About Me:
UAV enthusiast at large, software developer by day, serial entreprenur by night, father of 2.
Please tell us a bit about your UAV interest
Been into fixed-wing foam with Paparazzi for a couple of years. Currently dabbling in multicopters, learning ArduPilot as part in the CanberraUAV team (2012 Out Back Challenge, here we come). http://www.CanberraUAV.com/ I also sell Paparazzi hardware from my secret underground lair: http://aerofu.com/

"What you want is called a "string cage". I use a big (20l) paint tin with a rim-clamp, and short lengths of light cord. Fasten one cord to each arm near the motor. Hold the quad above the can lid, a bit less than one arm-length above it, and trap…"
"re-purposing ear plugs might be better than butchering other peoples laptops. You can get the Brussels sprout flavoring off them with detergent (or just use new ones)."
"@Shayam, if you want to experiment with quaternions, DCM, euler angles, etc. you might want to check out the various pluggable AHRS subsystems in paparazzi.

"In AU, "pilot in command" has a legal definition. It's the person responsible (IANAL, that's just my understanding of regulation CASA 101).
It's not a badge of honor. The only time you fly and are not the pilot is wham you are flying with an…"

"The terms are only interchangable if you use them imprecisely. When the first sentence of the Wikipedia definition says "region of space", it means volume.
I didn't exactly ignore aerodynamics of lift, I said 'magic 100% efficient propellers'. The…"

"longer props have a higher aspect ratio (better lift:drag ratio, more lifting force for a given ammount of work. i.e. better prop efficiency). But longer props require a bigger frame, which is more weight.
Higher voltage batteries/motors means less…"

"No no no no. That post by Chris Anderson related to a totally different autopilot, and it was factually wrong! That post was about the Lisa family of paparazzi autopilot hardware (which has always been open source despite the misinformation early in…"
"@Nick V,
I hear you, I had the same experience (ordered on day 1 then was annoyed by "processing" for a few weeks before it shipped), however it did arrive soon after that and the hardware is fine, no problems. I'm relaxed about it now, this is just…"

I'm not sure "firmware" is the right word for it, but those PixHawk guys have their own software stack. At the bottom they have an operating system called NuttX (a type of real-time UNIX). On top of that they have device drivers and such…"

"These look great, especially great if they usher-in an age where different open source UAV platforms (Ardu*, Pixhawk/NuttX, OpenPilot, ChibiOS, Paparazzi, ...) can be used on the same hardware. Exciting times!"
"Is it very cold? I have similar setup (APM1, rctimer motors and escs) and it works fine in warm weather but the escs seem to go crazy in the cold (e.g. -4 centigrade)."
"Of course what akimarain and Luke say is true, but it's also true that you can make inneficient things fly well enough to have fun using basic heuristics and experimentation, without computatuional fluid dynamic simulations or anything like that. If…"
"A few comments suggseting this wouldn't be an issue with air modules (UART), only the ground module (with inbuilt USB adapter). Is that right? Or is the interference coming from the Bus, rather than the adapter?"
"Hi Klaus, I don't understand your question. Are you asking about formation flying (формирование полет)?"
"@Rui Manuel Cravo Marques, I agree that motors marked "suitable for a 1 kg plane" are not suitable for 1/4 of a 4kg quad. A 1kg plane requires a lot less than 1kg of thrust to maintain altitude or climb at a reasonable angle, so the motor probably…"
