I'm not calculating voltage...

I'm guessing (yeah guessing) motor rpm through siding on the side of caution...'3.5V' jives with what I observe about rpms, not voltage.

Is it the actual voltage? I don't know, don't care, I want to know the limits and I don't know esc, heli weight, blade, etc, etc to tell you more accurately...I'm guessing yes, you're guessing no.

Like I said before, find someone who has done it or go do it, best way to know.

I tested out 14S 4200mAh with a Scorpion HKIII-4530 450kv Rigidheli.com edition at 2000 RPM.

Testing out the power:

Watch at YouTube

Used 2750mAh in this flight. Peaked at 6.1kW.

So DartHeli, what are your thoughts? The video was cool but tell us more Looks like you can only get just over 3 minutes with that setup?

Flying time depends on a lot of factors, RPM and blade size and flying style being the major ones here. At 2000RPM and no collective management heavy pitching with 713 blades, you will not get to 4 minutes of flying time with a 4525 and 12S 5000mAh.

This translates over to my setup too. At 3 minutes, I'm playing it safe for now. (This is the second ever flight I did with the setup)
Based on the mAh used in this flight, I can go to 3:30.

I'm flying 14S 4200mAh 60C lipos, but based on my eagletree log I'm confident that I can get away with 35C lipos. Going to 4600mAh 35C will give me more power and this will be the same weight as my previous 5200mAh 35C 12S set. This should give me 4 minutes of flying like I did in that video.

Going to 1900RPM and doing some more technical flying will give me 5 minutes easily.
