Jet Rookie Questions: I will be using Spektrum 6020, 6050, and 590 servos in my jet trainer (JetMach 60). My question is are you fellas using metal or plastic servo arms in your jets. If metal, what brand of metal arms are you using? I understand that JR servo arms will fit on Spektrum servos, is that true? My wife purchased the Spektrum servos as a present. She thought she was doing me a great favor so I would be committing social and political suicide if I did not use those servos. She saw where I had made a list of JR and Spektrums and due to her great and well used shopping skills and abilities, she purchased the lesser of the two brands. Got to love her. Any advice would be greatly appreciated. Chic
