Hi, does anyone know the discharge rate or amount while just letting the P1 sit, without motors running? I'm a pro video Director, and I'm going on a Shoot in a week, of whitewater kayakers coming down a river. The challenge is, from the time I see them coming around the bend, I probably only have about 10-20 seconds to get airborne and line up for the shot. So I need to figure out how long can I sit, while waiting for the Shot. I'll do some tests, seeing how much voltage drops at various time periods, I guess. But it would be better if I could be more precise, somehow.
Or, if anyone has a better idea, I'd sure appreciate it. Ideally I'd use a spare battery to keep the IMU warm, then just disconnect and plug in the onboard battery. But I can't get that to work properly. I tried plugging a spare battery into the Phantom, and waiting for a few minutes, well after it's take-off ready. Then I disconnect the spare, and quickly plug in the onboard battery. At that point I get alternating green/red flashes for about 3 or 4 sequences, then a sequence of 3 green flashes, and those 3 greens repeat indefinitely. I haven't tried flying at that point, I'm too worried about a fly-away, especially since my shoot is in a week. And after poring over the LED codes, I can't find anything that matches those sequences.
If I wait about 1 minute after disconnecting the spare, and connect the onboard battery, It's ready to go in about another 45 seconds. So that's 1:45 total ... way too long.
FYI I'm using a 3300mah battery and a Sony Rx-100, so I normally get just about 7-8 minutes of flight time (but the Sony makes it worth it!!!) I know, I'm beyond the specified payload, but it actually gives me some amazing, very professional results.
Any ideas would be appreciated!
