Payload: 5 kgs
Flight Time: 45 - 55 minutes.
It will cost you a bomb..that is for sure :p . You would need U8 motors and 26 inch props and lots of them.
5Kg payload and 50Min flight time ???
Can this be called hobby or is it for Military use ? :giggle:
How ever, Allthatido(don't know your real name sir.) is right.
Let me put this way:
System should be capable of lifting 5 kgs.
Total Flight time should be 45 - 55 minutes with or without payload.
is this 5Kg all up weight or just the payload ?
all up wait : means the total weight of aircraft + payload.
its only payload..
Whats your budget? Are you already a multicopter pilot?
No limit on budget...
Piloting not needed.
Well, then I could say it can be done (as you said no limit on budget :thumbsup:)
But what d'you mean by no need of piloting :headscratch: is this for safe keeping in a shelf after building ? Some one have to fly it one day, isn't it ?
Please don't worry about piloting.
Just post average cost, if it can be done...
Here i found this data from RC groups,
http://www.rcgroups.com/forums/showthread.php?t=1372744 (http://www.rcgroups.com/forums/showthread.php?t=1372744)
with some mods on that and may be an Octo, you can definitely achieve that payload carry capacity and flight time.
if you want I can search and find a suitable platform.
Rough calculated an AllUp weight of around 10 - 12 Kg.
You could go for an Octacopter for more stability.
So AUW be 12Kg, each motor should provide more than 3Kg Lift.
Let me search.
What is your intended payload? It can definitely be done with limitless budget. Use t-motor electronics, custom made CF frame, some A-spec nano tech batts, cf props ofcourse and a dji a2 or wookong flight controller. I would say around 4-5 lakhs. About $8000+.
Thats a good price.
How much does it take, for someone to build it and deliver.
What is your time frame ?
As 4-5 lacks is a good price for you it's easy to build one.
p.s not my business, still can't wait to ask, what is your purpose with this heavy lifter?
4-5 Lacks is not at all needed if you know where to and how to source parts.
What time you can deliver?
Purpose is confidential.
4-5 lacks ,woah thats a nice budget you got!!!
can you share the purpose of building this expensive machine?
and do you want the multirotor to have higher stability or higher motion??
i think this is the thing you are looking for: https://www.youtube.com/watch?v=vxoQaaI3-7A (https://www.youtube.com/watch?v=vxoQaaI3-7A)
you can buy it ,its 6,999$: http://onlyflyingmachines.com/product/ofmgq8octa/ (http://onlyflyingmachines.com/product/ofmgq8octa/)

Rohan, his purpose is CONFIDENTIAL .!
OFM products are good, but the link you gave, can it load 5Kg on it's belly and keep it's wings spread wide in air for 50 min.s ???
If yes, that's what this guy is looking for.
i didn't read that reply(was typing at that time)
regards
That's a nice platform...
I am looking for something smaller in size...
it can lift 6-7 kg ,you can add a couple of batteries ,will increase the flight time.
How confident are you, in terms of reliability of such a build. Have any of you really built such platforms in past.
then ,i will suggest a X8 configuration,it is a quad in which you mount 2 motors on one arm so the as in a octa the size increases because there are 8 props ,in a X8 there will be just 4 up and 4 below so the arm size can be reduced.
well i have never build such a machine but i think there will be a few people who would spend that much money on a project.
but you should ask alishanmao ,the guy is a lot experienced and if you dont want to build the multirotor yourself ,maybe he can build it for you.

Thank You all of you..
A multirotor like this can be seen as a serious security risk by government agencies. It can cause real panic if people find that it can cary payloads of up to 5 kg for such a sustained time. In the RC/ drones debate, one of the best arguments modellers have is the limited flight time and payload capacity and a machine like this would get rid of both limitations. I think that it is important to know the purpose of such a machine before proceeding.
The purpose is only for getting an idea how much it might cost in real world for anyone to get it done.
I like that. !
well,i agree with @SK1701 but we can't force you to tell the purpose so buying or getting it built from a professional would be better as a professional like alishanmao sells these big machines ,so has information about legalisation of such multirotors.
may i know what size of multicopter are you looking for ?,as the one i recommended has more than 5kg payload capacity and 30+ flight time which can be increased by adding a lipo.
I am only studying on what are the possible builds for such a capable system and how many really think it can be built.
with resources and experience anything can be done ,you have the resources but if you need advanced experience in multirotors to build it yourself
ok.. what is advance experience means..
The advance experience refers to the frame design and manufacture(if you're going to make it yourself) , motor sourcing , battery sourcing ,advanced flight control board like DJI NAZA,A2 ,WOOKONG - as nothing is made in INDIA and everything is imported and importing -> customs , bribe to customs to release a such a costly and important shipment ....and so on
ok..
i meant if you have alot of experience with multirotors and flight controllers ,like an electronic engineer has knowledge about the electronics and the knowledge to program some flight controllers like the ardupiolet ,multiwii ,and if you have built several UAV's before you gain alot of experience ,as the first multicopter is considered the hardest one for someone without experience.from how long have you been in this hobby?

Quite a while...
did u see that idea internet network advertisement :P juss kidding ( talking quad ) lol bdw if u r serious u can build it ...........
Just talking from Technical Point of View, The biggest hindrance that i see in such a multirotor is "to design a setup which can fly at 1C (including Payload)"
Otherwise, how are you going to get 50-55mins flight time?
Not sure why people are recommending Nano Tech A-Spec LiPo's, when you actually need just the opposite. :giggle:
Low C Rating LiPo's would be better due to lesser weight when compared to higher C Rating counterparts.
Even if someone is able to design a super efficient multirotor which can hover with it's weight + Payload at 50Amps, he would still need to add in a whopping 50,000mah LiPo (that's 1/3rd of what the battery in your Home UPS can store) which would weight another 6-10KG (6S LiPo)
Basically you need something with AUW 15-20KG with flight time of 1Hr.

Exactly Pointed the facts..
Its possible all you need is a huge battery pack made out of panasonic ncr batteries
Double the cost and half the weight
Using tbs 3-6s lightweight escs
And u8 motors
With a custom made cf frame
Will take around two months of research to get the perfect thing and price can go upto 20 lakhs
But its possible
I have a 40 mins flying copter with a gopro two axis gimbal and video tx
Foxtechfpv`s d130 and k130
I guess he needs 50 mins flight time
Well they offer 7kg payload and 38min flight time.
So if you add another battery of 2kg you can easily bring the flight time to 50min.
Experts please correct me.
I have flown them u dnt get 38 mins
Oh!!! Wow You have flown them.

If this is just to know if it can be built, yes it can. You can get 2-3 hrs flight time 5kg+ payload and require approx limitless budget. Most of the quad will be classified military equipment not available to the public, so you will also need connections to get it. And yes 2-3 months time to design and build it to your specific needs by a expert team of electronics, mechanical and aeronautical engineers.
Bhavesh sir, my bad forgot the batts need to be highly efficient rather than have a high output.
@rcbeil21 thats exactly what i said buy some people prefer taunting then sharing knowledge
