the hoodman is great, there is very little effect when looking at the craft and back in the hood to the screen, however there will come a point in which taking your eyes off the moving AC for an instant and you will loose LOS and in my experience not recover it again. It has happened to me using and not using the hood. In particular in the summer months the sun is directly above making for an evenly lit sky which of late has become brighter, it you have any kind of haze which at least in the east coast of the US is common due to humidity, the craft being white will disappear in the haze. I can go maybe 2500 ft in the hazy summer sky, then it's bye bye birdie. I have lost video beyond this distance but was just cautious enough to head back and not complete loose signal, but it is scary.
Hi Maxchief,
Yes, bringing back an Inspire 1 from such a long distant away without any video downlink nor any flight telemetry must be scary!
In one of my cases I referred in Post #1, my Inspire 1 Pro was about 2,400 ft away when my iPad Air completely shut itself down because of the overheat. With only 30% juice left, I could not hesitate for any other option but to merely rely on my last glance of screen just before it died to guess the approximate orientation of my Inspire 1 Pro, so that subsequent RC sticks commands could be boldly applied in order to bring my Inspire 1 back home. At such a distant, there was nothing but a faint white dot on green mountain background available for me to notice my Inspire 1 Pro was still airborne! If the background were a bright sky with white clouds or haze, my only option would be pressing the RTH button. Taking time for me to swap another iOS device in would have been too risky to me, given the limited juice then remained.
Lesson learned. I will never let the iOS device overheat again, by whatever means e.g. using a Hoodman hood, keep it under shade, and etc.
