How do you toggle between TH and BRK or L and R when setting EPA? I have looked forwards and backwards in the manual. This is a new radio to me. I'm coming from a 3PK. I can get to the adjustment. But I can only adjust the first one highlighted like the BRK and R.

If its stuck on left turn the wheel right and vise versa same with throttle if stuck on that then hit brake and vice versa

I tried all that the first time. And it didn't work. I saw your post so I tried it again. No Go. Then I held it to the left for a couple seconds and it changed So you gotta hold it there for a second or so. Thanks for the post. I was getting pissed.
