I'm confused, After a recent crash I replaced another camera and a motor. I installed new CCW motor and the other three motors are not turning up to speed but instead are osculating, What the heck happened ! Two months ago this phantom was flying perfect and it seems it started to having trouble with loosing the GPS. I pulled the top half to inspect the GPS crystal and other component harness to ensure they are connected securely but noticed one of the motors was jamming and couldn't free spin it. I assumed this was a damage motor and why I replaced it. Would anyone have the solution for this dilemma with my Phantom 2 vision plus.
