Our last job with the ALTA / M15 / CONTROLLER + Canon 1DC / CP14 to 85mm. Flying only with 2X4500 to get about 6min!
Speechless. What an amazing opportunity, and incredible skills and artistry to make the most of it. Bravo!!!
Looking sexy as hell! Why would you fly with such small LiPos? Did you exceed ALTA's payload limits? Hope you didn't fry them, these little 4500mAh guys can't keep up with current demands of big machines.
If you have high-quality batteries with very high 'C' ratings (like 45-65) it's doable, but I can't imagine you'd have more than a couple minutes flight time. And the "reserve" would also be severely limited. In other words, you'd better get your shot in a hurry.
Well! I've done this shoots having 6-7min indoor. So plenty enough in those conditions! Also flown with 2x4500 (25c continuous) with A7s2, for lightest set up (10,1kg) to fly at 4000m, also had 7" flight time from 2600 to 4000m in Nepal! Alta's great unit!
