We bought a P3P on eBay, says was a 4 out of 5, perfect condition. Drone itself looks good, but could hear something rolling around inside remote. Tried to link with drone, but will not, only get "Confirm Frequency?" message when try to link. Tried manual link pressing C1 and C2, the camera button but did not work. Remote would beep but when press button on drone nothing happened. Remote had pieces loose inside rolling around, so opened it last night. All the screw holes are stripped, right control stick screw bosses are broken out, and stick will move in remote. Cable from HDMI board to main board wasn't plugged in, but when I try to plug in won't stay, doesn't go in as far as other cables do into connector, so won't latch onto it. Told wife to contact seller (her purchase, can only provide assistance) and see what kind of deal he's pulling. Obviously remote isn't original and a pile of junk, don't know what kind of soup sandwich the drone itself may be. Did not come with a camera, so bought one, seems to be ok, but makes a grinding noise when powered up, can feel it in the camera. Seller said it was used 3 times while his was in for repair, and looks really clean and new. Just not sure where to go with some of this, maybe best to just return this one and start over. Into it about $600 now, can buy a remote and be ok, but if drone has issue, might as well buy a new one, which is what I'm kind of avoiding. Was unsure of much diagnostic technique, if I should even bother. Some tips and advice would go a long ways. Thanks all.
