Hello, I'm planning on building a super heavy lift x8 multicopter for agriculture, it will be carrying at least 10kg and I'll need at least 30 minutes of flight time, could you help me selecting motors, escs, props and frame?I'll be using an APM 2.6 flight controll board. Also I'd like to know what battery should I use
Thanks for your help guys

Propeller choices are VERY limited in larger sizes. Look at the motors from KDE and T-Motor for starting points and compare the performance data available from each company for their product lines. The data sheets list out some pretty good starting points for thrust generation with different props and voltages and provide efficiency values that can be used for input data in programs such as eCalc to help you narrow down your choices. 10kG and 30 minutes are two criteria that don't often go well together, but it can and has been done. For aerial mapping one does not need to fly that long. For some aerial agricultural applications a multirotor is not the optimum choice.

I've been looking at t-motor, but every time I try something in ecalc it says that there isn't enough power or stuff like that, I don't if it might be a problem of the props or what, could you suggest me a good combination? Thank you very much for your help

Have you ever built anything like that before? It's one thing to put a little quad together, a bit more to put an octo together, but you're looking for something that would need the size of a small car battery to power.

I guess I was a little too delicate in the way I was telling him;) Glad you stepped up to the plate. Reminds me a bit of when I was a lot younger when my Grandfather told me my eyes were bigger than my stomach. I don't think the OP realizes he'd have upwards of $12,000-$14,000 into the project before he started checking motor spin directions.

Maybe it's that we all wag our fingers at irresponsible pilots who have a couple jaeger shots then fly their phantoms into government buildings, yet we freely try and problem solve how they'll be able to fly around with the weight of 3 cinder blocks in the air. I don't want to piss on anyones dream but when your first batch of questions to a forum is how to build the Godzilla of all multi's… crawl before you walk, walk before you run, run before you jump, jump before something crashes on your head…

No disrespect to the OP intended.

Interesting to hear of your project. I have a SkyJib (Octo) and am working on making a fold-up one similar to the:
Tarot IRON MAN T1000 Octo-Copter Carbon Fiber Frame if you are interested we can swap notes

You're definitely jumping into the deep end of the swimming pool.
First of all, why would you insist on running an APM board? I don't know of anybody running any serious heavy lift applications with APM flight control boards. Most are using WKM, A2 or MK. Some even using SuperX.
Secondly, while there are some folks like @Kopterworx building and flying machines of that magnitude, doing so yourself with (apparently) little or no experience is a really questionable decision.
Lastly, there are many examples of such builds out there. Google them yourself. Asking for such assistance like this is a little presumptuous.

Sorry to be a hard-ass, but unless you're made of money and time (and an aeronautical engineering degree or two), you're not going to get very far.

I disagree there is a lot of hype over how complicated these craft are but when you get down to basics it is just motors on poles controlled by of few components. All one needs to do is look on U tube and see what other people have made in there backyard(they are very primitive) but they work!! And it is with trying things out that you learn. What dfortu is asking is what people think of the best products to use. It is just a starting point; );-)

Yeah...let us know how that works out for you, amigo.
Those of us who actually fly these big machines know better.

haven't seen one of these in a while. I mean there used to be these kind of post almost daily. Then they dwindled down to become more rare when the s800, 900, and 1000 came out because people could just buy an out of the box package. I think the only sane response is to direct you to start small and work your way up. By the sounds of it you are biting off way way more then you can chew.

This thread actually seems to border on trolling. I don't think it is, and if its not I am sorry. But I honestly can't tell.

Those that have actually made one of the monsters truly understand what it takes to make one happen. Although lots of $$ plays a very big part, you haven't sweated until you take off the first time at 27lbs+ and learned the gains were way off and you have to land it, not crash it, before you can start adjusting anything. It's not as easy as it might look.

Well, I insist on using APM because I want it to be open source so I can make some changes, I want to make a 100% autonomous flight with loads of waypoints
