    Pixhawk Feedback?

    Took a couple new birds out to dial in this evening along with my X-8 with Pixhawk. One of the new ones is a 700mm, long duration camera bird using Pixhawk, the other is, or was, a quad configuration using a Discovery frame, s800 arms, 600kV motors and A2. The Pixhawk bird took off using...

    Another A2 Failure

    The bird was a test bed so the crash wasn't too expensive. Discovery frame, s800 arms for quad configuration, 600kV motors, and of course the never to be forgotten A2. Losing the home built Go Pro gimbal up front was a bit of a disappointment. Flew great in manual and Atti but tried a POI...

    Pixhawk Feedback?

    Washington/Oregon border. Bulk of the equipment is in Texas. San Diego or Berkeley and and 3dR's offices would be a lot shorter drive.

    Pixhawk Feedback?

    I'm a bit too far north of you to give mine a try. I'm neither engineer nor nerd so I have to take things slow and work at it a small portion at a time until I gain a solid grasp of what I'm doing. APM 2.6 was my first foray with the open source stuff and candidly I didn't have to do anything...

    Nice thing about an open source, if you're good with code (I'm not) you can look and make changes as you deem necessary. I work with a high end closed source AP, which in and of itself is not a bad thing because the source accepts responsibility for errors/deficiencies and makes fast...

    Another brilliant enthuasist

    I do like how the Ozzies have encouraged interest and activity of the public in the design of sUAS systems. Providing the venue for them to standardize their mission criteria while exploring open design formats really pushes the creativity levels and improves reliability and efficiency...

    Maiden flight of an Iris

    Putting a Pixhawk or APM in Loiter mode is like telling it to "wait here. I'll be back in a few minutes". I would have been truly disappointed if the user didn't do great;) 3d Robotics does an extremely good software set up with their RTF birds. Some of the accessories like FPV, monitors and...

    How beat up is too much?

    Most carbon props start out as top and bottom shells that are joined together with fiber filled resin. When you take off the tips you generally take the tip back to where you passed the point where the two shells were bonded and all that's left is the glue that was holding them together. The...

    Will AirDog put us out of business? Drone will follow you anywhere...

    Found out how that works with UAV's. Don't upload a lost comm return route unless you first verify there's not a mountain in the middle higher than the flight plan......

    Coaxial Vs Flat

    It gets more complicated. An X8 is 5% to 6% more efficient than a flat 8 all else being equal. A very innovative aerospace company just ran a series of tests on that theory after it was presented to them and it proved factual. Doesn't sound like much but on a tethered 150lb MR it mattered...

    Pixhawk Feedback?

    What GPS are you using? The latest Ublox with compass is extremely accurate. Their older GPS was adequate and held altitude quite well but was slow to acquire at times. Ublox took care of that issue. I wonder, had you performed all the accelerometer calibrations? Was it possible the auto...

    Pixhawk Feedback?

    Plus 1 to the above. It's a very solid flight controller with extreme capability but one has to take some time to read through all the WIKI info and learn how it works. Outrageous functionality and there are some super easy to use flight trimming tools but they are not instinctive. If you...
