    Killing Hi/Low servos - End point adjustment?

    Howdy all, I have run through the iPhone app and I see no way to adjust Hi/Low gear servo endpoints.
    I see where it can be reversed but does not have any other adjustments as far as I can find

    The issue I am having is they are driving the servos too far and smoking the boards.

    anyway if anyone has run into this issue and solved it I'd love to hear it.

    Going back to robbing a diff servo until I can get a new one!

    Looking through the manual their is no way of setting the endpoints for the shift/diffloc servo's. Usually the only thing that burns them out is improperly adjusted. They don't need to be out much to burn em out

    Thanks Crock for the confirmation, I have emailed Traxxas support and we will see what happens.

    It's not a mechanical adjustment, the RX is driving the servo too far, I can remove the servo arms, and plug in a servo and flip the hi/low switch one way it's fine, the other way it's over driving the servo past it's limits and the end result is a smoked servo board

    Kinda silly to have EPA on the throttle and steering but not on the other servos.

    I'll see what support has to say hopefully the make good and send another RX if not I'll see what the next step is.

    Thank you! - SomeIT

    Adjusting horn and linkage and making certain there is no obstruction is key.

    Yup I understand that.

    The receiver is over driving the servo, with no method to adjust endpoints.

    The servo with no horn or linkage on it at all is being driven to a point where the servo is being asked to do more than is physically is possible.

    I'll report back once I hear from Traxxas support.

    Thank you!

    No argument that you cannot adjust the end points. You CAN center the servo horns.

    Plus one to Traxxas support, At least for now, it appears to be fixed, First time calling got a guy named Chris who walked me through doing a transmitter reset, Although the EPA is not adjustable on Channel 3 So far at least that has fixed it.
    I have a temp $3.00 servo in place until a replacement comes in and took it for a run and I can shift Hi/Low no issues and it does not appear to be over extending now.

    To do the reset:

    Power off TX
    Hold the top two red buttons down
    Power on
    Power light should slowly flash red
    Hit the SET button once
    Dun

    Obviously this reset all setting to factory.

    Support was so good I think I'll go buy a Slash tomorrow to celebrate :-)

    Just a final update, everything is well and I believe that did the trick.

    Strange because the EPA isn't adjustable through the TX but it worked!

    Thank you Support, great job!
