Live in Texas. We are in the 100 degree range all week. Should I be flying the Phantom in this type of heat? Flew it yesterday at about 3 pm while it was 100 degrees and was quite worried it would sputter out. ALSO, if I am flying in the brightest part of the day what is the best ISO I should use when filming? Not real happy with the video I got yesterday at 3pm with my ISO set on Auto. Appreciate the help!
