Urgent > Need Help with Flight Time

Hello Everyone,

I need to complete a prototype as soon as possible. Requirements for that are

  • 5 kg Payload
  • around 30 minutes flight time
  • Quad or Hexa > Both configs are acceptable
  • Wheelbase can be 1000 - 1200 mm

Here are some of combinations that i tried to make on eCalc

First one is too expensive due to its motor types

Second one has way cheaper motors but flight time has been affected greatly

can contact us?We have another plan here.
