Went to fly my 120 sr today and the heli acted like the gyro was not working? Flying very erratic when everything was fine previously.

I noticed a loose wire on the controller that I had not seen before. I took a pic. Notice the copper colored uninsulated wire that exits the board in the corner. IS that supposed to be loose??

TIA

A-rrrr ! Me thinks the bare wire be the antennar !

I'm dealing with treble issues on my mcpx as well.  I tried the crc contact cleaner in the servos- it staightens up for a bit, but then goes back into treble mode. I really don't want to take them apart to clean them as I have seen in some vids, but it looks like I might have to.
Hope this helps.
