Hi, I'm looking for any information on ultralight aircraft. How they're built, what engines they use, plans/designs, ect.

I have always wanted to grow a dwarf fruit tree or tropical tree (10-15 ft tall), but living in a townhouse I don't have room to winter a tree indoors. I was wondering if anyone has ever heard of this being done for a single tree? Kind of like a "tree phonebooth" for winter, potentially with a heater run from my outdoor electrical outlet. Any thoughts on where to start? If we can get a theory together I will build it and post it.

I don't, 'camp.' I backpack. There's a clearly distinguishing difference between what most people call camping and what I do. What many do. Most people who camp don't bother to build stuff from cans and twigs and bottle caps to shave grams. Most people who camp don't seek out a murky pond as a possible water source. Most people don't have to dig a cat hole. Most people don't have to hump in gear. For those of us that do, we tend to have a knack for ingenuity, craft, innovation; and style, if it happens. Backpacking is a philosophy -- the study of the art and science of living as comfortably as possible, with as little as is reasonable and as often as possible, in a place that wants to kill you. Camping is a vacation. I recently posted an instructable for an ultralight backpacking kitchen. I posted it for the sake of people who do what I do, not someone who sleeps in an Eddie Bauer sleeping bag on a Coleman double-wide air mattress. Not that there's anything wrong with that... It just ain't my bag of pool balls. It should follow that 'backpacking' be a sub-category of 'camping.'

OK so I have seen many Instructables on making an ultralight alcohol can stove, but not of them compare fuels. I have heard of many types of fuel being used, all the way from denatured alcohol to everclear drinking alcohol. I want to know which type is easiest to obtain and produces the least amount of soot on pots. Thanks in advance, Junits15

I have always wanted to construct an ultralight aircraft with this old rowboat I hooked up some shocks and wheels to, I even have the hang glider, I need a way to connect it while giving me the ability to steer properly.

i know ultra lights nomaly use gas , but i was thinking in one total eletric . why? cuz its green , easier to make , easier to control, easier to repair , and several others things. but it have a problem(of course it have a problem why air companys dont use eletric planes) . so i get to the conclusion it have to be light (that means small to), and the electric motor would have to be efficient. so i think what plane i use ...... the aswer is the mc-15 or cri cri if u like that name is light allready have a eletric version(a crap flights for15 minutes only , but faster than the gas one) .(UPDATE) ok to power the motors 4 of 24 volts i was thinking in a fuel cell aka hho cell. how i make thata fuel cell i already see instructables but it have to make 24 volts and turn upside down . im searching 4 a good fuel cell blueprint.(UPDATE)

In reading some of the instructables on DIY projector lamp replacements I decided to give it a shot. So I purchased a Proxima Ultralight LX1 off of ebay, and when it arrived it contained no previous bulb, so I purchased a MR16 style 100 watt halogen bulb and installed it (with a seperate power supply). When I started it up and connected it to my laptop it worked fine for about a minute or so (give or take) but then the image went blank (not the bulb but the LCD screens showed blackness) for five seconds, then the image popped up as nothing had ever happened. I have tried everything to prevent this, other computers, killing the ballast (which is quite easy, only one wire to disconnect) different video sources and no dice. But I do know that it has nothing to do with the light bulb because it is on a completley different power supply and is not connected electronically to the projector in any way, there is something wrong with the controls of the unit Any Help would be appreciated, Thanks Bwpatton1

For a while i've been studying, designing, and building hang gliders. To my great disapointment however, none of them have even glided. I am starting to think there are more things to consider than just center of gravity, balance, and the over all "lightness" of the craft. Are there more things i should consider? I have also pondered upon the idea to make a Ultralight Helicopter, or somthing along those lines. What are some things i need to consider beond what i've already mentioned?

I am trying to build an enclosed ultralight aircraft similar to the Cri-Cri made by michael colomban. I think i can make it around 100 or 150 pounds. I have an engine that is somewhere between five and ten horse power. i could possibly get another one of relatively the same amount of power. i have read about the DA-11 made by leeon davis that ran on an 18 hp engine, but is there a way to calculate weight vs. hp so i can be sure it will fly? (;

Hello Instructables I am a professional aerospace engineer who homebuilds aircraft in my garage when not doing so for work. I live and work at the Mojave Airport which is a hotbed for aircraft homebuilding stretching all the way back to the 80's. The experimental aircraft community does not have anything like what you all are doing on this website. When I found your site the first thought was that I had finally found the place to talk about buillding airplanes. But I see no such topics on the site. While fundamentally I assume the problem is only that the channel has not yet been created or there is a liability problem, I wonder if there isn't more to it. Is the thought of designing and building and flying your own airplane not as awesome for others as it is for those of us who live in Mojave? Is there something that can be done to make this exciting world more exciting to people (like yourselves) who take such pride and make such investments in doing cool stuff in your garages?

I am wanting to build a personal ultralight helicopter. First issue here is to find a suitable engine. Outboard motors have the 40+ horsepower I need and can be found pretty cheaply on places like craigslist. One thing I know about these engines is that they use a water pump to suck up water and cool the engine. It is important that this water is present and can the engine can be wrecked if it is run without water for more than a minute or two. Short of including a water tank on this helicopter, do any of you have any practical solutions to keep an engine like this cool? (Just so you know, an "ultralight" helicopter must weigh under 249 pounds without the passenger. In the US, you can fly ultralights without a pilots' license. 40hp outboard motors weigh around 160lbs so I don't have a lot of room for heavy water.)

Christy gave me the 400 piece Value Tub of K'Nex. I've built the ultralight, and it wasn't particularly rewarding. So, which guns can I build with the pieces I have? I took a picture of the parts list so you can see what I have to work with.

So i thought i'd start a thread on Metal foams. For those of you that don't know what it is i offer the following links: http://en.wikipedia.org/wiki/Metal_foam http://www.metalfoam.net/ Looking through the forums, I figured this could be something pertinent to a DIYer's interest, since metal foams, specifically Aluminum foam, is strong, light, and relatively cheap. The fact that it marries with advanced composite materials science is kind of an added secondary bonus. I'm personally interested in this sort of stuff because i want to make an ultralight aircraft and this stuff could be used to accomplish that... but that's sort of something that's tangental to most that'd find info on Foamed Aluminum interesting.

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.

Australian Christopher Malloy has built what seems to be a working hoverbike. Built in his Sydney garage, with a custom carbon-fibre frame and a BMW engine, the machine is being touted as "Star Wars Speeder bike Mk1". Currently restricted to tethered flights of a few inches altitude, Malloy claims the bike feels stable, and is just waiting permission to undertake untethered tests. 'I am still ground testing at the moment only because I'm not 100 per cent sure what will happen so the straps are there to cover the unknown. I haven't had the pleasure of flying round the countryside yet. 'It is quite stable and doesn't want to tip over but if something unplanned happened during testing I wouldn't want to break the prototype. 'The Hoverbike was built with safety in mind so at least three components have to fail before you might have a serious airborne failure. 'There are also two explosive parachutes attached to the airframe and of course the rider could choose to wear their own parachute too. He predicts: 10,000ft altitude. 100mph 92 mile, 45 minute flight on one tank £45,000 pricetag The hoverbike should also have "ultralight" status - at only 270kg, under US regulations, no pilot's license would be required. Since it has no driven wheels, it shouldn't require a road license either...! Malloy is a former helicopter pilot, and says those skills are helpful when flying the hoverbike, but also says that the unique craft ultimately needs no more skill to fly than a motorbike, with speed and direction being controlled by a mixture of throttle and body-posture. As soon as I win the Lottery, I know who is going to get a knock at the door... Via Daily Mail
