Interesting situation. I just got my Typhoon H controller back from having a broken OBS switch replaced. The form inside the box says the controller was reset. One would think I would have to rebind my controller to my H. Not so, it worked out of the box. Here's the issue, ever since I got the controller back, I get a low battery message after 10 minutes of flying. I have two new Yuneec batteries and one Ultrex battery. All them charged on the factory charger, all get the error message at about the same time. It wasn't an issue until I got the controller repaired. Is there some setting I am missing? 10 minutes of flight time per battery doesn't seem like much to me. Thanks in advance for the help
