As a total noob, I'm sure it's staring me right in the face lol! I'm setting up an X8 flying wing and even after selecting elevron mixing the elevator and ailerons still operate separately. The instructions for the mission planner say to click on "save". I don't see save anywhere in the window.
I'm looking at the radio calibration screen. I was following the quick start guide for setting up the radio. It said not to mix the elevon in my radio, but to do it in the calibration screen. It's selected, but the channels are still separate. I'm using firmware 2.73. Thanks!
