A real shot in the dark!! Are you using a switch harness in all three planes. Yeah all three can not be bad but try moving the battery to the Battery port of one of the planes and retest again turn on the TX first, and then the airplane. I have four AR7000 and two AR6100 receivers and never had to rebind. My planes link quick even if the TX is just a few feet away.
