For someone new at this what you did flying at night was not wise. That video looked more like toilet bowl than VRS or a flyaway. Do yourself a favor learn how to fly during the daytime and above all re-calibrate both the RC controller and your P2 including an advanced IMU no a level surface before continuing.
If you are flying in the phantom mode in the P2 software the center position on switch S1 is not Atti even thou it is marked that way. In order for the center position of S1 to be in ATTi mode the P2 as to be in naza-m mode and when it is in ATTI the rear LEDs will switch from slow flashing green to a slow flashing yellow. If necessary go back and read the users manual v1.4I did whole battery flight before.i switched batteries and got him airborn.3mins all good and then from no where wierd noise from motors goin up down left right.i got pretty scared since i couldnt control it.then i switched to ati and pulled him up when he touched the grass.ill post link on youtube in 20min.
