moron izzard posted:wanted to see how small of an ardupilot capable wing I could build. omnibus f4 nano, 7a blheli32 ESC (turnigy, which im pretty sure are rebadging of the racerstar tattoo series), that motor, among other things After seeing it come through the FPV reviewer sites, I kinda wanted that new ZOHD Talon GT "Rebel", that boxy looking gently caress. It's sort of just a giant crate you can load up with gear and send into the air. What I don't have is enough influence to get one for free, and geez $200? Last time I had 200 spare dollars was before I started this hobby. Instead I made my own out of parts I had on hand, a sheet of dollar tree foam, and a rigid insulation project panel. Total new parts cost, under $10.

So I built my quad and have been loving around with it mostly in horizon mode. I've only hosed up 1 set of props and chipped the frame a little. I'm still poo poo at it, however, so I had some questions: -How do I properly attach the battery? I get the feeling that part of the drift the quad does when only throttle is applied stems from the quad not being balanced, which is for the most part due to the battery shifting in flight and me probably not attaching it centered in the first place. -Is it actually easy at all to hover roughly at the same height? I'm always either bouncing from temporary ground effect lift or taking off immediately. -How the gently caress do people fly these things at full power I've set my max throttle to 25% and I'm terrified

If the thing wobbles and leans on throttle application it could be from FC set up or props, these things are fairly resistant to imbalance. Maybe check your antigravity settings if that’s still a thing and you are using beta flight. Leandros posted:-Is it actually easy at all to hover roughly at the same height?

Everything else is a matter of practice and getting the muscle memory down. That said, a larger camera angle helps make speed less intimidating, since you'll have better visibility while speeding.

Speaking of sim, it's been probably two years since I touched my drones and I want to get my flight legs back under me before I take my gizmos out into the real world. Two questions: - Would OpenTX on a turnigy 9x prevent me from using the trainer port? I honestly don't know y/n - Has anyone hooked up a Turnigy 9x to a Mac for DRL? I ordered this which may or may not work with the 9X; if not I'm only out ten bucks.

Martytoof posted:Speaking of sim, it's been probably two years since I touched my drones and I want to get my flight legs back under me before I take my gizmos out into the real world. Two questions: 1. The t9x has an issue where if you have a radio module plugged in (even if it's the stock module that's hardwired to the antenna), no signal will come out of the trainer port. You can either unplug the radio module, or see if you can change the protocol in your software to "PPMSIM" (not PPM). 2. Haven't had experience using one of those before. A long time ago, I found some software solution that involved me plugging my radio's trainer port to my computer's microphone port, which then converted that signal into inputs on a virtual gamepad I could use in sims. That dongle just seems like a hardware version of what I was using, so in theory it should work I guess?

I'm getting back into this after not flying for maybe 10 years. I need a new radio and I'm completely out of the loop on modern radios and 2.4 GHz stuff. I would like to do both fixed-wing stuff and quads at some point. The suggestion I got was the FrSky Taranis X9D Plus. I ordered one today, it was like $240 with GetFPV's case-and-receiver combo. I should have asked this beforehand but they've been out of stock for months and I jumped before thinking, am I gonna horribly regret not getting something else instead? It's probably not too late to cancel the order or return it...

I ended up cancelling and getting the SE for a couple bucks more (and no hard-case but oh well). The better sticks, charger, and detachable antenna sold it. I got a little parkflyer at Toledo, it has an ESC but only two plugs, one is obviously battery and one is throttle PWM. How does the receiver get powered in this situation? Does the ESC backfeed the receiver using the throttle connection when I plug it in? The receiver I got was the RX4R if it makes a difference.

On your ESC or servos you have three wires: ground (black or brown), power (red or orange), signal (white or yellow). The ESC provides 5V to the receiver and servos by way of the power wire. It’s called a BEC (batter eliminator circuit).

Built a tyro79 today as my first fpv quad. Motor check was good, no puff of smoke, so I'm pretty happy. I got a kit with the good camera cable but only 5 nylon standoffs (of 8) so I can't finish off the build. Has anybody else built one of these and bound it to a flysky fs-i6? Should I be using PPM or SBUS / IBUS? PPM works but I'm missing 4 aux channels. SBUS wasn't working but now I realize it was probably a failsafe error and not a compatibility error.

Judge Schnoopy posted:Built a tyro79 today as my first fpv quad. Motor check was good, no puff of smoke, so I'm pretty happy. iirc Flysky gear defaults to iBus and the last time I used any of their RX's they were buggy as hell and even if you pressed the button to put them in sbus mode they'd reset every time you cut power so you had to do it every time. definitely use ibus if you can, it's better than PPM.

But the real question was "will my Rx on ibus work with my fc on sbus" Sounds like I need to keep digging until it works to avoid ppm

Judge Schnoopy posted:But the real question was "will my Rx on ibus work with my fc on sbus" No, it won't right off the bat. You need to go into the configuration tab of betaflight and change PPM to iBus. It will be in the list just like sBus and a bunch of other protocols.

Yeah did everything I could, ibus just would not work. Even tried a different Rx and got nothing with the ibus settings / solder. It's possible I just didn't have a good enough solder to bridge it but it looked ok to me. Maiden flight of the tyro79 (using ppm) was successful so at least the rest of it was built correctly.

Looks like someone is importing the Jumper T16 where I am living and certifying them with the radio transmission authority. I have a few cheap planes I was misled were FHSS compatible that I was considering swapping out components to get them to work, but I'm kinda lazy. Is the T16 good enough to just get that instead?

CapnBry posted:Something to note, SBUS is inverted and IBUS isn't, so don't connect it to an SBUS input put that has a hardware inverter on it or it won't work. When connecting things over IBUS, I usually combine the IBUS and telemetry into a single pin and connect it to the TX pin of the UART I am going to use. The TX pin associated with SBUS usually does not have the inverter so it solves both problems. Downside: you need a diode and resistor to combine the wires using this pseudo-schematic. I also have to change things like 5 times between "Ports" and "Protocol" in the iNAV's configurator before I can get it to stick properly for some reason. Jeez, I'm glad I gave up and settled with ppm. Maybe someday I'll upgrade to a big boy frsky x7, use real sbus, and move on from crazy hacks.

Judge Schnoopy posted:Jeez, I'm glad I gave up and settled with ppm. Lol yeah. You don't need to rig up some capacitors and resistors into a cludge though maybe, post a picture of your flight controller, there is probaly another pad you can solder your signal wire to which will get iBus working right I completely forgot about the inverted/uninverted nonsense. That is almost certainly what you're running into if you're soldering your RX signal wire to a pad labelled "sbus" Honestly though if your thingy is working and responding to your controller just go fly it and have fun. You can gently caress around forever making a """"perfect"""" setup that never leaves your bench

Looking at the FC for the tyro 79, I think you might just need to solder the jumper for PPM (so it disables the inverter circuit) and then you should be able to use whatever UART the SBUS connector goes to. Alternatively, you could just wire the iBus signal into any other available UART and select it from the Ports tab. And then remember to select iBus for the protocol on whatever port you wind up using.

Are you talking about those XK fixed wing models like the A800 that say "S-FHSS" on the transmitter, but actually use WLToys protocol instead? Those should work just fine with any Jumper radio or STM32 multiprotocol module (e.g. iRangeX IRX4). Based on tutorials, it looks like KN -> WLToys is the protocol/subprotocol you want for this if using OpenTX/JumperTX.

Yeah. I got the DHC-2, and the extra300, both used S-FHSS and I was happy with them. So I got that glider (sans transmitter) because the website said it was also compatible, when it was not. Also got the 3 channel predator, and that seems to be something different than the glider's WLToys receiver board (or I failed at binding it). E: I also have that baseline Spektrum, but it is a pain to tweak profiles. Bought the old phone cable for it, but that was deprecated. Bought the USB cable, and that can only do so much, updating the transmitter firmware makes the USB cable stop working and requires you to get the new Bluetooth adapter to use with a smartphone. So I guess the Jumper would help me out with that, too. Corky Romanovsky fucked around with this message at 03:56 on Jun 19, 2019 |

When I bridge the ppm pad and select ibus, the receiver tab only shows 4 channels and none of them react to the transmitter. If I select ppm and reboot I get 8 channels that all work. Test flight this morning was successful so I'm happy with ppm for now.

Judge Schnoopy posted:Jeez, I'm glad I gave up and settled with ppm. When I need a micro receiver, I go with a Flit10+ which does FlySky IBUS and includes the pieces needed to run telemetry and the receiver on the same wire and is about $12. FrSky has the nice advantage that any data can be sent back and forth from opentx / Taranis, which allows you to change flight controller settings from your transmitter, but you pay twice as much for the luxury, the protocol has a ton of data drops, and the RXSR I have is EMF noisy as hell compared to all my different FlySky receivers.

If I select ppm and reboot I get 8 channels that all work. Granted I am way out of date on BF firmware, but that sounds like a firmware issue more than anything. The jumper should just disable the inverter circuit and shouldn't have any other knock-on effects. Anyway - glad you got it flying.
