"What battery are you using?  Your power module is indicating ~11.5v resting and 10.4v under load.  If this is a 3 cell pack it should be 12.6v when full.  Could it just be running out of power to stabilize itself?"

"Hi Matt, I'm doing a similar setup and am curious if you have any other tips. It flies... okay. It's pretty squirrely and I have the roll/pitch sensitivity and feel turned down almost all of the way. I have not tried AutoTune yet. Yaw is…"

"There is no calibration or signal the pixhawk could send that would burn your escs.  Do you have multiple bec power from escs in parallel?"

matt.koestner replied to Benjamin Meltzer's discussion Removing Rolling Shutter Artifacts
"In my experience this can be solved by damping the vibrations before they make it to the camera.  And it's not only spinning things that can cause the problem but flexible frame parts are just as important if not more so.  I'm…"

matt.koestner replied to Dennison's discussion Please Help: Fly Away. I suspect vibration but need help analyzing telemetry
"Hey sorry for the slow reply but you will need to cut all of the ESC BEC power wires if you will be using an external BEC to supply +5V to the servo rail.  Alternatively use 1 ESC BEC and cut the rest of them."

"Hah no worries!  I'm at work, so plenty of time to do other stuff :-) Once you get it tuned you will be amazed at how much wind it will handle.  I have almost the same build and regularly fly it in 20-30 MPH winds, snow storms,…"

matt.koestner replied to Dennison's discussion Please Help: Fly Away. I suspect vibration but need help analyzing telemetry
"Awesome!  If you open log ending in 18-26 look around timestamp 67441 you can see when battery voltage falls below ~10.7V, RTL engages.  Your battery failsafe is set to 10.7V which is OK, maybe a bit conservative but it really depends on…"

matt.koestner replied to Dennison's discussion Please Help: Fly Away. I suspect vibration but need help analyzing telemetry
"Personally, I flip the mode switch to cancel rtl. Say if you are in position hold, then RTL kicks in, just flip to alt hold and back to pos hold. The failsafe will keep beeping and flashing yellow, but you'll be able to control it normally…"

matt.koestner replied to Dennison's discussion Please Help: Fly Away. I suspect vibration but need help analyzing telemetry
"I'm on mobile now so can't look at the log, but the yellow flashing indicates Pixhawk is in failsafe.  The climbing is because then RTL is invoked, the copter will climb to a pre set altitude (RTL_ALT).  All you need to do is…"

matt.koestner replied to Ben's discussion Please could someone help analyse this Autotune/Pixhawk crash? in the group PIXHAWK
"Well it's not really a coincidence.  Autotune demands large and fast attitude changes which demand rapid RPM changes from the power train.  Any ESC, motor, or battery problems usually show up during auto tune.  Look at it this…"

3DR Pixhawk- powered DJI S1000

Posted on May 20, 2015 at 9:27am 33 Comments



For the past several months we have been working closely with an infrastructure inspection firm to develop a multirotor system for them.  There were many goals, but COTS parts and cost were major drivers.  We decided to use a DJI S1000 frame but selected the 3DR…

Hi, Could you please send me your patameters (pid) for the s1000 and pixhawk? I'm getting out crazy. Thank you a lot.

Hi Matt, I am a student at CSUCI in California and I'm having difficulties tuning a DJI S1000 setup using the Pixhawk. I noticed that you have had much success using this setup, and I was curious if you could answer a couple of tuning questions and help us out a little bit. If you would be able to take the time, I would be extremely grateful.
My email is: chase.m.tillman@gmail.com
Thank you.
