Ok, so I never know when to walk away from something....I decided to take my controller apart for the Leopard and try adding a button to it. I use an Aerosprt 5 for that tank as well. I soldered the wires the same as the first time and it works fine....now I am thoroughly confused which...is really nothing new.
I then took apart my Spectrum DX5E and used the existing trainer switch to modify that as the fire button for the main gun. Guess what! It too worked fine. Sooo...any ideas on a possessed radio? LOL
