32MB OF ESRAM posted:geez, that is very stable. the first few seconds look like tripod footage. Yeah, I was actually flying it w/ the gimbal locked forward (until I pitched it down) so the pan is from me turning the drone rather than just the camera. I'm sure once I get more comfortable with it I'll be able to pan smoother but I'm also pretty sure there are some settings to dampen the follow speed of the camera. I'm waiting on my second controller to arrive so hopefully when that comes the video pans handled by a second operator will be smoother. Here's a pano I just stitched together and touched up a bit... it's ridiculous how easy this was to get, I mean I have a good amount of photo editing experience but this was having only flown the Inspire like a half dozen times and only spending about 15 minutes in Photoshop (photomerge) and Lightroom combined.

Well, I now have everything ot build my "last" quadcopter. It's the fiberglass QFO frame. I have some DYS 1806 motors, some 12amp speed controls, a flip32+, a CPPM capable receiver, and a crap-ton of LEDs. The only other thing I might want is a GPS. We'll call this one "the cheap mans phantom".DreadLlama posted:I for one would like to learn a lot about heavyweight, long-endurance drones that are mostly battery that you could set to patrol over a fixed route and take a downward pointing photograph over fixed gps co-ordinates, and compare that to its previously taken photo, and send you an alarm if there are any significant differences. Yes, people have made gas engine powered multi-copters. Doing the gas motor -> generator -> speed control -> electric motor thing is dumb though. The good ones use shafts and belts, and collective pitch instead of rpm controls. For all sorts of reasons, it's a better plan. This has flown with a gas engine: http://curtisyoungblood.com/V2/products/quadcopters/stingray-500

The main advantage multicopers have over regular helis is that they are simple to build and fix. If you wanted an endurance platform, helis are more efficient anyway.

It's more what it can do vs a heli. Having 4 rotors changes what it's good at: https://www.youtube.com/watch?v=Scj8_XEEL1A (plus it survives diving into the weeds way better than a big 500 heli)

quote:The vibration was sufficient to cause a structural failure as the starboard rear helicopter broke off its mounting, its rotors cutting into the envelope. The unbalanced lift then made the vibrations worse and all of the other helicopters broke free. Well, that ended poorly. My crashes don't seem so bad now!

Ok I was planning to buy an RTF kit off amazon but now I must build this Polish flying contraption machine. I will refrain from calling it a Zeppelin out of respect. Is thermite still the best choice for painting? What about hydrofluoric acid? Have we decided whether rigid capsules of soft-vacuum were better than gasbags for compartmentation issues?

on the pc version, you can set altitudes for each waypoint. I'd assume its the same for the ios / android versions. Also I manually put mine above tree / wire height before starting the mission.

Radbot posted:Has anyone tried the DJI Ground Station phone app yet? How can you set what altitude the bird needs to get to before taking off on a mission? Waypoint #1 always needs to be directly above your home point at the altitude that you want your 'first' waypoint to be. Otherwise it will fly a gradual ascent to your first position and run into that one tree. That said I never have used ground station. I'd just as soon fly it myself.

Whatever you do, just remember to pre-puncture your lipos. Maybe assign a servo to an aux channel that can slice into the cells while you're midair?

Welp, turns out my (admittedly cheap) Syma X5c Does not have reverse polarity protection. I found out because i bought a battery that physically fit and had the same connector, but the leads were reversed. luckily a brand new control board costs the mad price of 10 bucks :v (expected delivery: march 10th, gently caress...)

Seeing all the curious and wary sea life was pretty cool, and he does recover the thing. Watching the video though it looks like he was *trying* to stall (which I don't think for a moment he actually was, he was just disoriented.) I did something similar my first real oh poo poo I'm lost crash.

Yeah, he was pretty clearly directly in line with the sun, made worse by it glaring off the ocean. The plane was probably an un-orientable black blob at that point.

Yeah, I was wondering why the glare was a problem when he was facing away from the sun... then I realized he likely wasn't flying FPV. I suspect my OSD saved me from losing my plane the first time I got it up FPV. Home direction arrow came in handy until I began to recognize the area from above.

"becoming dated" It's not the choice of people who fly fast. it's not the choice of people who want to fly aerial video or photography. It's also big and relatively heavy. It's only real advantage is not needing a PC to re-program it. It is not the best flight controller. "multiwii" based flight controllers are the common choice for a lot of aircraft now. Depending on weatehr it's a atmega or stm32 based.. it may use the same processor and gyro as a KK2, but you'll have the option of getting barometer, magnetic, and GPS sensors on top of the "well I know which way down is." sensors.

I just want to make a little FPV platform. I see people using some sort of shaft extender instead of a 2nd set of motors to create an 8 prop quad. Obviously this is more work for the engines and ESC but does it also provide more lift, or stability?

No idea, it was just a picture someone sent me. Hopefully just a crash and nothing any worse than that. God drat you Hobby King they just started a 10-30% off sale, the SK450 I had been eyeing (RTF but I'll use my own radio) is like $128 - even cheaper than the PNF version. Can I mentally justify another $50-70 shipping charge on a separate order? Probably not.

And your efficiency goes down. Most prop losses are at the tips. The more tips you have, the more you're "giving up" to those losses.

The Super-X and the Turnigy are completely different sizes. The turnigy one is 250 class, the Super-X is 125 class. The stability problems that guy is having are most likely related him using a KK v3 board, instead of a KK2 board. The KK (original series) boards have gyros only, no accelerometers, so it can't determine "up" Nerobro fucked around with this message at 08:07 on Feb 3, 2015 |
