A Yolo Wizard posted:Whatever I brainstormed on cheap and non terrible parts: http://goo.gl/NL2FTl Good list, but a few suggestions: I would change out the flight controller to a RMRC Dodo or something that can take direct voltage, then you won't need a BEC or any sort of step down. Receiver gets proper voltage from the flight controller. Not sure how that VTX is, but I have been using RMRC's cricket VTX's in all my stuff lately, I do direct voltage off the pdb to the VTX and let the VTX power the camera. I haven't used any sort of filters and not having any issues without it. And to echo everyone else, just get a drat Taranis. I have friends locked into JR/Spektrum radios and I just roll my eyes every time they bitch about not having the flexibility to setup switches to do whatever the gently caress they want and they won't swap over. Take the time to learn how to do telemetry with the Taranis and set timers. The only useful thing on an OSD for a race quad is battery voltage anyway and you can save weight and headache by not setting one up. The only advantage of a Spektrum is that you can buy cheap lemon receivers for $10 that do 6 PWM channels. A spektrum receiver that can do CPPM and 3 PWM channels costs like $60, a X4R does sbus (16 channels) and 3 pwm channels and is $25. A X8R can do 8 PWM channels and 16 sbus channels and is $30. Those two are the only receivers I use anymore, and the only use I have found for the X8R is my plane with a vector, flaps, and a pan/tilt, which needed 4 PWM channels. nerox fucked around with this message at 20:00 on Jun 14, 2016 |

I had it listed but, there are cheaper options out there that I think can take direct voltage still (check joshua bardwell's vids). I have two rmrc dodos that I'll be swapping soon since I can't put dronin on there that vtx is fine, and its the cheapest one you'll find. the cricket is just a 799t in a metal case (quanum has an identical one as well). LC filters are always recommended, and you can usually find a spot to fit one in. Annoyingly they are usually designed for 3 or 6s, with the "4s" ones being a little too low voltage wise on the cap. moron izzard fucked around with this message at 22:56 on Jun 14, 2016 |

Oh yeah, I built one of the FliteTest Might Mini-Arrows and got it maidened last weekend. Very easy build and flew well!. I had it built up as a 3S FPV rig, but you could easily turn it into a casual 2S LOS wing.

Yeah, I started printing out this last night, so I can turn it into a 4S monster: http://www.thingiverse.com/thing:1410967 The standard build can only fit 3S lipos. I also have a ton of 4S 1000mAh that will be perfect for this.

Anyone know what sort of longevity those tiny whoop motors have? In my experience, small brushed motors like that only get a couple hours total of run time before they start to crap themselves. Then again I crashed my nano quad (estes proto x nano) alot, which probably caused them to fail a bit earlier. Also what are people paying for the upgraded ones, assuming they are ever in stock?

Yeah, all of the stuff they recommended by name was sold out. I went with stuff from Amazon/EBay that had good reviews. I didn't know the little nano motors and batteries had such a short life. That actually explains a lot, though.

sigseven posted:It sounds like you're trying to use a self-leveling mode (Angle or Horizon). Did you calibrate the accelerometer on a level surface? Also make sure you didn't accidentally change the trims on your transmitter. Note that even with self-leveling, it doesn't have the gps to hold the position, so when acted upon by wind and other forces, without some correction it will continue moving. What is self-leveling mode? I calibrated it on as level a surface as i can get here (i don't have a circular level, only a ruler, so i need to rotate it 90 degrees to get both axis) I am fine with it drifting a bit up and down or not being perfectly perfectly still, but i was expecting it to not move in any compass direction when the only input it receives is throttle?

Tiny Whoop trip report: Fun to fly inside the house, tiny whoop and dog chase each other around. I would go outside and try it, but its raining. sigseven posted:Tiny Whoops are so hot right now that it's probably going to be a crap shoot for a while. ReadyMade RC started carrying them and the MMW motors, but they're out of stock too. I was at the Southeastern FPV event on Satuday, a vendor had about 5 inductrixes and 5 Hyperion branded cam/vtx's and they sold them all between 8:30am and 9:30am. nerox fucked around with this message at 19:23 on Jun 15, 2016 |

Or is it drifting in multiple/different directions?

It would be better to use something like a möbius or other low profile camera, but I'd start with at least a 37" (check their xl models with more room for fpv gear.) there's also some stuff from sweepwings, or maybe the tbs wing with built in GoPro mount The videos section and threads on rcgroups should give you a better idea what cth wings people have successfully stuck go pros on

A Yolo Wizard posted:download fpv free rider and watch joshua bardwells tutorial (multi part) I'm actually pleasantly surprised that FPVFreerider has a linux version. That combined with the PPM2USB lets me run it on my laptop, which is convenient for me. Next step is to see if the signal coming out of a RX module would be the same as the one coming from that Turnigy 9X output jack, and make it into a wireless PC sim controller. I know they are both PPM, but maybe not sure if there are some difference like voltage levels or pulse/frame duration.

There are a lot of possibilities, but I'd start with re-calibrating the accelerometer. You could try it in a different orientation on the surface and see if that changes the drift direction to rule that factor out. Make sure your transmitter is sending 1500 at the neutral position using the Receiver tab in cleanflight. If not, use your transmitter's options/subtrims to center it. Is the battery sitting at the back of the quad? If a heavy battery is pushing the center of gravity to the back, that could also cause this behavior. I think you could overcome it by increasing the pitch I-gain, but it'd really be better to move the battery forward so the CG is balanced around the flight controller. It might just be covering up the underlying issue, but you should be able to use the trim controls on your transmitter to counteract the drift. Slowly increase the pitch trim until it hovers. The trim controls are the little two way switches to the sides of the sticks.

I'm nearly there on finishing building my quad, just a few questions linking everything up with the flight controller. I'm using the Skyline 32 from Emax and I'm getting most of my understanding from this website. and assorted manuals.  The cable on the left, brown & red go to the pcb to power it and then the next four cables connect to my motors. I'm guessing I just somehow remove the final 2 as they are for when you have more motors? Then the cable at the bottom for the Flight controller, furthest right yellow cable goes to the LED strip and then how do I link with the first 3 on the left to my FrSKY x8r module? Forgive me if this is obvious but I havn't found a website detailed enough for me and all the build videos I watch seem to just gloss of it...

SPM posted:I'm nearly there on finishing building my quad, just a few questions linking everything up with the flight controller. It's pretty much all explained from your link:  You need to match ground to ground, vdc to vdc and signal to signal on the RX. Colours are already the same (black/brown being ground) You also need to set up the X8R for PPM.

Cppm is not an option for the x8r from my googling. You'll need to id the uart pins and probably follow a similar guide to connecting it to a naze32 Edit: the moral of the story is to stop buying Chinese naze32 clones and to start buying Chinese f3 board clones moron izzard fucked around with this message at 21:21 on Jun 16, 2016 |

I got my Hobbyking order in today for a bunch of my quad parts. Still waiting on a couple other orders from other retailers, but plenty of things to play around with for now. I was trying out my motors and ESCs, with one of these little super cheap servo testers.  When I tested it, I could turn the knob and the motor spun up, and ran fairly smoothly. But I noticed that the top end of the knob, 90-100% I hear and feel(by holding the motor base) some roughness going on. Like its losing track of the motor position, and twitching the coils in the wrong direction briefly during the rotation. Any idea why it would do that? Poor signal from that servo tester? Or maybe some quirk of the ESC firmware? Its an afro 12A.

Motor commutation is done in software in ESCs. How much commutations it can do per minute is therefore limited by the performance of the microcontroller. You're hitting the limit of the ESC. That said, without load (a prop) the motors spin way way faster, so I wouldn't sweat it.

I'm a newbie, but would like to do some aerial photography in the San Juan islands (Washington/Canada border). It seems like all DIY talk about AP has dried up as the Phantom has taken over, but I'd prefer something more disposable, or at least moddable to float. Any ideas?

I'm thinking about picking up a Tx/Rx and getting back into RC. I used Spektrum stuff and flew 3D planes, but this time around I'd like to get into quads (and resurrect my one remaining 3DHS plane). It looks like the FrSky Taranis is the pretty well accepted way to go? http://www.hobbyking.com/hobbyking/...em_Mode_2_.html It seems like when I got out of the RC hobby, everything suddenly became really cheap and great. I'm really not used to this module style Tx thing, and it's confusing as hell. Also as far as I can tell, I can get that Rx and a OrangeRX DSMX/DSM2 module and bind to an Inductrix, which I know nothing about but judging by this page is the New Hot poo poo.

Does this thread also discuss off-the-shelf drones as well as home-built? I want to buy one for recording video of local sporting events but I have zero interest in building one myself. And the Amazon reviews for drones have a lot of posts that look suspiciously like company shills.

Budget wise, I saw some in the $1300-$1500 range on Amazon and would be fine spending that as long as I'm getting quality for the money. Flying environment is outdoors, mostly over fields with trees on the edges. The events are LARP combat games.
