Hi everyone, I recently picked up my first phantom. It flew great for just under a month, but in the last week or so the rx and the tx have been unbinding themselves every single time the phantom powers down. To fix it, you take off the top housing and follow the standard rebind procedure: hold down the button for 2 seconds, wait for the onboard LED to flash yellow, and then turn on the tx. However, this bind is not holding. I am not comfortable flying without the top on, so this is a big problem if I have to rebind the tx each time. Please help me out. Thanks. Alex.
