"It doesn't appear you had a brown out or GPS glitch. What is odd is that just after you took of (in Stabilize Mode), all your RCIN values ceased changing and remained at fixed values until your aircraft crashed. I would recommend you take a…"

"Not had a look at the log but you seem to have taken off very close to a cellphone tower.  I've had a few flyaways when I flew near (50 - 100m) from a cell tower.  Never happened since I moved to a different location. "

"Good evening. I have had a good day. Lots of tuning. Seems now (no wind yet) very stable in all modes except Loiter. I am going to put together a page with logs, pictures etc in the next few days. I will make sure it gets linked here."

"Yes I think it is over powered - thanks I will try that. Not sure about sync - logs are up on my forum post. I added 4 kg (total of 11.2kg AUW) for a test - 50% throttle only which is good, but still oscillated (less though) - need to play some…"

"Hi Scott, my quad is a 500mm with 950kv motors, 20a esc, running a 2800 3s and FPV gear (no gimbal) flight weight is about 1.2kg, Its a little under powered but holds alt with full pitch or roll. So I guess its in a different ballpark from your…"

Scott Penrose replied to Richard Evans's discussion Getting the PIDS right on a heavy copter
"Hi Daniel. Have you tried it on a heavy lift copter? I tried it and crashed. Not really a fault of Auto Tune, but Auto tune, as per the docs, uses a lot of input, and can cause sync issues on low KV motors. The docs don't actually say not to…"

Daniel Leete replied to Richard Evans's discussion Getting the PIDS right on a heavy copter
"providing your quad is able to fly with the stock PID setting (I had to lower mine abit) and you can switch to alt hold with successful results you can then use autotune which you can setup with a switch on ch7."

Live in Texas, grew up in Florida, I'm also an EDF enthusiast with lots of EDF aircraft and many years of radio control experience.
Please tell us a bit about your UAV interest
I like the feeling of flying like a bird that you get when doing FPV. I guess it is a lot like flying a full scale aircraft. I also love how technical and complex our "birds' are Not for everybody for sure!

Working on endurance options

Posted on January 18, 2014 at 6:30pm 21 Comments

I've been working on getting a better range and endurance. This QAV-540 weighs 5.5 lb's and I just flew it for 18 minutes today. Previously 16 minutes was my record, the change is that I went up one inch in prop size. This is not stripped down for endurance, I want something that will fly a long time…

Some FPV (Cockpit View)

Posted on December 13, 2013 at 3:00pm 4 Comments

!

This is just run of the mill FPV flying, but I enjoy reviewing the fight for more than the visual perspective. Re-living the altitude, the roll and pitch, the rate of ascent and decent, the airspeed during the flight and the battery condition gives me a much fuller context than just viewing the HD video I was recording using my GoPro H3 Black.  Here is simple flyover of ready to be developed…

# note that there is a glimpse of architectural art piece in this video by James Turrell, Skyspace, 2013,  courtesy of Landmarks

I originally solicited other construction company users as to their ideas about using drones in the industry and to heat there experiences. This might not be the right venue for that, instead I got…

Near miss at the beach

Posted on July 23, 2013 at 3:00pm 9 Comments

This weekend I took a couple of boys to the beach (family members) and wanted to get some video of them trying to surf and using a boogie board, (in some very poor surf conditions). Something unexpected happened, through the  low resolution of the goggles, I mistook some other kid and hovered up close.  As he turned to face me, I realized he wasn't the kid I was expecting and instead of a surfboard, he had a surf casting reel. He cast his lure at my…
