Hi everyone, I have a P3(4k) and I haven't really been impressed by the signal I get even out in the middle of nowhere. My max height has been 620ft before I lost signal but it's rare I get that. A few times I've completely lost all signal to the 4k with my phone (LG g4) and when you can't see where about the drone is I get all stressed out that I'm going to lose it. I've read about calibrating the IMU etc away from any possible interference but just how can you find a perfectly flat and level surface to perform an accurate IMU run? Also just out of curiosity does the 2.4ghz outperform the 4k's 5.8ghz signal? I always thought the higher the better bit I'm not clued up in this type of stuff.
