I'm just wondering who else has had experience with flying in high heat environments. I was flying in Northern Zambia today, outside temp is about 36C. My flights were going well until I started to feel like my flying inputs were a bit sluggish, I brought it back to make a landing and was hovering close to my landing spot when I could see the motors stop. I was only about 5-6 minutes into the flight, so the battery still had a good charge. The crash wasn't bad at all, only my #6 boom got a crack in it. The real damage was my 9000mAh 6s 22.2V battery, it was huge and about twice as hot as any battery has ever been after flying. All of my batteries are 3 months old and have no more than 8 flights each. Other than that I haven't found any other faults, so I have no doubts that the battery is my culprit.
