Hello all, We are about to start filming golf courses for our local golf club. It has to be a single shot per lane (flying height about 35ft) so we'll eventually loose the line of sight. The longest courses are about 500m (1600ft). I was actually able to fly one short course with only line of sight but fast realized that I would need FPV system to do it comfortably. I use 1,3ghz dowlink for the camera operator and would like to use another 1,3ghz system for FPV purpose - is this possible without interference? I need the obstacle penetration 1,3ghz system offers because there are lots of trees on the courses. I have 8 channels on my downlink so I could just choose two channels furthest away from each other, would that work? I use these antennas for my downlink at the moment, should I get these same ones for FPV also? http://www.readymaderc.com/store/index.php?main_page=product_info&cPath=11_45_52_100&products_id=552 Most of the courses are almost straight lines and I think that the range should not be a problem. Maybe on the curved ones I could leave the copter in the start and fly from the midpoint for better visibility? Just have to go and test the range of my current setup before buying anything. Thanks!
