John Dennings replied to HighVoltage's discussion Price of industrial drones
"@HighVoltage: imho, Luc and Ausdroid make very good points. Given your response (you requirements, location, need for possibility of IR, possible map work etc ...) a Phantom won't cut  it, just not good enough  after sales support and…"

John Dennings commented on Sascha Helle's blog post New hexa- / octocopter carbon monocoque frames
"Two achilles heels in monocoques (and yes we do sell one, so we do know): Thermal build up and radio absorption.
Yeah, I could see how what looks like the non CF top would be ok for GPS, but for RC, VTx and telemetry, antennas would somehow need to…"

"Eye watering ... And the detachable  arms are a major plus ...
Would be nice if you could provide English subtitles  in your youtube videos ...   ;) and more details on the arms/center plate electrical connections."

"Problem  is, from having looked into that, no one can be sure. DJI launched Geo as optional beta on p3, word from DJI VP of policy Brendan S.  is it will be a firmware update on p4.  But it's unclear how the final authorization will look like. …"

John Dennings replied to HighVoltage's discussion Price of industrial drones
"Looks like  copters with plastic arms and plastic landing gear. Even if these arms and landing gear  are an order of magnitude stiffer that the $10 flimsy ones available at Hobby King, calling those drones  "the best multirotor by far",  or stating…"

John Dennings commented on Andrew Tridgell's blog post Building, flying and not crashing a large OctaQuadPlane
"Very nice. Looks like moving from X4 to X8 was all win. Do you now see X8 configurations for this type of heavy plane  as your default, preferred choice? Also are the motors powerful enough that you could loose one and still be able to do some sort…"

John Dennings replied to HighVoltage's discussion Price of industrial drones
"Good points worth considering. Ease of deployment (out of a backpack, done), inexpensive, small and light,  dead simple to operate, easier to get closer to inspected item (one way to make up for less camera resolution), those are important…"

John Dennings replied to Darius Jack's discussion Who is legally accountable in case of drone crash reported to FAA ? in ArduCopter User Group
"Reposting this pic from fsnoop just because:

-  I can
-  It cracked me up
- It's even funnier than  "Pixhawk developers are legally accountable for bugs, flaws in code, algorithmics, avionics data processing", no small feat!
-  It sums it up"

John Dennings replied to Alireza Manzoori's discussion Uncontrolled Climbing (& CTUN.DAlt increase) in AUTO Mode, Keeps Climbing Even After Switching to LAND!
""Stabilize, AltHold, and Acro don't use GPS at all"
They do.
(Although it's true you can fly without a GPS attached.)

John Dennings commented on Euan Ramsay's blog post Super cheap autonomous cargo "drone".
"Fun stuff and quite good performance  given "recycled parts" ...
What did you mean by "telemetry useless beyond 40ft btw"?"

"Lol, sure Gary ... HK link and specs on those 12S coax motors, please?
Best bet from the looks is probably custom manufactured and unavailable KDE, have yet to find them but maybe I haven't looked hard enough ... Know of any other "vendors" for…"

John Dennings replied to HighVoltage's discussion Price of industrial drones
"I don't have one (alta) so I can't really say. The proprietary FC bothers me some, but then I am partial to open source where code is there for everyone to inspect, issues very quickly identified, openly discussed, and fixed. So more trustable than…"
