I did my first test flight with my Zenith 750. Just after I got airborn the Skyview went blank. I shut it off and turned it back on but no help. I then shut it off for 15 minutes. When I turned it on that time it came back on and stayed on for 45 minutes and that was the rest of the flight. Has anyone had that kind of problem. I'm now looking for a backup. It's not fun having only a Magnetic cumpass to look at.
