and I decided not to this year!Linky.

First posted here. Last Friday, I drove up to Maryland to see UMD's Gamera II human-powered quadrotor. They are currently pursuing the Sikorsky Prize, established in 1980. Here's the team testing a new control system. http://youtu.be/3B2of4V35d0 (sorry, the embed function isn't working) During this test, Gamera II flew for approximately 65 seconds, unofficially tying the endurance record that the team previously set. This flight time, plus the ability to remain within a specific boundary, satisfies two requirements of the Sikorsky Prize. Because the rotors are so close to the ground, the helicopter is benefiting from a cushioning effect of the air between the rotor blades and the ground. This effect will diminish exponentially when the team attempts sustained flight at the required 3 meters. The helicopter transfers the pilot's pedal power by unspooling cable from pulleys, mounted on the shafts of each of the four rotors. Flight time is limited by the pilot's stamina and the amount of cable stored in each pulley. The rotors are constructed of carbon fiber, balsa, and foam, and are covered in a plastic film. All in all, it was a cool experience. I've never seen so much carbon fiber in my life! I look forward to seeing the team win the Prize.
