I can't get my tx to bind to the lemon sat rx in Betaflflight. I setup a new model In my dx6e. I flashed my f3 controller and followed the online configuration instructions but when I go to the rx section choose spektrum in the drop down and save then power on my tx I don't have any control. Ive attached some pics. Any idea what I'm doing wrong. I wire the rx as the diagram showed too. Thx for any help.
