Please tell us a bit about your UAV interest
I'm mostly into fixed wings at the moment, but I can see myself getting involve in multirotors going forward. I build all my own airframes, so often an autopilot is just a good way to test out the airframe when LOS or FPV is not suitable.

"For high altitude winds I used the excellent habhub predictor. They have a bunch of other useful tools for high altitude weather balloon launches.

"It was in AUTO mode with a LOITER waypoint specified on the ground. It hadn’t reached the waypoint at that point in the flight, however. From the onboard camera it appeared to be rolling back and forth at about 1hz"
Just dropped a scratch built flying wing from a high altitude weather balloon. Here's quick vid of detaching at altitude.The glider did the right thing and managed to land on it's own at the target landing site, but while looking at the logs I…
My question is fairly simple: how does one decide on the ideal dimensions and ratios for a flying wing given the target cruising speed and payload or other relevant flight characteristics.For a more conventional aircraft, I feel like I have a fairly…
"What I ended up doing is creating a voltage divider and feeding the output of that into the module. This is in parallel (not series!) with the load. You get your voltage sensing capabilities, but no current sensing."
This is a feature request:On the A2 flight controller, there is a two level battery voltage warning. At the first threshold, the status LED turns yellow simply to indicate to the pilot that the voltage is low. At a second threshold, the status LED…
Hi all, I have two rather large Aerial Photography platforms outfitted with Pixhawks. One runs on 6s and the other on 12s. I need to solve the voltage sensing problem.In both cases, I have no interest in sensing current (partially because it would…
The motor 4 output on my friend's Pixhawk seems to be dead. We tested it with multiple ESCs and servos just to be sure.He's setting up a quad, so I was considering taking the sketchy route and flashing X8 to use outputs 5-8, but before we resort to…
"It's interesting you mention this. I saw very similar behavior from my own quad recently. It went fully inverted, and maintained throttle into a tree and then the ground. Just like in your situation, I've never had any issues in any mode other than…"
"I agree, it was irresponsible. I had had successful and much longer mapping missions in the past, so I had some faith in the craft.
When you say, "fall apart," do you mean physically? The frame was actually fine upon recovery, so I don't think…"

No idea what went wrong today (which is why I'm here). I have (had) this awesome Alien 560 quadcopter. As soon as I put it up in the air for the maiden, it flew beautifully. I actually flew an auto mission my very second flight.Anyways, I've put…

"I've attached the telemetry log and KMZ if that helps."
I just put together a (gorgeous) Alien 560 quad last night with a Pixhawk. This morning I decided to fly a mapping mission, and the quad performed very well, but there were a few hiccups in the mission.Even though the entire mission was at 50m, at…
"After updating today, I found a new command in APM Planner which I hadn't seen last time I used it. "Change Alt & Continue." Hopefully that does what I have in mind...?"
Here's a quick mission planning question. So I have a fixed wing aircraft and I'd like to plan a mission in which the aircraft climbs to a target altitude and then performs a servo action. From testing, I found that if I set one waypoint at 30m and…
