Can I expect 30+min flight time with 1000mm hexa copter

[traxx2003]

Hello everyone! I've been looking at the Skyhero Spyder 6 hexa for quite some time now. After loosing my Align M480 last June, I've always wanted to setup another large multi. This time around I want redundancy. But I also want long flight times. So is it really possible to achieve 30+ of flight time with a Spyder 6 hexa? Bellow is the setup I have in mind:

Spyder6 1000mm frame
KDE 4014 380KV
17x5.8 CF props
Super X FC
TATTU 6S 16000mah or 22000mah

Thanks!!

But what's the payload or are you just wanting to stay up for 30 mins for pure flying pleasure?

At this moment it will be for just for some long range FPV and extended sessions of sport flying. But I do plan to carry a gopro/ gimbal setup but not all the time.

Now this numbers from ecalc, do they tend to be conservative, or do they overestimate potential results?

With tmotor cf's, I find it to be conservative.

Here's with different motors and a 1 kg over frame weight. You really need to get eCalc, and run the numbers. Your limited by 18 inch props at that frame diameter also.

I have ecalc but it does not allow me to input accurate weight for lipos. For instance, did you noticed the indicated weight for a 16kmah 6s battery? 350g; unless I'm misreading, that is way off. My Pulse 16000mah 6s is at least three times that.

That's per cell weight. The tattu 12,000 is 322g instead of 350g with the Eclac default weight.

That makes perfect sense! thanks fltundra for your responses. It is always nice to receive good info from those who have the knowledge.

I have found "Ecalc" to be way off unless your are flying a very small multirotor

 

[traxx2003]

Really! How inaccurate whould you say?

Then your inputting data wrong.
