Maybe you're a fantastic pilot who never experiments with software. I can say with personal experience that a single crash can cost over $100; not knowing exactly why the crash happened can be painful, at least for some folks. Most other options out there that provide a XBee socket and microSD card cost more than $129, in case you didn't know. Feel free to rag on us for trying to enter a lower-cost option into the market.

 I went for my first twilight FPV flight on Friday night trying timelapse photos with the gopro. I'm about to pull the trigger on a brushless gimbal so hopefully I should be able to get some nice smooth video soon.

I just got a new motor and the smallpartscnc bixler 2 mount so I can run a 9x6e. Now to wait for the rest of the parts I need to arrive from the international hobbyking warehouse.

I swear customs takes boxes and stacks them up into numbers of piles as high as they can. Then once a pile collapses they decide to examine those boxes and send them through. I've had one sit in there for 20 days.

I've had one sit in there for 20 days. I've watched US Customs check inbound air freight boxes with a four foot steel rod. Jam it through one side, make sure it comes out the other, and check to see if it has cocaine on the end.  I'm sure they treat delicate electronics and such with a great deal more care. No, they probably don't.

Has anyone here played with or heard about PID auto-tuning for quads? Our kickstarter just got fully funded and I was thinking of having that be a stretch goal. I dunno to what extent people would be interested in such a feature. We'd open-source it.

Continuous autotuning would be awesome. Quads seem to behave poorly when moving at high speeds or in ground effect because of the fixed tuning values.

I love this feeling: the feeling you get when you get back from the hobbyshop, or you get a package in the mail, you've got your spare parts and all your toys are fixed. Everything works. Nothing is broken. I wonder how long this will last

I just purchased an Extra 330L ARF kit and am trying to get the basics down. I've flown RTF helicopters before but I'm a bit lost when it comes to pairing motors to planes. The wingspan is 40" so albeit it's not huge, it's quite large and I'd like to ensure that I'll be able to take off or hopefully not stall midflight and crash. I know that lower KVs mean more torque and higher KVs mean more rpms per voltage and higher top speed but don't know which application is best for me; anyone have any tips of pointers of where to look for such tutorials? I've been reading over a few sites which are good for understanding the fundamental terminology and approach but because of the fact that there's so many various applications, I'm still confused as to what the best electronics for me would be. Not looking for a record setter, especially for my initial foray into rc planes, but wouldn't mind something that I can grow into.

Quadcopter flown by PS3 controller, first running via laptop then via Raspberry Pi, all over WiFi: https://www.youtube.com/watch?v=y6YfxidsxGs While we're kickstarting the flight control board and "almost ready to fly" quadcopters, we've open-sourced the code which reads in from the PS3 controller and sends it to the XBee on the quad, in the same format that comes from Spektrum-compatible satellite receivers. (115200 baud serial data—no more decoding PWM!) That link is to our fork of AQ32Plus, which is the STM32F4-only version of the popular AeroQuad software (AQ forum thread). Any pledges will help us contribute to AQ32Plus (all open source). It feels pretty good to get paid to do OSS development but unfortunately not very many people think so and thus I'm probably going to have to switch to a different, funded project. :-/ Maybe techno music on our KS videos was the thing we missed. P.S. The PS3 game controller is surprisingly decent once you get used to it, although the throttle not having detents is a bit annoying. If we do height hold, though, it'll be really nice: keep at neutral to stay at your current height, and push in the direction you want to go otherwise.

This is a GoPro on a FunCub. I have a quad but I haven't started strapping expensive stuff to it yet because the board is kind of glitchy and I want to switch to something more reliable. It was really windy - 20 mph gusts. https://www.youtube.com/watch?v=Dbf41Mpm9yg

Wow, the v911 copter is far better outdoors in the wind than I imagined it would be. Fighting the wind isn't the most fun way to fly, but it can be done. after a couple flights I got to work replacing the weighted fly bar with a paddle fly bar. It took some work, but I got it moving freely enough to get rid of most of the toilet bowl effect. I also manually trimmed the servos, although it seems like I need to trim it further forward, but the servo arm is already screwed in as far as it will go. Its also been ah, fairly crash resistant. No damage so far but I've kept most crashes semi controlled/gentle.

Is there a parts list somewhere if I just want to build a quad copter without researching motor brands and propeller sizes and whatnot? I'd basically like to build something to slap my gopro on and dick around with. My budget is fairly high, but I know better than to, say, buy something for $800 that I could build in an afternoon for $200. I can solder and assemble, but I'd prefer not to spend more than say 8 hours putting it together. Is that realistic?

I ran into a bit of a problem. Was flying the v911 into the kitchen, when it suddenly lost all throttle and dropped from the sky, ejecting the battery in the process. I put the battery back in, but the radio commands where very intermittent and jerky/delayed. This makes it completely unflyable. I thought maybe it was radio interference, and moved elsewhere, but it still had the same issue. I've tried rebinding it several times and it is very hit or miss if it does, and still has the response issues. My best guess, is the little antennae wire was just put on flat across the pad, and not actually through the hole. I'm wondering if it has a bad connection and is severely limiting the reception. Any thoughts?

:-( I'm not blaming you, I'm just lamenting the fact that a log of all the flight info would make troubleshooting your problem immensely easier. Almost nobody seems to do this (and I mean logging things down to PID iTerms) and I just can't understand why. Soooooo many hours are wasted surmising, which could be saved by $20... or less. </rant>

Bit more searching and it sounds like it may be the 16Mhz crystal. It would kinda explain the pulse and short duration work when the signals line up, then stop as it goes out of synch.

It doesn't help that it was a scratchbuild, so I'm still working out the kinks too. I think I'm going to build one of those bungee-ramp launching systems and just be done with it.

Just get a new one all together or craigslist a new controller. If you're flying a thousand dollar quad or airplane, find poo poo to log your flight data. If you're flying a $20 toy grade heli, don't. *I have 2 V911's-- it is the best toy grade heli. Its just not worth crunching numbers over.

Victor posted:You are absolutely correct. Perhaps you will see why I went a little tunnel vision: I've been working 14+ hour days on a quadcopter Kickstarter for almost three weeks straight. The flight board for it is $99 in any sizeable quantity so I think you're an order of a magnitude off. But yes, not worth it for a $20 toy. I sincerely apologize for not realizing that. I get to take a few days off soon; hopefully I can become less of a retard. Yeah I guess if I had to specify when I was doing flight logging, it'd be when I was doing my own quad/plane/heli since you're kinda going into uncharted waters. Sorry for my tunnel vision (and rear end in a top hat-ishness), it was late last night

Speaking of SD cards, how true is it that they all can pause (stop accepting data) for up to 500-600ms, at any time? I found that to be the case with the uSD card I used with OpenLog, which combined with the 2-4K of SRAM on that chip, hugely limited the rate I could dump telemetry into the card. STM32F4's have a lot more memory so that won't be as much of an issue, but they also don't have infinite amounts of memory.

I think that is to do with the speed classification of the card? I had a C4 in my Keychain camera, and that produced a choppy video. Replaced with a C8 or 10 and was much smoother.

Also, it's a tricopter. Seems like a quadcopter might be less complicated? (More parts but no yaw control?)
