Earlier today, I posted how the p3p is more finicky than the p2v+. Little did I know that I was going to encounter a "new issue" the same day. When I turned the power on the remote controller, within 5 seconds it started to beep and the status led started to blink red. The manual only says "remote controller error", and I did not see any steps to troubleshoot this. Tried to turn it off and on to no avail. I then changed the battery on the bird, and it beeped twice and then it turned green. I was surprised because I do not understand the correlation between the two. I flew it OK. Later today, the same thing happened again, and again a battery change caused it to stop beeping at me. It is baffling because the cells voltages were all OK, the compass MOD was ok, and the app was saying safe to fly. So what is it? does anyone have experience with this? Is it just a coincidence that changing the battery stopped the beeping? I would like to know the real issue so that I can take care of it.
