I am a sales rep.. out on the road most days. I have my new P3 in my trunk (in a travel case). The heat has been hitting 99-102F in Texas which means the interior is much hotter. I don't have the option to carry the quad case in to each of my 2-4 appointments, so not sure if A) how does heat effect the Quad's electronics? I'm tagging it along to shoot (free) pics for clients and prospects. I bought a 12v car cooler off of Northern Tool, for the trunk, to store the lipo batteries for obvious reasons.. so my question is for the quad. Last night, after it was in the trunk for most of the day, the P3 would not calibrate for 3-4 attempts. After 30 minutes inside the house, when I went back out, it sync'd up and flew fine..... which is why I ask.
