Corky Romanovsky posted:I don't see how this makes sense. I could see it pulling a bit more if the quad was in a descent, then quickly throttled up or angled. Essentially negative airspeed. Most things that are thermally limited, current in general, could have a higher max if not at 100% of the time. But yes, if you just set your Radio to only output up to 85% throttle, the flight controller will still have whatever throttle (likely 95%) it's max is set to for balance and rolling/pitching on each motor. It's usually recommended to just have your radio set to send 1000-2000, and set any limits/mid points in the flight controller itself. Had a look at the data sheet, those are good for 12A continuous, and 48A pulsed (300us). I may be reading this wrong, but it says 1.4W power dissipation, with 89C/W above ambient. AKA, that thing'll heat up to 150C on a cool summer day when going full tilt. likely even more if it's insulated by heat shrink. Napkin math, 20A*0.0078ohms=0.156V. 20A*0.156V=3.12W. 3.12W*89+25= 300C when pushing 20 amps. Under ideal conditions. Golluk fucked around with this message at 02:25 on Oct 24, 2018 |

I'm pretty sure this thread is where I heard about dronin which led me to ending up with a seppuku, so I might as well ask here: is 3D something you can set up in dronin? I tried to ask in a 3D freestyle centered discord and just got linked to a faq which was strictly betaflight only. Super helpful that.

Yeah, it can do 3D, there isn't UI for it, though. You need to set the ESCs into 3D mode via BLHeli Configurator and then set the channel deadbands in the UAVO browser to 1 or 2 depending on what direction you want things to spin (tooltip should show up, if you hover the value fields). I think the BLHeli Configurator thing might be optional, because IIRC it sends the appropriate DShot commands when necessary, but don't quote me on that, only time I ever tried 3D was quickly on the bench to test the code when it was a pull request.

Instead of buying an RC gyro doodad I am repurposing a 405-OSD to stabilize a chuck glider with INav. So far it’s going swell, the 2.0 mixer is hilariously better than 1.x Still sucks wasting s2 on single engines but whatever, I got 6 signal pads.

Yes. As long as you mean "burn" by "charge". So, I did a few things in the last week. I bought an Inductrix BL. And some 650mah batteries for it. I like it, but it's a little funny in yaw, and has a gentle pull to the left, constantly. There's not a whole lot to say, other than it does what it's supposed to be. I fixed up my Inductrix. I got the Makerfire A07 F3 board, 19kv motors, and some new JST-PH 2.0 batteries. The Makerfire board, comes with a pigtail that's far to short. I also ordered a couple new cameras, so I could mullet it. I"ll post pictures of the current build. It's a little heavy.. but I get a few minutes of flight time. And 11 batteries. I also visited my local r/c shop. They had a FQ85 frame on the shelf. So.. $7 later I had a new frame for my Doinker. I moves everythign over to it tonight. But I need a battery strap, and to re-solder the motor leads. I think the carbon frame is going to make the thing a better quad, and able to bounce better. ..... What else? I dunno. What are you flying?

ImplicitAssembler posted:that thing floats pretty well for it's size! Like the Bushmaster the approach is to make it as light as possible for its size and power system and pick airfoils, moments, etc for the reduced wing loading. It’s 1.5-2 lbs lighter than similar 70” class planes and needs about 500W less. It flies on the same components as a 60” plane which keeps costs down which is cool. Definitely my favorite design right now!

I mean, I enjoy it (although I barely fly 3D anymore), but it's way easier to learn to fly a miniquad and do 'freestyle'. Helicopters have the same issue...learning curve/cost is simply too steep in comparison to quads.

Thanks! 3D is technically flying the plane below stall speed and using the prop for lift and not just for forward movement. So when it’s really slow with the nose up at 45-90 degrees that’s 3D. But in the last ~5 years it has become a catch all term for all kinds of flying that is done with a 3D plane. Lots of my flying there was precision or extreme aerobatics but most people call it all 3D now. It seemed like it was growing a lot six years ago or so. Then FPV miniquads became a big thing and started to take some of the attention away. And yeah, it’s a much shorter and cheaper journey to the upper end of the quad game than 3D airplanes and helis. However I think some of the novelty of quads is wearing off so I’m wondering if we will see the popularity of other flying disciplines rise again.

Man, I love flying stuff. I got a burr up my butt and finally dove into the PH2.0 thing with my tiny whoop. And... a F3 flight controller. And 19kv motors. And... well there we go, I've gone off the deep end. And printing camera mounts... And a dozen batteries. So my Tiny Whoop grew up. I also found out that there's a local r/c shop. And they specialize in quads. Oh, and they suggested that I come by and fly my stuff "whenever". Friday night, I discovered just how horrific I was at running gates. I can fly my quads around my house, pretty well. But once you get gates involved, wow. It gets a whole lot more tricky. 45 minutes of flight time later though... and I still suck. But at least I know what needs work. I also ordered a few bits from our favorite chinese retailer. I have a eachine revenger 55 mm frame now, and an 80mm race stack type frame. Both are proving to be tricky builds. The 55mm frame is designed to run with this nasty little 15mm stack. And the standard stuff is 16 or 20mm. I picked up a 16mm stack. (FC and ESC... is that a short stack?) And I drilled out the holes in the decks to match. The 15mm stack also has three layers to it... I now only need two, and really just one. Not only is my setup lighter than the factory, it's even going to be smaller. The 80mm I just bought a generic DSM 20mm stack. Which turns out to be 5mm taller than the availble space for the stack. *boggles* I can't imagine what they intended to go there, because it sure wasn't a full stack. Oh well. Pictures will follow.

The thing is I know fuckall about ardu-anything and I was already flying BF 3.x quads. iNav is extremely similar, but with the features I needed. The mixer used to be a legit nightmare (especially if you had fancy things like flap(eron)s) but now it’s pish and I’m not ditching it until it fucks me over.

I make no judgement either way really, iNav is just what I rightfully suspected would be easier for me. It’s probably not great (yet) for stuff like complex missions with interactive payloads but whatevs. Kid throw plane, plane fly gud, kid happy.

is it because 900 * 3 = 2700 and 1.3 * 2 = 2600, and 2600/2700 are close enough to interfere with eachother? Like how a 2.4ghz control link and 1.2ghz video halves its effective range?

bring back old gbs posted:i love NANO GOB V and his big antenna hat Nano Goblins are deceptive in a way that seeing them in a photo doesn't convey just how small they are. A surprisingly good platform though and incredibly efficient. Like 15 minutes of fly time on a 2S 800mAh, and a pair of 18650 3Ah cells will let you pretty much fly the thing to the moon and back again. evil_bunnY posted:It's probably not great (yet) for stuff like complex missions with interactive payloads but whatevs. Kid throw plane, plane fly gud, kid happy.

CapnBry posted:How do you have this set up? I was hoping to scratch build a pair of gliders with my niece and nephew next weekend (already got all the foam cut) and I'm trying to work out how much electronics I need to bring. Just a receiver, flight controller, battery, servos? Any tips to make it braindead simple? When the kid's asleep I can put a prop+nut on it and fly it around (badly). If there's no motor you don't even need to arm the thing, just stick it in autolevel and toss. The first time it saves itself it's like magic. If you have a more demanding airframe that doesn't like to stall you can mount the FC on a wedge so it won't try to pull up. E: If you want to replicate it cheaply, all you realistically need is battery, receiver, fc and one servo, provided you can somehow get some form of elevator trim. You don't need yaw authority on a chuck model anyway. evil_bunnY fucked around with this message at 14:27 on Nov 16, 2018 |

I thought not being multiples of each other I would be fine, but after doing some more reading apparently people have problems with the r9 signal overpowering the video link. Well, I'm already getting farther range than i was with 5.8, and I don't even have a notch filter or anything. I guess I'll see how it goes once I have the FC set up with rth and try going further out

My advice if you’re going to build with kids is to prepare a few credit card tools so they can score/cut the precut foam, and a sanding block for hinges. If you have all the electronics ready it should be fun for everyone.

Maybe? It says "omnibus" for the target, but there's no way to know how well iNav will work (or not work) until you try. Personally I would recommend always sticking with 100% supported hardware for whatever firmware you want to run. Here's the official hardware lists for iNav and Ardupilot.

I have a lowepro quad guard 2. It’s a very nice bag but ends up being tight for my gear: taranis really needs to be squeezed in, making the interior quad storage pocket impossible to use for a 5”. Even if you could you’d still need to remove the GoPro mount, so I usually stick a micro inside and hang my 5” on outside. In that config I carry tx, goggles, charger, tools, several bats, ride along goggles, a 2-3” quad, a 5” quad, and some parts pretty easily.
