Phantom 2 (non-vision) had bad crash. The link indicator light was always steady red (no 2.4GHz signal detected) even with remote on, so I thought that maybe RX broken. I plugged in a new RX. Now when I press on the link button it does blink red, but after I release it, the link indicator does not turn to green. Instead, with remote on, it is off. If the remote is off, it goes (correctly) to steady red. Thinking of maybe trying another NAZA MC, any other better ideas ?
