I just got the Phantom 2 and did the calibrations. The process went as expected... Just to be on the "safe" side, I wanted to test the controls and reactions of the Phantom inside the house. We did the compass calibration and satellite links. I assume the satellite links did not work because the green LEDs on the phantom were slowly blinking (but that's OK and was expected). I had my son lay down on the floor and hold the phantom above him. I started up the propellers and moved the controls. The phantom moved as expected. I even tested RTH by turning off the controller and as expected, the props speeded up because it needed to get to 60 feet (also after a few seconds it tried to change course and apparently it thought "home" was SE). I turned on the controller and got the control of the phantom back again. I am not too worried about the RTH just yet, I will test that part later. Now the throttle was not doing what I expected. When it was in GPS mode, I would increase throttle and then let go (stick pops back to middle), but it would keep going at high speed. And I had to manually slow it down.I thought what was supposed to happen is I can increase the the throttle until I get the right height, then let go and it should stay there and hover. On the other hand, when I switch to Atti mode, I would increase the throttle and when I let go, the props would slow down to idle speed (same as when it is sitting on the ground waiting for take off). I know if I did this outside, the phantom would fall out of the sky. In Atti mode am I supposed to keep the throttle up so stay at that altitude? What about GPS mode? what should I expect when moving the throttle and letting go?
