I am a complete newbie. I used to have propeller guards attached to the Phantom, but decided today to remove them. I used the same screws that where attaching the propeller guards, which are longer than the original screws. I think it may have damaged something. Now the Phantom wont start properly, the propellers just keep spinning back and forth. I have uploaded a video to show the problem: http://www.youtube.com/watch?v=4QGpWK3VgCs Any help is greatly appreciated!!
