Hey everyone .. I have a P3P I got it 2 months ago and have 40 Flights on it .. I didn't update any firmware out of the box .. Everything seemed to work fine out of the box .. And have had 40 successful flights .. I always hand catch on landing.. Never flew on a cold day and never flown in tempeture above 28c .. I always do a detailed inspection of my phantom after every flight checking for cracks, loose anything.. And I always take a sniff inside the battery capartment for any unusual odor .. Also i keep my phantom very clean from and dirt or dust... I did 4 flights on July 20 and upon inspection after the 4th flight I saw a Black Dot ( pea sized) inside my batter capartment of the phantom.. It looked like a cigarette burn on the bottom part near the fan i smelled the inside and it didn't smell burned or anything and I tried to clean it but it was nearly impossible.. I had to use an alcohol pad and I finally removed it with a fair amount of rubbing ... What the hell was that? Where did it just come from?? Anyone else have this happen to there P3P ?? I also checked the batteries and everything is completely normal ... I'm wondering if I should be concerned about this??
