Hi, I had my first crash today, it was a terrifying experience! I an attempt to get nice straight down photos for terrain mapping and producing orthophotos i removed the original camera and replace it with an small Ixus (135 g). See pictures. As always I wait for the fast green lights to come on before lifting off. But this time as I hadn't the camera plugged in I couldn't see the number of locked satellites etc. I took of 2 m up in the sky and noticed the Phantom not holding the position so good. It was slowly moving around. I thought it might be due to inbalance of the center of gravity of the camera. So I adjusted it slightly while the Phantom was airborne and then flew up to about 50 m. Then I flew some stretches back and forth letting the Ixus take pictures with the intervalometer. However when I was about to return home the Phantom started behaving strangely and all of the sudden it started going in some kind of big circle and I was loosing control. To make this story shorter I will jump forward. The phantom crashed in vegetation (reed) and seems OK. I started to think this could be compass related after searching the forum. You can se from the picture that the compass unit was slightly higher than original location. Also I striped the wire from the camera next to the compass. After the crash I hooked up the Phantom to DJI assistant and could read the Compass Mod value to about 2300. As I understand this is quite high. I moved down the compass to it's original location, did a compass calibration and Basic Cali and got the value down to 1730. I tried moving the camera cable close to and even next to the compass while connected to the assistant but the value only change slightly (5 units). If I put the camera next to the compass the value goes up to like 3500 and this would of course be an issue. But in the location the Ixus camera was placed during the flight it doesn't affect the mod value. So my question are: Could the compass mod value of 2300 alone have caused the crash? Isn't it strange that it all of a sudden started behaving like this? The battery was still well over 50 %. Should I be afraid of flying the Phantom again and what precautions could I talk not letting it happen again. Of course I shouldn't be flying if it spins in circles and maybe even calibrate the compass every flight. Hope someone with experience could shed some lights on this.
