    Think they run a 17" prop so there's 2kg just on motors & props. Assuming this is by four. possibly on a 500+mm frame.
    On 5S - 8S 30,000mah. Dang that's a build. Dang that could be a whole lot of you know what flying over the border. :D
     
  4. thank you for your valuable suggestion mozquito1. Can you also help me how to select a motor by the propeller size? Thank you !!

  6. let us suppose 15x7.5
     
  7. And while searching for motors i also got through a T motor MN 3520 whose weight is almost 200g and its thrust is around 3.5kg. Do you think this is a wiser decision?

    It's closer to your original requirements.
    I think you will find its a bigger prop than a 15" to get that thrust. Maybe a 22"
    You give no weight or idea what for but I would buy Tmotor all day.
     
  9. payload around 5kg

    Excluding frame, So for that weight it needs to be stable & pretty big.
    So let's say another 3kg for frame & lipo & it's guts. Is this for crops or something.
    3kg per motor as you stated. As for the 50% throttle @ 1.5kg you would have to sift through the specs of each motor.
    & my understanding is another 50% makes the 3kg so just look for that thrust in a motor. 100amp esc's for each motor aswell.
     
  11. Including the frame. I guess the batteries may load up a little more weight yeah. It is not for crops though. Trying it for a custom payload .
     
  12. I asked you for custom carbon fiber for the same reason. To make it as light as possible. but strong too.
