    Hi -

    I rebuilt the worm servos and they are still not working when plugged into the X4. I need to run a test to be sure they are getting power from the pins when activated. As well bench test the servos themselves.

    Could someone tell me what the voltage readings should be on the 3 power supply pins for the Worm Drive Servos for the X4 Landing gear inside the body? Starting from front to back of the X4 please.

    In the servo I have White - Black - Red wires to the pins. (I'm not sure if white or red is towards the front of the bird at the moment)
    Center pin is the negative lead correct? (center female pin is a black wire for me in the servo, but I don't want to assume anything as far as color code)

    tia,

    Servo cables are Black, red, white.

    They should be Black = Bottom - Gnd, Red = Middle - VCC, White = Top - Signal.

    over the next two weeks I will be checking the current drain and voltage on the rear worm drive (z-53) I am going to put a fuse or circuit breaker on the active wire that plugs into the main board.
    I will try to post detailed information on what I find with pictures maybe even a video on how to add a fuse and its recommend current rating depending on the results.

    Hey thanks thcinaus,

    In checking, I see that servo is for the Voyager 3 correct?

    I don't think that's the same as on my Scout X4, which is what the question is in reference to. I could be wrong but, part number for the Scout is a Z-21.

    Though I'm sure Voyager 3 owners would benefit from your findings.

    Yeah, I know what standard is.

    Question is in reference to the Scout. And voltage.
    Center is black as stated in the original post.
    Voltage unknown. As well, if they followed standard.

    Reread or read the starting post.
    Then answer. If you know the answer.. otherwise...

    Thanks anyway..

    just waiting for my new 30v 10a power supply to come got one from china but it was only rated at 220volt and when I plugged it in a 6 inch yellow spark jumped out of the back of it and it also blew the rcd finnaly got a refund and have ordered a Aus model with all the protection needed to conform to Aus standards so be warn dont buy cheap Chinese stuff on eBay unless you know its certified for Aus requirements
