good afternoon folks. I’m new to this sight and find it to be very informative!  I was wondering if there is anyone out there that can help me troubleshoot my Phantom 1. I know it’s old but it used to fly pretty good until it went ballistic after takeoff.  I recovered it from my neighbors roof.  The blades have been replaced but now after the the GPS is aligned it just sits there.  The controller beeps constantly.  When I flip the switch it stops beeping but won’t takeoff when commanded to do so.
