4PK-S not zeroing out
 

I don't know if I'm saying this right but on my radio when I go forward and release the trigger the graph on the screen doesn't go completely back to zero, the line is a little thicker than it should be. But if I use the brakes and release it will go all the way back. I tightened up the trigger but don't think it helped. Thanks

Take off the servo horn nd try again, sounds to me like something is binding

is your sub trim zeroed out,in the sub trim menu?
