Best Combination of Motors, prop and batteries for the X-UAV Talon for the Longer flight Distance

HI,

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:

Joffrey, is your goal maximum duration or range?  Why the 17X5.5 propeller?  Why 5S?

50 minutes will be verry good !
17x5.5 because i've take the extension for the talon V2 frame and 17" give more stability and flight time and i need of this to do FPV.

5S because i already have the batteries for another rc (MT4 G3).

you will break the prop if 17" everytime you land. 

You don't need more than 13" and you will get 60 minutes minimum, you saw my summary and it was a flight full of circles which means it has consumed more energy than cruise mode. 

it's Ok for 5S, your AMP will be like 3 most of the time. 

Turnigy 3548 900Kv, APC 12x6 electric prop,

Because I had it from a previous project !

Yes, I have the wing extensions.

At the moment everything is set up for 60 Km/h, I did not gain much current wise to drop the airspeed to 40, and I wanted to cover as much ground as possible.

Lost my flying field, so I'm not doing much at the moment.......

I've tied the config on 17" with e-calcs and i got this with RcTimer X6 motors (X6 Motors):

If i try on 13" i loose flight time

Joffrey, are you talking about a quadcopter?  Perhaps I'm the one confused, but I believe Elios posted about power systems for this:

Oh yes i'm talking quadcopter, i don't understand because my frame's name is "Talon" too

"Talon" has wings, and a motor at the back.

"Toys" have 4 motors on top, and the less said, the better :-(

It's a translation problem.....

@Joffrey, I don't know who the manufacturer of your quad is, but the Talon fixed wing (as pictured above by  Trung Nguyen)  has been well-known with-in the community for a couple years now.

Sorry the quad company didn't pick a new name for their craft.

Hi Dave,

I am planning to start a Talon UAV Project and try to obey your advice above.

My configuration is:

- Sunnysky 3508 580KV

- APC 12x8 and Turnigy Wood 12x8

- 4S 5000mAh x 2

 

But, I have a confusion about ESC selection.

In the description of Sunnysky motor, it says “25A max continuous current”.

But in this forum, everybody is talking about 80A, 100A esc.

I wonder why?

I think ZTW Spider 40A opto is enough, isn’t it?

Which esc you can advise for this Sunnysky?

Regards…

Go for the Castle Edge. http://www.castlecreations.com/products/phoenix-edge.html  75 or 100

or http://www.castlecreations.com/products/phoenix-edge-lite.html   75 lite or 100 lite. 

They are the best.
