I took the one out of the motor to show the hobby shop and they said a OS A3 or A5 are the same type of plug,just need to choose what temp range is required.
As the motor was used it may have had the wrong plug installed,so I may have shown them the wrong sample plug.
The only standard OS plug that is the same is the LC3 Hot plug. OS plugs are short body plugs, they will work but you might be chasing the tune all day long. If you can't get RB or Novarossi plugs get an odonnell or a mccoy and you will be fine.
