If you want a cheap setup. You can simply take a gopro set it on timelaspe instead of video mode send it up and every 5, 10, 30 it takes a picture. It's the cheapest easyiest way to get a camera in the air to take pictures or video. Now if you shoot in 4k video it gives ok quality pictures from a snapshot of the video so you miss none of the action if something is below. The nice part is you just line it up get the shot and done. The go pro is limiting in some ways but bang for the buck it's the cheapest option
For some odd reason it made it a double post.
