There are a few things I don't understand and perhaps you guys could explain:
1. The pilot switches to the ATTI mode, which my understanding was that it does not use GPS. So how does he maintain altitude (avg. 30 meters) and speed (avg. 17m/s) so accurately for the entire trip?
2. The average altitude reported is about 30 meters above Home Point, what sensor is the Phantom using to report that altitude in ATTI Mode?
3. The little yellow "H" in the battery indicator, what does it do and how does one use it?
4. I thought that LiPo batteries dropped voltage abruptly once they get to less that 20 to 25%. This pilot's battery seem to have lasted for ever! When I get the first alarm I start to sweat and quickly bring the Phantom back! Am I being too chicken too early?
