Nice day in the great North West. So off I went to fly my P3A with a new iPad Air 2. Ran two batteries out and went into the house and came out with my P3S. Wanted to use the iPad Air 2 with the P3S as well. Could not get a connect with it so used my iPhone 6 plus. Got a connection and all was well. Ran another battery out and landed and exchanged battery. Was up for about 5 mins when the iPhone shut down. Controlled the P3S back and landed. Powered up the phone again and when up again but not far away just in case. Sure enough it powered down again. Landed and came in side. Any ideas? I did shut down the iPad so that is not it. I came inside and was able to connect the iPad to the P3S so don't know why I could not out side. Stumped.
