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:

Well, then you are already doing better than me.........Almost :-)
I can probably do that with 15000mAh 3S, old 3548 900 Kv motor, two GoPro's, 12x8 prop, and it launches easily in no wind......
What speed are you flying at?
With 23000mAh you should easily do 120 minutes !
Like quad copters, you get to a point of diminishing returns regarding batteries and weight.
On my 3DR quad, 2200 mAh, I get 10 minutes, and a very hot battery.
4000mAh, 15 minutes, cool battery.
8000mAh, 18 minutes, cold battery.
I hope to restart my Talon flying this weekend ! As I mentioned, all my built specs and weights are somewhere here.........
We try to fly around 40-50km/h as the goal is filming animals with infrared camera and shot with a Sony bridge camera. So we do not want to fly fast.
I also wish to get flying again but need to get the new motor...
Good luck for next weekend!
