After I updated the firmware of my Typhoon H I have had a problem getting this error message on the screen that CAN NOT be cleared off without powering the ST16 down and restarting it. After restart it's gone until I touch either one of the trim buttons again and it's back and will not clear... Anyone have an idea what's up? I spoke to Yuneec today and they had me reload all the firmware and try again but it's the same. Any help would be greatly appreciated. I'm not a tech tard but I'll be the first to admit my 28 year old son can walk circles around me when it comes to this type thing. He tells me for a 52 year old I do better than most my age but I'll admit when I'm lost and I'm lost on this one.
