I once again had problems yesterday with the ability to turn on the video camera and also switch from photo to video. A new inaccurate error message was also cropping up prior to my launches "No SD Card Installed" when there was one in there that had already written data. The unreliability of this machine after flying 6 batteries in a day is starting to worry me. The H+ may fall in the category of "not suggested for professional use" as each time I use it for a day of flying after a few batteries it becomes quite flaky. I'm flying in temps in the 50's and 60's and in most instances in calm winds but receiving error upon error message and the inability to have a workable camera and inaccurate error messages is quite troubling. The auto download software feature cause me to wonder once again how do I reload what appears to be corrupted firmware / software. It's a bit of a closed loop at this point to me which means zero can be done in the field when problem arise beside keep rebooting and say a wee prayer camera will engage properly. When the unit works properly it produces excellent results but I seriously question its reliability.
