The antenna on mine came dislodged after a couple years and some rough usage.
Did your engine act like mine? Mine will take off like a rocket when I power up the tracks. It won't stay still on the tracks while in the command mode, so I can't program it in with my remote. Could you give me some details about what you did to fix your antenna? I am a novice at this and I just want to do it right.
