About Me:
I am a mechanical engineer with a strong background in aerospace design. I love unmanned systems for the level of cutting edge design and technology that goes into them and the amazing, world shaping things that they can do.
Please tell us a bit about your UAV interest
I am looking to learn more about the UAV community, practice and maybe teach about UAV design, and eventually to produce some of my own designs.

"I'm interested in the 3DR version if it's still available, can pay via paypal, shipping to San Diego, 92024. Tried to PM, but we have to be official friends first :)"
"Still doesn't allow for business use, unfortunately"
"Yeah, the PIDs are definitely affected by the "mass distribution" (moment of inertia), as well as by the motors and propellers and ESCs and the control algorithm and on and on. I don't think it hurts to list the PIDs though. Could save some time…"
"I made a mistake about the CoG issue. John is right - the height from the propeller plane to the CoG does not affect the pitch and roll moments, and, since unfixed bodies rotate about their center of gravity, the CoG location does not directly give…"
"Delrin warps a lot when machining deep, wide pockets (relative to the wall thickness). I'd recommend machining it from polycarbonate. Printing it is a good (but more expensive) option as well. I agree that you should try for narrower, faired arms."
"Wow, that is bloody amazing! I may be very out of the loop, but this blew my mind! Thanks for posting! I would love to make a whole textured 3D representation of my town!"
"Guys, I'm all for making the laws clearly defined and calling out the FAA if they are imposing fines where they can't, but you are all over the place and are taking it too far.

"@W. Joe TaylorAfter a little bit of Google, it sounds like the time period is at the judge's discretion, and several lawyers reported that it has taken up to a year, which is really a shame."
"@AeroProject Re: "To state there is no regulation that covers UAVs is false.'Aircraft means a device that is used or intended to be used for flight in the air...'"

"Very impressive performance from such an inexpensive piece. I'm really impressed. Gary makes a good point, but I think it applies a lot more to toys that to proper commercial uses, that are willing to pay a premium for reliability and ease of use,…"
"I appreciate the candid opinions about the good and the bad uses of these; it's tiresome seeing people represent only one side or the other. They are good options in some situations, and not in others, and we should keep that in mind."
"It uses USB 2.0, which only has four pins. As the name suggests, the pinout is standard:
That said, without plugging it into a PC and installing the software and drivers provided by Samsung, you won't easily get video. You'd have to develop your own…"

"@Justin I disagree that "It would be unreasonable to expect an esc to perform the same in [varying conditions]" Perhaps it's not reasonable at the extremes, where a constant full load with no cooling is compared to a gentle cruise in cold, fast air,…"
"I did find it, but, it looks like they keep their pricing very hush hush. It's a terrible way to do business in this day and age of information. I hunted around Google Scholar, as that's usually the best place to start - open graduate thesis often…"
"Hi, I'm new, but I'm a mechanical engineer with an aerospace background. I believe I may be able to help you out.
The L/D max is well approximated by the equation to the left. It's proportional to the square root of the wetted aspect ratio. The…"
