If from the outside edge it is V+,Gnd,Signal then it is the old style. If it is
Gnd,V+,Signal then it is the new Z type, compatible with Futaba/JR.
JR uses 2 beveled edges for keying, Futaba uses a beveled edge and a tab.
Airtronics FM receivers will work with JR FM transmitters(and vice-versa),
but not Futaba/Hitec.
