3DR is stating that they have tested KDE ESCs with Pixhawk, and the wiring done in the advised manner, and the system works fine. No problems with calibration, and no problems with sync.

I've not seen many people happy with that gimbal. There's a huge thread on *** with a lot of pissed off people. That being said, I use the AlexMos 32-bit system on different mechanics, and yet, it can be maddening. You think you have it in the shop, go outside, and it doesn't work anymore.

Thanks. I try to be accurate. So Patrick's response confirms a few things. Still odd that we saw a few reports of the KDE ESC's kinda sorta working. There must be another piece to the puzzle still. Patrick, are your ground planes separated? Is there any continuity between the signal side...

Glider, I would think that simply using a UBEC would accomplish exactly the same thing. This is how my helis are done, and I have no problem with them. But I do not understand what's happening with the KDE ESC's. I thought the symptom was that they kinda sorta worked with Pixhawk, but didn't...

Hello, Do you have previous MR experience? I'm just curious about what you mean by the motors are screaming. What you're describing is very odd. There should not be any problem like what you are describing unless you have set up your system improperly. Which flight mode are you testing in? Rob

Also, in your diagram, you are showing a dedicated 2S Lipo for avionics. Is this something you're recommending? Just to eliminate motor noise? Note that, while this is generally good practice and I do it on my larger helis, you do have to be careful. The regulator in the Power Module has a...

Hello Patrick: "special thanks to Rob", is that me? I'm really curious about this. I had wondered if the problem was to do with poor ground connectivity in the system, as I've seen quite a lot of noise on the ground line when using the Pixhawk with servos. But Lorenz, who designed the...

For an extra degree of interference protection, use one VTx with a Left-Hand Circular Polarized antenna, and then the other with a Right Hand CP antenna. I also thought that dual VTx setup would not work, but turns out it's totally not a big deal. Though, we're only talking short range. Not...

I recently wrote this for somebody else, but might as well cut and paste it here: Here is the list of items you'd need to purchase. Most of this will come in a package from 3DR on this page: https://store.3drobotics.com/<wbr>products/3dr-pixhawk - Pixhawk - No PPM Encoder - No Airspeed...

You said "versatile". There's really only one choice then. Pixhawk/Arducopter does just about anything that you could want.

The Sony QX10 actually looks like a really nice option. But again, suffers from no remote trigger. And the new Sony QX1 is even better but... no remote trigger. Come on Sony!

Yes, I mean... this is why I've been saying, I don't understand how it could *not* be used for pro filming. It flies very well, and has done so for some time. A big part of the reason it flies so well, is because we care about sport/acrobatic performance as much as we do auto flight. There's...

Yes, please change it to "Arducopter Developers are Awesome". ;) But seriously, I think interaction like this is what makes Arducopter/Pixhawk the best system on the market.

With the DJI controller it's not a great test case, however, since they appear to be artificially limiting the frame size that you can use with the system by constraining your gain settings. Unless you are free to crank up the gains to whatever you need, then it's not an indication that you are...

So what happened, you couldn't get it stable? I was flying my 30 minute quad with 15" props with no payload yesterday and... it sure isn't sporty. Lots of power, but the rate control is just sloppy. Wind really knocks it around.

I'd like to see it done. Well, let's see what it would theoretically take, to start with. What would you guestimate for the weight of a DLSR, and gimbal? I was tossing around some numbers about what it would take to lift a 10kg payload for 15 minutes. It would take so much battery, that it...

No, I don't think the numbers work out that way. I believe motor torque goes up as the square of motor size, but propeller inertia goes up with the 4th power of length.

From what I've seen, mapping long distances with heavy payloads, multirotors are a dead-end. I would love to be proven wrong. But I have not seen it done yet. 200 gram camera for 15 minutes, yes. And maybe a bit more, yes. But you're not going to *fly* a DSLR for 30 minutes on a multirotor.

I agree Chuck. But there's a few issues here. The reason this tends to be done, is for flight time. Everybody wants to fly a DSLR for 30 minutes. Larger rotors is the only way to do that. However, it begs the question "why do you need to fly for 30 minute non-stop?" There aren't really any...

I think what you're talking about has a lot less to do with the actual arrangement of the motors and arms, and a lot more to do with larger machines with large props being less responsive than small machines with small props. There was always a theoretical point where the inertia of the props...
