Is it really normal for x-frames, though? None of the following make the FC stack part of the structure connecting top and bottom plates: Shendrones (Krieger, Mitsuko, Mako), ImpulseRC (Alien), Black Bolt (XBR), Flynoceros (Orion), Dquad (RefleX), MRM (Scythe, Switchblade), ReadymadeRC (Goby), and the list goes on.

I'm looking at perhaps getting a cheap camera drone to take some aerial photos while hiking in the mountains. Operative keyword is cheap. Would the S3 Quadcopter be good enough?

Based on the lack of listed specifications, I'd guess the camera is 3 megapixels tops. Your phone likely has an 8 megapixel camera or better. So if you imagine taking a picture with your phone and cropping it in half, you'll have a good representation of the quality you can expect on that guy. I'm sure it would be fun to fly though!

sigseven posted:You might also have the min_throttle set too high as well, the default almost always is. Remove the props, and connect to cleanflight while powered on. Use the motors tab to manually control them using the sliders, and find what the lowest value is that still gets them all to consistently spin up. Set the min_throttle to just above that number. So I tweaked the min throttle and that helps a little, however it now flat spins when I hit the throttle. My dinky little Cheerson doesn't do this, so is this a props/motor issue still? Here's a video (excuse the bed shot, only place I can safely land without damage at the moment!) https://www.youtube.com/watch?v=EyFzYMduF68

Connect to betaflight (or whatever software you are using) and look at the RC inputs tab. Make sure the rudder is centered at about 1500 microseconds. You'll need power to the receiver for this, which means battery plugged in (and props off)

When is a naze preferable over some knockoff cc3d with cleanflight or whatever other fw you want to dump on there? The prices seem to reinforce the naze as a higher end board, but what does that actually translate into that I won't be able to do with my cc3d? I'm building a new ZMR and I'm not actually looking to upgrade since I have a bunch of CC3Ds to spare, I just don't really understand what the price jump buys me. some kinda jackal fucked around with this message at 14:13 on Jul 7, 2016 |

Oh stm32f1. Nevermind. Yeah I'm not buying boards these days, but I have like 5 knockoff CC3Ds because they were super cheap and I wanted to play around with firmware so I bought them way back. Have no reason to actually upgrade and buy anything new. What is the go-to board these days? I feel like all the new boards passed me by since I'm not really familiar with any of them.

So I've been having a fuckton of issues with the T2D gimbal after it somehow tripped angle overrun protection, and for the life of me the gimbal controller won't talk to the software on a Win 10, 8.1, or 7 PC. The motor controller is fine. I'm kinda done with troubleshooting and thus I'm putting up for sale the FC40 I just got. It's in SA-Mart for the interested: http://forums.somethingawful.com/showthread.php?threadid=3782398 It contains a link to the Dronevibes thread where I've posted troubleshooting steps and results. It may require a new board, it may not, but I figure this thread might be interested.

Martytoof posted:Other than the designer being a douchebag from what I hear, everyone online seems to recommend it for racing for some reason. My own particular gripes are the fast loop times and Multishot. The loop times because apparently people are trying to cheat physics and inertia by just sampling more, therefore ostensibly reducing latency (yeah, because a human can tell the difference between 1ms and 0.125ms in a naturally dampened vehicle), dismissing that with the ever dropping SNR from sampling faster, you need to introduce heavier LP filters, which introduce large delays and destroy said supposed latency "advantage". Not to mention that the update rate from the RC receiver is in the low double digit millisecond range to begin with. And then there's Multishot, because apparently we need to update the ESCs at an insane rate for no good reason, especially given that motor response times due to inertial effects are pretty drat high. I think the biggest joke is that some people run Multishot at 32KHz, even tho the loop times are slower, essentially sending redundant packages to the ESCs. People claimed to "feel" "noticeable" differences between 16KHz and 32KHz MS, despite an 8KHz loop on the flight controller. And the saddest thing is, they claim these high rates for better control accuracy, when the uselessly high command rates disturb the motor commutation that's done in software (and also PWM signal generation in those ESCs without hardware PWM), since the input PWM signal tracking is done using edge trigger interrupts. So yeah, grain of salt advised. As far as the Naze goes, I only fiddled a little with it due to a friend sporting one. In my opinion, it suffers from a bunch of questionable design decisions. What annoys me most is that it renders one of its UARTs useless by attaching an FTDI to one of its UARTs instead of using the native USB connectivity the F1 supplies. Sure, you can disable the FTDI, but then you have to reset your flight controller to hook it up again to *flight. I suppose an SPracingF3 or a Sparky would be cheap alternatives. I think a goon makes the DTFc, which is a combination of flight controller and power board, which seems to perform nicely.

Sure, you can disable the FTDI, but then you have to reset your flight controller to hook it up again to *flight. That's mostly due to the board's original pedigree as a remapped layout of another board ("FreeFlight") that originally used the same components. The CP2102 serial chip on there is simply due to the original board having one.

You won't need a runcam with the x8hg. That camera is a decent go pro knockoff and you can check out reviews on YouTube of the x8g by searching for it. Without the gimbal your video will be jittery but it's the best we can do in your price range. I don't think you'll be disappointed.

If dipoles are that much better in regards of signal strength, disregarding multipathing, why don't I just put one on the quad, and get a triple diversity receiver and stick three dipoles at 90° to each other on it to deal with polarisation? Friend of mine killed his CP antenna yesterday in a crash and helped himself with a dipole the rest of the day, and claimed he had way better picture and less interferences.

I have a double diversity receiver incoming from Banggood (an FR632, whenever that is), I'll be trying dipoles in the open when I get it. I suppose if I'm tracking 160-180° in front of me, two receivers with angled dipoles should be able to deal polarization mismatching. Whenever I do my first race in the parking garage, I suppose CP antenna is mandatory.

Read about that. Unless I get something from older stock, I should be fine. Hopefully.

Has anyone else done an 1104 build? I have mine tuned in Betaflight 2.8 and the rates are just so slow. I have P1 R1 Y2 rates in the PIDs screen, and an RC rate of 1. I've got NO expo selected and it still only responds like my 210 does with .70 expo. That's fine for normal flight, but flips and barrel rolls are basically out of the question unless I gain altitude. Am I missing something?
