    How to run a BEC to power just a single servo?

    Anyone have a diagram on how to wire in a castle creation BEC to power a high torque single servo. I plan to run the servo at 8.4v but if I wire it in the normal way it will fry the micro servos.

    Any help is appreciated.

    Holmes hobbies sells a bypass adapter for this or you can make one.
    ONLY PULL POWER FROM THE BEC SIDE LEADS.(thet usually have the tag on the wires)
    Power and ground from bec and only signal wire from rx to servo.i don't have a diagram search on here im sure there is one here somewhere.lol

    Yeah I ordered something similar from another company. Seems to be better quality. Seems straight forward. Can't wait to see what 900ozs of torque looks like

    Prob need to add a washer or two under the servo saver spring to stiffen it up or the servo will just overpower it.
    I thought about eliminating the servo saver but realized that may not be a good thing.as this is a heavy big truck.
    Get a good quality servo horn its going to get some work

    Yes the stock spring is the heavy duty spring. It will maybe still need it to be stiffer.Try it and see how it does.
    Washers are cheap so if it needs a couple not a big expense.can use whatever works for you.i just used some washers I had laying around.
    Think I ground them down a bit to fit.
    I just realized that was probably close to 10 years ago..lol

    It'll be alright. I was running at 500+ ozs of torque with zero issues. If spacers are needed I'll use them. 900ozs may break some things and may be unreasonable loo
