I just finished installing the H3-2D and did the replacement MC Board method on my Phantom v1.1.1. Now that I've got it all back together and I attempted my first flight... The Phantom seems very front heavy on tak-off. Unless I go completely to full throttle and jam it into the air, it tips right over and crashes. Is that normal due to the weight of the H3-2D/GoPro? Is there something I can calibrate or adjust to improve the takeoff stability? I did recalibrate my compass after installing the new MC board.
