Heavy Lift Quad config for 2kg payload

Posted by Mithil Raut on January 21, 2014 at 2:09am

I'm looking to build a heavy lift quad to support payload of upto 2 kg using the following parts
I found this config on web Grin

Turnigy HAL quad frame
NTM Pro Drive 3530 1100kv motor x 4
Turnigy 9 x 4.7 props
Hobbywing Pentium 40 amp ESC x 4
2650 3S1P Turnigy
MultiWii Pro with GPS controller board

I would like to know if the following config would work or not Huh?. Any suggestions /feedback are most welcome. If any of you have a tested configuration for this payload, please mention.

    hence finally going to settle for a 1kg load...

    Some guy suggested to go for this hex, it appears to lift 2kg and well within my budget. Check the link

    It appears all those components exceed my 300$ budget for a quad.I guess I would be settling with a lower config. Hence decided to reduce my payload.

    Initially I was looking for aerial videos using a JVC GY-HM100 which weighs around 1.5kg. But now will have to settle for a sony camcorder instead. What do you think. Will this config handle atleast a kg?

    If a heavy lift quad is definitely required (as opposed to a hex or octo) Have a look at the u series motors from T-motor, and the Foxtech W61-35 motors, running 18" props. You will need 6S. Your aircraft weight will need to be 3.5kg or less to lift 5.6kg AUW and still be flyable in the conventional way (ie hover at around 50%). I think you'll be cutting it quite fine...the motors alone will be 1kg and a 10a 6S is 1.5-1.6kg...

     

    I recommend looking at the above motors in a hex/octo config.

    take a look at eCalc

    For lifting a 2KG payload with a quadcopter you need some serious motor and some serious prop so you need a larger frame.

    Might consider a Tarot FY650 Frame:

    And 4 Tigermotor  MN4010 475 KV motors

    http://www.rctigermotor.com/html/2013/Navigator_0910/38.html

    And 15 x 5 or 16 x 5 props with lots of 4 Cell LiPo and 30 amp ESCs. 

    Should be capable of lifting 4 KG total (including payload) and leave about a 50% reserve thrust (6kg total) (really minimum needed).

    This is really the minimum needed to do what you are looking to do.

    You may be able to find a motor cheaper than the $86.00 Tigermotors with similar specs, but make sure it is rated to provide at least 1500grams of thrust without burning out.

    You need 15 or 16" props to acheive the efficiency necessary to lift this kind of weight with reasonable flight times.

    And that is why the bigger motors with the lower KV are required.

    I have added this build into the build your own multicopter page in the wiki and I strongly - very strongly suggest you do not build this for your first Multicopter, it is way too high a performance and way too dangerous.

    No, that is not a good configuration for a quad that weighs 2kg, let alone for a quad that needs to lift itself AND 2kg. It will barely be able to get off the ground with AUW of 2kg, and will not be maneuverable. This is not a heavy lift design.
