Hello, I am building a custom 660mm quadcopter using a pixhawk 6c, a 6s 6000mah battery and with a weight of 1750g without motors or props. The max payload I am aiming for is around 3.5kg in shorter flights, but I still want to maximize flight time with lighter payloads (hopefully above 20 mins).
I am thinking of either getting Tarot 4008 martin 330kv motors, with matching 16x6 fold prop, Sunnysky v4008 380kv motors, or Sunnysky high power x4110s 340kv motors with 15, 16 or 17 inch props. I would appreciate any advice on motors to use based on experience as I don’t want to solely rely on ecalc simulations (which state the martin as the best option, 28min hover 16inch prop), but could be unrealistic.
Thanks!
