Yes I am sure it is bound. I figured it out though. The cleanflight reciever settings didn't have it for spektrum. I changed it and am now on my 11th pack.
I am having the same problem. I have set my arm to aux1 in betaflight. it is arming, but the motors aren't spinning. I in my goggles it says it is disarmed as well, however I have set it up correctly in betaflight and on my x7.
