I went out with my pal last night for a flight (my P3A and his P3P) we set up and started waiting for the crafts to warm up, by my friend noticed that he was getting a warning that there was strong interference and be careful on long range flights? This spooked us a little so we didn't fly at the same time in the end. If I walked away with my craft the poor signal would change to good? It seemed to be my craft interfering with his rc and visa versa. What do you guys think, was it perfectly safe to fly?
