I am not convinced I am getting enough distance out of my P3P. I suspect the antenna's. I did notice ages back they were loose and I wound them back in again tight. Yes I know about the 11 & 1 position. So is there some function you can use to check signal strength? Done all the usual IMU, compass calibration etc. What sort of height upwards should I be able to get? I only ask because if I try going high I cannot blame terrain, interference etc as much. Not only that I will know where it is rather than risking it going off into the distance. Ideas?
