Futaba Trainer Cable for Airtronics TX
I have an older Futaba trainer cable with the round plugs with five pins. The plugs fit the Airtronics Vanguard transmitters perfectly. Will the cable work with two Airtronics Vanguard transmitters? I want to ask the question before I try it for fear of burning up a transmitter. Also, may I use an Airtronics Vanguard transmitter without battery, antenna or crystal as a trainer box?
