1st time rc build

[dmess62]

Tamiya Cowboy thanks for the help. I dont know what EPA is, is it something to do with the endpoint of the servo. I looked through my manual the only thing i saw was for travel lenghth(DX6i) it is set to 100% but still have problems with 1st and third. When I put it in 1st then go to second the servo goes past center, but when i go from 3rd to 2nd it goes back to center. The steering servo horn keeps turning all the way to the left after using a couple of times. If i push stick all the way to the right it centers the tires but stick in neutral position the tires are all the way left. Am I getting too much travel to the point of stopping the horn when it tries to center.

Sorry for all the dumb questions I get confused with all the technical stuff
