Hello everyone, this is my first post. I am seeking help before buying anymore parts. I found a Phantom 2 Vision that someone had crashed some time ago. I took everything apart and cleaned it up. I have sourced a new battery and a controller (among some other parts [props etc]). I can get the Phantom to power on and everything checks out without any problems. The controls all seem to work with one exception. One motor (rear black) will not spin. It will twitch like it wants to but increasing throttle will not power it up. I have replaced the motor but I'm still having the same issue. Before I order a new ESC I was wondering if anyone would have any insight as to what the problem might be. I'm also having a problem with the camera. This is a secondary issue as I'm really trying to get this thing to fly first. I cannot connect to the camera. I get a whirring sound on the motor of the camera and if I tilt the copter the motor will move slightly like it wants to stay level but that is all. My fear is that the camera is faulty and will also need to be replaced. Thank you in advance for any help you may be able to lend.
