binding new receiver
I've got a Spektrum DX7 (luv this radio) I'm installing a new AR7000 receiver to a new aircraft. I went to connect a battery and stray servo to the receiver to bind it, and it was already bound. My question is: does this happen or is something wrong. I've connected about 7 or 8 receivers to this radio and every one of them needed binding. I'm a little hesitant to install this receiver in a $3000 plane. Am I just being paranoid, or should I not use this receiver?
