Hi All. I have a standard P2 H3-2D with no mods. Having flown it without issue I messed up big time 4 weeks ago when I lost sight of it while flying over an island. After a short attempt at bringing it home using home-lock I became rather worried and turned off my RC hoping the Fail-Safe would bring my bird home, but it never arrived. First I concluded my P2 was lost in the ocean and gave up. After thinking about it in the cabin later that night I started a Drone Crash investigation that led me to locate the "wreckage" 2 days after the crash. The P2 was in excellent shape considering it had flown at cruise speed into a tree and fallen about 15m to the ground. The battery had been ejected at impact and was about 5m from the P2 itself. Apart from a small crack in the top chassis above the USB port no visible damage could be seen. Regrettably there had been serious rain during the time my P2 spent in the forest. So naturally I dried it in rice in my bathroom with heating cables in the floor. So Here is the problem: Neither my Mac nor my win Vista OS Pc will now respond in any way when I connect to them via USB. I see people have had various problems after connection, but I can not do anything. Typing in the S/N in the appropriate box does nothing. The only other problem noticed initially is that I cannot connect to any computer. The RC connects fine, but plugging the P2 via usb does nothing. No response at all The NAZA unit seems to be working fine. Testing it whith no props confirms that it opposes any movement e.g. when I do manual tilting or rotation. So far I have opened my P2 up and checked all connections as best I could. I have unplugged and checked for visual damage, but have found nothing wrong. The only thing appart from not being able to connect via USB is that the compass can no longer be calibrated. Flipping the left switch 6-10 times does nothing. My conclusion so far is that there is something wrong with the compass unit. What are the chances that I would get all up and running by changing the compass? Can a faulty compass be the reason my usb will not connect? Hope someone can help.
