I have a question I have a P3 stanard it has been working great but I used it yesterday for about 30mins. from a full charged battery. When I landed the drone I went to shut of the battery (hold down the power button ) it would not shut off I tried this a few times same problem. The only wya i got it to shut off was to charge the battery then it shut off. I tried it again in the drone the same problem it will not shut off?. Any idea what the problem is? Thanks George
