Thank you! I’ll give that a try.Start over. Horn/arm removed from the servo. Radio ST trim at Zero/Neutral. Servo must be powered ON when setting the arm back onto the servo spline. The only way to know the servo is precisely centered.
Place arm back on, wheels being straight..
Tell us what happened.
If all works out, then you MUST set your Steering Endpoints next!!!
Don't ya HATE when you install a new servo, set everything perfectly to 0 and go to install the horn and its one fuggin spline away from straight either way!? That really burns my arsee..+1
Need your radio's Manual.
Take your time with this procedure. So you understand it and is done correct.
If you don't, this can brick the servo. Once set properly, forget it. It's done. Just do it right once the first time.
