UAVs?

I was building my 4d rc plane, and then i thought if i could build a rc conputer controlled uav, and fly it over the neighbour s house, and with a pan and tilt camera, it would be nicer. and i don't even need to go to the flying field. I was wondering, if i could make a rc plane with more than 1 hour of flying time and can fly with a range with 20 kilometers that would be the perfect model. How is it possiable to make a light yet powerful plane.  pls help me with this project ps.i have a budget of 400 dollars.

Tiltrotor UAV?

So, a friend and I were looking at something NASA published a while ago. It was a call for a tiltrotor craft that could carry 55 people, could land either in water or on land, and could suck up water for use in firefighting. It was also meant to be a civilian craft. Anyway, we started to get an idea in our heads about designing some sort of tiltrotor rc thing or perhaps a UAV. We're both mechanical engineering majors and have some experience with aerodynamics, programming, electronics systems and rc aircraft. I was wondering if anyone had some good suggestions as to the design of this. One of the things we weren't quite sure about was what we would use for a power supply. Appreciate the help. *Note, if we actually build anything it will only be a small scale proof of concept prototype built from inexpensive parts.

UAV from scratch and radioshack?

I see that Radioshack is going bankrupt and is closing its stores so they are having a closing sale. So i was wondering is it possible to build a UAV from parts bought at radioshack to take advantage of its sale? Can someone point me to a guide or instructable or 'how to' to build a uav from radioshack parts?

Remote Control UAV help?

I want to build a small UAV system with a limited budget, ~$350. I like it o transmit live video feed to a ground station with ~2 mile range if possible, and to record the video as it is being taken. A plane recommendation would be nice, but I figured i would buy a rather cheap one and upgrade the transmitter / receiver. This might be possible, or it might just be out of this world, any info will help, thanks.

I've found a UV/Black-light flashlight thing, What should I do with it?

I was digging through some old stuff when I found this flashlight thing. The top is an actual flashlight (broken), but there is a (working) black-light running down the side. Is there anything cool I can do with it? Or build or something?

Turnigy 9X not working?

I have a Mode 2 Turnigy 9X transmitter for my quad-copter (3DRobotics APM 2.6) and it worked almost perfectly at first for a $90 controller. After not using it for a while, I tried using my quad-copter and it wouldn't arm (start). I plugged it into my PC to check the transmitter settings in the APM program and the sticks do not work anymore. The left stick does not show movement values at all and the right stick (throttle) does not go to the lowest value (~900) anymore, only to the highest. The left stick is what is used to start the quad, which is why it wouldn't start in the first place. Why would the sticks suddenly stop working? Also, about a week earlier, a screw fell out of the inside of the transmitter (heard it rattling inside). Would this have anything to do with it?

what kind of cameras do military uav's use?

You know Call of Duty 4, in the AC-130, or in any helicopter, they have the white-on-black image, possibly nightvision or IR, that isn't the best quality but gives it the targeting computer look? What is that Called?

ESC zero throttle power consumption? Answered

I have heard that an electronic speed controller (esc) uses some power continuously even at zero throttle. What I was told was about 0.5 amps, but it seems like it would be different based on size, voltage, etc... My UAV has two 20 amp ecs's being powered by two 4.4 Ah 11.1 volt batteries and it will need to land and sit with the power on for 3 hours after flying 2 miles and then fly back. At 0.5 amps the 3 hour sit will waste 3 Ah. I will probably need to set it up so the esc's are unpowered at zero throttle but everything else will remain powered. Does anyone know a way to calculate about how much current the esc will burn at zero throttle if you know what battery, esc, and motor you have? Or do I need to measure it directly to know?

Google boss concerned about privacy??

One coolest pieces of technology in the hands of independent Makers is the UAV; students and hobbyists can exceed military spec for drones and quadrocopters for a fraction of the cost.  So it concerns me when Eric Schmidt, head of the company that put millions of people's homes online without asking, and has been fined in several countries for harvesting personal data via wifi, trys to influence American policy makers, invoking the demon called Terrorists Might, so that the use of UAVs is restricted on thd grounds of "protecting privacy". What say you, Makers? http://www.bbc.co.uk/news/technology-22134898 Image of Eric Schmidtvfrom AP via BBC site.

Antenna Tracker Pointer using GPS

I want to build a systems that can point a directional antenna to a known set of GPS coordinates, because if the base unit with the antenna knows it GPS location and then can have the know data of another directional antenna's GPS coordinated either via Google Earth File or a spread sheet or long/lat's or via another method....also I would like this system to be able to track a UAV or R/C plane/copter as the DIY antenna trackers do as I have seen on R/C forums and You-tube. the initial request is what I desire first....I want to go out into a field and set up this tripod mounted Pan/tilt mechanism with mounted directional antenna(s) and point it to the closest fix antenna of known coordinates, automatically.

Use a computer game to control an RC plane? Answered

Is it possible to use a program like Flight Simulator 2000 to send radio signals to an RC plane? The game can take messages from a joystick and convert that to "move ailerons," "throttle up," etc. If it is possible how can it be done? For a contest I am thinking about entering I need to build a vertical takeoff/landing UAV that can fly out 2 miles beyond line-of-sight, send back live video (or possibly a buch of still pictures) of an area for up to 3 hours, and return to a different spot than where it started. I don't know where to get radio equipment that can go that far except expensive 900MHz stuff. Some walkie-talkies claim to be able to go that far but I don't know if they can send a signal useable for something like that. So I was thinking of having my drone drop a thing half way that could pick up, amplify, and re-transmit controls to the UAV, and video (+mabey some tellemetry stuff) back to the controller. Is that possible?

micro electronics

Basic of this post is where e to buy micro size electronics for micro flying drones which are insect size? I asked arduino and raspberry pi, no answer yet.  in this post : https://www.instructables.com/id/3D-Printed-Ornithopter-Micro-UAV-Drone/     there is electromotor which OP claim that was used also by inventor of little flying drone...regarding arduino uno board i am not sure that was really used by inventor, please see pictures and videos on youtube....so if someone knows please post where to buy such micro size electronics. Thank you

Record Solar Powered Flight

UK-built solar-powered plane has set an unofficial world endurance record for a flight by an unmanned aircraft.The Zephyr-6, as it is known, stayed aloft for more than three days, running through the night on batteries it had recharged in sunlight.The flight was a demonstration for the US military, which is looking for new types of technology to support its troops on the ground.Craft like Zephyr might make ideal platforms for reconnaissance.They could also be used to relay battlefield communications.Chris Kelleher, from UK defence and research firm QinetiQ, said Unmanned Aerial Vehicles (UAVs) offer advantages over traditional aircraft and even satellites."The principal advantage is persistence - that you would be there all the time," he told BBC News. "A satellite goes over the same part of the Earth twice a day - and one of those is at night - so it's only really getting a snapshot of activity. Zephyr would be watching all day." The latest flight was conducted at the US Army's Yuma Proving Ground in Arizona.The Zephyr flew non-stop for 82 hours, 37 minutes.That time beats the current official world record for unmanned flight set by the US robot plane Global Hawk - of 30 hours, 24 minutes - and even Zephyr's own previous best of 54 hours achieved last year.However, the Yuma mark remains "unofficial" because QinetiQ did not involve the FAI (Federation Aeronautique Internationale), the world air sports federation, which sanctions all record attempts.The US Department of Defense funded the demonstration flight under its Joint Capability Technology Demonstration (JCTD) programme. The 30kg Zephyr was guided by remote control to an operating altitude in excess of 18km (60,000ft), and then flown on autopilot and via satellite communication.It tested a communications payload weighing approximately 2kg.At first sight, the propeller-driven Zephyr looks to be just another model aircraft, and it is even launched by hand. But this "pilotless" vehicle with its 18-metre wingspan incorporates world-leading technologies.Its structure uses ultra-lightweight carbon-fibre material; and the plane flies on solar power generated by amorphous silicon solar arrays no thicker than sheets of paper. These are glued over the aircraft's wings.To get through the night, the propellers are powered from lithium-sulphur batteries which are topped up during the day."A lot of effort has gone into power storage and light-weighting the systems," explained Mr Kelleher. "Lithium sulphur is more than double the energy density of the best alternative technology which is lithium polymer batteries. The engineers from the Farnborough-based company are now collaborating with the American aerospace giant Boeing on a defence project codenamed Vulture.This would see the biggest plane in history take to the sky, powered by the sun and capable of carrying a 450-kilo (1,000lb) payload.US commanders say the design must be able to maintain its position over a particular spot on the Earth's surface uninterrupted for five years. QinetiQ is the public company that used to be the British Government's military research department, before they privatised it.BBC articleQinetiQ's page on Zephyr
