"@Essam Your operating altitude is going to depend on the field of view of your selected lens. If you need the camera to capture a single image to cover 120 acres, and your lens has a 38 degree viewing angle, my maths say you'll need to fly at around…"
"From what I've heard and read, both here and on RCGroups, ecalc is notoriously pessimistic when any "custom" settings are used. I use ecalc as a design starting point only. "
"Did you run your design through ecalc.ch? I think you've got a good power system design, although I don't see your specific motor on the site. While ecalc is known to be pessimistic when it comes to its calculations, especially with battery…"
"From a practical standpoint, there's minimal difference between a 10x4.7 and a 10x4.5. According to ecalc, the higher pitch would increase the power per motor by a whopping three watts.
Going the other direction, reducing the pitch from 4.7 inches…"

"You may wish to examine the Roswell Flight Test Crew's setup for their demonstrator hexacopter. A recent "viewer response" Q&A video outlines the expenses involved in that particular project. Short version, if the manufacturer hadn't donated the…"
"Looking through the logfile you provided, I'm seeing ERROR messages for subsystem 5, which is the throttle failsafe. Since you say the problem comes up when you're flying at a high forward speed, I'd start by checking the wiring between the receiver…"
"Randy Mackay has a good YouTube video on the pre-arm checks the APM goes through in ArduCopter 3.0 and later. I'd suggest you view that video, then look at your log files the way Randy did and see if there's something in your configuration that…"
"Marc, if you're completely new to flying quadrotors, I'd strongly suggest you start by learning to fly one of the small ready-to-fly aircraft on the market, e.g. Traxxas QR1 or similar. Multirotors are typically more stable than conventional…"
"The people who are opposed to UAVs, UAS, or drones have some very real and valid complains regarding WEAPONIZED UAVs and UAS. Unfortunately, due to the valiant efforts of the American media to convince the public that those are the only uses for…"
"Most of the American public only knows of UAVs what they hear from mainstream media, and that's largely a matter of hearing about what went "boom" in Afghanistan. Ignorance, however, is NOT bliss."
""Voluntary guidelines" are exactly what both AMA and SUAS have tried to put together. The problem is that first word: voluntary. The evidence, such as it is, points to someone not thinking those guidelines should apply to them. And even AC91-57…"
"AC 91-57 is a guideline, this is true. However, AC 43-13 is ALSO a "guideline"...one that aviation mechanics are required to follow in order to obtain their certificates as aviation mechanics. The FAA can, and does, fine persons who operate outside…"
"This made it to Slashdot, too. Excellent job by the owner/operator of that UAV."
"Presuming you're talking about the RC side of the operation, absolutely...that's how transmitters with multi-model memories function. :-)"
