As GruesomeEight explained, your TR’s are not the issue and you likely just need to bind them properly. The problem many of us have been plagued with is the TO/GA button on throttle 1, which becomes frayed over time due to poor routing or insufficient strain relief on those wires. They are extremely small (like 24 or 26 gauge) and it does not take much to fray them.
God you wouldn’t beleive it
My 3rd Bravo unit has developed the same broken wire fault on the second axis from the left.
It’s still under warranty but is such a pain having to have to send it back again
The last two units have failed after about 6 months of use (3-5 times a week for a couple of hours)
I wonder if they have solved this engineer problem?
