a bit of a tool question: i hate soldering plugs, as i inevitably end up melting two or three of them before i get it perfect. would http://www.ebay.co.uk/itm/Aluminum-jig-Soldering-Aid-Station-adjust-heat-insulation-XT60-XT90-TPlug-Bullet-/391118314140 help me get rid of this issue? it's pretty cheap and multi use, and i've standardised on XT60 plugs for all my uses anyway.

Frobbe posted:a bit of a tool question: Those tools certainly make it easier. What soldering iron are you using? I melted a lot of stuff before I invested in a good temp controlled unit (I use the Weller WES-51), the cheap irons took too long and heat got into the plastic and melted it. Using 60/40 rosin core solder at about 700 degrees also really helps especially compared to RoHS compliant solder.

Frobbe posted:a bit of a tool question: Are you in the UK? just wondering if that is why the ebay listing is on UK site. I am asking because there are other very useful jigs than that thing. My two favorite tools for this are http://thejigsup.net/ and http://www.amazon.com/gp/product/B00CD9YIB8/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1 with 3rd arm. Between those two I can solder any connection easily. I know the Jig is up is US centric though some uk places might carry them. The progressive RC one just needs some silicone buttons or just spread some silicone on the bottom to keep it from sliding around. Both are excellent helpers. For soldering XT60s take a spare male and female and put heat shrink over the connections. Then when you go to solder one mate it with it's opposite (that has the heatshrink protecting the terminals). That way it gives you more thermal mass and if the nylon does warm up it keeps the pins from changing position.

I had my first good Z3 flights yesterday. Still getting it tuned out. On this flight I didn't use my low rates and need more expo so it is a bit twitchy but I am really happy with how it is flying. This plane is going to be so much fun. I got confused on the landing and almost landed by the wrong people standing by the road  https://www.youtube.com/watch?v=HqFXqxJRl8Y

What are some of the recommended approaches to a flight controller with modifiable source-code? You can use an Arduino with MultiWii, I believe, and ArduPilot appears to support a variety of hardware, including the PixHawk, which is the main one I was looking at.

I bought some motors and some cheap Neewer ESCs. The ESCs have just three blue wires coming out to the motors, and I have no idea how to wire them. Any advice? You can see the frame, the motors, and one of the ESCs there.

It doesn't matter. it's 3phase. Just wire them up, and know you'll need to reverse a set of wires on at least one, if not three of the motors. It's not a long process. On a personal note. I flew my RedBull 130x this weekend. I made it four batteries in before I stripped the tail rotor drive gears. Again. We're down to $0.50 a flight.

These days with bllheli and Simon k, you don't even need to physically reverse the wires. Just wire them straight and neat, and reverse the two that need to be reversed in the firmware config

Just for gawd sakes please take the props off before testing these. stick some tape on them to check rotation easier. Especially if you are just getting into this be careful around props or google rc prop strike if you are unsure of what can happen.

I feel privileged that my ESCs and motors had banana plugs and that I didn't have to solder those. What everyone else said: Don't attach props when testing, swap any two wires if a motor spins the wrong way. Not all firmware supports switching them without physically swapping the wires and it doesn't take long. I'd honestly recommend soldering banana plugs to the ESCs and motors anyway so they're easier to replace or adjust versus having to re-solder every time. Edit: a foolish pianist posted:Oh, I've already been cut by Hubsan props. I'm plenty cautious because of it. Hubsan props might as well be foam for how much more the 450-scale props can maim you. We're talking broken finger bones if you use carbon fiber props. I've found that the DIY quad stuff lacks in documentation in general, sadly. ESCs are at least foolproof and can't be wired "wrong" in terms of current flow, so it's a quick swap to fix motor direction issues. Mina fucked around with this message at 23:44 on May 4, 2015 |

Yeah, its been lots of digging through 100 page threads since the OP are woefully outdated. If your lucky, you'll get some sort of engrish manuals with some very basic instructions. And the first time my 250 quad with 6x4 props was in the air in-front of me, I had the immediate thought of "What have I built? This thing is going to kill me!". I can appreciate the concern over them flying near people. I've found here and FPVLab to be fairly helpful. Doesn't hurt the Fixed wing and OSD developers/contributors are still active in the threads. Pushed out to just over 850M today. http://imgur.com/a/htV3E#xZ81akU Going fairly smoothly other than GPS making GBS threads the bed on turns. Guess what RTH is liable to make the plane do. Makes for a bad combo.

I need to speak up on this one. This is a mistake. For five minutes of re-soldering, you save several methods of screwing up, or having your quad screwed up later on. You're adding resistance, and that limits peak power, and if you aren't limiting peak power, you're at least burning more power that could be flight time instead. If you really, really, really, hate soldering? Spend $5 on some alligator clips, and wire up the ESC to the motor for testing using alligator clips. And if you really, really, really, hate soldering, ask... you're doing something wrong. Soldering should be easy, if it's not, I assure you, we can tell you the tricks to make it easy.

Fair enough, I didn't think about the fact that they'd be adding resistance if they weren't designed to be there to begin with. I agree that soldering is easy though, that's not something that takes long to learn either.

I'm a giant moron that fried a painstakingly assembled and tested mini camera/tx combo that I got piecemeal from here and there over months as a side project by - after it was all complete - deciding in bits and pieces between work here and there today to power directly from the multicopter instead of from a separate 3.7v cell and proceeded to of course fry it with 11.1v direct wtf i was thinking i can't even begin to imagine i had numerous opportunities to realize what i was doing and didnt i even took it all apart - the glue had barely dried - trying to find a short or something before i finally realized what had happened gaaaahhh i r dum

Heh, i tried to place my first ever order from hobby king yesterday and their site was too hosed up, i could never check out. I used the support chat and the guy came back with some standard bs about clearing cache, using another browser, updating java (seriously? your site uses java to check out? what is this 2001?) I just told him nevermind and found a different battery and charger on amazon.

How long is it taking to receive stuff from the international warehouse these days? I'm hoping to have my build done by the first weekend of June, but if it's going to take longer than a month I'll probably just put it off a bit longer. I only need some batteries and that foam goggle box from them.

follow me mode is available in some form on both 3dr and dji platforms, and they are just doing the thing parrot is doing for video with the ultra wide viewpoint + digital stabilization. $500 for a preorder is not enticing either considering it comes out next February and by that time you no doubt will have had multiple opportunities to buy a better craft with the same features by then. Haven't there been 2+ kickstarter multirotors with follow me as the major feature last year? are any of those actually out?

None of these follow me drones have any sort of sense and avoid built into them. When these hit the market as a consumer product there are going to be so many of them smashing into trees and powerlines etc. It would be like going skiing towing a baloon behind you on a rope. Only a matter of time before that balloon snags in something. But hey gotta get that sweet kickstarter money. Personally I don't like the idea of follow me mode without proper object sensing as you are pretty much saying "gently caress it, drone probably won't crash". Then you go and do your  moves down the mountain and look back and oh poo poo where is my drone.

I wanted to upgrade my little FPV quad to a 2s setup, so I got these ESC's from Hobbyking, the YEP 7a: http://www.hobbyking.com/hobbyking/store/__37944__Hobbyking_YEP_7A_1_2S_Brushless_Speed_Controller.html To pair with these little 3700kv motors http://www.hobbyking.com/hobbyking/store/__7025__AD_C5_Micro_Motor_4_6g_Weight_3700Kv.html All the specs in the description lead me to believe this ESC would pair well with this motor. Was I off? My quad will spin up, sort of "hop" off the ground an inch or so, then cuts the motors and plops back down. I thought it might be the FC vibrating and causing problems, so I switched to an entirely different frame that is much more solid and I still have the same problems. Has anybody experienced the hopping problem before? Are my ESC's underpowered? I am running 2s, 2x1s batteries wired in series. I have seen others do this before with no problems.  Thinking it might be the switch, I bridged it with a big glob of solder but still had the problems.
