I know this is a silly question. I am just getting into quad copters and can't find out anything about the maximum rotation of the H3-D2 gimbal. Can it point straight down to take a picture? I assume the only way to do it with the GoPro 3+ is to set the camera to take pictures at a set interval and hope you don't run out of space on the micro SD card. Of all the videos I have seen posted, I have noticed there are none with a straight shot down. Thanks!
