[ARC5] Oddball RAX Receiver

[David Stinson]

Take a look at the RAX receiver at:

There's a red stamping under the nomenclature plate.
I can make out:

     MODIFIED FOR OPERATIONAL
         FLIGHT ( sumthin' sumthin' sumthin)
          DO NOT INSTALL 
            IN AIRCRAFT

 Can someone with a Hi-Def display make out
 the words after "FLIGHT" ?
