I am new member in the X-UAV Talon club, I have just received my Talon with the extension wing.
I'm working to put the right combination of motors, prop and batteries:
I am looking to have the maximum flight duration over 90 minutes.
The weight of my FPV gear with all antennas, cables, cameras is around 750g.
The weight of the talon + motors + ESC + servo is around 1400g, So the total weight without the batteries is around 2150g
Regarding the battery, I can use multiple options based on motors and prop:
Multistar Battery Weights:
3S 5200 mAh is 325g.
4S 5200 mAh is 433g.
Option1: 3S configuration 2 parallel batteries => 3S 10,400 mAh: 650g. Total flight weight 2,800g
Option 2: 6S configuration, 2 series batteries => 6S 5,200 mAh: 650g, Total flight weight 2,800g
Option 3: 4S configuration, 2 parallel battery => 4S 10,400 mAh: 866g.Total Flight weight: 3,016 g
Option 4: 3S configuration 4 parallel batteries => 3S 20,800 mAh: 1300g. Total flight weight 3,450g
Option 5: 6S configuration 2 parallel + 2 series => 6S 10,400 mAh: 1300g.Total flight weight 3,450g.
What motors and prop should we use with every option, and what flight duration will we get?
I have those motors: but I can buy others if needed:
