I decided to open up my P2V+ after my first very windy flight which went perfectly. On close examination I noticed that the area around the screw holes was slightly cracked externally. On opening it up I found that some screw holes on the phantom body were broken off completely and a metal one on the phantom top also came off completely. Why has this happened? I only opened it once to check my ESC and cabling When I closed again I applied a drop of thread lock to each screw. Could I have screwed up and maybe overtightened? What can I do now? BTW The Phantom flew beautifully in Force 6 winds.
