Hi Bruce. Long time fan and viewer of your channel. I am having a problem with my transmitter and was hoping you or one of your followers can help.
Here is the issue written out. I will post a link to a video so you can see the issue in action.
I have a TH9x transmitter. I have modified it with a Smartie Parts board (smartieparts.com) which made it easy to update the firmware to the ER9x firmware and gave me the backlit feature as well.
The system has been operating beautifully until recently. What is happening is that when flying with a plane with rudder, as I throttle up and give any right rudder the rudder begins to act erratically. I get some left rudder coming into play. Sometimes a little flick of left rudder or sometimes full deflection left rudder. This is happening when holding full right rudder. This link will show the issue on video.

Hope you can help.
Thanks in advance.
