Best way to bind to flysky 8 channel receiver?

i am building a hk450 and i am going to use the flysky 8 channel receiver. i have the devo 7e with the module installed out of a v911 radio. i use a fixed id on my v911 and v912 because i found it to be safer than reinitiate, i have had my v911 drop out of the sky before, but once i set a fixed id it never happened again. so i wondering the best way to bind to the 8 channel receiver or what fixed id to use? any help would be greatly appreciated.
