As for your video, I can only give it a 9.9 out of 10, because I wasn't there. That's about all the criticism I can come up with. Way cool. Nice variety and no crap. Life is good.
I'm gonna hijack your thread a bit
On to more serious stuff, like trying to fly at high altitudes. Which Phantom are you flying?
100% of my flight time has been between 4,500 and 8,000 feet msl. I may not know diddlie, but, batteries need to be able to keep up with the draw of the motors. Yes, no, maybe?
I'm betting DJI batteries aren't designed to discharge at the rate required for flights above 10,000 feet. Hence we encounter an anomaly. I'm flying the FC40 so I have choices. When I fly at 8,000 ft with a 10c discharge battery, I have to wait for the battery to catch up. In other words, if I take off and climb vertically at a high rate, I will almost immediately get a red light flashing on the FC40 which indicates low battery. If I ease up a bit on the throttle, I will get flashing green, indicating the battery is not low and I can continue to fly with that battery for another 5 minutes or so. 5 to 6 minutes is all I typically get at 8,000 feet with the way the bird is loaded. My flight time is almost twice that at 4,500 feet.
If I fly with a 35c discharge battery at altitudes up to 8,000 feet, it flies till the battery is drained without hesitation or an early indication of a low battery. I could probably get an early indication of a low battery without too much difficulty at 10,000 feet or more. That’s just speculation though.
Maybe I’ll find a 50c discharge battery and climb a mountain so I can test this theory.
