bought my p3s on ebay a month ago or so ( new ) and have only flown it a handfull of times in beginner mode around the yard....love it so far. im considering adding aftermarket antennas, mainly for video stability, as i have no need to fly beyond los. should i mod the rc before i know if its going to be an issue, or is the loss of video a given and i should mod it now . ( i think if i can get good video feed at 500m in fcc i will be more than happy!)
